Lemon blueberry baked oatmeal cups are a bright, cozy, and easy breakfast idea for busy mornings when you want something homemade without standing over the stove. They bring together hearty rolled oats, juicy blueberries, fresh lemon zest, and a lightly sweet flavor that feels like a soft blueberry muffin, but with the comfort of baked oatmeal.

These oatmeal cups are perfect for meal prep because they bake in a muffin tin, store well, and are easy to grab during the week. The lemon adds a fresh bakery-style flavor, while the blueberries become warm and jammy inside each cup. They are simple enough for weekday breakfasts, but pretty enough to serve with yogurt, fruit, or coffee on a slow weekend morning.

If you need a make-ahead breakfast that feels fresh, wholesome, and family-friendly, these lemon blueberry baked oatmeal cups are a great recipe to keep in your rotation.

Ingredients

Instructions

  1. Step 1

    Preheat the oven to 350°F. Lightly grease a 12-cup muffin tin or use silicone muffin liners.

  2. Step 2

    In a large bowl, combine the rolled oats, baking powder, cinnamon, and salt.

  3. Step 3

    In a separate bowl, whisk together the eggs, milk, maple syrup, Greek yogurt, melted butter, vanilla extract, lemon zest, and lemon juice.

  4. Step 4

    Pour the wet mixture over the oats and stir until everything is evenly combined.

  5. Step 5

    Gently fold in the blueberries, keeping a few aside to place on top of each oatmeal cup.

  6. Step 6

    Divide the mixture evenly between the muffin cups. Fill each cup almost to the top and press the mixture down lightly with a spoon.

  7. Step 7

    Add a few extra blueberries on top and sprinkle with chopped nuts if using.

  8. Step 8

    Bake for 22–25 minutes, or until the oatmeal cups are set and lightly golden around the edges.

  9. Step 9

    Let them cool in the pan for 10 minutes before removing.

  10. Step 10

    Serve warm, at room temperature, or chilled with yogurt, honey, or a splash of milk.

Recipe notes

Fresh blueberries give the best texture, but frozen blueberries can be used without thawing.
Use silicone liners if you want the cups to release more easily.
Add extra lemon zest if you prefer a stronger lemon flavor.
For a dairy-free version, use dairy-free milk and a dairy-free yogurt alternative.
Do not overbake; the cups should stay soft and tender inside.

Storage tips

Store the oatmeal cups in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave for 15–25 seconds, or enjoy them cold as a grab-and-go breakfast. They can also be frozen for up to 2 months.

Nutrition note

These oatmeal cups offer a balanced breakfast-style option with oats, fruit, and a moderate amount of natural sweetness. For extra protein, serve them with Greek yogurt or a small spoonful of nut butter.
