Ingredients

Scale
  • 1 ½ cups (135g) old-fashioned rolled oats
  • 1 teaspoon baking powder
  • 1 tablespoon ground cinnamon
  • ½ teaspoon ground nutmeg (optional)
  • ¼ teaspoon salt
  • 1 cup (240ml) milk (dairy or plant-based)
  • ¼ cup (60ml) maple syrup
  • 1 teaspoon vanilla extract
  • 1 large egg (room temperature)
  • 1 large apple, peeled and diced (Granny Smith or Honeycrisp recommended)
  • ½ cup (60g) chopped walnuts or pecans (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 12-cup muffin tin lightly or line with silicone liners.
  2. In a large bowl, combine rolled oats, baking powder, ground cinnamon, ground nutmeg (if using), and salt. Stir until evenly distributed.
  3. In a smaller bowl, whisk together milk, maple syrup, vanilla extract, and egg until smooth.
  4. Pour the wet ingredients into the dry ingredients and gently fold together using a spatula or spoon until combined. Fold in the diced apple and optional chopped nuts.
  5. Spoon the mixture evenly into the muffin cups, filling each about ¾ full without packing down.
  6. Bake for 25-30 minutes until the tops are golden and a toothpick inserted comes out clean or with a few moist crumbs.
  7. Let the oatmeal cups cool in the pan for 10 minutes, then transfer to a cooling rack to cool completely before storing.

Notes

Do not overmix the batter to avoid gummy texture. Use fresh spices for best flavor. Toast nuts before adding for richer taste. Let cups cool fully before storing to maintain shape and texture. For vegan version, replace egg with flax egg and use plant-based milk.
