Ingredients

• 4 cups fresh rhubarb, chopped into 1/2-inch pieces
• 1 1/4 cups granulated sugar, divided
• 1/4 cup cornstarch
• 1/4 cup water
• 1 teaspoon vanilla extract
• 1 cup all-purpose flour
• 1 cup sweetened shredded coconut
• 1/2 cup rolled oats
• 1/2 cup packed light brown sugar
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon salt
• 1/2 cup (1 stick) unsalted butter, cold and cut into cubes

Step-by-Step Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 13×9 inch baking dish.
2. In a large bowl, combine the chopped rhubarb with 1/4 cup of the granulated sugar. Set aside.
3. In a small saucepan, whisk together the remaining 1 cup of granulated sugar, cornstarch, and water. Cook over medium heat, stirring constantly, until the mixture thickens and bubbles. Remove from heat and stir in the vanilla extract.
4. Pour the thickened sugar mixture over the rhubarb and toss gently to coat. Pour the rhubarb mixture into the prepared baking dish and spread it out evenly.
5. In a separate medium bowl, combine the flour, shredded coconut, rolled oats, light brown sugar, cinnamon, and salt.
6. Add the cold, cubed butter to the dry ingredients. Using a pastry blender, fork, or your fingertips, cut the butter into the dry ingredients until the mixture resembles coarse crumbs with some larger pea-sized pieces.
7. Evenly sprinkle the coconut crunch topping over the rhubarb filling in the baking dish.
8. Bake for 40-50 minutes, or until the topping is golden brown and the rhubarb filling is bubbling and tender.
9. Let the crunch cool for at least 20 minutes before serving to allow the filling to set slightly.

Expert Tips / Pro Tips

For an extra crispy topping, ensure your butter is very cold when you cut it into the dry ingredients. Don’t overmix the topping; you want those buttery crumbly bits for the best texture. If your rhubarb is very fibrous, you can peel it before chopping, though this is usually not necessary for fresh, tender stalks. For a deeper flavor, consider adding a pinch of nutmeg or ginger to the topping mixture.

Variations & Substitutions

Feel free to swap out the rhubarb for other tart fruits like raspberries or strawberries, or a mix! If you don’t have rolled oats, you can use quick oats, but the texture will be slightly different. For a nuttier crunch, add 1/2 cup of chopped pecans or almonds to the topping mixture. If you prefer less sweetness, reduce the sugar in the rhubarb filling slightly.

Serving Suggestions

This Sweet and Tart Coconut Rhubarb Crunch is delightful served warm. It pairs wonderfully with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream. A drizzle of caramel sauce or a sprinkle of toasted coconut flakes can elevate it even further for a more decadent dessert experience.

Storage, Freezing & Reheating

Store any leftover Sweet and Tart Coconut Rhubarb Crunch in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days.

FAQ

Can I use frozen rhubarb?

Yes, you can use frozen rhubarb. Thaw it completely and drain off any excess liquid before using it in the recipe. You may need to add a little extra cornstarch to the filling if it seems too watery.

How do I know when the rhubarb is cooked?

The rhubarb is properly cooked when it has softened and the filling is bubbling and thick. The topping should be golden brown and slightly crisp.

Can I make this gluten-free?

To make this gluten-free, use a gluten-free all-purpose flour blend in place of the all-purpose flour. Ensure your oats are certified gluten-free as well.

Why is my rhubarb crunch watery?

A watery crunch can happen if the rhubarb releases too much liquid, especially if using frozen rhubarb. Ensure your cornstarch mixture is thick before adding it to the rhubarb and allow the crunch to cool sufficiently before serving.
