Description
A delicious peanut butter chocolate cake topped with chocolate frosting.
Ingredients
Scale
- ½ cup unsalted butter
- 1 cup water
- ½ cup peanut butter
- 2 cups sugar
- 2 cups all-purpose flour (for gluten free I recommend Cup4Cup gluten free flour)
- ½ teaspoon baking soda
- ½ teaspoon salt
- 2 eggs
- ½ cup milk
- 1 teaspoon vanilla extract
- ½ cup (1 stick) unsalted butter
- 6 tablespoons unsweetened cocoa powder
- 6 tablespoons sour cream
- 1 teaspoon vanilla extract
- 3 ½ cups powdered sugar
- ¼ cup chopped peanuts (optional)
Instructions
- Preheat oven to 350ºF. Grease a 10X15″ jelly roll pan. (For 9X13″ pan see recipe notes.)
- In a large saucepan melt butter over medium heat. Add water and peanut butter and bring to a boil. Remove from heat and stir in sugar. To the saucepan add flour, baking soda, and salt. Stir until well blended.
- In a small bowl or large liquid measuring cup, whisk together eggs, milk, and vanilla extract. Add liquids to saucepan and stir until very well combined and smooth.
- Pour into prepared pan and bake 23-25 minutes, rotating pan once during baking. Cake is done when a toothpick inserted in middle comes clean. (For 9X13″ pan see recipe notes).
- During the last few minutes of baking, make the chocolate frosting. In a medium saucepan add butter and cocoa powder. Stir together over medium heat until butter melts and mixture is very smooth.
- Remove from heat and stir in sour cream and vanilla extract. Gradually stir in powdered sugar until frosting is smooth and no lumps remain.
- Immediately pour on warm cake and spread evenly. Immediately sprinkle on optional chopped peanuts. Eat warm to experience cake heaven.
Notes
- For a 9X13″ pan, bake time may vary; check for doneness.
- Optional chopped peanuts can be omitted if desired.
