Ingredients
Scale
Main Ingredients:
- 1 box yellow cake mix
- 1/2 cup creamy peanut butter
- 1/2 cup softened butter
- 4 eggs
- 1 cup water
Wet Ingredients:
- 2 tablespoons milk
- 1 teaspoon pure vanilla extract
Frosting Ingredients:
- 3 cups confectioners sugar
- 1/2 cup creamy peanut butter
- 1/2 cup softened butter
Instructions
- Preheat the oven to 325°F (163°C) and prepare a 9×13-inch baking pan with a light coating of grease to prevent sticking.
- In a mixing bowl, blend softened butter and peanut butter using an electric mixer until smooth and fully integrated.
- Incorporate eggs, cake mix, and water into the butter mixture, beating thoroughly for 2 minutes to create a uniform batter.
- Transfer the batter evenly into the prepared baking pan, ensuring a level surface for consistent baking.
- Place the pan in the preheated oven and bake for 40 minutes, checking doneness by inserting a toothpick into the center – it should come out clean when the cake is fully cooked.
- Remove the cake from the oven and allow it to cool completely at room temperature before applying frosting.
- For the frosting, whip softened butter and peanut butter together until creamy and well-combined.
- Gradually fold in confectioners’ sugar, vanilla extract, and initial milk quantity, mixing until the frosting achieves a light, fluffy texture.
- Adjust frosting consistency by adding milk incrementally, creating a spreadable yet stable mixture.
- Once the cake has cooled, generously spread the peanut butter frosting across the entire surface, creating an even layer.
- Slice into squares and serve the decadent peanut butter sheet cake to eager dessert lovers.
Notes
- Adjust oven temperature for even baking by rotating the pan halfway through to prevent uneven browning.
- Opt for creamy peanut butter to ensure a smoother texture and more consistent cake consistency.
- Use room temperature ingredients like eggs and butter to help them blend more seamlessly and create a lighter cake crumb.
- Customize the frosting’s sweetness by gradually adding powdered sugar and tasting as you go, allowing for personal preference.
