Chocolate Peanut Butter cupcakes

Step up your peanut butter cupcake game with these amazing cupcakes filled with Reese’s peanut butter cups!

Chocolate and peanut butter together make the best combo, in my opinion. I have made this peanut butter icing many times and it is always a hit. I tried something different with these cupcakes though and it made them even better!

There are many recipes out there on how to make chocolate cupcakes from scratch, and I have done it a few times, but I still say nothing can beat the out-of-the-box mix. They always turn out moist and it is so much easier to make. Start by mixing it and fill the cupcake liner halfway, you could fill it more but I learned my lesson the hard way. Bake them for 8 minutes. While those 8 minutes are counting down, start unwrapping some Reese’s cups. Line up and have them ready to go as best you can when the timer goes off. After 8 minutes, take the cupcakes out and place the Reeses right on top of the cupcakes and press down slightly. Place back into the oven and bake for the additional time – the sweet spot with my oven was another 12 minutes.

While the cupcakes are cooling, go ahead and get the stick of butter out to start softening for the icing.

When the cupcakes are cool, start whipping up the icing. Mix the butter, and peanut butter until smooth. Add half of the powdered sugar and mix slowly. Add half of the whipping cream, salt, and vanilla. Mix and slowly add the remaining powdered sugar. If the icing is too stiff add a little bit more whipping cream, and if it is too runny, add a bit more powdered sugar.

Ice the cupcakes however you please, and add half a Reese’s cup as garnish. Enjoy!


I have tried putting the Reese cup in the batter before baking at all, but they fall entirely to the bottom; which is why I think it is best to bake partly before adding them.

As I said above, there are many great made-from-scratch batter recipes, but I will always do the box mix from now on. It is just so much easier and still tastes great. If that doesn’t seem fancy enough, here are some things you can change to doctor it up.

You can add fuller than halfway, but this just causes them to bake over the top once you add the Reese’s cup, which is not as pretty.

You can add a variety of different garnishes other than Reese’s cups; such as peanuts, chocolate shavings, melted chocolate drizzle, etc., or add all!
