Preheat your oven to 350°F (175°C) and grease a 9x5-inch loaf pan.
In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
In another bowl, mix the milk, vegetable oil, eggs, vanilla extract, and peppermint extract until well combined.
Gradually pour the wet ingredients into the dry ingredients, stirring until just combined. Be careful not to overmix; it's okay if there are a few lumps.
Fold in the semi-sweet chocolate chips and crushed peppermint candies until evenly distributed throughout the batter.
Transfer the batter into the prepared loaf pan, smoothing the top to ensure even baking.
Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Once baked, remove the bread from the oven and allow it to cool in the pan for about 10 minutes. Then, carefully transfer the bread to a wire rack to cool completely.
Notes
Serve slices drizzled with melted chocolate and sprinkled with additional crushed peppermint for a festive touch.
