Garlic-onion dinner muffins

Description
These are easy and tasty. I serve these muffins with my Vaca Frita #59433. Recipe is from 'Taste of Cuba'



Ingredients
cooking spray
 * 2 cups flour
 * 3 teaspoons baking powder
 * 1 teaspoon salt
 * 2 tablespoons sugar
 * 1 egg, beaten
 * 1 cup milk
 * 1/4 cup melted butter
 * 2 cloves garlic, minced
 * 1 medium onion, diced

Directions

 * Heat oven to 400°.
 * In a large mixing bowl, mix together the flour, baking powder, salt and sugar.
 * In a small bowl, mix together the egg, milk, butter, garlic and onion.
 * Make a well in the center of the dry ingredients and pour in the egg mixture; mix together, using as few strokes as possible (do not overbeat, the batter should have some small lumps in it).
 * pour the batter into lightly sprayed (with cooking spray) muffin tins, filling them 2/3 full, and bake 20 minutes.
 * Test for doneness (insert toothpick into the center, if it comes out clean, they're done); remove the muffins from the tins and place on a wire rack to cool slightly before serving.
