Step‑by‑Step Instructions for Moist Old-Fashioned Chocolate Cake with Easy Peanut Butter Frosting
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take two round cake pans and either spray them with non-stick cooking spray or line them with parchment paper to ensure easy release. This preparation step is crucial for the success of your chocolate cake with peanut butter frosting.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt. This combination should create a uniform and well-blended dry mix. Give it a thorough whisk for about 2-3 minutes ensuring there are no lumps, setting the foundation for a perfectly moist chocolate cake.
Step 3: Combine the Wet Ingredients
In a separate bowl, combine the large eggs, buttermilk, vegetable oil, vanilla extract, and cold brewed coffee. Whisk these ingredients together until you achieve a smooth mixture, about 2 minutes. This flavorful mixture will enhance the richness of the chocolate cake with peanut butter frosting when combined with the dry ingredients.
Step 4: Combine Wet and Dry Mixtures
Gradually pour the wet mixture into the bowl with the dry ingredients. Carefully fold everything together using a spatula until just combined, making sure to avoid overmixing. You’ll know it’s ready when no streaks of flour remain. Your batter should be smooth and slightly thick, a promising start to a delectable cake.
Step 5: Bake the Cakes
Divide the batter evenly between the prepared cake pans, smoothing the tops with a spatula. Place the pans in the oven and bake for about 30-35 minutes. Keep an eye on them—the cakes are done when a toothpick inserted into the center comes out clean or with a few moist crumbs.
Step 6: Cool the Cakes
Once baked, remove the cake pans from the oven and let them cool in the pans for about 10 minutes. Then, gently run a knife around the edges and invert the cakes onto wire racks. Allow them to cool completely before frosting, ensuring the layers remain moist and ready to absorb the delightful peanut butter frosting.
Step 7: Prepare the Peanut Butter Frosting
In a mixing bowl, beat together the softened butter and creamy peanut butter using an electric mixer on medium speed until smooth and fluffy, about 2-3 minutes. This creamy mixture will provide the ideal texture for frosting your layered cake, setting the stage for that luscious chocolate and peanut butter marriage.
Step 8: Mix in Sugar and Milk
Gradually add the confectioners’ sugar to the peanut butter mixture, incorporating it slowly while mixing. Pour in a splash of milk to reach your desired consistency. Continue mixing until the frosting is light and fluffy, adjusting sweetness to your liking. This frosting will be the crowning glory of your chocolate cake with peanut butter frosting.
Step 9: Frost the Cake
Finally, take one cooled cake layer and place it on a serving plate. Spread a generous layer of peanut butter frosting on top, then place the second layer on top. Frost the top and sides of the cake evenly, creating a beautifully coated treat. Your moist old-fashioned chocolate cake with easy peanut butter frosting is now ready to shine at any gathering!
