My girlfriend makes this awesome peanutbutter tastykake 'Tandycake'. Unfortunately, she WILL NOT give out the recipe (I've been trying for 4 years now!). Is there anybody who has it or something similar? It is made with a thin white cake in a shallow jelly roll pan (but it doesn't taste like a boxed mix), has a thin layer of peanutbutter on top and then melted chocolate for the frosting. I hope someone can help!
