Ingredients:

• 1 1/2 cups all-purpose flour
• 1 cup rolled oats
• 1 cup packed brown sugar
• 1 teaspoon ground cinnamon
• 1/2 cup cold unsalted butter, cut into small pieces
• 2 cups diced rhubarb
• 2 cups diced strawberries
• 1/2 cup granulated sugar
• 3 tablespoons cornstarch

Instructions:

1. Preheat the oven to 350°F (180°C). Line a 9x13-inch baking pan with parchment paper or foil, leaving an overhang on the sides.
2. In a medium bowl, mix together the flour, oats, brown sugar, and cinnamon. Using a pastry cutter or your fingers, cut in the butter until the mixture is crumbly. Set aside 1 cup of the mixture for the topping.
3. Press the remaining mixture into the bottom of the prepared pan. Bake for 10 minutes, or until the edges are lightly golden.
4. Meanwhile, in a large saucepan, mix together the rhubarb, strawberries, granulated sugar, and cornstarch. Cook over medium heat, stirring constantly, until the mixture comes to a boil and thickens. Remove from heat.
5. Pour the strawberry-rhubarb mixture over the baked crust. Sprinkle the reserved crumble mixture over the top. Bake for an additional 25-30 minutes, or until the topping is golden and the filling is bubbly.
6. Remove from the oven and let cool completely before cutting into bars. Serve and enjoy!

Tips:

• For extra flavor, add a teaspoon of vanilla extract to the filling mixture.
