These Strawberry Rhubarb Crumble Bars combine the sweet flavors of strawberry with the tartness of the rhubarb, going together like chocolate and hazelnut! Definitely two flavors worth pairing.

Servings: 5

Ingredients
  

For the crumble base and top
  • 1 cup flour
  • cup granulated sugar
  • ¼ cup old fashioned oats
  • ½ tsp. baking powder
  • ¼ tsp. salt
  • ½ cup butter, cold and chopped
  • 1 egg yolk
For the fruit filling
  • ¾ cup strawberries, hulled and chopped
  • ¾ cup rhubarb, diced ¼ inch thick
  • 1 Tbsp. lemon juice
  • ¼ cup granulated sugar
  • 1 Tbsp. cornstarch

Instructions
 

  • Preheat the oven to 350°F. Grease and prepare a 9x5.5 inch loaf pan with parchment paper, allowing the paper to hang over the sides.
  • Add the flour, sugar, oats, baking powder, and salt into a medium mixing bowl and stir to combine. Add the butter and, using your fingertips, rub the butter into the flour until it resembles dried bread crumbs. Add the yolk and mix in with your fingertips. You should be able to squeeze the mixture together and form it into a light ball.
  • Pour ⅔ of the crumble mixture into the loaf pan, spread it out into an even layer, and press down with your fingertips until it forms a flat base.
  • In a separate bowl, add the strawberries, rhubarb, lemon juice, sugar, and cornstarch and stir to combine. Pour the fruit filling on top of the crumble base in the loaf pan and spread out evenly.
  • Layer the remaining crumble over the top of the fruit allowing some of the fruit to show through. Bake in the oven for 40-45 minutes until golden brown on top.
  • Remove from the oven and allow to cool in the loaf pan. Once cooled, lift the crumble bar out of the pan using the overhanging sides of the parchment paper and slice. If you prefer handheld bars, refrigerate the bars for 1-2 hours until set before slicing.

Tips to Keep in Mind

  1. When lining the loaf pan with parchment paper, ensure that the paper hangs over the sides of the pan. Once the bar is cooked and then cooled, having the paper overhang will help you pull the bars out.
  2. Make sure your butter is cold. Just like pastry, if you use warm butter, you’ll end up with a greasy base. The cold butter allows for a flaky crust which is perfect.
  3. Ensure that you use the freshest strawberries for maximum flavor. If your strawberries aren’t at their freshest, add 1-2 Tbsp. of strawberry jam/preserve to the fruit filling. This helps intensify the strawberry taste.
  4. If rhubarb is not available you can substitute with more strawberries, raspberries, or blackberries.
  5. Lots of fruit is good! When you pour the filling on top of the base it will look like a lot. As the fruit cooks it will reduce down and intensify into jammy goodness!
  6. Let the bars cool before slicing if you want beautiful, clean slices. But if you aren’t fussed about this then jump right in with a dollop of ice-cream (recommended serving suggestion!).
  7. Store these in an airtight container at room temperature for 2-3 days, or in the refrigerator for 3-4 days. They can be frozen for up to one month. Defrost by placing in the refrigerator or at room temperature to defrost completely.
