Ingredients
  

For the Fruit Filling

  • 2 cups sliced strawberries Measure after removing the cores & slicing.
  • 2 cups chopped rhubarb Chopped about 1/5 – 1/4 inch slices.
  • 1/2 cup granulated sugar 100 grams.
  • 3 tablespoons cornstarch 24 grams, AKA corn flour in the UK and Australia.
  • 2 tablespoons lemon juice 30 ml, freshly squeezed.

For the Oat Crust

  • 2 cups all-purpose flour 250 grams.
  • 1 cup brown sugar 210 grams, light or dark.
  • 1/2 cup white sugar 100 grams.
  • 1 teaspoon cinnamon
  • 1/2 teaspoon salt
  • 1 3/4 cups rolled oats Large rolled oats are preferred.
  • 1 cup unsalted butter 226 grams, melted.

Instructions
 

Preparation

  • Preheat your oven to 350°F (180°C). Lightly grease a 9×13 inch (23×33 cm) baking pan or line it with parchment paper, leaving an overhang around the edges for easy removal.
  • In a mixing bowl, combine sliced strawberries, chopped rhubarb, granulated sugar, cornstarch, and lemon juice. Set aside to allow the fruit to release some juices.
  • In another bowl, whisk together flour, brown sugar, white sugar, cinnamon, and salt. Add the melted butter and rolled oats, mixing until crumbly.

Assembly and Baking

  • Press half of the oat mixture into the bottom of the prepared pan. Spread the fruit mixture evenly over it, then crumble the remaining oat mixture on top.
  • Place in the oven and bake for about 35-40 minutes, or until the top is golden brown and the fruit is bubbling.
  • Allow the bars to cool completely before cutting into squares and serving.

Notes

Serve warm with a scoop of vanilla ice cream, dust with powdered sugar for an elegant finish, or pair with fresh whipped cream or yogurt.
