Instructions:
Preheat your oven:
Preheat the oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease the muffin cups.
Mix the Dry Ingredients:
In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
Mix the Wet Ingredients:
In a large bowl, whisk together the melted butter, granulated sugar, and brown sugar until well combined.
Add the eggs and vanilla extract, and whisk until smooth.
Combine the Ingredients:
Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined.
Fold in the chocolate chips or chunks.
Fill the Muffin Tins:
Divide the batter evenly among the prepared muffin cups, filling each about 3/4 full.
Bake the Muffins:
Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Let the muffins cool in the tin for 5 minutes, then transfer them to a wire rack to cool completely.
Enjoy your rich and fudgy chocolate muffins!
