Peanut Butter Sheet Cake is a moist sheet cake topped with a super creamy and sweet peanut butter icing. It is a peanut butter lover’s dream and perfect for potlucks and picnics.

Peanut butter is practically the only food I can eat every single day and not get tired of. I often start my day with a banana and a spoon full of peanut butter. I absolutely love the stuff.

Normally when it comes to desserts, I prefer peanut butter paired with chocolate. AKA the best thing ever.

But sometimes a pure peanut butter dessert is just what I’m craving.

With peanut butter in the cake batter and the icing, there’s plenty of peanut butter flavor in this peanut butter sheet cake. It’s like the peanut butter version of a Texas Sheet Cake.
Super Moist Cake Batter

Too often peanut butter cake is dry in texture. This one is super moist. Be sure to measure the flour correctly and use a shelf-stable creamy peanut butter such as Jif or Skippy.

Light and Fluffy Peanut Butter Frosting

The frosting is what makes this dessert truly amazing. The addition of two tablespoons of instant vanilla pudding mixture creates a wonderful texture in the frosting and helps stabilize it.

How To Serve

It’s baked in a 10×15-inch pan and can easily be cut into 20 pieces so it is perfect for bringing to a summer potluck or picnic. If you want to dress it up a little, cut it into squares and then place a mini peanut butter cup on top of each one.
