Soft, buttery mini chocolate chip muffins that come together in one bowl—no mixer needed. Perfect for quick breakfasts, lunchboxes, or bite-size treats.
Preheat oven to 375°F. Lightly grease a 24-cup mini muffin pan or line with mini paper liners.
In a large bowl, whisk flour, baking powder, and salt until combined.
Add granulated sugar and brown sugar to the bowl and whisk to break up any lumps.
In a separate bowl or measuring cup, whisk egg, milk, oil, and vanilla until smooth.
Pour wet ingredients into the dry ingredients and stir gently with a spatula just until no dry streaks remain. Do not overmix.
Fold in the mini chocolate chips.
Divide batter evenly among muffin cups, filling each about 0.75 full.
Bake for 10 to 12 minutes, or until the tops spring back when lightly pressed and a toothpick comes out with a few moist crumbs.
Cool in the pan for 5 minutes, then transfer muffins to a wire rack to cool completely.
Notes
Storage: Keep in an airtight container at room temperature for up to 3 days or freeze for up to 2 months. For taller, bakery-style tops, let the batter rest for 10 minutes before baking. You can substitute melted unsalted butter for the oil for a richer flavor.
