Strawberry Paleo Rhubarb Bars Ingredients
For the Crust
- Almond Flour – A primary ingredient that gives these bars a delightful crumbly texture; Coconut flour can be used in smaller amounts, but adjust liquid accordingly.
- Coconut Flour – Adds additional texture and nutrition; it’s crucial to the recipe for the best consistency.
- Salt – Enhances overall flavor; feel free to use sea salt or Himalayan salt as substitutes.
- Vanilla Extract – Infuses warmth and sweetness into the crust; for a richer flavor, consider vanilla bean paste.
- Maple Syrup – Acts as the natural sweetener while bringing moisture; honey or agave syrup can be alternatives, but they may slightly alter the taste.
- Coconut Oil – Binds the crust ingredients together while providing healthy fats; use it melted, or swap for neutral oils like avocado oil.
For the Filling
- Strawberries – Offers natural sweetness and vibrant flavor; must be hulled and sliced before use.
- Rhubarb – Brings tartness and texture; ensure it’s fresh or thawed if using frozen. This ingredient is essential for that signature tart flavor.
- Lemon Juice – Brightens the filling and balances the sweetness of the fruits; lime juice can be a refreshing alternative.
- Ground Ginger – Adds a warm spice complement; grated fresh ginger can enhance the flavor even more.
- Tapioca Starch – Thickens the fruit filling, preventing a soggy base; make sure to mix with water to keep it lump-free. If necessary, cornstarch can serve as a substitute.
For the Topping
- Cashews – Provide a delicious crunch; chop them roughly for varied texture or swap for pecans or walnuts.
- Coconut Butter – Creates a rich, smooth glaze; melt until fully liquefied for the best results, or consider almond butter for a different nutty flavor.
Step-by-Step Instructions for Strawberry Rhubarb Paleo Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). Prepare a 9×13 inch baking dish by lining it with parchment paper, allowing some overhang for easy removal once baked. This setup will ensure your Strawberry Rhubarb Paleo Bars come out perfectly and are easy to handle after baking.
Step 2: Prepare the Crust
In a mixing bowl, combine almond flour, coconut flour, salt, vanilla extract, maple syrup, and melted coconut oil. Stir until the mixture becomes crumbly yet cohesive, resembling coarse sand. Press about three-quarters of this mixture evenly into the prepared baking dish, creating a solid base. Bake for 10-12 minutes until it turns lightly golden on the edges and fragrant.
Step 3: Cook the Filling
While the crust bakes, prepare the fruit filling by placing sliced strawberries and rhubarb into a medium saucepan. Add in the lemon juice, maple syrup, and a pinch of salt, and stir well. Cook over medium heat, letting the mixture simmer for about 7 minutes until the fruit softens and begins to break down, creating a beautiful sauce filled with flavor.
Step 4: Thicken the Filling
In a small bowl, whisk together tapioca starch with a couple of tablespoons of water until smooth. Add this slurry into the simmering fruit mixture, stirring continuously. Cook for an additional 1-2 minutes, allowing it to thicken into a luscious filling for your Strawberry Rhubarb Paleo Bars. Remove from heat and let it cool slightly, which will help prevent a soggy crust.
Step 5: Assemble the Bars
After the crust has baked and cooled slightly, carefully spread the warm fruit filling over it, ensuring an even layer. Crumble the remaining dough mixture over the top, combining it with roughly chopped cashews for added crunch. Bake the assembled bars for about 20 minutes until the topping is golden brown and the filling is bubbly and aromatic.
Step 6: Make the Glaze
While the bars are baking, prepare a delicious glaze by mixing melted coconut butter, maple syrup, vanilla extract, and lemon juice in a small bowl until smooth. This glaze will add a delightful finishing touch to your Strawberry Rhubarb Paleo Bars.
Step 7: Cool & Slice the Bars
Once baked, remove the bars from the oven and let them cool in the pan for about 2 hours. This cooling time allows the bars to set properly, making them easier to cut. Once cooled, lift the bars out using the parchment paper, slice into squares, and enjoy.

Expert Tips for Strawberry Rhubarb Bars
Bake for Texture: Ensure the crust is baked until just golden. This keeps it firm and prevents a soggy base that can ruin your bars.
Cool Filling First: Allow the fruit filling to cool to room temperature before spreading it on the crust. This prevents sogginess and ensures the layers hold together beautifully.
Crumble Topping Variation: For an appealing texture, crumble the topping in varied sizes. This enhances the crunch and browns nicely during baking.
Smooth Glaze Magic: Melt the coconut butter until completely smooth to create a lovely glaze. Drizzling it over warm bars helps it spread evenly and look gorgeous.
Fruit Freshness Counts: Use fresh rhubarb and strawberries for the best flavors. If you’re using frozen, make sure they are fully thawed and drained to achieve the right consistency for your filling.
Storage Tips for Strawberry Rhubarb Paleo Bars
Fridge: Store your bars in an airtight container in the fridge for up to 5 days. This will keep them fresh and delicious while maintaining their lovely texture.
Freezer: For longer storage, wrap individual bars in parchment paper and place them in a freezer-safe container. They can be frozen for up to 3 months.
Thawing: To enjoy a bar from the freezer, simply thaw it overnight in the fridge before serving. This ensures the flavor and consistency of your Strawberry Rhubarb Paleo Bars remain intact.
Reheating: If you prefer them warm, gently reheat in the microwave for a few seconds or briefly in the oven at a low temperature for that freshly baked feel.

Strawberry Paleo Rhubarb Bars Recipe FAQs
What should I look for when selecting strawberries and rhubarb?
Absolutely! When choosing strawberries, look for bright red, plump berries with a fresh green stem—avoid any with soft spots or mold. As for rhubarb, it should be firm and crisp; look for vibrant red stalks free of dark spots. If you notice softer, duller stalks, it’s best to skip them.
How should I store my Strawberry Paleo Rhubarb Bars?
You can store these delicious bars in an airtight container in the fridge for up to 5 days; just make sure they’re completely cooled first. For longer storage, I often recommend wrapping individual bars in parchment paper, then placing them in a freezer-safe container. They can be frozen for up to 3 months!
Can I freeze these dessert bars? If so, how?
Very! To freeze your Strawberry Paleo Rhubarb Bars, first, allow them to cool completely. Next, cut them into squares and wrap each piece in parchment paper. Then, place the wrapped bars into a freezer-safe container or a resealable plastic bag, and make sure to remove as much air as possible. When you’re ready to enjoy, just thaw them overnight in the refrigerator or at room temperature.
What if my bars turn out soggy? What can I do?
If your bars end up soggy, it might be due to the fruit filling not cooling properly before assembly or the filling being too juicy. To remedy this, make sure to cool the fruit filling until it’s just warm before spreading it on the crust—this helps prevent a soggy layer. Additionally, if you find your filling is too runny, you can add a bit more tapioca starch mixed with water while cooking to thicken it up before using it.
Are these bars safe for someone with nut allergies?
No worries! If anyone has nut allergies, I suggest using sunflower seed flour as a perfect substitute for almond flour to maintain that lovely crumble. While cashews add crunch in the topping, you could swap them out for seeds like pumpkin or sunflower seeds, which add a delightful texture without any nuts. Always double-check your ingredient labels just to be safe!
Can I substitute the maple syrup in this recipe?
Absolutely! If you need an alternative to maple syrup, honey or agave syrup can work well; however, keep in mind they may slightly alter the flavor profile of the bars. If you’re vegan, make sure to use agave, as honey is not plant-based. Just remember to adjust the sweetness to your taste, as these substitutions can vary in sweetness levels.
