Rhubarb Curd Layer

  • 1 ½ cups chopped rhubarb
  • ½ cup organic white sugar
  • ¼ cup water
  • ½ cup canned coconut cream *not milk, just the cream
  • 1.33 Tablespoons arrowroot powder *equal to 1 Tbsp+ 1 tsp

Shortbread Cookie Layer

  • 1 cup all purpose flour
  • ½ teaspoon salt
  • ½ teaspoon baking powder
  • ¼ cup cold vegan butter
  • ¼ cup cane sugar
  • ¼ cup brown sugar
  • 1 Tablespoon ground flaxseed *golden flax preferred
  • 1 teaspoon vanilla bean paste or vanilla extract
  • 1 Tablespoon almond milk or any plant-based milk


  • ¼ cup organic powdered sugar


First, make the shortbread layer

  • Preheat your oven to 350F. In a medium-sized bowl, whisk together flour, baking powder, and salt. Set aside.
  • In a standing mixer (or in a large bowl using an electric mixer) cream together the butter and sugar. Once creamed, add in the flax, vanilla, and nut milk and beat until well combined.
  • Add the bowl of sifted dry ingredients to the standing mixer and mix until just combined.
  • Line an 8*8 baking dish with parchment paper and press the dough into the tray so that it is even and flat. Add the dish to the oven and bake for 20 minutes.

Then, make the rhubarb curd

  • While the shortbread is cooking, make sure rhubarb curd. Begin by chopping the rhubarb and adding it to a small saucepan along with the sugar and water needed for the curd. Bring to a boil, then simmer over low heat about 5-8 minutes until the rhubarb is soft and pierceable. Make sure to stir the rhubarb constantly while cooking.
  • Add the cooked rhubarb to a blender along with the coconut cream and blend until smooth. Transfer the smooth rhubarb puree back to the saucepan and whisk in the arrowroot powder.
  • Turn on the heat and cook the rhubarb until it thickens. This will only take about 3-5 minutes. Once thick, set aside and let cool to room temperature.

Finally, bake it all together

  • Remove the shortbread from the oven and top with the vegan rhubarb curd. Add bake to the oven and bake for 15 minutes.
  • Once cooked, remove from the oven and let the rhubarb bars cool completely to room temperature. Cover and place in the fridge for at least 1-2 hours to set. Once you are ready to eat, remove and top with powdered sugar right before serving. Enjoy!


  • Rhubarb Bars can be kept in the fridge for up to 3 days in a closed container. Layer the bars between stacks of parchment paper or they will stick together and become soggy. Do not store the bars outside of the fridge.
  • Rhubarb Bars can be stored in the freezer for up to 2 months. Simply remove from the freezer and defrost on the counter before eating.
