Step-by-Step Instructions for Peanut Butter Chocolate Cupcakes
Step 1: Preheat and Prepare
Begin by preheating your oven to 160ºC (320ºF) and lining a 12-cup cupcake pan with colorful liners. This ensures even baking and easy removal once the cupcakes are done. Gather your mixing bowls, measuring cups, and a whisk to get started on creating these delightful Peanut Butter Chocolate Cupcakes.
Step 2: Mix Dry Ingredients
In a large mixing bowl, whisk together the granulated sugar, unsweetened Dutch cocoa powder, all-purpose flour, espresso powder, baking powder, baking soda, and salt. This blend of dry ingredients will form the foundation of your cupcake batter. Make sure they’re well combined, as this aids in achieving a uniform texture in your delicious cupcakes.
Step 3: Combine Wet Ingredients
In a separate bowl, whisk together the sour cream, vegetable oil, large eggs, and vanilla extract until smooth. Once mixed, carefully pour in the cooled boiling water, mixing until everything is well incorporated. The combination of these wet ingredients adds moisture and richness to your Peanut Butter Chocolate Cupcakes, creating a tender crumb.
Step 4: Blend Wet and Dry Mixtures
Gradually pour the wet mixture into the bowl containing the dry ingredients. Stir with a spatula or a whisk until the batter is smooth and well-blended, but be careful not to overmix. The key to tender cupcakes is a light hand! Once your batter is ready, evenly distribute it among the prepared cupcake liners, filling each about two-thirds full.
Step 5: Bake to Perfection
Place the cupcake pan in the preheated oven and bake for 20-23 minutes, or until a toothpick inserted into the center comes out clean. Keep an eye on them as they bake—the cupcakes should rise beautifully and form a slight dome. Once done, remove them from the oven, and let them cool in the pan for about 5 minutes before transferring to a wire rack to cool completely.
Step 6: Prepare the Peanut Butter Buttercream
While the cupcakes cool, prepare your peanut butter buttercream. In a mixing bowl, beat together the softened butter and creamy peanut butter until the mixture is fluffy and smooth. Gradually add the sifted powdered sugar and a splash of milk, mixing well after each addition until you achieve a delightful consistency ready for frosting.
Step 7: Fill and Frost
Once the cupcakes are completely cooled, use a small knife or a cupcake corer to hollow out the center of each cupcake. Fill the cavity with a generous dollop of creamy peanut butter, allowing a little to spill over for extra indulgence. Then, generously frost the tops with your peanut butter buttercream, creating beautiful swirls.
Step 8: Decorate and Serve
Finally, for a fun and tasty finish, decorate the tops of your cupcakes with mini Reese’s Peanut Butter Cups and a sprinkle of chopped peanuts if desired. These little touches add flavor and crunch, making your Peanut Butter Chocolate Cupcakes not just delicious but stunning too. Enjoy these treats fresh or share them for a special occasion!

Peanut Butter Chocolate Cupcakes Recipe FAQs
What kind of peanut butter should I use for the filling?
I recommend using a creamy peanut butter for the filling, as it creates a smooth, luxurious texture that complements the chocolate. Avoid natural peanut butters that may contain oil separation; you want it to blend easily with the cupcakes.
How should I store leftover Peanut Butter Chocolate Cupcakes?
Unfrosted cupcakes can be stored at room temperature for up to 2 days in an airtight container. If they’ve been frosted, it’s best to keep them in the refrigerator for optimal freshness, and they should be consumed within 1-2 days.
Can I freeze Peanut Butter Chocolate Cupcakes?
Absolutely! For freezing, place unfrosted cupcakes on a baking sheet in a single layer and freeze until solid. Then, transfer them to a freezer-safe container or bag and store them for up to 3 months. Thaw them at room temperature before frosting and serving.
How can I avoid dry cupcakes?
To ensure your cupcakes are moist and tender, make sure to use room temperature ingredients, especially the sour cream and eggs. Mixing should be done lightly; overmixing can lead to a denser texture. Additionally, verifying that your leavening agents (baking powder and soda) are fresh is key to achieving that fluffy rise.
Is this recipe suitable for people with nut allergies?
This recipe contains peanut butter, so it’s not suitable for anyone with peanut allergies. However, for those looking for a nut-free alternative, sunflower seed butter can be a great option in place of peanut butter, keeping the flavors enjoyable without the nut content.
