Method
Make the muffins
- Heat the oven to 375°F.
- Line a standard 12-cup muffin pan with paper liners.
- In a large bowl, whisk together the flour, cocoa powder, sugar, baking powder, baking soda, and salt.
- In a medium bowl, whisk the eggs, buttermilk, oil, and vanilla until combined.
- Pour the egg mixture into the flour mixture and stir just until no dry flour remains.
- Fold in the chocolate chips.
- Divide the batter evenly among the muffin cups.
Finish and bake
- Bake for 16 minutes.
- Place 3 mini marshmallows on each muffin.
- Bake for 2–4 minutes more, until the muffins spring back lightly and a toothpick inserted into the cake comes out with a few moist crumbs.
- Cool the muffins in the pan for 5 minutes.
- Transfer the muffins to a wire rack.
Notes
For tender muffins, stir only until no dry flour remains before folding in the chocolate chips. Store covered in the refrigerator for up to 4 days; freeze for up to 2 months. For a dairy-free variation, use dairy-free buttermilk and dairy-free chocolate chips.
