Ingredients

Scale
  • 2 cups (180g) rolled oats
  • 1 ½ cups (360ml) milk (any kind)
  • 2 large eggs
  • ⅓ cup (80ml) honey or maple syrup
  • 3 tablespoons unsalted butter or coconut oil, melted
  • 1 teaspoon vanilla extract
  • 1 ½ teaspoons ground cinnamon
  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • 1 large or 2 small apples, peeled and diced (about 1 cup)
  • Optional: ½ cup chopped walnuts or pecans
  • Optional: ¼ cup raisins or dried cranberries
  • Optional: 1 tablespoon sugar mixed with ½ teaspoon cinnamon for topping

Instructions

  1. Preheat oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease each cup.
  2. Peel and dice the apple into small ¼-inch pieces. Set aside.
  3. In a large bowl, whisk together rolled oats, baking powder, cinnamon, and salt.
  4. In a separate bowl or large measuring cup, whisk together milk, eggs, honey or maple syrup, melted butter or coconut oil, and vanilla extract until smooth.
  5. Pour wet ingredients into dry ingredients. Stir with a rubber spatula until just combined. Fold in diced apples and any optional mix-ins.
  6. Let the batter rest for 5 minutes.
  7. Spoon batter evenly into prepared muffin cups, filling each about ¾ full.
  8. Optional: Sprinkle cinnamon-sugar mixture over the tops.
  9. Bake for 20-25 minutes, until a toothpick inserted in the center comes out mostly clean.
  10. Let cool in the pan for 5 minutes, then transfer to a cooling rack to cool completely.

Notes

Let the batter rest for 5 minutes before baking for a softer texture. Use room temperature ingredients to prevent butter from seizing. Cool completely before storing to avoid sogginess. These freeze well for up to 3 months.
