Bake tender lemon blueberry oatmeal cups in lidded custard cups for a practical make-ahead breakfast with simple ingredients and three hardworking Kiss the Cook tools.

Some breakfasts are easiest when they do a little work before the morning rush starts. These mini lemon blueberry baked oatmeal cups are exactly that kind of recipe: hearty enough to feel like breakfast, bright enough to feel fresh, and simple enough to mix up while dinner is in the oven. Baking them in individual cups means you get tidy portions that cool quickly, stack neatly in the refrigerator, and reheat well on busy weekdays.

The flavor lands in a good late-summer spot. Blueberries bring jammy sweetness, lemon zest keeps the oats from tasting flat, and a little maple syrup rounds everything out without pushing the recipe too far into dessert territory. If you like breakfasts that are practical but still feel homemade, this is a strong one to keep in rotation.

Why This Recipe Works

Old-fashioned rolled oats hold their texture better than quick oats, so the finished cups stay tender instead of mushy. Eggs and milk help the oatmeal set into scoopable portions, while melted butter adds just enough richness to make the tops lightly golden. Blueberries can be fresh or frozen, which makes this recipe easy to repeat after peak berry season passes.

This is also the sort of recipe that quietly rewards a few dependable kitchen tools. Glass custard cups make portioning easy and come with lids for storage. A small mesh strainer is handy if you want a light dusting of powdered sugar before serving. And a cake tester gives you a fast way to check the centers without overbaking.

Recipe Card

Mini Lemon Blueberry Baked Oatmeal Cups

Prep time: 15 minutes
Cook time: 28 minutes
Total time: 43 minutes
Yield: 8 oatmeal cups

Ingredients

• 2 cups old-fashioned rolled oats
• 1 teaspoon baking powder
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon kosher salt
• 1 3/4 cups milk
• 2 large eggs
• 1/3 cup maple syrup
• 2 tablespoons melted butter, plus a little more for greasing the cups
• 1 teaspoon vanilla extract
• 1 tablespoon finely grated lemon zest
• 1 cup blueberries, fresh or frozen
• Optional for serving: plain yogurt, extra blueberries, powdered sugar

Directions

1. Heat the oven to 350 degrees F. Lightly grease 8 six-ounce custard cups and set them on a sheet pan so they are easier to move in and out of the oven.
2. In a medium bowl, stir together the oats, baking powder, cinnamon, and salt.
3. In a second bowl, whisk the milk, eggs, maple syrup, melted butter, vanilla, and lemon zest until fully combined.
4. Pour the wet ingredients into the oat mixture and stir until everything is evenly moistened. Fold in the blueberries gently so they do not burst too much.
5. Divide the mixture evenly among the prepared cups, filling each about three-quarters full. Bake for 26 to 30 minutes, until the tops look set and lightly golden around the edges.
6. Check one cup near the center of the pan with a cake tester or thin knife. It should come out mostly clean, and the center should feel set rather than loose. Let the cups cool for 10 minutes before serving warm or cooling completely for storage.

Notes

• If using frozen blueberries, add them straight from the freezer so they keep their shape better in the batter.
• For a slightly sweeter finish, dust the cooled tops lightly with powdered sugar using a fine mesh strainer.
• If you prefer a softer texture, let the oat mixture stand for 5 minutes before portioning so the oats begin absorbing the liquid.

Storage and Food Safety

Because this recipe contains milk and eggs, baked oatmeal cups should reach a safe doneness with set centers before serving. If you want an extra check, the internal temperature in the center should reach 165 degrees F. Do not leave the baked cups at room temperature for more than 2 hours. Cool leftovers, cover, and refrigerate promptly. Stored in the refrigerator, they keep well for up to 4 days. Reheat individual cups in the microwave until hot throughout, or warm several cups in a 300 degree F oven until heated through.
