2 c. Bisquick baking mix
1/4 c. sugar
2/3 c. milk
1 c. mini semi-sweet chocolate chips (I use regular size and it comes out fine)
1/4 c. chopped nuts (optional)
2 Tbsp. sugar
2 tsp. cinnamon
Preheat oven to 400*F.
Cinnamon sugar topping: mix 2 Tbsp. sugar and 2 tsp. cinnamon together in a bowl and set aside.
Combine Bisquick, sugar, egg, and milk. Beat with a spoon till combined (will be lumpy). Stir in mini chips and nuts, if using.
Fill greased or lined muffin cups 3/4 full with batter. Sprinkle each muffin with 1/2 tsp. sugar-cinnamon topping.
Bake 15-17 minutes or until lightly browned. Serve warm with butter.
