Cakes dome on top because the edges of the cake bake faster than the middle causing the top to dome up as it bakes. Luckily, there are a couple of solutions! To stop your cakes from doming, use bake even strips. These fabric strips insulate the cake pan sides, so your batter cooks evenly. If you don’t have the strips, wait for it to completely cool. Once cooled, use a serrated knife to slice off the dome to create a flat surface on the top of your cake. Do this carefully, so you slice evenly.
