This Chocolate Orange Cake is the ultimate cake for chocolate-orange lovers! Moist chocolate cake layers are brushed with an orange syrup, and filled with a bright, tangy orange buttercream. It's topped with a shiny chocolate glaze and chocolate orange slices.
This recipe calls for pasteurized egg whites. It is safe to consume egg whites without cooking them, as long as you make sure that the whites you buy are pasteurized. To save time, I buy them in a carton--look for 100% egg whites, not liquid egg substitute. If you cannot find them in a carton, you can buy pasteurized eggs and separate them yourself. You’ll need about 5-6 large eggs to get the ¾ cup called for in the recipe.
