(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)
Directions
Line an 8x8-inch pan with parchment paper.
In a food processor, pulse the rolled oats until they form a coarse flour. Add the soaked cashews, coconut oil, maple syrup, and vanilla extract. Process until a sticky dough forms.
Press the mixture firmly into the base of the prepared pan, forming an even crust.
In a blender, combine the chopped rhubarb, lemon juice, coconut cream, powdered sugar, lemon zest, and a pinch of salt. Blend until smooth and creamy.
Pour the rhubarb-lemon mixture over the oat crust and spread evenly to cover the base.
Refrigerate for at least 4 hours or until the bars set firmly.
Once set, cut into bars and serve chilled. Store leftovers in the refrigerator.

Variations
Sweetener Substitutes: I sometimes swap the maple syrup with agave or honey for a different flavor profile.
Add Fresh Berries: If you’re looking to add extra fruit flavor, consider blending in some fresh berries like strawberries or raspberries with the rhubarb for a new twist.
Nut-Free Version: If I’m making these bars for someone with a nut allergy, I substitute the cashews with sunflower seeds or a blend of pumpkin seeds for a crunchy texture.

FAQs
Can I use frozen rhubarb for this recipe?
Yes, I can definitely use frozen rhubarb. Just be sure to thaw and drain any excess liquid before using it in the recipe.
How long should I refrigerate the bars before serving?
I recommend refrigerating the bars for at least 4 hours, or until they’ve set firmly. If I’m in a hurry, I sometimes let them chill for a bit longer to ensure they are fully set.
Can I make these bars ahead of time?
Yes, I love making these bars ahead of time! They store really well in the fridge, so they’re perfect for preparing a day or two before serving.
Can I make a bigger batch of these bars?
Definitely! If I need more servings, I just increase the ingredients proportionally and use a larger pan, keeping in mind that the chilling time might vary slightly.
Can I substitute coconut cream for another ingredient?
If I don’t have coconut cream, I can substitute it with cashew cream or any other non-dairy cream. The coconut flavor will be less pronounced, but it will still be creamy and delicious.
