Ingredients to Make Strawberry Crumble Bars

Instructions

Cookie Base

  1. Preheat oven to 350 degrees F/180 degrees C. Grease and line with parchment paper an 8 x 8 inch baking pan.
  2. Mix together the butter, sugar, flour, cinnamon and salt. Mix until it comes together like pastry. Press it into your prepared pan and bake for about 12 minutes. It should be just slightly brown at the edges. Remove from oven and leave to cool.

Strawberry Filling

  1. While the base is baking, make the strawberry filling. In a medium sized skillet set over medium heat, add the butter and sugar until it becomes foamy, about 2 – 3 minutes. Add the sliced strawberries with the cinnamon and cook down for about 10 minutes or until they are soft and fully cooked. Remove from heat.
  2. Evenly spread the strawberry filling over the shortbread base and set aside.

Crumble Topping

  1. In a medium sized mixing bowl, combine the oats, flour, brown sugar, cinnamon, baking soda, salt and butter. Mix with your fingers until it becomes crumbly.
  2. Evenly sprinkle the crumb mixture over the strawberries. Gently press down the crumble mixture with your fingers. This is to ensure it holds together after baking.
  3. Bake in your preheated 350 degree F oven for about 25 minutes. The crumble should be lightly golden brown. Remove from oven and leave to cool completely before cutting into squares.
  4. When cooled, cut into 16 equal squares and serve or store in an airtight container in the fridge.

Recipe Tips

  • Make ahead filling – You can make the filling up to about 3 days in advance and store it in an airtight container and store it in the fridge. Just make sure the filling cools completely before storing in the fridge.
  • Press crumble topping down – When you top the crumble bars before baking, make sure to gently press the crumble mixture down with your hands. This will ensure that the crumble topping will hold together after they are baked.
  • Allow to cool completely before cutting – This is very important for them to hold their shape. If you cut them before they have cooled, they will most likely fall apart.

The only substitutions I recommend for this recipe would be the filling. The base and crumble topping are perfect and have been tested many times. So, here are a few alternative fillings you may enjoy.
