Old-Fashioned Peanut Butter Cake

Ingredients:

For the Cake:

  • 1 1/2 cups all-purpose flour
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1/2 cup unsalted butter, softened
  • 1 cup creamy peanut butter
  • 1 cup granulated sugar
  • 1/2 cup brown sugar, packed
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1 cup buttermilk (or 1 cup milk + 1 tbsp lemon juice as a substitute)
  • 1/2 cup hot water

For the Peanut Butter Frosting:

  • 1/2 cup unsalted butter, softened
  • 1 cup creamy peanut butter
  • 3 cups powdered sugar
  • 1/4 cup milk (or more, as needed for consistency)
  • 1 tsp vanilla extract
  • Pinch of salt

Optional Garnish:

  • Chopped peanuts
  • Chocolate drizzle

Instructions:

  1. Preheat the Oven:
    • Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line them with parchment paper.
  2. Make the Cake:
    • In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
    • In a large mixing bowl, beat the softened butter, peanut butter, granulated sugar, and brown sugar until smooth and fluffy, about 2-3 minutes.
    • Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract.
    • Alternately add the dry ingredients and buttermilk, beginning and ending with the dry ingredients. Mix until just combined.
    • Finally, add the hot water to the batter and mix until smooth. The batter will be thin, but that’s normal.
    • Divide the batter evenly between the two prepared cake pans.
  3. Bake the Cake:
    • Bake for 25-30 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
    • Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely.
  4. Make the Peanut Butter Frosting:
    • While the cake cools, make the frosting. In a large bowl, beat together the softened butter and peanut butter until smooth and creamy.
    • Gradually add the powdered sugar, one cup at a time, mixing well after each addition. Add the milk as needed to achieve your desired frosting consistency.
    • Stir in the vanilla extract and a pinch of salt, then beat until the frosting is fluffy and smooth.
  5. Assemble the Cake:
    • Once the cakes are completely cool, place one cake layer on a serving plate. Spread a layer of frosting on top.
    • Add the second layer of cake and frost the top and sides with the remaining peanut butter frosting.
  6. Optional Garnish:
    • Garnish with chopped peanuts or drizzle with melted chocolate for an extra touch.
  7. Serve:
    • Slice, serve, and enjoy this rich, moist peanut butter cake!

Tips:

  • Storage: Store leftover cake in an airtight container at room temperature for up to 3 days, or refrigerate it for up to 1 week.
  • For Extra Moisture: If you prefer a moister cake, you can brush the cake layers with a simple syrup (1/4 cup sugar dissolved in 1/4 cup water) before frosting.
  • Add Chocolate: For a chocolate-peanut butter combo, you can drizzle melted chocolate over the frosting or even mix some cocoa powder into the cake batter.
