Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.

Whisk together the all-purpose flour, cocoa powder, baking powder, and salt.

Beat the granulated sugar and large eggs together until fluffy. Add in the milk, vegetable oil, vanilla extract, and mint extract; mix until smooth.

Combine the wet mixture with the dry ingredients, stirring until just combined.

Fold in the chocolate chips gently.

Spoon the batter into the prepared muffin tins about two-thirds full, then bake for 18-20 minutes or until a toothpick comes out clean.
