Ingredients

Scale

Fruit Base:

  • 2 cups raspberries
  • 2 cups chopped rhubarb
  • 1/4 cup granulated sugar
  • 1 tbsp lemon juice

Crust and Topping:

  • 2 cups all-purpose flour
  • 1 cup unsalted butter
  • 1/2 cup brown sugar
  • 1/4 cup rolled oats
  • 1/2 tsp salt

Binding and Flavor:

  • 2 large eggs
  • 1/3 cup cornstarch
  • 1/2 tsp vanilla extract
  • 1/4 tsp ground cinnamon
  • Powdered sugar for dusting (optional)

Instructions

  1. Preheat the oven to 350°F and line a 9×13-inch baking pan with parchment paper, allowing excess to hang over the sides for easy removal.
  2. In a medium bowl, gently combine raspberries, rhubarb, granulated sugar, and lemon juice, letting the fruits macerate while preparing the crust.
  3. Create the crust mixture by combining flour, softened butter, brown sugar, rolled oats, and salt in a large mixing bowl, working the ingredients until they form a crumbly, cohesive texture.
  4. Press approximately two-thirds of the crust mixture firmly into the prepared baking pan, creating an even, compact base layer.
  5. Whisk eggs in a separate bowl, then incorporate cornstarch, vanilla extract, and ground cinnamon until smooth and well-blended.
  6. Pour the egg mixture over the fruit, ensuring even distribution and gentle mixing to maintain fruit integrity.
  7. Sprinkle the remaining crust mixture across the top of the fruit filling, creating a rustic, textured surface.
  8. Bake for 45-50 minutes, or until the top turns golden brown and the filling appears set with minimal jiggle.
  9. Remove from the oven and allow to cool completely in the pan for at least 2 hours.
  10. Use parchment paper handles to lift the entire dessert from the pan, then slice into rectangular bars.
  11. Optionally dust with powdered sugar just before serving for an elegant finishing touch.

Notes

  • Macerate fruits beforehand to intensify their natural sweetness and create a more complex flavor profile.
  • Ensure butter is room temperature for easier mixing and a more uniform crust texture.
  • Select fresh, firm rhubarb and ripe raspberries for the most vibrant taste and optimal consistency.
  • Customize the bars by experimenting with alternative fruit combinations like strawberry-rhubarb or blueberry-rhubarb for diverse flavor experiences.
