Blueberry Oatmeal Crumble Bars

🫐💙 These EASY blueberry bars are buttery and packed with blueberry flavor! They have a perfect chewy meets crispy texture from the oatmeal crust and crumble topping with soft berry filling in the middle! They take just 10 minutes of prep and then go straight into the oven. So quick to make and a crowd pleaser every time! Either fresh or frozen berries are fine.
