Peanut Butter "Texas" Sheet Cake

Megan Stewart


Mom used to make me Cookie Sheet Cake (aka Texas Sheet Cake by my mother in law) when she was sick, and we would take it out into the backyard and have a picnic together.
This recipe is very similar to that wonderful ooey gooey chocolate cake, only with peanut butter! I took this to my mother in law's house for Easter in 2012, and it went so fast...a wonderful peanut butter cake that will have you licking your chops and fingers too!
In fact, my sister in law remembered it so well, she asked for it again in 2018...very little was left (except the pan to lick)!
