Start by making the filling. This is in essence a process of making applesauce using dried apples. You’ll simmer your apples with brown sugar and spices in some water. Once they become soft, you can put them in a food processer to puree.
Next, make up the cake batter by creaming sugar and butter, then add in your buttermilk, eggs, and flour mixture (flour, baking powder, baking soda, salt, cinnamon).
This needs to chill in your fridge for a while. Once it is cold, you can spread it into cake pans. You’re making layers, so they need to be spread into multiple pans. We are using six cake pans with this recipe.
Once your cake pans are filled out, you can take the cake out and spread it on parchment paper and bake them at 350 degrees Fahrenheit for about 25 minutes. When they are ready, the cake will start pulling away from the edges of the paper. Doing this gives you sturdy layers that will cook quickly.
You will have some dry cake coming out of the oven, but that’s expected. Next, you need to put your layers together. Between each layer, spread a generous portion of your apple filling. Once the entire cake is assembled, you need to wrap it tightly and let it refrigerate for at least 24 hours. The longer the better, and if you can leave it in there for a few days, that would be perfect.
Once the cake is ready, you can garnish it with powdered sugar.
