This is fast, colorful, and easy-to-deliver birthday cake is sure to make someone's big day extra special. In fact, it can be made without cake pans or even an oven—you just need a waffle iron.

For this recipe, a white cake mix and vanilla frosting are used. However, you can try it with any flavor of boxed cake mix and with your favorite frosting. A square waffle maker was used, resulting in a square cake that can be sliced into flat pieces. A round waffle maker could also be used for a cake that can be cut into wedges. A thinner, classic waffle iron will yield thinner cake layers with smaller pockets for frosting, while a thicker, Belgian-style waffle maker will yield thicker cake layers with deeper pockets for frosting.

Each layer of the waffle cake is frosted with your choice of homemade or store-bought frosting. Just be sure to make an even layer each time to allow the frosting to fall into the waffle crevices. The cake can be refrigerated to help set the layers before slicing and serving. Top with candles and get ready to sing with delight!

Set the waffle maker to low and watch the cake mix waffles carefully. You don't want the waffles to take on too much color and get too dark, you want the waffles to stay nice and cakey.
