For one of Jax's birthday cakes, I thought it would be fun to do a sheet cake with one of his favorite flavors... peanut butter! I loved the idea of making a sheet cake. The thin cake makes it so people could just have a little bit if they wanted or as much as they please. Plus I could pile it high with white chocolate buttercream! A few sprinkles around the side and a birthday cake is born.
This sheet cake doesn't take any special equipment. Just a sauce pan, a couple of bowl and the sheet cake pan. No need for the mixer, which is good because I only wanted to wash it so many times for this one party!!
