Step‑by‑Step Instructions for Peanut Butter Chocolate Cupcakes
Step 1: Preheat the Oven
Start by preheating your oven to 160ºC (320ºF). While the oven heats up, line a 12-cup muffin tray with cupcake liners, ensuring they sit neatly without folding over. This setup will keep your Peanut Butter Chocolate Cupcakes from sticking and help you achieve a lovely presentation when they’re baked.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine granulated sugar, unsweetened Dutch cocoa powder, all-purpose flour, instant espresso powder, baking powder, baking soda, and salt. Whisk these dry ingredients together until they’re fully combined, giving you a chocolatey blend that forms the base of your cupcakes. Aim for a uniform color and texture to ensure even baking.
Step 3: Combine the Wet Ingredients
Grab another bowl and whisk together the sour cream, vegetable oil, large eggs, vanilla extract, and boiling water. Continue mixing until the mixture is smooth and silky, with no lumps left behind. This step is crucial since it infuses moisture and richness into your Peanut Butter Chocolate Cupcakes, creating a delightful texture.
Step 4: Blend Wet and Dry Ingredients
Gently pour the wet ingredients into the dry ingredients, using a spatula to combine them. Stir slowly and softly until just incorporated, taking care not to overmix. Look for a batter that’s well-blended but slightly lumpy; this means your cupcakes will be tender and fluffy once baked.
Step 5: Bake the Cupcakes
Spoon the batter into the prepared cupcake liners, filling each about two-thirds full. Bake them in the preheated oven for 20-23 minutes or until they spring back gently when touched and a toothpick inserted into the center comes out clean. Allow the cupcakes to cool in the tray for 5 minutes before moving them to a wire rack to cool completely.
Step 6: Prepare the Frosting
In a stand mixer or using a hand mixer, beat together room temperature butter and creamy peanut butter until the mixture is light and fluffy, about 2-3 minutes. Gradually add in the powdered sugar, vanilla extract, and milk, mixing until everything is thoroughly combined and you achieve a spreadable, fluffy frosting consistency perfect for topping your Peanut Butter Chocolate Cupcakes.
Step 7: Core the Cupcakes
Once your cupcakes have completely cooled, take a piping tip or a sharp knife to hollow out a small section from the center of each cupcake. This creates space for the creamy peanut butter filling that will give your cupcakes an indulgent surprise when bitten into.
Step 8: Fill and Frost the Cupcakes
Using a piping bag, fill the hollow centers of the cupcakes with creamy peanut butter. Then, generously pipe your delicious peanut butter frosting on top of each cupcake, creating a beautiful swirl. Finally, for an extra touch of flavor and crunch, sprinkle chopped peanuts and add mini Reese’s peanut butter cups on top for decoration.

Expert Tips for Peanut Butter Chocolate Cupcakes

Room Temperature Eggs: Make sure your eggs are at room temperature for better mixing, which leads to a fluffier cupcake.
-
Sift the Sugar: Sifting powdered sugar before adding to the frosting helps avoid lumps, ensuring a smooth and creamy peanut butter frosting.
-
Cool Completely: Allow both the cupcakes and frosting to cool completely before frosting. This prevents melting and achieves the best texture.

Don’t Overmix: When combining wet and dry ingredients, stir gently to avoid overmixing. This keeps your Peanut Butter Chocolate Cupcakes soft and fluffy.
Make Ahead Options
These Peanut Butter Chocolate Cupcakes are a fantastic choice for meal prep enthusiasts looking to save time during busy weeks! You can prepare the cupcake batter up to 24 hours in advance—simply mix the wet and dry ingredients as directed, but refrigerate it instead of baking. You can also bake the cupcakes and store them in an airtight container for up to 3 days at room temperature, ensuring they remain moist. For the frosting, make it ahead and refrigerate it for up to 3 days; just give it a quick whip before piping. When you’re ready to enjoy, simply core the cooled cupcakes, fill with creamy peanut butter, frost, and decorate to have delicious treats that taste just as fresh as the day they were made!
How to Store and Freeze Peanut Butter Chocolate Cupcakes

Peanut Butter Chocolate Cupcakes Recipe FAQs
What type of peanut butter should I use for these cupcakes?
I recommend using creamy peanut butter for both the filling and the frosting. This gives you that smooth texture that’s easy to spread and pipe. If you prefer a chunky version, just be aware it will change the texture a bit, adding more crunch to your cupcakes.
How do I store leftovers to keep them fresh?
To maintain their freshness, store your Peanut Butter Chocolate Cupcakes in an airtight container at room temperature for up to 2 days. For longer storage, place them in the fridge where they can last up to 3 days. This helps prevent them from drying out and keeps them deliciously moist.
Can I freeze these cupcakes?
Absolutely! To freeze your cupcakes, wrap each one individually in plastic wrap and place them in a freezer-safe container or bag. They’ll stay fresh for up to 3 months. When you’re ready to enjoy, thaw them in the fridge overnight, then let them sit at room temperature for about 30 minutes before serving.
What should I do if my cupcakes are too dry?
If you find your Peanut Butter Chocolate Cupcakes turned out a bit dry, consider testing them next time with a higher moisture content—like adding a bit more sour cream or oil to the mixture. Also, make sure not to overbake them; baking for too long can really dry them out. A cake tester should come out clean, but if the top springs back when pressed lightly, they’re done!
Are there nut allergy concerns with this recipe?
Yes, since this recipe contains peanut butter, it’s not suitable for those with nut allergies. If you’re looking for alternatives, consider using sun butter or a seed butter, which can provide a similar flavor without the nuts. Just make sure to check that any other ingredients, like chocolate or frosting, are also allergy-friendly!
Can I make these cupcakes gluten-free?
Certainly! Simply substitute the all-purpose flour with a 1:1 gluten-free flour blend. This helps maintain the cupcake’s texture while making them suitable for those with gluten sensitivities. Just remember to ensure your baking powder and any other ingredients are certified gluten-free!
