Super Tall Spring Layer Cake

I’m not sure how to say this without sounding conceited, but I am obsessed with how this cake turned out. OB-SESSED. I know it’s not a great look to pat yourself on the back on your own blog, but I can’t help it…I’m seriously smitten with this super-tall cake!

I’m calling it a “Spring in Bloom Layer Cake” because everything about it just screams SPRING to me. From the moist vanilla cake layered with lemon curd and raspberry jam to the riotous rainbow of flowers bursting from the base of the cake, it makes me grin like a fool every time I look at it. And if that isn’t the ultimate function of a dessert, I don’t know what is. Desserts should make us HAPPY, and this cake definitely delivers on that front.

Equipment You’ll Need

I have a few tricks to making this cake. Well, the first one isn’t a trick so much as an important piece of equipment. I made the flowers using Russian Piping Tips, which I’ve talked about on Facebook Live and Instagram quite a bit.

If you’re not familiar with them, they’re large piping tips that are designed to produce frosting flowers with just 1 squeeze of the piping bag. It’s genius! They come in all sorts of different designs, so if you buy a set you can produce a number of different flowers quickly and easily. I bought this set, which has 7 different tips, and if you look at the picture below you can see some of the variety of different shapes of flowers available.

How to Fill the Piping Bags

The second trick to making the flowers look amazing is this technique for filling piping bags. Up until recently, I’ve always done things the old-fashioned way: by using a spatula to stuff different colors of frosting into a piping bag. It works, to a point, but it’s sometimes messy and hard to predict the final outcome of the flowers.

But now I’ve started using a piece of plastic wrap and layering my frosting colors on that. Once the frosting is rolled up and stuffed into the piping bag, it pipes like a dream. The best part is, it’s really easy to control how the final flowers look—you’ll know what colors will be on the inside and outside, and in what proportions. More bonuses: it also keeps your piping bags much cleaner, and it’s easy to switch between colors. Win-win-win! So that explains why all of my flowers have 4-5 different colors in each bloom–I went crazy with this technique!

Make the Flowers in Advance

I made all the flowers in 1 marathon session, and piped them directly on a baking sheet covered with waxed paper. After the flowers were piped, I refrigerated the sheet to chill them. They get REALLY hard, which makes it easy to pop them off the baking sheet and transfer them to the side of the cake.

There are a lot of benefits to this method: you are working with firm flowers, so there’s less chance of accidentally smooshing them. You can easily control placement, and move them around if necessary, and also you can make sure that similar flowers are not all clumped together. And while you CAN pipe directly onto the sides of a cake, the angle makes it difficult to get perfect flowers, so doing it on a flat baking sheet will probably be much less frustrating and more successful for you.

Finally, you can make these in advance! So if you’re attempting this cake, you’ll be able to break up the work into multiple days, which is always a godsend when assembling a big cake.

How to Assemble the Spring In Bloom Cake

So the actual decorating went like this: slap some white frosting on the cake, using rough strokes to resemble tree bark. (Another bonus: no need to slave over getting smooth frosting!) Add streaks of gray, because we’re going for that birch tree look. Pop those pre-made flowers onto the cake, and finally, fill in with some green leaves here and there—basically wherever the cake looks a little naked.

Stand back, give yourself a giant pat on the back, then post a million Instagram stories to have other people give you pats on the back as well.


And here’s an inside view of the cake! I assembled it with cake boards and dowels, since the fillings were a little soft and I was worried about the stability of the cake otherwise. The great thing about this method, aside from peace of mind, is that it’s really easy to slice the cake into manageable, not-too-giant slices when it’s actually time to serve it.

Although the cake is giant and a bit over-the-top, the slices themselves are reasonable, and the lemon and raspberry flavors make it very light and refreshing. This is absolutely a cake to feed a big crowd, although you could always half it (or just use the technique with a different recipe!) to make more manageable servings.

To Make the Cake:

  • Preheat the oven to 350 F. Line three 6-inch cake pans with parchment rounds, and spray the parchment and pan sides with nonstick cooking spray.
  • Combine the sugar, cake flour, baking powder, baking soda, and salt in the bowl of the stand mixer fitted with a paddle attachment. Mix on low speed for about a minute to combine the dry ingredients.
  • Lightly whisk together the eggs, a quarter of the sour cream, and the vanilla extract, and set aside for now.
  • Add the remaining sour cream and the softened butter to the large mixing bowl, and mix on low speed until the dry ingredients are moistened. Turn the mixer to medium speed and mix for a minute and a half.
  • Add the egg mixture in three batches, mixing for 20-30 seconds after each addition, until you have a smooth batter. Scrape the bottom and sides of the bowl with a rubber spatula, and give the batter a few more stirs to make sure everything is incorporated.
  • Divide the batter between the three pans and bake at 350 F for 35-40 minutes, until the sides just start pulling away from the pan, and a toothpick inserted into the center comes out clean.
  • Let the cakes cool on a wire rack for 10 minutes, then gently turn them out and let them cool completely. I find it’s easiest to cut and stack cakes that have been chilled, so if you have time, wrap them with plastic wrap and put them in the freezer for at least 30 minutes, until they are firm but not frozen all the way through. If you are making these in advance, they can stay in the freezer for up to several weeks. Let them partially defrost, until they are firm but not rock-hard, before assembling.

To Make the Buttercream:

  • Combine the whites, powdered sugar, and salt in the bowl of a large stand mixer fitted with a paddle attachment. Mix everything together on low speed, until the sugar is moistened and no dry patches remain. Turn off the mixer, scrape down the sides and bottom of the bowl with a spatula, then turn the mixer to medium speed. Beat on medium for 5 minutes.
  • After 5 minutes, turn the mixer to medium-low and start adding the softened room temperature butter, a few tablespoons at a time. Once all of the butter is incorporated, add the vanilla extract and mix it in. Stop the mixer and scrape down the bottom and sides once more. Turn the speed to medium and beat the buttercream for 10 minutes. At the end, you’ll have a frosting with a wonderfully light and creamy texture.

To Make the Flowers:

  • Remove about 4 cups of frosting and set aside—this will be the white frosting used to decorate the cake.
  • Color 1 cup of frosting green for the leaves, and set aside for now.
  • Divide and tint the remaining frosting different colors for the flowers. You can do as many or as few colors as you like, but for a really beautiful assortment, I recommend a variety of at least 5-6 different colors for the flowers.
  • Cover a baking sheet with waxed paper or parchment paper.
  • To make multi-colored flowers, lay out a piece of plastic wrap about 16 inches long. Spread a rectangle of frosting on the plastic wrap, about 10 inches by 6 inches. Take a second color of frosting and spread it on top of the first. If desired, add a third or even a fourth color on top. Roll the frosting over itself to make a cylinder. Grasp the ends of the plastic wrap in each hand, and twirl it quickly so the frosting is burrito-shaped and the ends of the plastic are tightly twisted.
  • Fit a large piping bag with one of your Russian piping tips. Snip off one of the plastic wrap “tails” and insert the frosting cylinder into the piping bag, snipped-side down.
  • Hold the piping bag perpendicular to the baking sheet, about ½-inch above the sheet. Squeeze with steady pressure until the frosting comes out and forms a flower shape. Stop squeezing, then lift the tip so that the frosting tapers off into flower petals. Repeat until you run out of frosting, then make another plastic wrapped packet with different colors, and use a different tip. Repeat this process until the baking sheet is filled with an assortment of flowers of different colors and shapes. Refrigerate the tray for about an hour, until the flowers are very firm.

To Assemble:

  • Place the cake rounds on cardboard cake circles. Using a large serrated knife and a gentle sawing motion, slice each cake round into 3 layers.
  • Fit a piping bag with a coupler or a large round tip, and fill it with white buttercream. Place the base layer of one of the cakes on a cake turntable. Pipe a circle of frosting around the outside edge of the cake layer. Fill the layer with lemon curd, spreading it to the edges of the frosting circle—the frosting acts like a barrier to prevent the lemon curd from seeping through the edges of the cake.
  • Top the cake round with a second cake layer, and make a second frosting circle around the edge. This time, fill the inside of the cake with raspberry jam all the way to the edge.
  • Top the cake with the third cake layer. Cover the top and sides with a very thin layer of frosting—this is the crumb coat, which locks crumbs into the frosting and also provides some stability to the cake.
  • Set the first cake aside, and repeat the procedure with the second and third cake layer. At the end, you should have 3 assembled 6-inch cakes on cake cardboards.
  • To tier the cake, we’ll use dowels between the layers to add support. You can use “real” cake dowels, lollipop sticks, or even extra-large straws (like boba tea straws.) Push 4 dowels or straws into one of the cakes in a rough square shape, pushing them all the way down until they hit the cake cardboard on the bottom. Leave a few inches between each dowel to help distribute the weight. Using a marker, make a mark on each dowel to show where the top of the cake hits, pull it out of the cake slightly, then cut the dowel with scissor right where your mark is. Push it back down into the cake—it should be flush with the top of the cake, not sticking out. Add a squirt of frosting on top of the cake in between the dowels, then carefully place a second layer on top of this base layer.
  • Repeat the dowel process with the second layer, until you have 3 cakes stacked on top of each other. Add a thin layer of frosting along the sides to smooth it out, then refrigerate the cake for an hour, until the crumb coat is very firm.
  • Once firm, it’s time to decorate! Add a thicker layer of white frosting all along the top and sides of the cake. Use rough horizontal strokes with your offset spatula to create the texture of tree bark going along the sides of the cake. Tint a small amount of frosting to a dark gray, and add dark gray streaks along the sides and top to give it a birch pattern.
  • Remove the tray of buttercream flowers from the refrigerator, and use an offset spatula to slide them off of the baking sheet and press them onto the freshly frosted cake in whatever pattern you desire. If you work quickly, you can do it all at once, but if the flowers start to get too soft, return them to the refrigerator or freezer to firm up before continuing.
  • Finally, fit a piping bag with a leaf tip and fill it with green frosting. Add leaves in between the flowers and along the edges.
  • For the best taste and texture, serve this cake at room temperature.

Recipe Notes

A note about quantities: this cake calls for a LOT of buttercream. There is a good chance you won’t use all of it for this cake, so if you find yourself with some left over, it can be kept in the refrigerator for up to a month, or in the freezer for up to 4 months. 
I call for a lot of buttercream because it gives you more flexibility in the assembly and decorating of the cake. If you’re new to Russian piping tips and are not quite comfortable with them yet, you’ll have extra buttercream to practice with. If you decide you want to cover the whole cake with flowers, you’ll have enough to do that. Basically, it doesn’t hurt anything to have excess buttercream, and it can be quite annoying to find that you’re short on frosting when you’re in the middle of decorating, so I try to err on the side of having extra.

  1. We all ooohed and ahhed over this, and then I found the Russian piping tips on sale over at Amazon!!! Very excited! I’m going to pipe some less-fancy cupcakes today and thought I’d use your technique, but am not quite sure I get it – have you folded over the frosting then rolled the edges of the plastic wrap together?

  2. Ugh, ignore me! Read through and answered my own silly question! Our three-toned frosting looked great on cupcakes, and I’ll definitely use your trick again. Thank you!!

  3. Unbelievable. Can your cakes be ordered and sent? I now have decided to takes cake decorating class. They are absolutely beautiful

    1. Thank you so much, Ferne! I actually don’t sell my desserts–just provide recipes and instructions so others can make them. 🙂 If you haven’t already, I’d love for you to join me on Facebook for some of the Facebook Live sessions I do! The ones on Sundays are typically cake decorating, and you can see some examples of past classes here, if you scroll through the “SugarHero Show” tab:

      I also have a cake decorating video course through Craftsy that you might like! It’s aimed at beginners, and you can see the trailer and read more about it here:

      I am so happy to have you here in the SugarHero community!

  4. Absolutely amazing! And the colors are so gorgeous! I’ve been looking at the Russian tips for several weeks now but there are so many choices, I was confused. Then when I saw your link, I ordered the set you mentioned. I also ordered silicon cupcake baking cups that look like terra cotta pots. How cute will that be with the Russian tip flowers on them. I’m so excited – thanks so much for sharing your creative, outstanding cake! I also signed up for your emails, and just now took a look at your website. Your recipes are so unique!

    1. Thank you so much! It is so encouraging to hear feedback like this, so I really appreciate it. I’m glad you got those tips! They’re amazing. Definitely some of my favorites. And those little pots sound so adorable. I would love to see how they turn out! I hope you enjoy everything. Thank you for sharing! 🙂

  5. Hi, your cake, your technique using Russian tips and your frosting for making these flowers, all is one of the best and the most perfect I ‘ d ever seen. Thank you. So much for sharing.

    1. Hey Margarita, I am guessing you are talking about the buttercream. If I am wrong just let me know. On the post I have a video which can be helpful when looking for the texture you are supposed to end up with. It wont be like American buttercream if that is what you are used to however it should hold its shape nicely. I hope that watching the video can help with clarification. Don’t hesitate to send me an email though if you have more question and want help troubleshooting! Thanks!

  6. This looks amazing. I’m wondering can the decorated cake be frozen? I wanted to make this in advance (2 weeks) for my moms birthday which I cannot be there for. If not, can the flowers be frozen for that time?

    1. Hey Tasneem, Yes the flowers can absolutely be frozen in advance. What I do is, I will pipe them onto parchment paper onto a baking sheet then once frozen move them to a air tight container. As for the cake being fully decorated and frozen afterwards it is possible. I find that it won’t taste as fresh but it is possible. So if you wan’t to have it at its best when serving I wouldn’t recommend it however it will keep fine frozen. Happy Birthday to your mom!
