Gather the ingredients for these chocolate peanut butter cupcakes

To get started on making these delicious chocolate peanut butter cupcakes, first gather all of your ingredients. Ensuring you have everything on hand will make the baking process run so much smoother!

For the chocolate cupcakes, you'll need a quarter cup of white sugar, a half cup of brown sugar, three-quarters of a cup of flour, half a cup of cocoa powder, three-quarters of a teaspoon of baking powder, three-quarters of a teaspoon of baking soda, half a teaspoon of salt, one egg, half a cup of milk, and a quarter cup of oil.

For the peanut butter frosting to go on top of your cupcakes, you'll need one stick of unsalted butter, softened, five to six cups of powdered sugar, two tablespoons of milk, and four tablespoons of creamy peanut butter.

Mix the dry ingredients to start the chocolate cupcake batter

To get started on making a batch of chocolate peanut butter cupcakes on your own at home, first turn on the oven. Preheat the oven to 350 degrees Fahrenheit so it's up to the right temperature by the time your cupcake batter is ready.

In a large mixing, add all of the dry ingredients. Add the white sugar, brown sugar, flour, baking powder, baking soda, and salt. Mix the dry ingredients using a hand mixer, or utilize a stand mixer fitted with the paddle attachment.

Mix the dry ingredients until well incorporated and free of any large clumps before moving onto the next step.

Add the wet ingredients to finish the chocolate cupcake batter

To finish the chocolate cupcake batter, add all of the wet ingredients into the dry ingredient mixture. First, mix in the egg. Then, mix in the oil, continue mixing, and then add in the milk. Mix the batter until just incorporated. Just be sure not to over-mix at this step.

Once the chocolate cupcake batter is ready, prepare a cupcake pan with paper liners to prevent the cupcakes from sticking while baking. If you don't have paper liners, utilize cooking spray.

Fill each cupcake pan well half-way full with the batter. Then, place the pan in the oven and bake the cupcakes for 18 to 20 minutes until the tops are set. Once the cupcakes are finished baking, remove them from the oven and set aside to fully cool.

Make the peanut butter frosting for these chocolate peanut butter cupcakes

While the chocolate peanut butter cupcakes cool, make the peanut butter frosting to pair with them. Add the softened stick of butter into a mixing bowl. Mix with a hand mixer to break it up until light and fluffy. Next, add in two cups of powdered sugar, and mix in the sugar with the butter. Then, mix in two tablespoons of milk. Continue to gradually add the rest of the powdered sugar as you mix, allowing the frosting to thicken. Once the frosting comes together, mix in the four tablespoons of peanut butter, and then turn the speed up on the mixer to whip the frosting until fluffy.

Decorate these chocolate peanut butter cupcakes

Once the chocolate peanut butter cupcakes have fully cooled, top each cupcake with peanut butter frosting. To decorate the cupcakes, first drizzle the tops with melted peanut butter. To do this, put a spoonful of peanut butter into a plastic piping bag, and microwave it for 30 seconds. Then, make a small cut at the end and drizzle the liquid over the frosting. Alternatively, you can certainly melt the peanut butter in a small bowl and then drizzle it with a fork. 

Lastly, sprinkle the cupcakes with crushed Reese's Pieces and add a wedge of a Reese's peanut butter cup on top, if desired.
