By I made peanut butter cake bars for a Tilford-family birthday Saturday. Peanut-butter cake batter baked in a 9-by-13, frosted with a peanut-butter-cream-cheese frosting. Reimbursement $30 tip $20.
The recipe is below.
Peanut Butter Cake Bars
Prep Time: 15 minutes | Cook Time: 25 minutes | Total Time: 40 minutes | Servings: 16
Ingredients
- 2 cups all-purpose flour
- 2 cups granulated sugar
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup butter
- 1 cup water
- 1/2 cup creamy peanut butter
- 2 large eggs
- 1/2 cup sour cream
- 1 teaspoon vanilla extract
For the frosting:
- 1/2 cup butter
- 1/3 cup creamy peanut butter
- 1/4 cup whole milk
- 3 cups powdered sugar
- 1 teaspoon vanilla extract
- 1/2 cup chopped peanuts (optional, for topping)
Instructions
- Preheat the oven. Set your oven to 350°F and grease a 15x10-inch jelly roll pan or a 9x13-inch baking pan.
- Mix the dry ingredients. In a large bowl, whisk together the flour, sugar, baking soda, and salt. Set aside.
- Heat the wet base. In a medium saucepan, combine the butter, water, and peanut butter. Bring to a boil over medium heat, stirring until smooth. Remove from heat.
- Combine. Pour the hot peanut butter mixture over the dry ingredients and stir until just combined. Add the eggs, sour cream, and vanilla extract, and mix until the batter is smooth.
- Bake. Pour the batter into the prepared pan and spread evenly. Bake for 22–25 minutes, or until a toothpick inserted in the center comes out clean.
- Make the frosting. About five minutes before the cake is done, combine the butter, peanut butter, and milk in a saucepan over medium heat. Stir until melted and smooth. Remove from heat and stir in the powdered sugar and vanilla until creamy.
- Frost while warm. Pour the frosting over the warm cake and spread evenly. Sprinkle with chopped peanuts if desired.
- Cool and cut. Let the bars cool completely in the pan before cutting into squares.
