  • 1 1/2 160g cups old fashioned rolled oats.
  • 1 1/3 cup 175g all purpose flour.
  • 1/4 teaspoon salt.
  • 1/2 100g cup brown sugar.
  • 1/2 110g cup granulated sugar.
  • 1/2 teaspoon baking soda.
  • 3/4 cup 170g unsalted Butter, melted.
  • 1 teaspoon vanilla extract.

For the filling:

  • 1 16oz packet hulled and diced strawberries.
  • 1 1/2 cups diced fresh rhubarb.
  • 1 Tablespoon lemon juice.
  • 1/3 cup 70g granulated sugar.
  • 1 Tablespoon cornstarch.


  • Make the crumb layer:
  • Preheat oven to 350F.
  • Line a 9x9- inch baking dish with parchment paper.
  • In a bowl, combine first 6 ingredients well.
  • Add extract to the melted butter in a separate bowl and mix.
  • Pour the butter mixture on the dry ingredients and mix them all well.
  • Press 2/3 the mixture into the bottom of your baking dish to form the base.

Prepare the filling:

  • In a bowl, add strawberries, rhubarb and sugar.
  • In a small bowl dissolve cornstarch into the lemon juice the pour on top of the strawberry mixture.
  • Mix everything well together then pour it onto the base in the baking dish.
  • Sprinkle the remaining crumb mixture on top evenly.
  • Bake in the oven for 35 minutes or until top is nicely browned.
  • Cool down, cut and serve.


* Usually a 9x9 pan makes 9 servings, but I've found it really big for this recipe so I would highly recommend getting 12 servings out of this recipe, unless you are feeding hungry people.
