I’m excited to share this mint chocolate cupcake recipe. If you enjoy Andes mints, Thin Mint cookies, mint Aero bars, or mint chip ice cream, these chocolate cupcakes with mint frosting will hit the spot.
The cupcakes are tender and fudgy thanks to a batter made with oil, a single egg, and milk. Using oil keeps the crumb moist at room temperature because oil remains liquid, yet the chocolate flavor masks any trace of oil. Cocoa powder delivers the chocolate base, and a splash of freshly brewed coffee—or boiling water if you prefer—intensifies and deepens the cocoa, producing a richer, more robust chocolate taste.
The cupcakes are finished with a thick, silky mint buttercream that tastes like mint chip ice cream or a classic shamrock shake. The frosting is made from butter, sifted powdered sugar, a pinch of salt, whipping cream (or heavy cream), and mint extract, with a few drops of green food coloring if you want that classic mint color. I recommend whipping cream over milk for a creamier, more stable frosting.
Baking Tips & Tricks
- Bring the egg and milk to room temperature before starting so the batter mixes evenly.
- Sift cocoa powder to remove lumps—this ensures a smooth batter.
- You won’t taste the coffee; it just enhances the chocolate. If you prefer, use boiling water instead of brewed coffee.
- Mint extract is usually located near vanilla extract in the baking aisle.
- For fluffy, stable frosting, use butter that is softened but not greasy or melting.

Fudgy, moist, and crowned with luxuriously creamy frosting, these mint chocolate cupcakes are perfect for anyone who loves mint and chocolate together.

Ingredients
Chocolate Cupcakes
- 1 cup all-purpose flour (125 g), spooned and leveled
- 1 cup granulated sugar (200 g)
- 1/2 cup cocoa powder (45 g), Dutch-processed recommended
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/4 cup vegetable oil (60 ml)
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 1/2 cup milk (120 ml), 2% or whole
- 1/3 cup freshly brewed coffee (80 ml), or boiling water
Mint Buttercream
- 1 cups unsalted butter (226 g), slightly softened
- 3-4 cups powdered sugar (330–400 g), sifted
- 1/4 teaspoon salt, to taste
- 2-3 tablespoons whipping cream, or heavy cream
- 1/2-2 teaspoons mint extract
- green food coloring
- chocolate shavings or mini chocolate chips, for decorating, optional
Instructions
Chocolate Cupcakes
-
Preheat the oven to 350°F (180°C). Line a 12-cavity muffin tin with liners.
-
Whisk the dry ingredients—flour, cocoa, sugar, baking powder, baking soda, and salt—in a large bowl. Sift the cocoa powder to remove lumps, then set the mixture aside.
-
In a separate bowl, whisk together the oil, egg, milk, and vanilla.
-
Make a well in the dry ingredients, pour in the wet ingredients, and whisk until almost combined.
-
Whisk in the freshly brewed coffee (or boiling water) until the batter is smooth and glossy; it should be fairly thin.
-
Spoon batter into the prepared pan, filling each cup about two-thirds full. You should have 12–13 cupcakes. Bake 18–20 minutes, or until a toothpick comes out clean. Cool in the pan for 10 minutes, then transfer to a wire rack to finish cooling.
Mint Frosting
-
Beat the butter on medium speed until lightened and soft.
-
Add 2 cups sifted powdered sugar, salt, and 1/2 teaspoon mint extract. Start on low speed, then increase to medium and combine.
-
Beat in the remaining powdered sugar 1/2 cup at a time, alternating with 1 tablespoon whipping cream. Adjust mint extract to taste. For firmer frosting, use less cream and more powdered sugar. Optionally add a few drops of green food coloring.
-
Ensure cupcakes are completely cool before frosting. Pipe or spread the buttercream—use a 1M tip for a classic swirled look—and finish with chocolate shavings or mini chips if desired.
Notes
- Cocoa: The recipe was developed with Dutch-processed cocoa. Be sure to sift before measuring.
- Room Temperature: Allow the egg and milk to come to room temperature for best mixing and texture.
- Frosting Yield: If you prefer a thin spread of frosting, you can halve the frosting recipe.
- Nutrition: Nutrition facts are estimates based on one cupcake with frosting and assuming 12 equal cupcakes.
- Storage & Make-Ahead: Unfrosted cupcakes can be baked a day ahead, cooled completely, and stored in an airtight container. Prepare frosting the next day. Leftovers keep at room temperature up to 8 hours or refrigerated up to 4 days; bring to room temperature for about 30 minutes before serving.
