Ingredients:

For the Cake:

• 2 cups all-purpose flour
• 2 cups granulated sugar
• 1 cup unsalted butter
• 1 cup water
• 1/4 cup unsweetened cocoa powder
• 1/2 cup sour cream
• 2 large eggs
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 1 teaspoon vanilla extract

For the Peanut Butter Frosting:

• 1/2 cup unsalted butter, softened
• 1 cup creamy peanut butter
• 4 cups powdered sugar
• 1/4 cup milk (plus more as needed)
• 1 teaspoon vanilla extract

Instructions:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.
2. Make the Cake Batter: In a large bowl, whisk together the flour, sugar, baking soda, and salt. In a medium saucepan, combine the butter, water, and cocoa powder. Cook over medium heat, stirring constantly, until the butter is melted and the mixture is smooth. Remove from heat and let cool slightly.
3. Combine Wet and Dry Ingredients: Pour the cocoa mixture into the dry ingredients and stir until just combined. Add the sour cream, eggs, and vanilla extract, and mix until smooth.
4. Bake the Cake: Pour the batter into the prepared baking pan and smooth the top with a spatula. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely in the pan on a wire rack.
5. Prepare the Peanut Butter Frosting: In a large mixing bowl, beat together the softened butter and peanut butter until creamy. Gradually add the powdered sugar, one cup at a time, beating well after each addition. Add the milk and vanilla extract, and continue to beat until the frosting is smooth and spreadable. If the frosting is too thick, add more milk, one tablespoon at a time, until the desired consistency is reached.
6. Frost the Cake: Once the cake has cooled completely, spread the peanut butter frosting evenly over the top of the cake.
7. Serve: Slice the cake into squares and serve. Enjoy the rich, peanut butter-chocolate goodness!
