Shortbread Crust and Topping

Blueberry Jam

  • 2 cups blueberries
  • 1 tbsp lemon juice
  • 2 tbsp maple syrup
  • 2 tbsp tapioca flour, or arrowroot starch
  • 2 tbsp water


  • First, preheat oven to 350 degrees Fahrenheit and line an 8 inch by 8 inch baking pan with parchment paper.
  • In a large bowl, combine shortbread crust ingredients. Stir to combine.
  • Next, press 3/4 of this mixture into the bottom of the parchment lined baking pan. Set aside the remainder.
  • Bake for 12 minutes, or until just starting to turn golden around the edges. Remove from oven.
  • Then, in a medium skillet over medium heat, add blueberry jam ingredients. Bring to a light simmer.
  • Simmer for 4 to 5 minutes, using a spatula to break apart blueberries. Simmer until thickened. Then, remove from heat.
  • Pour this blueberry jam over the baked shortbread crust. After that, crumble remaining shortbread dough over blueberries.
  • Lastly, bake for 18 to 22 minutes.
  • Remove from oven and allow to cool at least 30 minutes before slicing.
