Ingredients

2 cups (10 ounces) all-purpose flour
½ cup (1½ ounces) cocoa powder
2 teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
¾ cup (5¼ ounces) granulated sugar
2 large eggs
⅓ cup vegetable oil
1 cup plus 2 tablespoons milk
1 teaspoon pure vanilla extract
1 tablespoon espresso powder
1½ cups chocolate chips, divided

Instructions

Preheat the oven to 375°F (190°C) and position the oven rack in the center. Lightly grease a standard 12-cup muffin pan with nonstick cooking spray.
In a medium bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
In a large mixing bowl, whisk the granulated sugar and eggs until light and slightly frothy, about 30 seconds.
Add the vegetable oil, milk, vanilla extract, and espresso powder. Whisk until well combined.
Gradually add the dry ingredients to the wet ingredients and stir until just combined. Do not overmix.
Fold in 1 cup of the chocolate chips.
Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full.
Sprinkle the remaining ½ cup chocolate chips evenly over the tops of the muffins.
Bake for 17–19 minutes, or until the tops are set and a toothpick inserted in the center comes out with a few moist crumbs.
Allow the muffins to cool in the pan for 15 minutes.
Transfer the muffins to a wire rack to cool completely before serving.

Notes

Espresso powder enhances the chocolate flavor without making the muffins taste like coffee.
Do not overmix the batter, as this can result in dense muffins.
Use semi-sweet, dark, or milk chocolate chips based on your preference.
Store muffins in an airtight container at room temperature for up to 3 days.
Freeze cooled muffins for up to 3 months and thaw at room temperature before serving.
