Step‑by‑Step Instructions for Rhubarb Coconut Macaroon Tarts
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). As the oven warms up, take a moment to lightly grease a muffin tin or line it with parchment liners. This ensures that your Rhubarb Coconut Macaroon Tarts will release easily once baked, giving you perfectly shaped delights to enjoy.
Step 2: Prepare the Crust
In a mixing bowl, cream together ½ cup of softened unsalted butter and ¼ cup of granulated sugar until the mixture is light and fluffy, which should take about 3-4 minutes. Gradually mix in 1 cup of flour and a pinch of salt, stirring until the ingredients combine into a crumbly dough. This dough will serve as the delicious base for your tarts.
Step 3: Form the Crust
Press the crumbly dough firmly into the bottoms of the muffin tin cups, creating an even layer that forms the crust base. Use your fingers or the back of a spoon to ensure the crust is well-packed. Let the crusts rest while you prepare the tangy rhubarb filling.
Step 4: Cook the Rhubarb Filling
In a small saucepan, combine 1 ½ cups of chopped fresh rhubarb with 2 tablespoons of granulated sugar and 1 teaspoon of lemon juice. Place the saucepan over medium heat and simmer for 5-7 minutes. Stir occasionally until the rhubarb softens and the mixture thickens slightly. Once done, remove from heat and allow it to cool slightly.
Step 5: Make the Coconut Topping
In a separate bowl, whisk together two large egg whites until frothy and slightly stiff. Then add in ½ cup of granulated sugar, ½ teaspoon of vanilla extract, and a pinch of salt. Gently fold in 1 ½ cups of sweetened shredded coconut until everything is evenly combined. This will create a light, fluffy topping for your Rhubarb Coconut Macaroon Tarts.
Step 6: Assemble the Tarts
Spoon about a teaspoon of the prepared rhubarb filling over each crust in the muffin tin. Be sure to distribute it evenly among all cups. Next, take a generous scoop of the coconut mixture and top each tart, gently pressing it down to adhere. This layering creates a delightful texture and flavor contrast in your tarts.
Step 7: Bake the Tarts
Place the muffin tin in the preheated oven and bake your Rhubarb Coconut Macaroon Tarts for 20-25 minutes. Keep an eye on them; they are ready when the tops are golden brown and the coconut is slightly toasted. Your kitchen will fill with a wonderful aroma, signaling that a delicious treat is on the way.
Step 8: Cool and Enjoy
Once baked, remove the tarts from the oven and let them cool completely in the tin. This cooling step is important for them to set perfectly. After they are cool, gently remove the tarts from the muffin tin. Now, your Rhubarb Coconut Macaroon Tarts are ready to be served and enjoyed!
Make Ahead Options
These Rhubarb Coconut Macaroon Tarts are perfect for busy cooks looking to streamline their dessert planning! You can prepare the crust and rhubarb filling up to 24 hours in advance—simply keep them covered in the refrigerator to maintain freshness. As for the coconut topping, it can be mixed and stored separately in an airtight container for up to 3 days without losing its delightful texture. When you’re ready to enjoy the tarts, simply assemble by spooning the rhubarb filling and topping with coconut, then bake as directed. This convenient prep ensures you’ll have delicious, home-baked treats with minimal effort when the craving strikes!

Rhubarb Coconut Macaroon Tarts Recipe FAQs
What should I look for when selecting fresh rhubarb?
Absolutely! When picking rhubarb, look for stalks that are firm and bright pink to red in color. Avoid any that show dark spots or are limp—these are signs of age and may taste overly tart or tough.
How should I store my Rhubarb Coconut Macaroon Tarts?
You can keep the tarts in an airtight container at room temperature for up to 2 days, but for longer freshness, refrigerate them. If you choose to go this route, they can last up to 5 days, served cold or at room temperature, depending on your preference.
Can I freeze Rhubarb Coconut Macaroon Tarts? How?
Absolutely! To freeze your tarts, allow them to cool completely. Then, place them in an airtight container, separating layers with parchment paper to prevent sticking. They’ll stay fresh for up to 2 months. When you're ready to enjoy them, simply thaw overnight in the fridge and reheat for about 10 minutes in a 350°F (175°C) oven.
How do I adjust the recipe for dietary allergies?
Very! If you're catering to gluten-free diets, swap in oat flour for all-purpose flour as it works beautifully. For nut allergies, rest assured, there are no nuts in this recipe; however, always check packaging for cross-contamination. If egg allergies are a concern, you could experiment with aquafaba as a substitute for the egg whites, using 3 tablespoons per egg white.
What’s the best way to avoid soggy crusts?
Keep a close eye on the baking time and avoid overbaking, but also, make sure that your crust is firmly pressed into the muffin tin base. A pre-baked crust can help, too. If you're concerned about sogginess, bake the crust for about 5-7 minutes before adding the filling and topping—this will create a sturdier base for your Rhubarb Coconut Macaroon Tarts!
