Raspberry Oatmeal Crumble Bars in 60 Min

Instructions:

1. Preheat your oven to 350°F (175°C) and line a 9x9-inch pan with parchment paper, leaving an overhang on the sides.
2. In a large bowl, whisk together the oats, flour, brown sugar, baking powder, cinnamon, and salt.
3. Add the chilled, cubed butter. Use a pastry cutter or fork to work the butter into the mixture until it resembles coarse crumbs with some pea-sized lumps remaining.
4. Firmly press approximately 2/3 of the crumble mixture into the bottom of the prepared pan using a measuring cup to ensure it is packed tight.
5. In a small saucepan over medium heat, combine raspberries, sugar, and lemon juice.
6. Stir in the cornstarch and cook for 5–8 minutes, stirring frequently, until the mixture has thickened.
7. Spread the thickened raspberry filling evenly over the pressed crust in the prepared pan.
8. Sprinkle the remaining 1/3 of the crumble mixture evenly over the top of the raspberry filling.
9. Bake for 45 minutes at 350°F (175°C) until the topping is golden brown and fragrant.
