- 1¾ cups (220g) all-purpose flour
- 1¾ cups (350g) granulated sugar
- ¾ cup (75g) unsweetened cocoa powder
- 1½ tsp baking powder
- 1½ tsp baking soda
- 1 tsp salt
- 2 large eggs, room temperature
- 1 cup (240ml) whole milk
- ½ cup (120ml) vegetable oil
- 2 tsp vanilla extract
- 1 cup (240ml) boiling water
- ½ cup (120g) creamy peanut butter
- 2 tbsp powdered sugar
- 2 tbsp milk
- Preheat oven to 350°F (175°C). Grease and flour a 9-inch (23cm) round cake pan.
- In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- Add eggs, milk, oil, and vanilla; beat on medium speed until smooth, about 2 minutes.
- Slowly stir in boiling water until batter is thin and well combined.
- In a small bowl, mix peanut butter, powdered sugar, and milk until smooth.
- Pour half of the chocolate batter into the prepared pan. Dollop half of the peanut butter mixture over it. Pour remaining chocolate batter on top, then dollop remaining peanut butter.
- Use a butter knife to gently swirl the peanut butter into the chocolate batter.
- Bake for 35–40 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
- Cool in pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
Notes
- For an extra peanut butter punch, drizzle melted peanut butter over the cooled cake.
- Ensure ingredients are at room temperature for even mixing.
- Swap whole milk for buttermilk for a tangier crumb.
- Store leftovers in an airtight container at room temperature for up to 3 days.
