These Pineapple Cupcakes are fun and tropical! Pineapple-flavored cupcakes are filled with fresh pineapple and topped with coconut buttercream and toasted coconut. Best of all, they're finished with an adorable buttercream pineapple on top!
This recipe uses pineapple Kool-Aid to flavor the cupcakes, but if you can find pineapple extract or flavoring, you can substitute 1.5 tsp of that instead.
Line 24 muffin tins with cupcake papers and preheat the oven to 350 F. In a small bowl, sift together the flour, baking powder, and salt, and set aside for a moment.
In a large mixing bowl, combine the sugar, room temperature butter, and pineapple Kool-Aid powder, and beat them together on medium speed until light and fluffy, for 3-5 minutes.
Add the eggs, one at a time, beating well after each addition, then add the vanilla extract and mix it in.
Add a third of the flour mixture to the mixing bowl, and mix it in until just a few streaks of flour remain. Add half of the milk, and when it’s incorporated, continue to alternate adding the dry and wet ingredients until everything is added.
Scrape down the bottom and sides of the mixing bowl with a spatula. Spoon the batter into the cupcake liners, filling about 3/4 full. Bake at 350° F for 20-22 minutes. Let cool completely before filling and decorating.
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, 1-2 tablespoons at a time. Once all of the butter is incorporated, add the coconut 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.
Place a few cups of buttercream into a piping bag fitted with a coupler.
Use a sharp paring knife to cut a cone-shaped hole out of the top of the cupcakes. Finely chop the pineapple chunks into small pieces, and scoop a spoonful of pineapple into each hole, almost all the way to the top. Cut the bottom off of the cupcake cones, and replace the top of each cupcake.
Pipe a big swirl of coconut frosting on top of each cupcake. Place a metal spatula in a pitcher of very hot water, to heat the metal, and dry it off so it’s hot but not wet. Press the spatula on top of the buttercream and gently slide it back and forth, using even pressure, so that you flatten out the top of the frosting, creating a round and completely flat frosting surface. Repeat with all of the cupcakes.
Roll the sides of each cupcake in the toasted coconut, keeping the flat tops of the cupcakes clear.
Divide and color the remaining buttercream: color about 1 of the frosting green, and place it in a piping bag with a small leaf tip. Color half of the remaining frosting yellow, and half brown. Lay out a piece of plastic wrap about 16 inches long. Spread a rectangle of brown frosting on the plastic wrap, about 10 inches by 6 inches. Spread the yellow frosting right on top of the brown. 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. Snip off one of the plastic wrap “tails” and insert the frosting cylinder into a piping bag fitted with a round coupler, snipped-side down.
Hold the piping bag perpendicular to the top of the cupcake, and squeeze with even pressure to pipe a cylinder of frosting in the center of the cupcake, about 1-inch tall. After each cupcake has a cylinder, fit the piping bag with a small star tip (I used Ateco #15) and squeeze mini stars all over the frosting cylinder, going all the way around, so that it looks like a pineapple.
Finish by adding green leaves on top of each pineapple. These Pineapple Cupcakes can be kept in an airtight container in the refrigerator for 3-4 days, but for the best taste and texture, serve them at room temperature.
To toast coconut, spread it out on a baking sheet and toast it in a 350-degree oven, stirring well every 3-4 minutes. Exact time will depend on the moisture level of the coconut, but it usually takes about 2-4 cycles of stirring for my coconut to reach a golden brown color.
