If you've never made a cookie cake, you're in for a treat. This cinnamon-kissed iteration is surprisingly easy to assemble!
You can use either 8- or 9-inch cake pans for this recipe. Using 8-inch pans will result in a taller cake, while using 9-inch pans will result in a wider cake.
If you don't have 3 cake pans, you can bake the layers in shifts. Be sure to grease and line with parchment before baking each layer.
