These baked oatmeal cups combine soft, chewy oats with juicy blueberries and a bright, tangy lemon glaze for a quick, comforting breakfast or snack.

Ingredients

Scale
  • 2 cups old-fashioned rolled oats (about 180g)
  • 1 teaspoon baking powder
  • 1/2 teaspoon ground cinnamon
  • Pinch of salt
  • 1/4 cup brown sugar (50g) or maple syrup as a substitute
  • 1 1/2 cups milk (360ml), whole milk preferred or almond/oat milk for dairy-free
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 2 tablespoons unsalted butter, melted (or coconut oil for dairy-free)
  • 1 cup fresh or frozen blueberries (150g)
  • 2 tablespoons freshly squeezed lemon juice
  • 1/2 cup powdered sugar (60g), sifted
  • 1 teaspoon lemon zest

Instructions

  1. Preheat oven to 350°F (175°C) and line a 12-cup muffin tin with liners or lightly grease it.
  2. In a medium bowl, combine rolled oats, baking powder, ground cinnamon, and salt.
  3. In a separate large bowl, whisk together milk, egg, brown sugar, vanilla extract, and melted butter until smooth and slightly frothy.
  4. Pour the dry ingredients into the wet ingredients and stir gently until just combined; batter will be thick and a bit lumpy.
  5. Fold in blueberries gently, reserving a few for topping.
  6. Spoon the batter evenly into the muffin tin cups, filling about 3/4 full.
  7. Bake for 25-30 minutes until tops are lightly golden and a toothpick inserted comes out mostly clean.
  8. Let the cups cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
  9. In a small bowl, whisk together powdered sugar, lemon juice, and lemon zest until smooth and pourable.
  10. Drizzle the lemon glaze over the cooled oatmeal cups just before serving.

Notes

Use rolled oats for best texture; frozen blueberries prevent drying out. Let cups cool before glazing to prevent glaze from melting off. Glaze consistency can be adjusted by adding more lemon juice or powdered sugar. These cups freeze well individually wrapped and can be reheated in the microwave.
