Preheat your oven to 350°F (175°C).

Prepare your loaf pan by greasing it with butter or non-stick spray.

In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt until well combined.

In another bowl, beat the eggs, then add the oil, vanilla extract, and peppermint extract. Mix well until combined.

Pour the wet ingredients into the dry ingredients and mix until just combined. Be cautious not to overmix.

Fold in the mini chocolate chips gently, ensuring an even distribution without overworking the batter.

Pour the batter into your prepared loaf pan, smoothing the top with a spatula.

Bake in the preheated oven for 50-60 minutes, or until a toothpick inserted into the center comes out clean.

Once baked, remove it from the oven and let it cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.

In a small bowl, mix the powdered sugar and milk to create a smooth glaze.

Drizzle the glaze over the top of the cooled loaf, letting it drip down the sides for a beautiful presentation.
