1 stick butter
2 eggs
1 c. sugar
2 c. flour
Fresh grated peel of 1 orange (1 1/2 tsp. to 1 tbsp.)
1 c. buttermilk
1/2 tsp. baking soda
1 tsp. baking powder
1 c. miniature chocolate chips

Beat butter and sugar until creamed. Beat in eggs. Add grated orange peel. In separate bowl, combine buttermilk and baking soda and powder. (Don't worry it if curdles.) Squeeze the juice from the orange (6 to 8 tablespoons) into buttermilk. Add buttermilk and flour alternately 1/3 at a time into butter mixture. Fold until just combined. Fold in chocolate chips. (Don't overmix.) Spoon into muffin pan. Bake at 375 degrees until golden brown, about 20 minutes.
