Preheat oven to 375 degrees F
(190 degrees C). Position rack in center of oven. Butter, or line with paper
liners, 12 - 2 3/4 x 1 1/2 inch muffin cups.
In a large
measuring cup or bowl whisk together the melted butter, eggs, buttermilk, and
In another large
bowl whisk together the flour, cocoa powder, sugar, baking powder, baking soda,
and salt. Stir in the chocolate chips. With a rubber spatula fold the wet
ingredients into the dry ingredients and stir only until the ingredients are
combined. Do not over mix the batter or tough muffins will result.
Evenly fill the
muffin cups with the batter (the muffin cups will be full), using two spoons or
an ice cream scoop. Place in the oven and bake until a toothpick inserted in the
center of a muffin comes out clean, about 20 minutes. Transfer to a wire rack
and let cool for about 5 minutes before
removing from pan.
