I found this recipe on http://www.cinnamonspiceandeverythingnice.com. I really like this muffin recipe and I love how the outside of the muffin gets crispy like a cookie.
I baked my muffins for about 23 minutes instead of the 30 minutes, since the outside were getting nicely browned. I used mini chocolate chips since I had some and they really fill up every bite with chocolate goodness!
1/2 cup (8 tablespoons) butter
1 cup granulated sugar
2 teaspoons baking powder
1/2 teaspoon salt
1 teaspoon vanilla extract
1/2 teaspoon cinnamon
1/2 cup (4 ounces) milk
2 cups (8 1/2 ounces) white whole wheat flour or all-purpose floor
2 cups (12 ounces) semi-sweet chocolate chips
coarse sugar, for topping
1. Preheat oven to 350F. Lightly grease a 12-cup muffin pan.
2. In a large mixing bowl beat the butter, sugar, baking powder, salt, vanilla and cinnamon until fluffy. Beat in eggs, then stir in the milk. Mix in the flour just until combined, then the chocolate chips.
3. Divide the batter evenly among the muffin cups. Sprinkle with a little coarse sugar. Bake the muffins for 30 minutes, or until cake tester inserted into the center comes out clean.
