Lemon blueberry oatmeal bars with honey and brown sugar

Lemon blueberry oatmeal bars are a delightful treat that combine the tanginess of lemon, the sweetness of blueberries, and the wholesome goodness of oatmeal. These bars are perfect for a quick snack, breakfast on-the-go, or a delightful dessert. By using honey and brown sugar, we add a natural sweetness that enhances the flavor without being overly sugary.

Instructions:

1. Preheat the Oven:
- Preheat your oven to 350°F (175°C). Grease a 9x9 inch baking pan or line it with parchment paper for easier removal.
2. Prepare the Crust and Topping:
- In a medium saucepan, melt the 6 tablespoons of butter over medium heat.
- Once melted, remove the saucepan from heat and stir in 1/2 cup honey (170g) and 1/4 cup brown sugar (54g) until fully combined.
- Add 1.5 cups of all-purpose white wheat flour (190g), 1.5 cups multi-grain oatmeal (120g), 1 tsp lemon zest (2g), and a dash of salt (0.40g) to the butter mixture. Stir until everything is thoroughly mixed and crumbly.
3. Form the Base Layer:
- Press about two-thirds of the oatmeal mixture into the bottom of the prepared baking pan to form an even layer. Set aside the remaining mixture for the topping.
4. Prepare the Blueberry Filling:
- In a mixing bowl, combine 2 cups of blueberries (300g), 1/4 cup brown sugar (54g), 2 tablespoons of lemon juice (30g), and 1 tsp all-purpose white wheat flour (2.60g). Toss until the blueberries are evenly coated.
5. Assemble the Bars:
- Spread the blueberry filling evenly over the crust in the baking pan.
- Sprinkle the remaining oatmeal mixture evenly over the blueberry filling, pressing down gently.
6. Bake:
- Bake in the preheated oven for 30-35 minutes, or until the top is golden brown and the blueberries are bubbly.
7. Cool and Serve:
- Allow the bars to cool completely in the pan before cutting into squares. This will help them set and be easier to cut.
8. Enjoy:
- Serve the lemon blueberry oatmeal bars as a delicious snack or dessert. Enjoy!

The bars are done when the top is golden brown and the blueberry filling is bubbly. You can also insert a toothpick to check; it should come out clean or with just a few crumbs.

- Zest the lemon before juicing it to get the best results and to avoid any waste.

- Press the oatmeal mixture firmly in the baking dish to create a solid base and topping that holds together well.
