Welcome to a truly delightful and naturally sweet treat: our Gluten-Free Paleo Raspberry Rhubarb Almond Bars. These bars feature a perfectly crisp almond flour crust, generously topped with a soft, luscious almond frangipane filling, vibrant fresh raspberries, and exquisitely tart rhubarb. This simple yet sophisticated recipe is not only Paleo-friendly but also completely gluten-free and refined sugar-free, making it an ideal choice for a healthier indulgence that doesn’t compromise on flavor or texture.
Ah, Spring! The season of renewal, vibrant colors, and an incredible abundance of fresh, seasonal produce. For many, the appearance of rhubarb at local farmers’ markets is a definitive sign that warmer days are here, bringing with them a bounty of culinary inspiration. Its unique tangy flavor and stunning rosy hue make it a star ingredient, signaling the perfect time to head into the kitchen and create a bright, zesty dessert.
While I often find myself gravitating towards classics like my beloved Strawberry Rhubarb Chia Jam or the family-favorite Gluten-Free Strawberry Rhubarb Pie, I also love experimenting with new ways to showcase this incredible vegetable. The combination of rhubarb’s tartness with sweet, complementary flavors is truly magical, and these bars are no exception.
Having moved to California, I’ve noticed that fresh rhubarb isn’t as readily available as it once was during my time in Washington, where it grew in glorious abundance. However, whenever I spot those beautiful ruby-red stalks at the market, I make sure to stock up! I grab extra to experiment with immediately and freeze some to enjoy throughout the summer months. Among the many delicious rhubarb creations to emerge from my kitchen, these gluten-free raspberry rhubarb almond bars have quickly become a cherished favorite. They perfectly encapsulate the essence of spring in every bite, offering a harmonious blend of textures and flavors that will leave you wanting more.
Crafting the Perfect Gluten-Free Almond Flour Crust
The foundation of these exquisite bars is a simple yet incredibly flavorful gluten-free almond flour crust. This particular crust is designed to be distinctly almond-forward, complementing the rich frangipane-style filling beautifully. The primary ingredient is finely blanched almond flour, which provides a tender crumb and a naturally sweet, nutty base. To achieve the ideal texture, we incorporate tapioca flour, a fantastic gluten-free binder that lends both structure and a delicate lightness to the crust.
Sweetened with natural coconut sugar, this crust remains refined sugar-free, aligning perfectly with Paleo dietary guidelines. A touch of salt enhances the overall flavor profile, balancing the sweetness, while melted coconut oil binds all the dry ingredients together, ensuring a moist and cohesive crust. The best part? This simple almond crust comes together in a mere three minutes. Just a quick stir of the ingredients, a firm press into your baking pan, and it’s ready for the next layer. Minimal effort for maximum deliciousness!
Indulgent Paleo Almond Frangipane Filling
The heart of these bars is a luscious paleo version of frangipane. For those unfamiliar, frangipane is a classic European almond-flavored custard or paste, traditionally made with ground almonds, butter, sugar, and eggs. When baked, it transforms into a wonderfully gooey, fluffy, and aromatic filling, often gracing tarts, croissants, and other French patisserie delights. Our recipe reinterprets this beloved classic, making it dairy-free, refined sugar-free, and perfectly compliant with Paleo principles.
This reinvented frangipane maintains all the rich almond flavor and delightful texture of its traditional counterpart, while utilizing wholesome, natural ingredients. It forms an ideal creamy contrast to the bright, tartness of the raspberries and rhubarb. To create this exquisite filling, you’ll need a food processor or a high-powered blender, which makes the process incredibly simple.
First, you’ll combine the dry ingredients, pulverizing them into a fine powder:
- Raw almonds
- Tapioca flour
- Coconut sugar
- Salt
Once you have a smooth, flour-like consistency from these ingredients, you’ll then add the wet components to complete the frangipane:
- Solid coconut oil
- A large egg
- Pure vanilla extract
Continue to blend until all ingredients are thoroughly incorporated and a perfectly smooth, creamy paste has formed. This method ensures an even texture and a deeply infused almond flavor that will elevate your bars from simple to sublime.
Once your gluten-free almond flour crust is pressed into the pan, you’ll generously spread this dairy-free frangipane paste over it, creating a thick, luxurious layer. The next step is to beautifully adorn the filling with the fresh fruit: vibrant, tart rhubarb slices, which have been delicately tossed with lemon zest and juice for an extra burst of flavor, alongside plump, juicy raspberries. As these bars bake in the oven, a culinary transformation occurs.
The almond filling gently puffs up around the fruit, creating a soft, warm embrace. The rhubarb and raspberries soften, their juices mingling with the creamy frangipane, infusing it with their bright, tangy notes. Meanwhile, the almond flour crust firms up and turns a beautiful golden brown, forming a perfectly crisp yet tender base that holds everything together. The resulting bar is a symphony of flavors and textures, a true bite of pure Spring perfection. The natural tartness of rhubarb and raspberries is beautifully balanced by the sweet, nutty frangipane, while the crisp crust provides a delightful textural contrast. These bars are not just a dessert; they’re an experience, capturing the freshness and joy of the season.
Customizing Your Bars: Fruit Alternatives and Topping Ideas
While the combination of raspberries and rhubarb in these almond bars is undeniably delicious, this recipe is wonderfully versatile. Whether rhubarb is out of season, hard to find in your area, or you simply wish to explore different flavor profiles, feel free to substitute or combine other fruits. The almond frangipane base pairs beautifully with a wide array of sweet and tart additions.
Here are some of my favorite fruit combinations and alternatives to inspire your culinary creativity:
- Classic Strawberries & Rhubarb: A timeless duo, the sweetness of strawberries beautifully complements rhubarb’s tartness.
- Plump Blueberries: For a burst of classic berry sweetness and a stunning color, blueberries are an excellent choice.
- Dark Blackberries: Offering a slightly deeper, more intense berry flavor, blackberries create a sophisticated bar.
- Any Combination of Your Favorite Berries: Feel free to mix and match! Strawberries, blueberries, raspberries, and blackberries together create a vibrant berry medley.
- Sweet Peach Slices (or any other stone fruit): During peak summer, thinly sliced peaches, nectarines, or plums would be absolutely divine. Their juicy sweetness pairs wonderfully with the nutty frangipane.
- Nectarine & Blackberry: A delightful combination of juicy, sweet nectarines with the slight tang of blackberries.
For an elegant finishing touch, I sometimes sprinkle a tiny bit of powdered sugar over the cooled bars. This is purely for aesthetics and enhances their visual appeal. If you’re committed to avoiding all refined sugars, you can certainly omit this step without affecting the taste whatsoever. Given that it’s only about a tablespoon of powdered sugar for the entire pan of bars, it’s a minor addition that won’t significantly impact the overall nutritional profile. Rest assured, these bars are beautiful and delicious with or without the delicate dusting of powdered sugar!

For the topping
- ¾ cup 110g unsalted raw almonds
- 1 tablespoon tapioca flour
- ¼ teaspoon kosher salt

- 1 cup chopped rhubarb, cut into 1″ thick slices
- 1 cup fresh raspberries

Instructions
-
Preheat oven to 350°F (175°C) and line an 8×8” square pan with parchment paper. Lightly grease the parchment paper with nonstick cooking spray.
-
In a medium mixing bowl, combine the almond flour, tapioca flour, coconut sugar, salt, and melted coconut oil. Stir until all ingredients are fully combined and no dry flour remains. Press this mixture evenly into the bottom of the prepared pan to form the crust.
-
In a food processor or high-powered blender, grind the raw almonds, tapioca flour, salt, and coconut sugar until they form a fine powder. Add the solid coconut oil and process until it is fully incorporated and no longer visible. Finally, add the egg and vanilla extract, blending until a completely smooth and uniform paste is formed. Carefully spread this almond frangipane filling evenly over the pressed crust.
-
In a separate small bowl, gently toss the chopped rhubarb slices and fresh raspberries with the lemon zest and lemon juice. Evenly spread this fruit mixture over the almond frangipane layer in the pan.
-
Bake for 40 minutes, or until the frangipane filling is set and a skewer inserted into the center comes out clean. The top should be lightly golden.
-
Allow the bars to cool completely in the pan on a wire rack before attempting to cut them into squares. This ensures they set properly and are easy to handle.
-
Store any leftover bars in an airtight container in the refrigerator for optimal freshness.
