Yes, this recipe can be adapted to make a layer cake. While it hasn’t been specifically tested as a cake, the ingredients and proportions are very similar to other cake recipes, so it should work well. Simply pour the prepared batter evenly into two 8-inch round cake pans and bake at 350°F (177°C). Begin checking for doneness around the 35-minute mark by inserting a toothpick into the center—if it comes out clean or with a few moist crumbs, the cakes are ready.
For the frosting, the piping was done using an Ateco #829 tip, which creates a beautiful, textured swirl on top of each cupcake.
If you’d prefer to top the cupcakes with a simpler chocolate buttercream, you can easily swap out the espresso frosting for one of these two options: a rich and classic Double Chocolate Buttercream, or a lighter, airier Whipped Chocolate Buttercream Frosting.
The finished cupcakes will stay fresh for several days when stored properly. Keep them in an airtight container at room temperature to prevent them from drying out and to maintain their soft, moist texture.
