- 2 large eggs
- 1 cup (240 ml / 8 fl oz) water
- ½ cup (120 ml / 4 fl oz) creamy peanut butter
- ½ cup (120 ml / 4 fl oz) buttermilk
- ½ tsp (2.5 ml / 0.08 fl oz) salt
- 1 tsp (5 ml / 0.17 fl oz) baking soda
- 1 tsp (5 ml / 0.17 fl oz) vanilla extract
- ½ cup (113 g / 4 oz) unsalted butter (for frosting)
- ¼ cup (60 ml / 2 fl oz) creamy peanut butter (for frosting)
- 3 ½ cups (440 g / 15.5 oz) powdered sugar, sifted

Instructions
- Oven Preparation: Preheat oven to 350F (175C) and prepare a 13×18-inch sheet pan with grease or parchment paper for easy cake removal.
- Cake Base Formation: Melt butter in a medium saucepan over medium heat, blend in boiling water, then mix in flour, sugar, and baking soda until smooth.
- Batter Enhancement: Incorporate peanut butter, sour cream, eggs, salt, and vanilla extract, stirring until the mixture becomes uniform and velvety.
- Baking Process: Pour batter into the prepared pan, spreading evenly, and bake for 20-25 minutes until a toothpick inserted in the center comes out clean.
- Frosting Creation: While cake bakes, craft the glaze by melting butter, mixing in milk and cocoa powder until glossy and bubbling.
- Frosting Finalization: Remove from heat, whisk in powdered sugar, additional peanut butter, and vanilla extract until achieving a smooth, shiny consistency.
- Cake Finishing: Immediately pour warm frosting over the just-baked cake, spreading to cover entirely and allowing it to set for 15-20 minutes before serving.
Notes
- Choose High-Quality Ingredients: Select fresh, premium peanut butter and cocoa powder to elevate the cake’s rich, authentic flavor.
- Control Moisture Carefully: Avoid overmixing the batter to prevent a dense, tough texture; stir just until ingredients combine smoothly.
- Monitor Baking Time Precisely: Check the cake at 20 minutes to prevent overbaking, which can lead to a dry, crumbly result; use the toothpick test for perfect doneness.
- Frost While Warm: Apply the frosting immediately after baking when the cake is still warm, allowing it to absorb the glaze and create a more intense, moist texture.
