Here is my cake, yes I bake. It is actually the Betty Crocker yellow gluten free cake mix. So easy and fast, I make this all the time. When I want it to be special I "frost" it with semi-sweet mini chocolate chips. It's a trick to get them to stick all over, they like to roll off the top to the sides.
I'll just say it requires patience, a fast hand and a few toothpicks.
