Preheat the oven to 375 degrees F. Fill a mini muffin tin with paper baking cups.
In a large bowl whisk together the eggs, milk and vanilla extract. Add in the melted butter.
In a separate bowl, whisk together the flour, sugar, baking powder, and salt.
Fold in the dry ingredients into the wet ingredients. Stir only until combined.
Stir in the chocolate chips, being careful not to over mix.
Fill each muffin cup about 3/4 of the way.
Bake at 350F for 10-14 minutes.
To check for readiness, insert a toothpick in the muffins to see if they come out clean.
Cool in the pan for 5 minutes and then transfer to a wire rack.
