Double Chocolate Chip Muffins

Ingredients

1 1/4 cups all-purpose flour (see Cook’s Note)
1/2 cup unsweetened cocoa powder
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon fine salt
1 cup bittersweet chocolate chips
3/4 cup milk
1/2 cup packed light brown sugar
4 tablespoons unsalted butter, melted
1 tablespoon vegetable oil
2 teaspoons pure vanilla extract
2 large eggs

Directions

Preheat the oven to 350 degrees F. Line 12 muffin cups with paper liners.

Whisk together the flour, cocoa powder, baking powder, baking soda and salt in a large bowl. Stir in the chocolate chips. In a medium bowl, whisk together the milk, brown sugar, butter, oil, vanilla and eggs until smooth.

Quickly fold the milk mixture into the flour mixture with a rubber spatula. Divide the batter evenly among the prepared muffin cups. Bake until a toothpick inserted in the center comes out clean, about 25 minutes. Transfer the muffins from the pan to a wire rack to cool.
