Peanut Butter Sheet Cake is perfect for your summer cookbooks, BBQ’s and potlucks. Summer is still going strong and so is this peanut butter sheet cake.
Sheet cakes are the perfect summer dessert. They are easy to make, taste great and feed a crowd. Summer is heating up here in the Pacific NW and we’ve had record breaking temperatures. Summer arrives late here but when it does, it arrives!
Nothing beats a good sheetcake for a summer cookout or potluck. Texas Sheet Cake is a classic for summer BBQ’s and I love my Almond Sheet Cake too. Today’s recipe for Peanut Butter Sheet Cake is another one to add to the sheet cake repertoire. It really rounds out the flavor selection.
I served this recently at a neighborhood get together and the first question asked was , “Is the recipe on the blog?” When I told them it wasn’t yet, the reply was, “it better be soon!” I think they liked it!
I use my big 10 x 15″ jelly roll pan. Everyone needs at least one of these in their kitchen. I have four! The recipe calls for buttermilk which I prefer but if you don’t have any, regular milk will do or make your own by adding some vinegar to the milk. Use 1 Tbsp vinegar to 1 cup milk to make your own buttermilk.
Always frost a sheet cake warm. The frosting soaks into the cake a bit which is so yummy.
I don’t know about you, but I can’t seem to eat peanut butter without chocolate so I added a chocolate drizzle to the top of the cake. I just melted some chocolate chips but you could also use some fudge sauce if you have it hanging around! Non-chocolate lovers (is there such a thing?), can leave it off and add some crushed peanuts for nice touch to the top too with or without the chocolate drizzle. Or go all out and add both the chocolate drizzle and the crushed peanuts.
Has summer wrapped up for you or is it still going strong?

Sorry, I only see buttermilk in cake base which you say toad after hot mixture added to dry ingredients. Am I supposed to put the buttermilk in pan with butter and peanut butter? I only see regular milk in frosting, help!
Leigh Anne Wilkes says
The cake has buttermilk in it and you add it in with the egg and vanilla as step 4 states. The regular milk is used in the frosting in step one.
