  • Bake at 425°F for 5 minutes. Then, reduce the oven temperature to 350°F and bake for an additional 15 minutes, or until a toothpick inserted in the center comes out clean or with moist crumbs.
  • Remove the muffins to a wire rack and allow them to cool completely before storing.

Notes

*The combination of butter and oil makes these chocolate muffins extra moist and flavorful. If you'd like to use only one form of fat, I recommend using all oil because it will keep the muffins from drying out. The butter adds delicious flavor but will not add as much moisture as the oil.
**While you can use any unsweetened cocoa powder you prefer, I like to use Dutch-process cocoa powder here since it works better with the baking powder.
Tips:
  • Do NOT reduce the amount of sugar in these muffins; otherwise, they may turn out dry.
  • Use room temperature milk and eggs for the fluffiest muffins.
  • Measure the flour using the spoon-and-level method to avoid dense, dry muffins.
  • If your cocoa powder seems lumpy, sift it through a fine-mesh sieve to help it mix in more easily.
  • To enhance the chocolatey flavor, add ½ teaspoon of instant espresso or instant coffee granules.
  • You can add up to ½ cup of other mix-ins, such as chopped nuts, candies, or dried fruits.
  • Don't overmix the batter; otherwise, you will end up with tough muffins.
  • Optionally, let the batter rest for 15-30 minutes at room temperature for a higher rise.
  • Don't open the oven door while the muffins are baking. This could cause them to deflate.
  • Take care not to overbake these muffins; otherwise, they will end up dry.
To Make 12 Muffins: Use the servings slider above to adjust the measurements automatically for a single 12-count tin.
Make-Ahead: Mix the batter completely, cover the bowl tightly with plastic wrap, and refrigerate for up to 18 hours before baking. Add an extra 1-2 minutes to the final bake time.
Storage: Store muffins in an airtight container at room temperature for up to 3 days, in the refrigerator for up to 1 week, or in the freezer for up to 2 months.
