Directions for Blueberry Oatmeal Bars
Let’s make these Blueberry Oatmeal Bars!
Prep the Oven and Pan
I preheat the oven to 350°F (175°C) and line an 8×8-inch baking dish with parchment paper or lightly grease it.
Mix Dry Ingredients
In a large mixing bowl, I combine 1 ½ cups rolled oats, ½ cup whole wheat flour, ¼ cup ground flaxseeds, ½ tsp baking powder, ¼ tsp salt, and ½ tsp cinnamon, stirring well.
Combine Wet Ingredients
In a medium bowl, I whisk together ⅓ cup honey or maple syrup, ½ cup unsweetened applesauce, 1 tsp vanilla extract, and 1 large egg until smooth.
Mix and Fold
I pour the wet ingredients into the dry ingredients, stirring until just combined. I gently fold in 1 ½ cups blueberries, being careful not to crush them.
Bake and Cool
I spread the batter evenly into the prepared baking dish and bake for 30–35 minutes, until the edges are golden and a toothpick inserted in the center comes out clean. I let the Blueberry Oatmeal Bars cool completely before cutting into 9 squares.
