Ingredients

Scale

Fruit Filling

  • 2 cups chopped strawberries
  • 2 cups chopped rhubarb
  • 3/4 cup granulated sugar
  • 2 tbsp cornstarch
  • 1 tbsp lemon juice

Crumb Mixture

  • 2 1/2 cups all-purpose flour
  • 1 cup rolled oats
  • 1 cup brown sugar
  • 1 tsp ground cinnamon
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1 cup unsalted butter, cold and cubed

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and prepare a 9×13 inch baking pan by greasing or lining it with parchment paper.
  2. Prepare Fruit Filling: In a bowl, combine the chopped strawberries, chopped rhubarb, granulated sugar, cornstarch, and lemon juice. Mix well to coat the fruit evenly and set aside.
  3. Make Crumb Mixture: In a separate large bowl, whisk together the all-purpose flour, rolled oats, brown sugar, ground cinnamon, baking powder, and salt until evenly combined.
  4. Cut in Butter: Add the cold, cubed unsalted butter to the dry ingredients. Using a pastry cutter or your fingers, cut the butter into the mixture until it resembles coarse crumbs.
  5. Form Crust: Press about two-thirds of the crumb mixture firmly and evenly into the bottom of the prepared baking pan to create the crust layer.
  6. Add Fruit Filling: Spread the prepared fruit filling evenly over the crust layer, ensuring a uniform distribution.
  7. Top with Crumbs: Sprinkle the remaining crumb mixture evenly over the fruit layer, creating a crumb topping.
  8. Bake: Bake in the preheated oven for 40 to 45 minutes, or until the crumb topping is golden brown and the fruit filling is bubbly.
  9. Cool and Slice: Allow the bars to cool completely in the pan before slicing into bars to serve.

Notes

  • For best results, use cold butter to ensure a crumbly topping.
  • You can substitute rhubarb with more strawberries if unavailable, but rhubarb adds a unique tartness.
  • Store bars in an airtight container at room temperature for up to 3 days or refrigerate for longer.
  • These bars freeze well; thaw at room temperature before serving.
