Ingredients:
- For the Crust and Topping:
– 1 1/2 cups all-purpose flour
– 1/2 cup rolled oats
– 1/2 cup brown sugar, packed
– 1/2 teaspoon baking powder
– 1/4 teaspoon salt
– 1/2 cup unsalted butter, melted - For the Raspberry Filling:
– 2 cups fresh or frozen raspberries (thawed if using frozen)
– 1/2 cup granulated sugar (adjust based on sweetness)
– 2 tablespoons cornstarch
– 1 tablespoon lemon juice
– 1 teaspoon vanilla extract
Instructions:
1. Preheat your oven to 350°. Grease a 9×9-inch baking pan or line it with parchment paper for easy removal.
2. Make the Crust:
– In a mixing bowl, combine the flour, rolled oats, brown sugar, baking powder, and salt. Stir until well mixed.
– Pour in the melted butter and mix until the mixture is crumbly and resembles wet sand.
– Reserve about 1 cup of the mixture for the topping and press the remaining mixture firmly into the bottom of the prepared baking pan.
3. Prepare the Raspberry Filling:
– In a medium saucepan over medium heat, combine the raspberries, granulated sugar, cornstarch, lemon juice, and vanilla extract. Cook while gently stirring until the mixture begins to thicken, about 5-7 minutes. Remove from heat and let it cool slightly.
4. Pour the raspberry filling evenly over the crust in the baking pan. Sprinkle the reserved crumb mixture on top of the raspberry filling, distributing it evenly.
5. Bake in the preheated oven for 25-30 minutes, or until the topping is golden brown and the raspberry filling is bubbly.
6. Remove the baking pan from the oven and allow the raspberry bars to cool completely in the pan on a wire rack. Once cooled, cut into squares or bars.
