Strawberry Rhubarb Bars

Print Recipe

Ingredients
  

  • 3 cups all-purpose flour
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar
  • 1 teaspoon baking powder
  • 1/2 teaspoon ground cinnamon
  • 2 teaspoons pure vanilla extract
  • 1/4 cup milk

Strawberry Rhubarb Filling Ingredients

  • 2 and 1/2 cups chopped strawberries
  • 1 and 1/2 cups sliced rhubarb (half-inch pieces) If you can't find fresh, use frozen. They will cook better if you use both the strawberries and rhubarb either fresh or frozen.
  • 1/2 cup granulated sugar
  • 1 teaspoon lemon zest
  • 2 teaspoons fresh lemon juice

Instructions
 

  • Preheat oven to 350°F. To make cutting easier, I line the bottom and sides of a 9×13 pan with parchment paper, leaving an overhang on the sides to lift the finished bars out.
  • Crumble mixture for the crust and topping: Whisk the flour, sugar, baking powder, cinnamon and salt together in a large bowl. Add the cubed butter and using a pastry cutter, two forks or a food processor, cut in the butter until all the flour is coated and resembles pea-sized crumbles. I prefer to put it all in the food processor; it’s much quicker.
  • Whisk the egg, milk and vanilla together in a small bowl. Pour over the flour/ butter mixture and gently mix together.
  • You will have about six cups of the crust/crumble mixture. Set two cups aside. Pour the remaining into the prepared pan and flatten down with your hands or a flat spatula to form an even crust. It will be a little crumbly — that’s okay. Set aside.
  • Strawberry rhubarb filling: Gently mix all of the filling ingredients together. Spread over the crust. Sprinkle the remaining crumble mixture all over the filling. Sprinkle the oats on top. With the back of a large spoon or flat spatula, lightly press the topping down so it’s snug on the strawberry rhubarb layer.
  • Bake for about 42-50 minutes or until the top is lightly browned and a toothpick comes out *mostly* clean (with a few jammy strawberry/rhubarb specks). Mine take about 45 minutes. Remove from the oven and allow the bars to cool completely on a wire rack.
