Peanut Butter Cup Cake this Recipe

Ingredients:

  • 1 ¾ cups all-purpose flour
  • 1 cup granulated sugar
  • ½ cup unsweetened cocoa powder
  • 1 ½ teaspoons baking powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 2 large eggs
  • 1 cup whole milk
  • ½ cup vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup boiling water
  • 1 cup creamy peanut butter
  • 1 cup powdered sugar
  • ½ cup unsalted butter, softened
  • 1 teaspoon vanilla extract (for frosting)
  • 1 cup heavy cream
  • 1 cup chocolate chips (for ganache)

Preparing the Cake Batter

Let’s start by preheating the oven to 350°F (175°C). This is an essential step to ensure our cake bakes evenly. While the oven is heating up, I gather all my ingredients and get my baking pans ready. I like to use two 9-inch round cake pans for this recipe, so I grease them with a bit of butter and dust them with flour to prevent sticking.

  1. In a large mixing bowl, I combine the dry ingredients: 1 ¾ cups of all-purpose flour, 1 cup of granulated sugar, ½ cup of unsweetened cocoa powder, 1 ½ teaspoons of baking powder, 1 teaspoon of baking soda, and ½ teaspoon of salt. I whisk them together until they are well blended.
  2. Next, I add the wet ingredients to the dry mixture. I crack in 2 large eggs, pour in 1 cup of whole milk, add ½ cup of vegetable oil, and 2 teaspoons of vanilla extract. Using a hand mixer, I beat the mixture on medium speed for about 2 minutes until it’s smooth and well combined.
  3. Now, here’s the fun part! I carefully stir in 1 cup of boiling water. This step makes the batter thin, but it’s crucial for a moist cake. I mix it until everything is well incorporated.

Baking the Cake

With the batter ready, it’s time to pour it into the prepared pans.

  1. I divide the batter evenly between the two greased cake pans. I like to use a spatula to scrape down the sides of the bowl to ensure I get every last bit of that delicious batter.
  2. Now, I place the pans in the preheated oven and bake for 30-35 minutes. I check for doneness by inserting a toothpick into the center of the cakes; if it comes out clean, they’re ready!
  3. Once baked, I remove the cakes from the oven and let them cool in the pans for about 10 minutes. Then, I carefully turn them out onto a wire rack to cool completely. This is important because we don’t want to frost a warm cake!

Making the Peanut Butter Frosting

While the cakes are cooling, I prepare the peanut butter frosting. This frosting is rich and creamy, perfect for complementing the chocolate cake.

  1. In a mixing bowl, I combine 1 cup of creamy peanut butter, ½ cup of softened unsalted butter, and 1 cup of powdered sugar. I also add 1 teaspoon of vanilla extract for extra flavor.
  2. Using a hand mixer, I beat the mixture on medium speed until it’s smooth and creamy. If the frosting is too thick, I can add a tablespoon of milk at a time until I reach my desired consistency.

Assembling the Cake

Now that the cakes are cool and the frosting is ready, it’s time to assemble our masterpiece!

  1. I take one of the cooled cake layers and place it on a serving plate. I spread a generous layer of peanut butter frosting on top of it, making sure to cover it evenly.
  2. Next, I carefully place the second cake layer on top of the frosted layer. I gently press down to ensure it sticks.
  3. Now, I spread frosting over the top and the sides of the entire cake

Peanut Butter Cup Cake

Conclusion:

In summary, this Peanut Butter Cup Cake is an absolute must-try for anyone who loves the rich, creamy flavor of peanut butter combined with the sweetness of chocolate. The moist cake, paired with a luscious peanut butter frosting and topped with chocolate ganache, creates a dessert that is not only visually stunning but also incredibly delicious. Whether you’re celebrating a special occasion or simply indulging in a sweet treat, this cake is sure to impress your family and friends. For serving suggestions, consider pairing this delightful cake with a scoop of vanilla ice cream or a dollop of whipped cream to balance the richness. You can also experiment with variations by adding crushed peanuts on top for an extra crunch or incorporating a layer of chocolate chips within the cake batter for an added surprise. If you’re feeling adventurous, try swapping out the peanut butter for almond or cashew butter for a unique twist!
