Ingredients

Scale
  • 1 ¾ cups (220 g) all-purpose flour
  • 1 cup (200 g) granulated sugar
  • 1 tsp baking powder
  • ½ tsp baking soda
  • ¼ tsp salt
  • ¾ cup (180 ml) buttermilk, room temperature (or milk + 1 tsp vinegar)
  • ½ cup (120 ml) vegetable oil (neutral flavor)
  • 2 large eggs, room temperature
  • 1 cup (250 g) creamy peanut butter
  • 1 tsp vanilla extract
  • 1 cup (240 ml) heavy cream
  • 8 oz (225 g) semi-sweet or dark chocolate chips or chopped chocolate
  • 1 tbsp unsalted butter
  • Crushed Reese’s Peanut Butter Cups (optional garnish)
  • Chopped roasted peanuts (optional garnish)

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 9-inch round cake pans and line bottoms with parchment paper.
  2. In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
  3. In a separate bowl, whisk buttermilk, vegetable oil, eggs, peanut butter, and vanilla extract until smooth and glossy.
  4. Slowly fold wet ingredients into dry ingredients with a rubber spatula until no dry streaks remain. Do not overmix.
  5. Divide batter evenly into prepared pans. Tap pans lightly to release air bubbles.
  6. Bake for 25-30 minutes until a toothpick inserted in the center comes out clean and cake springs back when pressed.
  7. Cool cakes in pans for 10 minutes, then invert onto cooling racks to cool completely.
  8. Heat heavy cream in a small saucepan over medium heat until it begins to simmer. Remove from heat and pour over chocolate in a heatproof bowl. Let stand 2 minutes, then stir until smooth and glossy. Stir in butter until melted.
  9. Place one cake layer on serving plate. Spread a thin layer of ganache over it, then top with second cake layer.
  10. Pour remaining ganache over the top, letting it drip down the sides. Smooth with an offset spatula if needed.
  11. Sprinkle crushed Reese’s cups and chopped peanuts on top.
  12. Chill cake for at least 30 minutes to set ganache before slicing.

Notes

Bring all ingredients to room temperature for best results. Gently fold peanut butter into wet ingredients to keep batter light. Cool cakes completely before applying ganache to avoid melting. If ganache thickens, warm gently to restore pourable consistency. Avoid overmixing batter to prevent dense cake. Can be made gluten-free or dairy-free with substitutions.
