These Mint Chocolate Chip Cupcakes start with the best chocolate cupcakes flavored with a hint of mint and topped with fluffy mint buttercream frosting loaded with tiny pieces of dark chocolate. If mint chocolate chip ice cream is your thing, this cupcake version delivers the same cool mint and chocolate combination in cake form.

Mint and chocolate is one of those flavor combinations that people tend to feel strongly about. You either love it, or you really don’t.

I’ve always been firmly in the love it camp.

So when I was planning this year’s Cupcake of the Month for March, mint chocolate chip felt like the obvious choice. It’s fresh, a little nostalgic, and just the right flavor combination to bridge winter chocolate desserts and the lighter flavors of spring.

These cupcakes start with a soft chocolate base with just a hint of mint in the batter. On top is a fluffy mint buttercream that is packed with finely chopped dark chocolate, giving it that classic mint chocolate chip look with little bursts of chocolate in every bite.

The result tastes a lot like mint chocolate chip ice cream… just in cupcake form.

Key Ingredients and Substitutions

Mint chocolate chip cupcakes sound a little fancy, but the ingredients are actually very straightforward. A classic chocolate cupcake base provides the foundation, and the mint chocolate chip flavor comes together in the frosting.

All-Purpose Flour

Use regular all-purpose flour for the best cupcake structure and texture. To make these cupcakes gluten free, substitute a 1:1 gluten-free baking flour blend designed for baking, such as King Arthur or Bob’s Red Mill.

Cocoa Powder

Use natural unsweetened cocoa powder, not Dutch-process cocoa. The baking soda in the recipe relies on the acidity of natural cocoa powder to help the cupcakes rise properly.

Buttermilk

Buttermilk helps keep the cupcakes soft and tender. If you don’t have buttermilk, stir 2 teaspoons vinegar or lemon juice into ¾ cup milk and let it sit for about 5 minutes before using.

Mint Extract

Mint extract flavors both the cupcakes and the frosting. It can be strong, so start with the amount listed—just a little gives the cupcakes that classic cool mint flavor.

Dark Chocolate

Finely chopped dark chocolate gets folded into the frosting to create the classic mint chocolate chip texture. Mini chocolate chips work well here, too.

Green Gel Food Coloring

A drop or two gives the frosting that classic minty green color. Gel food coloring works best because it adds color without thinning the frosting.

Buttermilk for Extra Tender Chocolate Cupcakes

Chocolate cupcakes can easily turn out dense or slightly dry, especially since cocoa powder is involved. Cocoa naturally absorbs a lot of liquid, which means recipes need something to keep the crumb soft and light.

That’s where buttermilk helps. Buttermilk adds both moisture and acidity to the batter, improving the final texture of the cupcakes.

Kitchen Chemistry

The acid in buttermilk reacts with baking soda in the batter to produce carbon dioxide gas, helping the cupcakes rise, while also weakening gluten formation to keep the crumb tender.

The result is a cupcake that bakes up soft and light instead of tight or dense. Deliciousness through chemistry!

How to Make Mint Chocolate Chip Cupcakes

These cupcakes come together quickly with a simple whisk-by-hand chocolate batter and a classic minty buttercream frosting.

Whisk the Dry Ingredients

Start by whisking together the flour, sugar, cocoa powder, baking soda, baking powder, and salt in a large bowl. Cocoa powder tends to clump, so take a moment to break up any small lumps while you’re mixing.

Combine the Wet Ingredients

In a second bowl, whisk together the egg, buttermilk, oil, vanilla extract, and mint extract. The mixture should look smooth and slightly glossy once everything is combined.

Make the Chocolate Cupcake Batter

Pour the wet ingredients into the bowl with the dry ingredients and whisk until the batter is smooth and fully combined. The cupcake batter will be thin, which is exactly what you want for soft chocolate cupcakes.

Bake the Cupcakes

Divide the batter among the cupcake liners, filling each slightly over halfway. This gives the cupcakes enough room to rise without spilling over the edges of the pan.

Bake the cupcakes until the tops spring back lightly when pressed and a toothpick inserted into the center comes out with a few moist crumbs.

Make the Mint Chocolate Chip Frosting

While the cupcakes cool, beat the butter until light and fluffy, then gradually add the powderd sugar and heavy cream. Once the frosting is smooth, mix in the mint extract and a drop or two of green food coloring.

Fold in the chopped dark chocolate at the end so the little chocolate pieces stay evenly distributed.

Frost the Cupcakes

Once the cupcakes are completely cool, pipe or spread the frosting on top. Finish with chocolate shavings or mini chocolate chips if you want to lean even further into that classic mint chocolate chip look.

If you love mint chocolate chip ice cream, these cupcakes will feel very familiar, in the best possible way!
