Ingredients

Crumb layers

  • 1 cup all-purpose flour
  • cups rolled oats
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • ½ cup brown sugar packed
  • ¼ cup granulated sugar
  • ¾ cup butter unsalted, softened
  • 1 teaspoon vanilla extract

Filling

  • 2 cups strawberries hulled and diced
  • 2 cups rhubarb diced in small ¼ pieces
  • 1 teaspoon lemon zest
  • 1 teaspoon lemon juice freshly squeezed
  • 1 tablespoon cornstarch
  • cup sugar

Instructions

  • Prep the oven and baking dish. Preheat the oven to 350°F. Spray a 9x9-inch baking dish with cooking spray then line it with parchment paper, with the parchment paper hanging off the sides to make it easy to lift out the bars.
  • Make the fruit filling. In a mixing bowl combine all the filling ingredients together.
  • Make the crumble mixture. To a large bowl, add the flour, oats, baking powder, brown sugar, granulated sugar, salt and toss to combine. Add the butter and vanilla extract and stir using a spatula or a pastry cutter until well combined and crumbly. Set aside about a cup for the topping.
  • Assemble the bars. Press the rest of the crumb mixture into the bottom of the prepared pan. Spread the strawberries and rhubarb evenly over the crumb layer in the baking pan. Sprinkle the reserved crumb mixture over the fruit and gently press down with your hands.
  • Bake. Transfer the baking pan to the oven and bake for 45 minutes to 1 hour or until lightly browned.
  • Cool, cut and serve. Cool completely before cutting into slices and serving. Serve with vanilla ice cream if preferred.
