Equipment you’ll need

Ingredients

Below is a list of the ingredients you’ll need to gather to make this recipe, why you need them, and possible substitutions. Scroll all the way down for the full recipe card with measurements.

For the Dark Chocolate Cupcakes:

  • Butter Use room-temperature unsalted butter, cubed, to control the amount of salt. If you’ve only got salted butter on hand use it but omit any added salt.
  • Bittersweet ChocolateFinely chopped bittersweet chocolate adds more depth to the chocolate flavor. I like to use Ghirardelli baking chips because I always have them in the pantry or a bar of good baking chocolate.
  • Dutch-Processed CocoaI use Hershey’s Special Dark cocoa powder. Regular unsweetened cocoa powder will also work.
  • All-Purpose Flour Measure the flour correctly to avoid dry, dense cupcakes. Use a scale or the spoon and level method for just the right amount.
  • Baking Soda Baking soda helps the cupcakes rise. 
  • Baking PowderHelps give these cupcakes their light and fluffy texture. 
  • EggsI used large eggs at room temperature to bind the cupcakes and keep them nice and moist. Starting with room temperature ingredients helps with even baking.
  • White SugarSugar sweetens up these cupcakes, as bittersweet chocolate is, well, bitter.
  • Vanilla ExtractUse real vanilla extract for the best flavor.
  • SaltA touch of salt enhances the flavor.
  • Greek YogurtUse plain Greek yogurt, any fat content will work. 
  • Reese’s Peanut Butter Cups  – These full-sized peanut butter cups go inside each of the cupcakes for a fun little surprise!

For the Peanut Butter Frosting:

  • Butter – Use unsalted butter at room temperature for the frosting. It needs to be able to whip and cream nicely.
  • Peanut ButterI prefer to use commercial peanut butter as it will hold the structure better than natural peanut butter, which is runnier and has a tendency to separate. However, because commercial peanut butter usually contains sugar, your frosting may be on the sweeter side. Use natural peanut butter or one that is unsweetened if you’d like to try it out.
  • Powdered SugarAlso known as confectioners’ sugar this is what gives the frosting its sweet taste and silky texture. 
  • Heavy CreamHeavy cream adds richness and helps make the frosting spreadable but whole milk is another option. 
  • Mini Peanut Butter Cups – I used mini peanut butter cups for the tops of the cupcakes.

Tips & Suggestions

  • In place of bittersweet chocolate, you can use 1/4 cup of a dark chocolate chip (like Ghirardelli 60% baking chips) or semi-sweet chocolate chips will also work.
  • Try sour cream instead of Greek yogurt, full fat or low-fat are both good options.
  • For a super quick and easy alternative, use a chocolate cake mix instead of preparing the chocolate cupcake batter.
  • Substitute your favorite chocolate cupcake recipe and follow these instructions for adding the Reese’s cup and peanut butter frosting. 
  • Stir in a touch of espresso powder for a deeper chocolate flavor. Instant espresso is the best option.
