- 2 Tablespoons fresh lemon juice

How to Make Blueberry Oatmeal Bars From Scratch
Preparing the Crust and Crumble Topping
Start by preheating your oven to 350°F. Line your metal pan with parchment paper for easy removal later. In a large bowl, mix together melted butter, flour, oats, brown sugar, cinnamon, and salt. Stir until the mixture resembles large, sandy clumps.
Creating the Delicious Blueberry Layer
In another bowl, toss the fresh blueberries with granulated sugar, lemon juice, and cornstarch. This mixture brings out the berries’ natural sweetness and creates a delightful filling.
Assembling and Baking Your Bars
Press the majority of the crumb mixture firmly into the bottom of the pan to form an even crust. Spread the blueberry mixture evenly over the crust, and then sprinkle the reserved crumble on top. Bake in the preheated oven for 50-55 minutes, checking at the 15-minute mark. If the top browns too quickly, cover it with foil.
Cooling and Slicing for Perfect Portions
Once baked, the bars should be golden brown with bubbling blueberries. Cool them in the pan for 30-60 minutes. Use the parchment paper to lift the bars out and let them cool completely before slicing into squares.
Tips for the Best Blueberry Oatmeal Bars
Ingredient Substitutions and Variations
Feel free to substitute vegan butter or coconut oil for the unsalted butter. You can also use gluten-free flour and oats, or coconut sugar instead of brown sugar. For a fun twist, try adding fresh peaches or strawberries to the blueberry layer!
Serving Suggestions
For an indulgent treat, serve the warm bars with a scoop of vanilla ice cream. They pair wonderfully with a dollop of Greek yogurt or a drizzle of peanut butter for added protein.
Storing and Freezing Your Bars
Store any leftovers in an airtight container in the refrigerator for up to 5 days. To freeze, cut the bars into squares, wrap each individually in plastic wrap, and place them in a freezer bag. Thaw overnight in the fridge and warm them in the microwave before enjoying.
