Cinnamon Chocolate Chip Muffins

Batter:
2/3 cup sugar
1/2 teaspoon salt
1 Tablespoon vanilla extract
2 teaspoons baking powder
1 teaspoon cinnamon
2/3 cup milk
2 eggs
1/2 cup butter, melted and cooled
2 cups flour
1 bag chocolate chips

Struesel Topping:
1/2 cup brown sugar
1/3 cup flour
1 teaspoon cinnamon
1/2 teaspoon nutmeg
1/4 cup butter at room temprature

Preheat over to 400 and line muffin tins with paper or grease liberally. With a fork, blend all ingredients for batter except for the flour until smooth. Using a spoon, fold in flour until all moistened - allow the batter to remain lumpy. Fold in chocolate chips and fill muffin tins to brim. Top each muffin with struesel topping. Bake 15-18 minutes. Remove to cooling rack for a few minutes - serve warm.
