Hearty and delicious baked oatmeal muffins made with cinnamon, fruit, and a touch of maple syrup! 


  • 2 1/2 cups old-fashioned rolled oats
  • 1 teaspoon baking powder
  • 1/2 teaspoon kosher salt
  • 1 teaspoon cinnamon
  • 2 tablespoons butter, melted and cooled
  • 2 cups milk
  • 1 egg
  • 1/4 cup honey or maple syrup
  • 2 small apples, chopped (or any 2 cups of chopped fruit)
  • 1/4 cup chopped nuts (optional)


  1. Preheat the oven to 375F and line a muffin pan with 12 paper or silicone liners. 
  2. In a large bowl, combine the oats, baking powder, salt, cinnamon, chopped apples, and nuts if using. 
  3. In a separate medium bowl, whisk the butter, milk, egg, and maple syrup until smooth. Add the wet ingredients to the dry ingredients and stir to combine. 
  4. Evenly distribute the oat batter into the lined muffin pan, filling each cup a little more than 3/4th of the way. Bake for 25 to 30 minutes or until a toothpick comes out clean or with a few moist crumbs. 
  5. Allow the muffins to cool 5 minutes before removing and serving.
