Essential Ingredients for a Peanut Butter Cup Cake

This show-stopping birthday cake comes together with three delicious components.

• For the Moist Peanut Butter Cake:
  • 2 ½ cups of all-purpose flour
  • 1 ½ cups of packed light brown sugar
  • 1 cup (2 sticks) of unsalted butter, softened
  • 1 cup of creamy peanut butter
  • 4 large eggs, at room temperature
  • 1 cup of buttermilk, at room temperature
  • 1 tablespoon of baking powder
• For the Peanut Butter Buttercream:
  • 1 cup (2 sticks) of unsalted butter, softened
  • 1 ½ cups of creamy peanut butter
  • 4 cups of powdered sugar
  • ½ cup of heavy cream
• For the Chocolate Ganache Drip & Garnish:
  • 8 oz (225g) of semi-sweet chocolate, chopped
  • ¾ cup of heavy cream
  • 1 ½ cups of mini peanut butter cups, chopped

Ingredients Notes

A little more detail on our key ingredients will ensure your drip cake is a spectacular success.

• The Peanut Butter: For the best and most consistent results in both the cake and the frosting, it is highly recommended to use a standard, commercial-style creamy peanut butter, not a natural, oil-on-top variety. The emulsifiers in the commercial peanut butter help to create a stable and perfect texture.
• The Buttermilk: The buttermilk provides a slight, pleasant tang that beautifully cuts through the richness of the peanut butter. It also reacts with the baking powder to create an incredibly soft and tender cake crumb.
• The Peanut Butter Cups: This is the star garnish! Using mini peanut butter cups is a great choice as they are the perfect size for piling on top of the cake and for folding into the filling.
• The Room Temperature Ingredients: For the smoothest cake batter and buttercream frosting, it is absolutely essential that your butter, eggs, and buttermilk are all at room temperature before you begin mixing.

How to Make a Gourmet Creation

Let’s walk through the incredibly simple steps to create this perfect, impressive dessert.

• Step 1: Make the Cake Layers. Preheat your oven to 175°C (350°F) and prepare three 8-inch round cake pans. Cream the butter, peanut butter, and brown sugar together until light and fluffy. Beat in the eggs, then alternately add the dry ingredients and the buttermilk, mixing until just combined.
• Step 2: Bake and Cool. Divide the batter evenly among your three prepared cake pans and bake for 30-35 minutes. Let the cake layers cool completely in the pans before turning them out onto a wire rack.
• Step 3: Make the Peanut Butter Buttercream. While the cakes are cooling, beat the softened butter and the peanut butter together until creamy. Gradually add the powdered sugar, alternating with the heavy cream, until you have a light and fluffy buttercream.
• Step 4: Assemble the Cake. Place one completely cooled cake layer on your serving plate. Frost the top, then sprinkle with a generous layer of chopped peanut butter cups. Repeat with the second layer, then place the final layer on top and apply a thin “crumb coat” of frosting all over the cake. Chill the cake in the refrigerator for at least 30 minutes.
• Step 5: Make the Ganache and Decorate. Apply a final, smooth layer of the peanut butter buttercream over the entire cake. To make the ganache, heat the heavy cream until just simmering and pour it over the chopped chocolate, letting it sit for 5 minutes before stirring until smooth. Let the ganache cool slightly, then pour it over the top of your chilled cake, allowing it to drip down the sides.
• Step 6: The Final Touch. Pile the remaining chopped peanut butter cups in the center of the cake. Chill the cake for another 15 minutes to set the drip.

Storage Options

This beautiful peanut butter cup cake is a fantastic make-ahead dessert for any party. You can store the finished cake in an airtight cake carrier in the refrigerator for up to 5 days. For the best taste and texture, it is a great idea to let the cake sit at room temperature for about 30 minutes before you serve it.

Variations and Substitutions

This classic recipe is a wonderful and versatile template. For a Gluten-Free version, you can substitute the all-purpose flour with a high-quality, 1-to-1 gluten-free baking blend that contains xanthan gum, such as one made with Almond Flour. For a Dairy-Free or Vegan version, you would need to use a stick-style vegan butter, a plant-based Nut Milk to create a vegan “buttermilk,” and a vegan buttercream and ganache recipe. For a High Protein twist, you could even add a scoop of your favorite vanilla or chocolate Protein Powder to the buttercream frosting.

Practical & Valuable Tips

For the most tender cake crumb, be sure that your butter, eggs, and buttermilk are all at room temperature. The most important tip for a perfect drip is to apply it to a very cold, well-chilled cake. Finally, a great trick for getting perfectly chopped peanut butter cups for your garnish is to chill them in the freezer for a few minutes before you chop them, or to give them a quick pulse in a Blender or Food Processor.

Frequently Asked Questions

1. Can I make this cake ahead of time? Yes, this is the perfect make-ahead cake! You can bake the cake layers up to two days in advance and store them, well-wrapped, at room temperature. You can then assemble and decorate the cake a day before your party.
2. My ganache is too thick/thin. What did I do wrong? If your ganache is too thick, you can simply whisk in another tablespoon of warm heavy cream until it reaches the right consistency. If it is too thin, it is likely too warm; just let it cool down for a few more minutes at room temperature to thicken up slightly before you pour it.
3. My cake is a little dry. What did I do wrong? A dry cake is almost always a result of it being slightly overbaked. It is very important to check the cake with a toothpick and pull it from the oven as soon as the toothpick comes out clean or with a few moist crumbs attached.
4. Can I use a different kind of candy? Of course! While peanut butter cups are the classic choice, this cake would be absolutely delicious with other chopped chocolate and peanut butter candies, or even with some chopped Snickers or Butterfinger bars.
5. Can I make this in a different sized pan? Yes, you can easily adapt this recipe for a 9×13 inch sheet cake. You would just need to increase the baking time by about 5 to 10 minutes, and you would simply spread the frosting and ganache over the top.
