Step‑by‑Step Instructions for Peanut Butter Chocolate Cupcakes
Step 1: Preheat the Oven
Begin by preheating your oven to 160ºC (320ºF). While it warms up, prepare a 12-cup cupcake tin by lining it with paper liners. This is essential for preventing the cupcakes from sticking and helps with easy serving later on.
Step 2: Prepare the Dry Ingredients
In a large mixing bowl, sift together the all-purpose flour, unsweetened Dutch cocoa powder, granulated sugar, baking powder, baking soda, salt, and instant espresso powder. Whisk these dry ingredients until they are well combined; this will ensure an even chocolate flavor throughout your Peanut Butter Chocolate Cupcakes.
Step 3: Combine the Wet Ingredients
In a separate bowl, whisk together the wet ingredients: the large eggs, sour cream, vegetable oil, vanilla extract, and the boiling water. Make sure the water is hot for the best results. The mixture should be smooth and well-blended, with a rich aroma of chocolate wafting up to greet you.
Step 4: Combine Mixtures
Carefully pour the wet ingredients into the bowl of dry ingredients. Using a rubber spatula or wooden spoon, gently mix until everything is just combined—avoid over-mixing, as this could lead to dense cupcakes. The batter should be smooth and a bit glossy, indicating it’s ready for baking.
Step 5: Bake the Cupcakes
Evenly distribute the batter among the prepared cupcake liners until they are about two-thirds full. Place the cupcake tin in the preheated oven and bake for 20-23 minutes. To check for doneness, insert a toothpick into the center; it should come out clean or with a few moist crumbs clinging to it.
Step 6: Cool the Cupcakes
Once baked, remove the cupcake tin from the oven and let it cool in the pan for about 5-10 minutes. Then, gently transfer the cupcakes to a wire rack to cool completely. This step is crucial, allowing your Peanut Butter Chocolate Cupcakes to set perfectly before frosting.
Step 7: Make the Peanut Butter Frosting
In a mixing bowl, beat together the room-temperature butter and creamy peanut butter until smooth and creamy. Gradually add the powdered sugar and milk, mixing until the frosting reaches a fluffy consistency. Taste and adjust with more sugar or milk as necessary for the perfect spreadable texture.
Step 8: Fill the Cupcakes
For a delicious surprise, use a small knife or cupcake corer to remove a portion from the center of each cooled cupcake. Fill the hollow with a generous spoonful of creamy peanut butter, allowing the rich flavor to seep into the cake.
Step 9: Decorate the Cupcakes
Now it’s time for the fun part! Using a piping bag, pipe the peanut butter frosting generously on top of each cupcake, creating a beautiful swirl. Finish by garnishing with mini Reese’s Peanut Butter Cups and a sprinkle of chopped peanuts for that extra crunch and flavor.

Storage Tips for Peanut Butter Chocolate Cupcakes

- Fridge: Once frosted, store your Peanut Butter Chocolate Cupcakes in the fridge for up to a week. However, they are best enjoyed within 1-2 days of frosting for optimal flavor and freshness.
- Freezer: For longer storage, freeze unfrosted cupcakes by wrapping them tightly in plastic wrap and then placing them in an airtight container. They can last up to 3 months.
- Reheating: To enjoy cupcakes warm, thaw and then microwave for about 10-15 seconds. This restores the delightful softness of the cake.

Peanut Butter Chocolate Cupcakes Recipe FAQs
What type of peanut butter should I use for the frosting?
I recommend using creamy natural peanut butter for a healthier option and a smooth texture. If you prefer some crunch, feel free to swap it for crunchy peanut butter, which adds delightful texture to your cupcakes.
How should I store leftover cupcakes?
Unfrosted Peanut Butter Chocolate Cupcakes can be stored at room temperature in an airtight container for 1-2 days. For frosted cupcakes, keep them in the fridge for up to a week but try to enjoy them within 1-2 days after frosting for the best flavor.
Can I freeze these cupcakes?
Absolutely! To freeze your Peanut Butter Chocolate Cupcakes, allow them to cool completely, then wrap each unfrosted cupcake tightly in plastic wrap. Place them in an airtight container or zip-top freezer bag. They can be frozen for up to 3 months. When you’re ready to enjoy them, thaw at room temperature or microwave for about 10-15 seconds.
What should I do if my cupcakes come out dense?
If your cupcakes turn out dense, it could be due to over-mixing the batter once the wet and dry ingredients are combined. Make sure to mix just until combined for a light texture. Also, ensure your baking powder and baking soda are fresh, as old leavening agents can affect the rise.
Are these cupcakes suitable for people with allergies?
These Peanut Butter Chocolate Cupcakes are not gluten-free or nut-free, so if you have allergies, be cautious. You can use a gluten-free flour blend to make them gluten-free, and for nut-free options, substituting with seed butter like sunflower seed butter works well; just keep in mind that flavor will vary.
Can I use a different frosting option?
Certainly! If you’re looking to mix things up, you can experiment with chocolate ganache or cream cheese icing. Both will offer a unique twist on your cupcakes while still complementing that rich chocolate and peanut butter flavor.
