It would be impossible to keep count of all time times this Heath Bar Birthday Cake has been requested in my mama's house, not only for birthdays but also for holidays, parties of all kinds. And sometimes just because someone or another has a sudden and urgent need for a light and lovely angel food cake frosted with a decadent creamy frosting filled with crushed bits of Heath bars, which are toffee candy bars covered in chocolate (and you can also get them in packages of baking bits, too). I'm pretty certain that my mama goes all in and makes the angel food cake herself, but whenever I'm the one making it I go for the pre-made angel food cake from the market, and spend my time making the delectable frosting. Which means this cake is all of five ingredients, with no baking and maximum dramatic creamy Heath Bar deliciousness. Let's make it!
