Step‑by‑Step Instructions for Peanut Butter Cup Cookie Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (177°C). While the oven heats up, prepare your 9-inch springform pan by lightly coating it with non-stick spray. This will ensure your delicious Peanut Butter Cup Cookie Cake releases easily after baking, leaving you with a perfect presentation.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking soda, and salt until well combined. This step helps evenly distribute the leavening agent and seasoning throughout your dry mix. Set the bowl aside while you move on to the next step, ensuring a smooth blending process later.
Step 3: Cream the Wet Ingredients
In the bowl of a stand mixer, beat together the softened unsalted butter, creamy peanut butter, brown sugar, and granulated sugar on medium speed until the mixture becomes light and fluffy, taking about 3-4 minutes. Add the large egg and vanilla extract, mixing until fully incorporated. The wet ingredients are now ready to blend with the dry ones!
Step 4: Combine Mixtures
Gradually add the dry ingredients to the wet mixture, using a spatula or mixer on low speed. Mix just until combined to avoid overworking the batter. Once the flour disappears, gently fold in the miniature peanut butter cups, making sure they are evenly distributed throughout the dough for that delightful surprise in every bite.
Step 5: Bake the Cake
Spread the cookie dough evenly in your prepared springform pan. Place it in the preheated oven and bake for 20-25 minutes, or until the edges are lightly browned, and a toothpick inserted in the center comes out clean. Keep an eye on the cake as it bakes to ensure it doesn’t overbake, resulting in a dry texture.
Step 6: Cool the Cake
Once the Peanut Butter Cup Cookie Cake is done baking, remove it from the oven and let it cool in the pan for about 10 minutes. After that, carefully transfer the cake to a wire rack to cool completely. This step is crucial to avoid melting your frosting when you’re ready to decorate!
Step 7: Make the Frosting
While your cake cools, prepare the frosting. In a large bowl, beat the softened butter on high speed until smooth and creamy, which takes about 2 minutes. Gradually add powdered sugar, cocoa powder, and heavy cream. Mix until the icing is light and fluffy. Taste it to ensure it’s just the right sweetness for your Peanut Butter Cup Cookie Cake.
Step 8: Frost the Cake
Once the cake is completely cool, generously frost the top with your chocolate frosting, spreading it evenly with a spatula. Feel free to get creative with the design! You may sprinkle some extra mini peanut butter cups on top for an extra decadent touch that will impress your guests.

How to Store and Freeze Peanut Butter Cup Cookie Cake
Room Temperature: Store uneaten cake at room temperature in an airtight container for up to 4 days to maintain its soft, chewy texture.
Fridge: If you have frosting on the cake, cover it with plastic wrap and refrigerate to keep it fresh for up to a week; it may lose some moisture over time.
Freezer: Wrap the cooled cake tightly in plastic wrap and then in aluminum foil. Freeze for up to 3 months for the best quality. Thaw overnight in the refrigerator before serving.
Reheating: For a warm slice, gently reheat in the microwave for 10-15 seconds. Enjoy your delightful Peanut Butter Cup Cookie Cake!
