Peanut Butter Sheet Cake with Peanut Butter Frosting

Ingredients:

For the cake:

• 2 cups all-purpose flour
• 2 cups sugar
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt
• 1/2 cup peanut butter
• 1/4 cup vegetable oil
• 2 eggs
• 1/2 cup buttermilk
• 1 teaspoon vanilla extract

For the frosting:

• 2 sticks (1 cup) butter, softened
• 3/4 cup peanut butter
• 3 cups confectioners’ sugar
• 3 to 4 tablespoons milk
• 2 tablespoons instant vanilla pudding mix

Instructions:

1. Prepare the Oven and Pan:
   Preheat your oven to 350 degrees F (175 degrees C). Grease a 10x15x1 inch jellyroll pan.
2. Mix Dry Ingredients:
   In a large bowl, combine the flour, sugar, baking soda, and salt. Whisk together to blend evenly.
3. Cook the Butter Mixture:
   In a medium saucepan, combine 1 1/2 sticks of butter and 1 cup of water. Bring to a simmer over medium heat, making sure all the butter is melted. Remove from heat and stir in 1/2 cup peanut butter and vegetable oil.
4. Combine with Dry Ingredients:
   Pour the butter mixture into the dry ingredients. Stir until just combined and smooth.
5. Add Eggs and Buttermilk:
   In a separate bowl, whisk together the eggs, buttermilk, and vanilla extract. Add this to the flour mixture, stirring until well combined.
6. Bake the Cake:
   Pour the batter into the prepared pan. Bake for 22 to 26 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool completely in the pan on a wire rack.
7. Make the Frosting:
   Using an electric mixer, beat the remaining butter and peanut butter until smooth. Gradually add half of the confectioners’ sugar and half of the milk, beating until smooth. Continue adding the remaining sugar, milk, and the vanilla pudding mix, adjusting with a little more milk if necessary, until you achieve a smooth, spreadable consistency.
8. Frost the Cake:
   Spread the frosting evenly over the cooled cake.

Slice, serve, and enjoy the ultimate peanut butter treat! This cake is best enjoyed with a tall glass of milk or a cup of coffee, making it the perfect dessert for any peanut butter lover’s feast.
