Preheat the oven to 375 degrees F and grease 10 cups of a standard muffin tin.
Stir together all ingredients in a medium bowl.
Spoon the batter evenly into the muffin cups, using about ¼ cup batter in each one.
Bake for 20-22 minutes or until a cake tester inserted into the center comes out cleanly. Let rest in the pan for a few minutes, then remove from the pan and let cool on a wire rack.
