A Brief History of Peanut Butter and Chocolate

The pairing of peanut butter and chocolate gained massive popularity in the early 20th century, thanks to the invention of the peanut butter cup by H.B. Reese in 1928. Over the decades, this combination has inspired countless desserts, from cookies and brownies to cakes and ice cream. The balance of sweet, creamy chocolate and slightly salty, nutty peanut butter creates a flavor profile that has remained timeless and beloved by dessert enthusiasts worldwide.

Ingredients

For the Peanut Butter Cake:

  • 2 ½ cups (315g) all-purpose flour
  • 1 tablespoon baking powder
  • ½ teaspoon salt
  • 1 cup (2 sticks, 226g) unsalted butter, softened
  • 1 ½ cups (300g) granulated sugar
  • 1 cup (270g) creamy peanut butter
  • 4 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup (240ml) whole milk

For the Chocolate Ganache:

  • 1 ½ cups (270g) semi-sweet chocolate chips
  • ¾ cup (180ml) heavy cream
  • 1 tablespoon unsalted butter

For the Peanut Butter Frosting (Optional for Layers & Decoration):

  • ½ cup (113g) unsalted butter, softened
  • 1 cup (270g) creamy peanut butter
  • 2 cups (240g) powdered sugar
  • 3–4 tablespoons (45–60ml) heavy cream

Instructions

Step 1: Prepare the Peanut Butter Cake

  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line them with parchment paper.
  2. In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
  3. In a large mixing bowl, beat the butter and sugar together until light and fluffy, about 3 minutes.
  4. Add the peanut butter and beat until smooth.
  5. Mix in the eggs, one at a time, followed by the vanilla extract.
  6. Gradually add the dry ingredients, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined.
  7. Divide the batter evenly between the prepared cake pans and smooth the tops.
  8. Bake for 28–32 minutes, or until a toothpick inserted in the center comes out clean.
  9. Allow cakes to cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.

Step 2: Make the Chocolate Ganache

  1. In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer. Do not boil.
  2. Remove from heat and pour over the chocolate chips in a heatproof bowl. Let sit for 2 minutes, then stir until smooth and glossy.
  3. Stir in the butter for extra shine and richness.
  4. Allow the ganache to cool slightly so it thickens but remains pourable.

Step 3: Make the Peanut Butter Frosting (Optional)

  1. In a mixing bowl, beat the butter and peanut butter together until smooth and creamy.
  2. Gradually add the powdered sugar, mixing well.
  3. Add the heavy cream, one tablespoon at a time, until the frosting reaches a spreadable consistency.

Step 4: Assemble the Cake

  1. Place one cake layer on a serving plate. Spread a layer of peanut butter frosting (if using) on top.
  2. Place the second cake layer on top.
  3. Pour the slightly cooled chocolate ganache over the cake, allowing it to drip down the sides. Use a spatula to smooth the top if necessary.
  4. (Optional) Pipe additional peanut butter frosting around the edges for decoration.
  5. Allow the ganache to set before slicing and serving.

This cake is built with layers of moist peanut butter cake, enhanced by a creamy peanut butter frosting, and finally topped with a rich chocolate ganache that cascades down the sides for an irresistible finish.
