Description
Lemon blueberry oatmeal bars are made with a tangy, sweet blueberry filling and a buttery oat crust/crumble. They’re the best grab-and-go breakfast out there!
Ingredients
Scale
For the Crust & Crumble
- 6 tablespoons unsalted butter, melted
- 1 1/2 cups white whole wheat flour
- 1 1/2 cups regular oats (not the instant kind)
- 1/2 cup honey
- 1/4 cup brown sugar
- 1 teaspoon fresh lemon zest
- pinch of salt
For the Lemon Blueberry Filling
- 2 cups of fresh blueberries
- 1/4 cup brown sugar
- 2 tablespoons fresh lemon juice
- 1 teaspoon white whole wheat flour
Instructions
Make the Crumble Mixture
- Preheat oven to 350°F.
- Line the bottom of an 8×8 pan with parchment paper and spray with cooking spray for easy removal.
- To make the crust & crumble, to a large bowl add melted butter, white whole wheat flour, regular oats, honey, brown sugar, lemon zest and salt. Mix until just combined, mixture should be a little crumbly. Scoop out 1 cup of the mixture and set aside, that will be your crumble.
- Add the remaining mixture to the prepared pan. Spread the mixture out and using your fingers press into the bottom of the pan so the crust is in an even layer.
Make the Filling & Assemble the Bars
- To a small bowl add blueberries, brown sugar, lemon juice, and white whole wheat flour. Toss to combine.
- Add the blueberry mixture on top of the crust and spread out evenly.
- Evenly sprinkle the crumble mixture over the top of the bars.
- (optional: dust the top of crumble with cinnamon)
- Bake the bars for 50 minutes. Remove the bars from the pan and let sit for 10 minutes. Cut and serve.
Notes
- Makes 12-16 bars.
- Recipe adapted from Averie Cooks.
- To Store: Keep cooled bars in an airtight container at room temperature for up to 24 hours, then transfer them to the fridge for up to 2 additional days. Note that the crumble will get less crispy as the bars sit.
- To Reheat: I like to warm up my oatmeal bars in the toaster oven before I enjoy them, but you can serve them at room temperature if preferred. I don’t recommend reheating them in the microwave as it would further soften the crust and topping.
- To Freeze: Place cooled bars into a freezer-safe container and store for up to 3 months, placing a piece of parchment paper between layers if stacking is needed. Thaw in the fridge before reheating/enjoying. The freezing process will make the crumble a lot less crispy, but the bars will still be divine!
