Ingredients

Topping:

1/4 cup quick-cooking oats

2 tablespoons brown sugar

1 tablespoon melted butter

1/2 teaspoon ground cinnamon

Muffins:

1 cup quick-cooking oats

1 cup all-purpose flour

1/3 cup brown sugar

1 teaspoon ground cinnamon

1 teaspoon baking powder

1/2 teaspoon baking soda

1/4 teaspoon salt

1/2 cup unsweetened applesauce

1/2 cup milk

1/4 cup vegetable oil

1 large egg, lightly beaten

1 teaspoon vanilla extract

1 medium apple, peeled, cored, and chopped

Instructions

  1. Preheat oven to 400°F (204°C). Grease a 12-cup muffin tin or line with paper liners.
  2. In a small bowl, mix the topping ingredients: oats, brown sugar, melted butter, and cinnamon. Set aside.
  3. In a large bowl, whisk together oats, flour, brown sugar, cinnamon, baking powder, baking soda, and salt.
  4. In another bowl, whisk applesauce, milk, oil, egg, and vanilla until well combined.
  5. Stir wet ingredients into dry ingredients until just moistened. Gently fold in the chopped apple.
  6. Spoon the batter into the muffin cups, filling each about 2/3 full. Sprinkle topping evenly over each muffin.
  7. Bake for 15 minutes, or until a toothpick inserted into the center comes out clean.
  8. Cool in pan for 5 minutes, then transfer to a wire rack to cool completely.

Notes

  • Add walnuts or raisins for extra texture.
  • Substitute chopped apple with grated carrot or zucchini for variation.
  • Drizzle with glaze for a sweeter finish.
  • Add pumpkin spice or nutmeg for a seasonal twist.
  • Let batter rest 10–15 minutes if using old-fashioned oats.
