Ingredients You’ll Need
For the Crust & Topping:
- 1 ½ cups old-fashioned oats
- 1 ¼ cups all-purpose flour
- ½ cup brown sugar
- ½ tsp cinnamon
- ¼ tsp salt
- ½ tsp baking soda
- ½ cup unsalted butter, melted
- 1 tsp vanilla extract
For the Blueberry Filling:
- 2 cups fresh or frozen blueberries
- ¼ cup granulated sugar
- 1 tbsp cornstarch
- 1 tbsp lemon juice
- ½ tsp vanilla extract
Step-by-Step Instructions
Step 1: Preheat & Prepare the Baking Pan
- Preheat the oven to 350°F (175°C).
- Line an 8×8-inch baking pan with parchment paper and lightly grease it.
🔥 Why use parchment paper? It makes removing the bars easier and prevents sticking.
Step 2: Make the Crust & Topping
- In a mixing bowl, combine:
✔ Old-fashioned oats
✔ All-purpose flour
✔ Brown sugar
✔ Cinnamon
✔ Salt
✔ Baking soda - Stir in melted butter and vanilla extract until the mixture is crumbly.
💡 Want extra crunch? Add ¼ cup chopped walnuts or pecans for a nutty texture.
3 Step: Press the Crust
- Take two-thirds of the oat mixture and press it firmly into the bottom of the prepared pan.
- Set aside the remaining one-third for the topping.
🔥 Pro Tip: Pressing the crust firmly helps create a solid base that holds up when cutting the bars.
Now that our buttery oat crust is pressed and ready, it’s time to make the sweet and tangy blueberry filling, assemble the layers, and bake these bars until golden brown and irresistibly delicious!
Step 4: Prepare the Blueberry Filling
- In a medium saucepan over medium heat, combine:
✔ 2 cups fresh or frozen blueberries
✔ ¼ cup granulated sugar
✔ 1 tbsp cornstarch
✔ 1 tbsp lemon juice
✔ ½ tsp vanilla extract - Stir and cook for 3-5 minutes, until the mixture thickens and turns syrupy.
💡 Why add lemon juice? It enhances the blueberry flavor and balances the sweetness.
🔥 Pro Tip: If using frozen blueberries, don’t thaw them before cooking—this prevents excess liquid from making the bars soggy.
5 Step: Assemble the Blueberry Oatmeal Bars
- Spread the blueberry filling evenly over the pressed crust.
- Sprinkle the remaining oat mixture evenly over the top.
👨🍳 Want a crunchier topping? Add a handful of granola or chopped nuts before baking.
Step 6: Bake the Bars
- Place the pan in the preheated 350°F (175°C) oven.
- Bake for 30-35 minutes, or until the topping is golden brown.
🔥 Want a firmer texture? Let the bars cool completely before slicing—this helps the layers set properly.
Step 7: Cool & Serve
- Allow the bars to cool in the pan for at least 1 hour before cutting.
- Serve as-is or with:
✔ A scoop of vanilla ice cream
✔ A dollop of Greek yogurt
✔ A drizzle of honey or maple syrup
💡 For a clean cut, use a sharp knife and wipe it between slices.
