Perfectly balanced between sweet and tart, these bars are an ideal treat for spring and summer when rhubarb is in season.

Ingredients

Base

  • ½ cup (100g) sugar
  • 2 cups (240g) all-purpose flour
  • 1 Tablespoon baking powder
  • ⅔ cup (150g) salted butter, softened at room temperature
  • 1 large egg

Rhubarb Compote

  • 4-5 long rhubarb stalks (3 ½ cups / 550g), diced
  • ⅓ cup (65g) sugar
  • 1 lemon, zest and juice
  • 2 ½ teaspoons cornstarch

Crumble Topping

  • 1 cup (100g) old-fashioned rolled oats
  • ½ cup (100g) sugar
  • 1 teaspoon vanilla sugar
  • ½ cup (100g) salted butter, melted


Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 400°F (200°C) and grease a 9-inch square baking pan thoroughly to ensure the bars don’t stick.
  2. Make the Base Dough: In a bowl, combine the sugar, all-purpose flour, and baking powder. Using your fingertips, incorporate the softened salted butter into the dry ingredients until the mixture is lump-free. Add the egg and stir well until a cohesive dough forms.
  3. Press Base into Pan: Transfer the dough into the prepared pan and press it down into an even thick layer covering the entire bottom surface.
  4. Cook Rhubarb Compote: In a saucepan over medium heat, combine diced rhubarb, sugar, lemon zest, and juice. Bring the mixture to a gentle boil. Reduce heat and add cornstarch while stirring continuously. Simmer for 5 minutes until the mixture thickens to a compote consistency.
  5. Cool and Spread Compote: Allow the rhubarb compote to cool for 5 minutes, then pour it evenly over the dough base in the pan.
  6. Prepare Crumble Topping: Mix the rolled oats, sugar, vanilla sugar, and melted butter together until combined into a crumbly texture.
  7. Sprinkle Crumble Over Compote: Evenly sprinkle the crumble mixture over the rhubarb compote layer in the pan.
  8. Bake: Place the pan in the preheated oven and bake for 20-25 minutes, or until the crumble topping turns slightly golden and crisp.
  9. Cool and Serve: Remove from oven and let the bars cool completely in the pan before cutting into squares and serving.

Notes

  • Make sure the butter for the base is softened to room temperature for easier mixing and better texture.
  • Dicing the rhubarb uniformly helps it cook evenly in the compote.
  • If you prefer a less tart taste, adjust the amount of sugar in the compote to your liking.
  • The bars are best enjoyed once fully cooled, as they hold together better.
  • Store any leftovers in an airtight container refrigerated for up to 3 days or freeze for longer storage.
