These wholesome oatmeal bars feature a thick, jammy layer of sweet blueberries sandwiched between a soft, tender oat base and a lightly crisp crumble topping. Requiring no refined flour or refined sugar, they blend the warm comfort of morning oatmeal into a convenient, sliceable bar that works beautifully for busy grab-and-go mornings or a wholesome afternoon snack.
Ingredients
1 1/2 cups rolled oats (divided)
1 cup blueberries (fresh or frozen)
2 large eggs
1/3 cup honey or maple syrup
1/2 cup milk (any kind: whole milk, almond, or oat milk)
1 tsp vanilla extract
1/2 tsp ground cinnamon
1/2 tsp baking powder
Pinch of salt
Instructions
1. Prep and Mix the Liquid Base
Preheat your oven to 350°F (175°C). Line an 8×8-inch square baking pan with parchment paper, leaving a little overhang on the sides for easy removal later. In a medium bowl, whisk together the eggs, honey or maple syrup, milk, and vanilla extract until completely smooth.
2. Combine the Dry Ingredients
In a separate large bowl, combine 1 1/4 cups of the rolled oats (reserve the remaining 1/4 cup for the top crumble), ground cinnamon, baking powder, and a pinch of salt. Stir until the spices are evenly distributed throughout the oats.
3. Form the Soft Oat Batter
Pour the whisked liquid ingredients directly into the dry oat mixture. Stir thoroughly with a spatula. The mixture will look quite wet at first; let it sit for about 3 to 5 minutes so the rolled oats can begin absorbing the liquids and thickening up.
4. Layer the Base and Fruit
Pour about two-thirds of your oat batter into the bottom of the prepared baking pan, smoothing it into an even layer with the back of a spoon to create the bottom crust. Scatter your blueberries evenly across this base layer, pressing them down gently so they sit firmly in place.
5. Add the Crisp Crumble Top
Stir the remaining 1/4 cup of dry rolled oats into the last third of your batter to create a thicker, chunkier texture. Spoon this remaining mixture loosely over the blueberries, leaving some gaps so the vibrant purple fruit can peek through, exactly like the rustic, layered look captured in image_73.png.
6. Bake Until Set
Bake at 350°F (175°C) for 25 to 30 minutes. The bars are finished when the center feels firm and the top oats turn a gorgeous, lightly crisp golden-brown.
7. Chill and Slice
Allow the pan to cool completely on a wire rack for at least 20 minutes, then transfer it to the refrigerator for an additional 30 minutes. Chilling is the key secret here—it allows the juicy berry layer to set up firmly, ensuring you get those clean, distinct squares when you slice them up, just like the stack shown in image_73.png.
