Very Berry Rhubarb Bars

Ingredients

• 2 cups all-purpose flour
• 0.5 cup packed brown sugar
• 0.5 teaspoon ground cinnamon
• 1 cup unsalted butter
• 2 cups white sugar
• 4 eggs
• 0.5 cup flour
• 0.5 teaspoon salt
• 4 cups diced rhubarb
• 2 cups sliced strawberries
• 1 cup blueberries
• 0.5 cup flour

Steps

1. Preheat the oven to 350 degrees F (175 degrees C). Grease a 13×9-inch baking dish.
2. Make crust: Mix together flour, brown sugar, and cinnamon in a large bowl until well combined. Cut butter into flour mixture until crumbs form; press into the bottom of the prepared baking dish.
3. Bake crust in the preheated oven until golden brown, about 15 minutes.
4. Make filling: Blend sugar, eggs, flour, and salt in a blender until smooth; pour into a large bowl. Fold in rhubarb, strawberries, and blueberries until incorporated, then spread onto baked crust.
5. Make topping: Mix together flour, brown sugar, oats, melted butter, and cinnamon in a medium bowl until well combined; sprinkle over fruit mixture.
6. Bake in the preheated oven until lightly browned on top and the filling has set, 45 to 50 minutes.
