Ingredients

For Lemon Blueberry Filling

  • 2 cups Blueberries frozen
  • 1 tbsp Lemon juice
  • ¼ cup Granulated sugar
  • 2 tsp Cornstarch
  • 2 tsp Water

For Shortbread Crust

  • 1 cup Unsalted butter vegan or regular
  • ¼ cup Brown sugar
  • ¾ cup Granulated sugar
  • 2 tsp Vanilla
  • 2 tbsp Lemon juice
  • 1 tsp Salt
  • 2 cups All purpose flour

Optional: Garnish on Top

  • cup Powdered sugar

Instructions

  • Preheat the oven to 350℉.
  • For the blueberry filling, add the blueberries to a pot with the lemon juice and sugar. Heat on medium until everything begins to bubble. 
  • Add the cornstarch and water to the mixture and stir together while it continues to boil.
  • Let the blueberry filling simmer on low heat for about 5 minutes, stirring every other minute. Remove from the heat.
  • In a bowl add softened butter and whisk together until it becomes a lighter shade. Add the brown and white sugar to the butter and mix until fluffy. Add the lemon juice and vanilla extract, whisking together until combined.
  • Next add the salt and the flour to the bowl and mix until well incorporated. You should have a thick dough.
  • Add parchment paper to a 9x9 inch square baking pan. Take ¾ of the dough and press into the bottom of pan, spreading evenly. 
  • Then add a layer of the blueberry filling, spreading to cover the dough layer.
  • With the rest of the dough, crumble it on top of the blueberry filling.
  • Bake in the oven for 40-45 minutes.
  • Let cool completely before cutting and sifting powdered sugar on top if desired. Enjoy!
