Directions: Rhubarb Coconut Bars
1. Preheat the oven to 350°F (175°C) and grease a 9×9 inch baking pan. This temperature will create the perfect environment for your bars to bake evenly, giving them a nice, golden top.
2. Combine flour, unsweetened shredded coconut, granulated sugar, melted butter, and salt in a mixing bowl. Mix until crumbly for a delicious crust that will hold all the sweet filling together beautifully.
3. Press the mixture firmly into the bottom of the prepared baking pan. Ensure it’s evenly distributed to create a solid base for your tangy rhubarb filling.
For the Filling:
4. Mix together chopped rhubarb, granulated sugar, cornstarch, vanilla extract, and egg in a separate bowl. Stir well until everything is combined; this will help balance the tanginess of the rhubarb with sweetness.
5. Pour the rhubarb filling over the crust in the baking pan. Spread it evenly to ensure each bite of your Rhubarb Coconut Bars is packed with flavor.
6. Bake in the preheated oven for 30 minutes or until the filling is set and the top is lightly golden. You’ll know it’s done when it looks firm and inviting!

Tips for the Best Rhubarb Coconut Bars
- Butter Temperature: Ensure your melted butter isn’t too hot when mixing; this can make the crust greasy instead of chewy.
- Flour Measurement: Spoon and level your flour to avoid packing it too tightly, which could lead to a dense crust.
- Rhubarb Prep: Use fresh rhubarb for the best flavor; older stalks may be too fibrous and can alter the texture of your filling.
- Cornstarch Importance: Don’t skip the cornstarch! It helps thicken the filling and prevents it from being runny, ensuring perfect Rhubarb Coconut Bars.
- Cooling Time: Allow the bars to cool completely before cutting; this helps them set properly and makes slicing easier.
How to Store and Freeze Rhubarb Coconut Bars

- Room Temperature: Keep your Rhubarb Coconut Bars in an airtight container for up to 3 days. They’ll remain chewy and delicious!
- Fridge: For longer freshness, store the bars in the fridge for up to a week. Just make sure they’re well-wrapped to prevent them from drying out.
- Freezer: Freeze individual bars wrapped in plastic wrap for up to 3 months. Thaw in the fridge overnight before enjoying them again.

Rhubarb Coconut Bars Your Way
Feel free to let your creativity shine and customize these delightful treats to match your taste!
- Gluten-Free: Substitute all-purpose flour with a 1:1 gluten-free baking blend for a gluten-free version. This will keep the texture chewy while making it suitable for those with gluten sensitivities.
- Nutty Delight: Add 1/4 cup of finely chopped nuts, like almonds or pecans, to the crust for an extra crunch. The nutty flavor pairs beautifully with the tangy rhubarb and sweet coconut.
- Coconut Cream: Replace unsalted butter with coconut oil to enhance the coconut flavor in the bars. This twist adds a rich, tropical essence that makes each bite even more luscious.
- Zesty Lemon: Mix in the zest of one lemon into the filling for a refreshing citrus kick. The bright lemon notes elevate the tanginess of the rhubarb, creating a vibrant flavor profile.
- Berry Boost: Toss in 1/2 cup of fresh berries, such as strawberries or blueberries, alongside the rhubarb for added sweetness and color. Each bar will burst with juicy fruit, making them even more irresistible.
- Spicy Kick: Add a pinch of cayenne pepper or chili powder to the crust for a surprising hint of heat. This unexpected twist will awaken your taste buds and add depth to the overall flavor.
- Vegan Option: Swap out the egg for a flaxseed meal mixture (1 tablespoon flaxseed meal + 3 tablespoons water) for a plant-based alternative. These bars will still be deliciously chewy while catering to vegan diets.

Rhubarb Coconut Bars Questions Answered
What type of rhubarb should I use for these bars?
You’ll want to use fresh, vibrant rhubarb stalks for the best flavor and texture. Look for firm, crisp stalks with a bright pink or red hue, as they indicate ripeness and sweetness. If you can’t find fresh rhubarb, frozen rhubarb works well too—just make sure to thaw and drain any excess moisture before using it.
Can I substitute the all-purpose flour in this recipe?
Absolutely! If you’re looking for a gluten-free option, you can use a 1: 1 gluten-free flour blend. Almond flour also adds a lovely nutty flavor; just remember that it will change the texture slightly, making it a bit more tender and crumbly.
How should I store leftover Rhubarb Coconut Bars?
To keep your bars fresh, store them in an airtight container at room temperature for up to 3 days. If you need to keep them longer, refrigerate them for up to a week. Just be aware that refrigeration may alter their chewy texture slightly.
Can I freeze these Rhubarb Coconut Bars?
Yes, you can freeze these bars! Wrap them tightly in plastic wrap or aluminum foil and place them in a freezer-safe container. They will keep well for up to 3 months. When you’re ready to enjoy them again, simply let them thaw at room temperature or pop them in the fridge overnight.
What can I do if my filling isn’t setting properly?
If your filling seems too runny after baking, it might not have cooked long enough. Make sure your oven is fully preheated to 350°F (175°C) before baking and check for doneness at the 30-minute mark. The top should be lightly golden and the filling set—it shouldn’t jiggle when gently shaken.
How many servings does this recipe yield?
This delightful recipe makes about 4 generous servings. Each bar is approximately 180 calories, making them a satisfying treat without being overly indulgent! Feel free to double the recipe if you’re hosting friends or family; simply use a larger pan and adjust the baking time accordingly.
