Blueberry Banana Oat Bars

Add blueberries and maple syrup to a medium saucepan set over medium heat. Heat until the berries begin to release their liquid, about 5-15 minutes depending on whether or not they were thawed first. Bring to a boil, stirring occasionally, until berries begin to break down and thicken, about 5 -10 minutes. Use your spoon or a potato masher to break them apart further if desired.Stir in the chia seeds and vanilla, continuing to cook for another 5 minutes. Remove from heat and allow the jam to cool. It will continue to thicken the longer it sits, which is why I usually like to make it the night before I'm planning on making these bars.Preheat oven to 375F and prepare an 8x8 baking dish by lining it with a sheet of aluminum foil or parchment paper, leaving a few inches of overhang on the sides to allow for easy removal. Spray foil with cooking spray and set aside.Place 1 cup of oats in a food processor or blender, and process until they resemble a fine flour. Transfer the oat flour to a large mixing bowl, and add the remaining rolled oats and baking powder, mixing well.Add the mashed bananas, maple syrup, and vanilla extract, and mix until everything is well combined and a dough is formed.Transfer ? of the mixture into your prepared baking pan, using your fingers or a spatula to ensure that it is pressed down tightly and evenly. Spoon chia jam over the surface, and use a spatula or knife to spread it evenly, making sure to only go within ¼ of the edge to prevent the jam from burning. Sprinkle remaining oat mixture on top, breaking up bigger chunks and pressing down lightly.Bake for 30 minutes until the top turns a light golden brown. Remove from oven and allow to fully cool in pan before cutting into bars.
