Colored cake layers are a fun surprise when the cake is sliced. You can make pastel layers, rainbow layers, team color layers, or holiday color layers.
A batch of cake batter usually makes two round cakes, so you can divide the batter into two colors for a simple two-layer cake. For more layers, prepare extra batter or bake in smaller batches.
After the layers cool, place the bottom layer on a cake plate, add frosting or filling, and stack the next layer. Learn more about this step on the how to fill cake layers page.
A marble cake is made by dropping two or more colors of batter into the same pan and gently swirling them together before baking. This creates a colorful swirled look inside the cake.
For example, you can make a Fourth of July cake by adding red and blue batter to white batter and gently swirling the colors together.
Colored cake batter can be used for rainbow cupcakes, holiday cakes, birthday cakes, school color cakes, sports team cakes, or themed party desserts.

Yes. White cake batter can be colored with food coloring or food gel to make colored cakes, rainbow cakes, marble cakes and rainbow cupcakes.
White cake batter works best because it shows the colors clearly. Yellow cake batter can also be colored, but the final colors may look warmer or softer.
Start with a very small amount of food coloring and mix it in. Add more only if a deeper color is needed.
To make marble cake batter, drop two or more colors of batter into the pan and gently swirl with a knife or skewer before baking.
