Decadent Peanut Butter Sheet Cake with Creamy Peanut Butter Frosting

Instructions

Preheat your oven to 350 degrees and grease a 10x15x1 inch jellyroll pan.

In a large bowl, whisk together the flour, sugar, baking soda, and salt.

Next, combine 1 1/2 sticks of butter and 1 cup of water in a medium saucepan and bring to a simmer. Stir to ensure all the butter is melted.

Whisk in the 1/2 cup of peanut butter and vegetable oil into the butter mixture. Then, stir this into the flour mixture.

In a separate bowl, whisk together the eggs, buttermilk, and vanilla extract. Stir this into the flour mixture until well combined.
