Preheat your oven to 375 degrees Fahrenheit and lightly spray your mini muffin cups with nonstick cooking spray.
In a large bowl whisk together the flour, sugars, baking powder, and salt.
In a separate medium bowl combine the egg, milk, butter, and vanilla.
Next, add the wet ingredients into the dry ingredients until everything has combined.
Then, fold in the mini chocolate chips.
Spoon the batter into the prepared mini muffin cups about ¾ of the way full. Note: If you have a small cookie scoop this is the perfect size for these muffin liners.
Bake in the preheated oven for 12-15 minutes or until the muffins are lightly golden brown.
Finally serve and enjoy!
