Ingredients
Dry Ingredients
- 1 cup old-fashioned oats
- ¾ cup all-purpose flour
- ⅓ cup light brown sugar
- ¼ tsp baking soda
- ¼ tsp salt
- ½ tsp cinnamon (optional)
Wet Ingredients
- 6 tbsp unsalted butter, melted
- 1 tsp vanilla extract
Blueberry Filling
- 1 cup blueberries
- ¼ cup granulated sugar
- 2 tsp cornstarch
Instructions
- Preheat to 375°F (190°C). Line an 8-inch square pan with parchment paper.
- Combine oats, flour, brown sugar, baking soda, salt, and cinnamon in a large bowl.
- Stir in melted butter and vanilla until crumbly.
- Press half of the oat mixture into the pan evenly.
- Toss blueberries with sugar and cornstarch; spread evenly over the base.
- Crumble remaining oat mixture over blueberries and lightly press. Bake 35–40 minutes until golden and bubbly.
- Cool completely on a wire rack. Lift out with parchment overhang and cut into 12 bars.
Notes
- Room Temperature Ingredients: Using melted butter or coconut oil at the right temperature helps the oat mixture combine evenly for a soft, chewy texture.
- Fresh vs. Frozen Blueberries: Both work! If using frozen, do not thaw—toss directly with sugar and cornstarch to prevent watery bars.
- Pressing the Base: Make sure the bottom layer of oats is pressed firmly; this creates a stable crust that holds the filling.
- Cooling Time is Key: Let bars cool completely before slicing. Cutting too early can cause the bars to fall apart.
- Optional Add-ins: Sprinkle nuts, chocolate chips, or seeds on top for extra flavor and texture.
- Sweetness Adjustments: For a lighter sweetness, reduce the granulated or brown sugar slightly—blueberries add natural sweetness.
- Make-Ahead & Freezing: These bars freeze beautifully. Wrap individually for easy grab-and-go snacks.
- Serving Suggestion: Perfect with Greek yogurt, a cup of coffee, or fresh berries for a balanced snack or breakfast.
