Instructions
 

Preparation

  • Preheat the oven to 425°F. Line a 12 cup muffin tin and lightly spray the liners.
  • In a large bowl, whisk together the dry ingredients: flour, cocoa, sugar, baking powder, baking soda, and salt.
  • In another bowl, whisk together the wet ingredients: eggs, milk, yogurt, oil, melted butter, and vanilla until smooth.
  • Pour the wet ingredients into the dry ingredients. Fold gently with a spatula until just combined. Do not overmix.
  • Fold in the chocolate chips, reserving a small handful for topping. Let the batter rest for 10 minutes.

Baking

  • Fill muffin cups nearly to the top. Sprinkle a few chocolate chips on each muffin.
  • Bake at 425°F for 5 to 7 minutes. Without opening the door, reduce the temperature to 350°F and bake for an additional 12 to 16 minutes, until a toothpick has a few moist crumbs.
  • Cool in the pan for 5 minutes, then move muffins to a wire rack. Enjoy warm when the chips are melty.
