Sugar Crusted Chocolate Chip Muffins

I made these a while back when some friends came into town.  They were delicious and such a fun treat.  The recipe is slightly adapted from Simply Scratch.

2 cups All-Purpose Flour
1/2 cup Sugar
3 tsps baking powder
1/2 tsp Kosher Salt
1 cup Whole Milk
1/3 cup Vegetable Oil
1/2 tsp Vanilla Extract
1 egg
3/4 cup Mini Semi-Sweet Chocolate Chips
3 tbsp White Sugar (for sugar crust)
2 tbsp Dark Brown Sugar (for sugar crust)

Preheat oven to 375.  Fill a muffin tin with baking cups.  In a small bowl mix together 3 tablespoons of white sugar and 2 tablespoons of dark brown sugar and set to the side.  In a medium size bowl combine flour, sugar, baking powder, chocolate chips and salt.  In a different bowl mix together the milk, oil, vanilla extract and egg.  Mix the wet ingredients into the dry.  Fill the baking cups 2/3 of the way and sprinkle with sugar topping.  Bake for 18 to 20 minutes or until done.  Cool for several minutes then remove from muffin tin.
