Every year my mom gives me giant bags of rhubarb from her rhubarb plant that continuously gets larger and larger every year. These Strawberry Rhubarb Bars are my FAVORITE classic early summer dessert to use up that rhubarb! They are tart, sweet, buttery, and so irresistible.

I love to take these to a family party in the summer (like Memorial Day) or just enjoy at home for a weeknight treat with my husband. They’re even better warm with a little vanilla ice cream on top… yum!

What’s the difference between red & green rhubarb?

Red rhubarb (which characteristically has red hues to it’s stalks) tends to be slightly sweeter. On the other hand, green rhubarb (which has green stalks with a pink hue) is more tart. Both rhubarb types are great in this recipe. The sugar and strawberries balance the tartness if you are using green rhubarb. If you use red, your bars may be subtly sweeter.

How to Make Vegan Strawberry Rhubarb Bars

Combine Strawberries & Rhubarb

Preheat the oven to 350 F. Butter or oil an 8×8 glass pan (or use parchment paper).

Filling: In a medium bowl add your sliced strawberries, diced rhubarb, lemon juice, cornstarch, white sugar, and maple syrup. Mix until combined.

Combine Dry Ingredients

Base & Topping: In a large bowl add your flour, old fashioned oats, baking soda, salt, white sugar, and brown sugar. Whisk until combined.

Add Wet to Dry

Add your melted coconut oil and vanilla extract and mix until you have a soft dough.

Assemble

Pour 2/3 of the flour/oat mixture into your pan and press down firmly and evenly with the back of a spoon.

Pour your fruit filling on top evenly. Crumble the rest of the flour/oat mixture over the fruit.

Bake, Cool, & Enjoy!

Bake for 45-55 minutes or until the top has become slightly browned and crisp.

Let cool for at least 20 minutes before cutting into bars. Serve with vanilla ice cream for the best treat!

How do you store leftover bars?

Let them cool first and then cut them into bars and store then in an airtight container on the counter. Enjoy them within 3 days.

*FYI- If you store them in the fridge, the top is more likely to get mushy.

Can I use frozen fruit for these bars?

Frozen fruit can work in this recipe, but make sure you thaw and drain off the extra liquid before adding.

Can I substitute other fruits for strawberries in this recipe?

Yes, you can substitute other fruits like raspberries, blueberries, blackberries, or cherries!


Pro Tips


  • Allow the bars to cool completely before cutting to ensure clean slices.
  • Serve with a dollop of whipped cream or a scoop of vanilla ice cream. I personally love So Delicious Very Vanilla Cashewmilk Frozen Dessert!
  • Use fresh rhubarb and strawberries for the best flavor and texture.
