Sweet strawberries and tart rhubarb come together beneath a buttery oat crumb topping in these delicious strawberry rhubarb crumb bars.

Ingredients

Scale
  • 2 cups chopped strawberries
  • 2 cups chopped rhubarb
  • 3/4 cup granulated sugar
  • 2 tablespoons cornstarch
  • 1 tablespoon lemon juice
  • 2 1/2 cups all-purpose flour
  • 1 cup rolled oats
  • 1 cup brown sugar
  • 1 teaspoon ground cinnamon
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 cup unsalted butter, cold and cubed

Instructions

1. Preheat the oven to 350°F and prepare a 9×13-inch baking pan with parchment or light greasing.

2. In a bowl, mix strawberries, rhubarb, granulated sugar, cornstarch, and lemon juice. Set aside to allow the filling to thicken slightly.

3. In another bowl, combine flour, oats, brown sugar, cinnamon, baking powder, and salt.

4. Cut the cold butter into the dry mixture until it resembles coarse crumbs.

5. Press two-thirds of the crumb mixture into the prepared pan to form the crust.

6. Spread the strawberry rhubarb mixture evenly over the crust layer.

7. Sprinkle the remaining crumb mixture evenly on top.

8. Bake for 40–45 minutes until the topping is golden and the filling is bubbly.

9. Allow the bars to cool completely before slicing into squares.

Notes

If the fruit is very juicy, add an extra teaspoon of cornstarch to help thicken the filling.

Chilling the bars before slicing helps create clean, neat squares.

These bars freeze well and are great for gifting or make-ahead desserts.
