Make bakery-quality double chocolate chip muffins at home. This one-bowl recipe yields rich, deeply flavorful, and incredibly moist muffins with high tops, perfect for breakfast or dessert.

Ingredients

Scale
  • 1 ¾ cups all-purpose flour
  • ¾ cup unsweetened cocoa powder
  • 1 cup granulated sugar
  • ½ cup packed brown sugar
  • 1 tablespoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup milk
  • ½ cup vegetable oil
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup semi-sweet or dark chocolate chips
  • ½ cup extra chocolate chips for topping

Instructions

  1. Preheat your oven to 400°F (200°C). Line a 12-cup muffin tin with paper liners or grease well.
  2. In a large bowl, whisk together the flour, cocoa powder, granulated sugar, brown sugar, baking powder, baking soda, and salt. This is your dry mixture.
  3. In a separate medium bowl, whisk together the milk, vegetable oil, eggs, and vanilla extract until combined.
  4. Pour the wet ingredients into the dry ingredients. Mix gently with a spatula until just combined. Do not overmix; a few streaks of flour are acceptable.
  5. Fold in 1 cup of chocolate chips until they are evenly distributed throughout the batter.
  6. Divide the batter evenly among the 12 muffin cups, filling each about two-thirds full. Sprinkle the remaining ½ cup of chocolate chips over the tops of the batter.
  7. Bake at 400°F (200°C) for 5 minutes. This initial high heat helps create tall tops.
  8. Reduce the oven temperature to 375°F (190°C) and continue baking for another 15 to 18 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached.
  9. Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For extra moist chocolate muffins, use buttermilk instead of regular milk.
  • To achieve perfect bakery-style muffin tops, ensure your oven is fully preheated to 400°F before you place the muffins inside for the initial bake.
  • These homemade chocolate muffins stay soft for days when stored in an airtight container at room temperature.
