This recipe was converted for home use from one the cafeteria ladies at school gave me many years ago. It is a favorite because it is delicious and easy to make.

These were really good. They taste like peanut butter cookies in cake form. Like another person said they're more of a cake than chewy but they were good. Read More

I used the thinnest pan I could. Must not have been a jelly roll pan. I had to bake it a little longer to make sure it was done. The directions for the frosting did not work out at all! I had to add more milk than the recipe called for to even make a frosting! I used my past knowledge of cake baking to help me. The taste for this cake is not bad. Read More
