Preheat oven to 350°F. In a large bowl, combine the flour, baking powder, baking soda, and salt, then set aside.
In a separate bowl, whisk together the melted butter and sugars.
Whisk in the milk, eggs, and vanilla extract until well combined.
Fold in the dry ingredients, mixing until just combined. Then gently fold in the chocolate chips.
Grease a mini muffin tin or line with mini muffin liners. Pour the batter into the mini muffin cups.
Bake at 350°F for 12-13 minutes, or until the muffins are fully baked.
Let the muffins cool in the pan for a few minutes before removing and allowing to cool completely on a wire rack.
Serve or store for later!
Notes
Store your muffins in an airtight container for up to 3 days or up to 3 months in the freezer. Store them with a paper towel on top to keep them fresher for longer!
