Make the muffins
- Heat the oven to 375°F.
- Line a 12-cup standard muffin pan with paper liners.
- Whisk the flour, cocoa powder, sugar, baking powder, baking soda, and salt in a large bowl.
- In a medium bowl, whisk the eggs, buttermilk, oil, and vanilla until combined.
- Pour the egg mixture into the flour mixture and fold just until no dry streaks remain.
- Fold in the chocolate chips.
- Divide the batter evenly among the muffin cups.
- Bake for 18 to 22 minutes, until a toothpick inserted into the center of a muffin comes out with a few moist crumbs.
Top the muffins
- Immediately press the mini marshmallows gently onto the hot muffin tops.
- Let the muffins rest in the pan for 5 minutes.
- Transfer the muffins to a wire rack.
- Cool for at least 10 minutes before serving.
Notes
For tender muffins, fold the batter only until no dry streaks remain. Store covered in the refrigerator for up to 3 days; freeze for up to 2 months. For a dairy-free swap, use dairy-free buttermilk and chocolate chips, and check that the marshmallows are dairy-free.
