The Gluten-Free Blueberry Crumb Bars are a sweet, tender, and buttery treat that's vegan, allergy-free, and healthy! Made with a shortbread crust, layered with homemade blueberry jam, and topped with a soft buttery crumble. Like a bite of blueberry pie, these streusel-topped dessert bars are delicious served warm with a scoop of vanilla ice cream or straight from the fridge!




  1. Preheat your oven to 350°F.
  2. In a large mixing bowl, combine the gluten-free flour, quick oats, brown sugar, baking powder, cinnamon, and salt. Use a fork to mix together the mixture until combined.
  3. Add the melted vegan butter, vanilla, and lemon juice to the dry ingredients and use a fork to mix everything together until moist and combined. Set aside 3/4 cup of the crumble.
  4. Line an 8x8-inch baking pan with parchment paper before pressing in the crust mixture evenly in the bottom of the pan. Bake the bottom crust in the preheated oven for 10 minutes.
  5. Once the crust is pre-baked, add the blueberry jam to the baked bottom crust and spread it evenly over the surface. Crumble to reserved crust mixture over the top of the wet jam to cover it.
  6. Bake the bars in the oven for 35-40 minutes, until the top crumb is golden brown.
  7. Remove the bars from the oven and allow them to cool in the pan for about 10 minutes before lifting the uncut bake out of the pan with the parchment paper. Set the bars on a wire rack to cool completely or place them in the fridge/freezer to speed up the process.
  8. Using a sharp knife, cut the block of uncut bars into 9 squares or 12 rectangles.


  • Storage: Once your baked bars have cooled to room temperature, you can store them in a closed container in the fridge for up to 7 days. Enjoy them cool or reheated in the microwave.
  • Freezing: Once cooled to room temperature, slice the bars into your desired amount of servings, and wrap them in plastic and foil, before storing them in an airtight container or storage bag for up to 6 months in the freezer. Allow the bars to thaw overnight in the fridge before serving.
