1 1/2 cups multi-purpose flour
1 cup rolled oats (I like to chop them in the Eco-Chop first)
1/2 cup white sugar
2 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon salt
3/4 cup milk
1/3 cup vegetable oil
1/2 teaspoon vanilla extract
3/4 cup Nutella
2. In a different bowl, beat the egg lately. Stir in the milk, oil, and vanilla. Add to the mashed banana, and combine thoroughly. Stir the liquid mixture into dry mixture until just combined.
3. Fill the muffin cups about halfway full of batter, and then place a tablespoon of Nutella on top of each. Swirl the Nutella into the batter using a toothpick.
4. Bake at 400° for about 12 minutes for mini muffins, or 15 minutes for regular size muffins.
These would work great in any of the other Trays as well!
