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, use a mixer to combine the egg, milk, butter, and vanilla extract.
Next, add the wet ingredients mixture into the dry ingredients and use a mixer to mix 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!
