Paleo Blueberry Pistachio Bars

1 Preheat your oven to 350 degrees F. Line an 9x9 baking dish with parchment paper and spray lightly with cooking spray.
2 In a small bowl, combine all the dry ingredients except the blueberries and pistachios.
3 In a standing mixer, beat together the wet ingredients until well combined.
4 Once combined, slowly add the dry ingredients to the mixer and beat until just combined ~ about a minute.
5 Using a hand utensil, stir in the blueberries and pistachios (reserving a few for the top).
6 Pour the batter into the prepared baking dish, top with reserved pistachios and bake for 25-30 minutes.
7 Let cool completely before removing the bars from their baking dish.
8 Cut into 12-16 bars and enjoy!
