Notes: I am surprising myself in saying this, but I modified this recipe to half the original amount of chocolate chips. It was just too rich and too dense with an entire bag of chips. Half a bag would be fine. And then just eat the other half of the bag while you are waiting for these to bake. :-)
2 cups all-purpose flour
1/3 cup light-brown sugar
1/3 cup sugar
2 teaspoon baking powder
1/2 teaspoon salt
2/3 cup milk
1/2 cup butter -- melted and cooled
2 eggs - beaten
1 teaspoon vanilla
1/2 package (6 oz) chocolate chips
1/2 cup walnuts or pecans -- chopped (optional)
Preheat oven to 400 F. and grease up twelve muffin cups.
In a large bowl, stir together flour, sugars, baking powder, and salt. In another bowl, stir together milk, eggs, butter, and vanilla until blended. Make a well in center of dry ingredients; add milk mixture and stir just to combine. Stir in chocolate chips and nuts.
Spoon batter into muffin cups; bake 15-20 minutes, or until a knife inserted in center of one muffin comes out clean. Remove muffin tin to wire rack; cool 5 minutes and remove from tins to finish cooling.
