About Mint Chocolate Cupcakes

Whether you’re craving the combination of mint and chocolate flavors (who isn’t?!) or are searching for an eye-catching dessert for St Patrick’s Day, these homemade mint chocolate cupcakes are ready to be the favorite food of the evening.

And really, how much more perfect could these cupcakes be? They bake up soft and moist (with a delightful mint and chocolate flavor) and the buttercream is bright, festive, and fluffy.

These cupcakes are sure to be a go-to for decadent mint chocolate goodness.

What’s in mint chocolate cupcakes?

To make a big batch of these minty chocolatey cupcakes, you’ll need to gather the following ingredients:

  • All-purpose flour, salted butter, baking powder, granulated sugar, powdered sugar, milk, and eggs – Classic ingredients for baked goods and homemade frosting.
  • Unsweetened cocoa powder – For adding that delicious chocolate flavor. While this recipe recommends unsweetened cocoa powder, you can substitute it for an equal portion of dark or Dutch-processed cocoa powder instead. No matter which type of cocoa powder you use, there shouldn’t be a dramatic change in taste, texture or color with the finished cupcakes.
  • Peppermint extract and mint leaves – Used for flavoring the cupcakes with mint and garnishing the frosting.
  • Green food coloring – Totally optional, but gives these cupcakes a fun mint-themed hue. Teal or blue food coloring would also be a good fit.

What’s the difference between mint and peppermint?

These cupcakes are called mint chocolate, but the recipe itself uses peppermint extract.

So, you might be wondering, what gives? Why are there different names? What is the difference between mint and peppermint?

Well, to keep it short and sweet, mint is the overall name of the mint plant family. There are many different members within this family (ie different types of mint plants) with spearmint and peppermint being the two most popular. Spearmint has a sweeter flavor while peppermint is sharper and more potent. And since mint is meant to encompass the whole flavor profile, it has qualities of both spearmint and peppermint.

As far as baking, you can substitute any mint extract in place of another one, since you’ll still have a minty flavor – it just depends on how intense you want that flavor to be. Peppermint would be the strongest, followed by mint, and spearmint would be the sweetest.

How should these cupcakes be stored?

The cupcakes can be stored in an airtight container on the counter or in the refrigerator. The frosting is shelf-stable and can safely be stored without chilling.

How long will mint chocolate cupcakes last?

When stored in a sealed container on the counter, cupcakes can last anywhere from three to five days. When stored in the refrigerator, they could last up to a week.

Can you freeze mint chocolate cupcakes?

Yes, you totally can!

To freeze these cupcakes:

  • Bake cupcakes per recipe instructions, then allow to cool completely. Note: for best and consistent results, do not decorate cupcakes before freezing. Frosting types and consistency may vary and could impact how long or well the cupcakes will last while frozen.
  • Wrap cupcakes in plastic wrap. You can either wrap them individually or arrange the cupcakes in a group (single layer) and wrap them together.
  • Place wrapped cupcakes in a freezer bag or a storage container with a sealable lid.
  • Cupcakes can be frozen for up to three months.

Can these cupcakes be made in advance?

Yes, they totally can!

Unbaked: You can whip up the batter and store it in a sealed container in the refrigerator for up to 48 hours.

Baked: To ensure the best presentation, I would recommend making them up to 24 hours in advance.

Notes & tips for mint chocolate cupcakes

  • This recipe has only been tested with whole milk, so I can’t recommend any substitutions (almond, oat, etc).
  • Feel free to add up to 1/2 cup of semi-sweet chocolate chips or crumbled Andes Mints candy to take these cupcakes to the next minty chocolaty level.
