Begin by preheating your oven to 350°F (175°C). Prepare a mini muffin tin by lining it with paper liners or lightly greasing each cup with cooking spray.
In a large mixing bowl, combine the melted butter with the granulated sugar. Whisk them together thoroughly until the mixture is smooth and homogeneous.
Add the eggs to the butter-sugar mixture one at a time, ensuring that each egg is fully incorporated before adding the next. Then stir in the vanilla extract and peppermint extract, whisking until the batter is silky.
In a separate bowl, sift together the all-purpose flour, unsweetened cocoa powder, salt, and baking powder. Gradually combine the dry ingredients with the wet mixture, stirring gently until just blended—be careful not to overmix.
With a spatula, carefully fold in the peppermint chocolate chips, ensuring they remain intact for delightful bursts of flavor in each bite.
Using a cookie scoop or a spoon, fill each cup of the prepared mini muffin tin with the brownie batter, filling each one about three-quarters full to allow for rising during baking.
Place the tin in the preheated oven and bake for 12-15 minutes, or until a toothpick inserted in the center of one of the brownie bites comes out with a few moist crumbs attached. Be careful not to overbake.
Once baked, remove the mini muffin tin from the oven and let the brownie bites cool in the tin for about 5 minutes. Afterward, gently transfer them to a wire cooling rack to cool completely.
Once the brownie bites are completely cooled, generously sprinkle crushed candy canes over the top for a festive flair and added crunch.
Notes
Arrange the brownie bites on a colorful festive platter and garnish with whole candy canes for a cheerful display.
