Crushed candy canes or chocolate shavings (optional, for topping)
Instructions
Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line with parchment paper.
In a medium bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
In a large bowl, whisk together sugar, eggs, sour cream, milk, vegetable oil, vanilla, and peppermint extract until smooth.
Gradually mix dry ingredients into the wet ingredients until just combined. Be careful not to overmix.
Stir in the boiling water. The batter will be thin; this helps make the loaf moist and tender.
Pour batter into prepared pan and bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean. If the top starts to brown too quickly, cover with foil.
Allow the loaf to cool for 10 minutes in the pan, then transfer to a wire rack to cool completely.
