Instructions
- 1
Preheat oven to 375°F. Line a 12-count muffin pan with cupcake liners, and prepare 2 additional liners in another pan for remaining batter.
- 2
Boil water in a small saucepan. Pour over cocoa powder in a medium heatproof bowl and whisk until smooth. Cool to room temperature in the refrigerator.
- 3
Whisk together flour, baking powder, and salt in a medium bowl. Set aside.
- 4
Beat softened butter and sugar together on medium-high speed until light and creamy, about 2 minutes. Add eggs one at a time, beating until smooth. Scrape down bowl sides as needed. Beat in vanilla extract.
- 5
Add flour mixture and beat only until just combined. Add cooled cocoa mixture in a steady stream on low speed and beat until smooth. Avoid over-mixing.
- 6
Divide batter between muffin liners, filling each about 3/4 full.
- 7
Bake for 16-19 minutes, or until a toothpick inserted in the center comes out mostly clean with no wet crumbs. Cool completely before frosting.
- 8
Beat softened butter on medium-high speed until smooth and creamy, about 2 minutes. Add confectioners' sugar, heavy cream, peppermint extract, and food coloring if using.
- 9
Increase to high speed and beat for 3 minutes. Adjust consistency with more confectioners' sugar if too thin or more cream if too thick. Taste and add salt if needed. Fold in chocolate chips by hand using a rubber spatula.

Frost cooled cupcakes generously using an icing spatula. Serve immediately or store as desired.
Tips
Bloom cocoa powder with boiling water before adding to batter to intensify chocolate flavor and ensure smooth integration. This technique hydrates cocoa particles fully, preventing dry pockets and deepening overall richness.
Cool the cocoa mixture completely before adding to the batter to prevent scrambling eggs and ensure even cake crumb. Refrigerating it while prepping other ingredients speeds the process without compromising texture.
Beat frosting for the full 3 minutes on high speed after adding wet ingredients to incorporate air and achieve light, fluffy texture. This prevents dense, grainy frosting and creates the optimal consistency for piping and spreading.
Good to Know
Cover and refrigerate leftover cupcakes for up to 5 days. Use a cupcake carrier for storing and transporting decorated cupcakes to protect frosting.
Bake cupcakes up to 1 day ahead and store unfrosted at room temperature or refrigerated. Frost no more than 1 day before serving to maintain frosting texture.
Serve at room temperature or chilled. Pairs well with cold milk, coffee, or tea. Ideal for celebrations, parties, or afternoon treats.
Common Mistakes
Do not over-mix batter after adding flour mixture to avoid dense, tough cupcakes.
Do not add cocoa mixture to warm batter to avoid curdling eggs and creating a grainy crumb.
Do not skip the 3-minute high-speed beating of frosting to avoid grainy, dense texture.

Full guide →FAQ
Can I make these cupcakes ahead of time?
Yes. Bake cupcakes up to 1 day in advance and store unfrosted at room temperature or refrigerated. Frost no more than 1 day before serving to maintain frosting texture and appearance. Store decorated cupcakes in a cupcake carrier in the refrigerator.
What if I don't have peppermint extract?
Substitute with fresh mint leaves steeped in the heavy cream before use, or use spearmint extract at the same ratio. Peppermint candy crushed and folded into frosting also works. Adjust quantity to taste since fresh mint yields herbaceous rather than synthetic sweetness.
How long do these cupcakes keep?
Unfrosted cupcakes keep at room temperature for 2 days or refrigerated for up to 5 days in an airtight container. Frosted cupcakes keep covered in the refrigerator for up to 5 days. Store in a cupcake carrier to protect frosting from damage during storage and transport.
