Blueberry Baked Oatmeal Bars
Blueberry Baked Oatmeal Bars
Rolled oats, Greek yogurt, eggs, almond milk, and blueberries bake into six breakfast bars. A modest amount of maple syrup gives defined sweetness, while resting the batter hydrates oats before baking.
Details
- Yield: 6 bars
- Prep: 12 minutes
- Rest: 10 minutes
- Bake: 28–34 minutes
- Equipment: 9-inch square metal pan, parchment, bowls, whisk, spatula, thermometer
Ingredients

- 1 teaspoon baking powder
- 1/2 teaspoon cinnamon
- 1/4 teaspoon salt
- 4 large eggs
- 1 cup plain Greek yogurt
- 1 cup unsweetened almond milk
- 1/3 cup maple syrup
- 1 teaspoon vanilla
- 1 cup blueberries, dry
- Cooking spray
Method
- Heat oven to 350°F. Spray and line the pan.
- Mix oats, baking powder, cinnamon, and salt.
- Whisk eggs, yogurt, milk, syrup, and vanilla. Stir into oats and rest 10 minutes.
- Fold in blueberries and spread evenly in pan.
- Bake 28–34 minutes, until center is set, edges are lightly golden, and center reaches 160°F.
- Cool 15 minutes, lift out, and cut into six rectangles.
Ingredient function and cues
Oats absorb milk during resting and form the bar structure. Eggs bind the mixture, while yogurt adds moisture and tenderness. Baking powder prevents a heavy center. Dry blueberries limit colored streaks and excess water.
The finished center should not slosh when the pan is nudged. A pick may encounter juicy fruit, so pair it with the temperature test. If using frozen berries, fold them in frozen and expect several extra minutes; thawed berries release too much juice. Do not add extra milk when the mixture initially looks loose because oats continue absorbing it.
Serving and substitutions
Serve warm or cold with additional yogurt. Dairy milk can replace almond milk. Honey can replace maple syrup. Quick oats create a softer bar; steel-cut oats are unsuitable. Raspberries can replace blueberries but should be folded gently.
Storage
Refrigerate covered for up to 4 days. Reheat to 165°F if desired. Freeze individual bars for up to 2 months and thaw overnight in the refrigerator. The existing body contains promotional subscription-style links, which should not be retained; use only owner-original matching media.
Pan and portion guidance
A 9-inch square pan produces bars thick enough to stay moist while setting through. A 9-by-13-inch pan spreads this quantity too thin and requires a different baking time. Metal gives predictable edge browning; glass retains heat longer, so the bars may continue cooking after removal.
Cool before lifting with the parchment. Mark the slab into two rows by three rows, then cut with a clean chef’s knife. If a blueberry drags through the crumb, wipe the blade before the next cut. For portable breakfasts, wrap bars only after complete cooling; trapped steam makes the surfaces sticky. Keep any yogurt topping separate until serving.
