Step‑by‑Step Instructions for Rhubarb Coconut Macaroon Tarts
Step 1: Preheat the Oven and Prepare Muffin Tin
Begin by preheating your oven to 350°F (175°C). While the oven warms up, grease a muffin tin or line it with parchment paper to ensure that your Rhubarb Coconut Macaroon Tarts come cleanly out after baking. This step is crucial to avoid any sticking, particularly because of the coconut topping.
Step 2: Make the Crust Dough
In a mixing bowl, cream together ½ cup of softened unsalted butter and ½ cup of granulated sugar until light and fluffy, which should take about 3-4 minutes of vigorous mixing. Gradually add 1 ½ cups of all-purpose flour and a pinch of salt to the mixture, stirring until you form a crumbly dough that holds together when pressed.
Step 3: Form the Crusts in Muffin Tins
Take small amounts of the dough and press them firmly into the bottom of each muffin cup, forming the crust base for your tarts. Aim for a thickness of about ¼ inch. Once all the cups are filled with crust, set the muffin tin aside as you prepare the filling and topping.
Step 4: Cook the Rhubarb Filling
In a saucepan, combine 2 cups of chopped fresh rhubarb, ½ cup of sugar, and 2 tablespoons of lemon juice over medium heat. Stir occasionally and simmer for 5-7 minutes until the rhubarb softens and breaks down into a jammy consistency. Remove from heat and set aside to cool slightly while you prepare the macaroon topping.
Step 5: Prepare the Macaroon Topping
In a clean mixing bowl, whisk 3 egg whites until frothy, about 1-2 minutes. Gradually mix in ½ cup of sugar, ½ teaspoon of vanilla extract, a pinch of salt, and 2 cups of sweetened shredded coconut, ensuring everything is well combined and the coconut is fully coated by the mixture.
Step 6: Assemble the Tarts
Carefully spoon a generous amount of the cooled rhubarb filling into each crust, filling them until just below the top edge. Next, dollop the coconut mixture over each filled crust, spreading it gently to cover the rhubarb completely. This layering creates a beautiful contrast in your Rhubarb Coconut Macaroon Tarts.
Step 7: Bake the Tarts
Place the muffin tin in the preheated oven and bake the assembled tarts for 20-25 minutes or until the tops are a golden brown color. Keep an eye on them during the last minutes to ensure they do not over-bake, as the coconut can become quite dark.
Step 8: Cool and Remove
Once baked, remove the muffin tin from the oven and allow the Rhubarb Coconut Macaroon Tarts to cool in the tin for about 10 minutes. After that, gently run a knife around the edges to loosen them, then carefully lift them out and let them cool completely on a wire rack before serving or storing.

Rhubarb Coconut Macaroon Tarts Recipe FAQs
How do I select ripe rhubarb?
When choosing rhubarb, look for firm, crisp stalks. They should have a vibrant color, preferably a mix of green and reddish-pink hues. Avoid rhubarb with wilting leaves, dark spots, or a slimy texture as these indicate overripeness or spoilage.
What’s the best way to store Rhubarb Coconut Macaroon Tarts?
To keep your tarts fresh, store them in an airtight container at room temperature for up to 3 days. For longer storage, they can be kept in the refrigerator for up to 1 week. If you plan to enjoy them later, freezing is a great option!
How should I freeze Rhubarb Coconut Macaroon Tarts?
Absolutely! To freeze your tarts, allow them to cool completely. Place them in a single layer on a baking sheet and freeze until solid. Once frozen, transfer them to an airtight container or freezer bag. They can be stored in the freezer for up to 2 months. Thaw in the fridge overnight before reheating or serving.
What do I do if my coconut topping is too dry?
If you find that your coconut topping is dry, try adding a little extra egg white or even a splash of coconut milk to the mixture. This will help moisten the coconut and make your topping richer and chewier. Always mix thoroughly to ensure the coconut absorbs the moisture.
Can I make these tarts dairy-free?
Very! To make Rhubarb Coconut Macaroon Tarts dairy-free, simply substitute the unsalted butter with a dairy-free butter alternative or coconut oil. For the egg whites, you can use aquafaba as a vegan replacement, giving the topping that lovely fluffy texture you desire.
How can I adjust for allergies?
If you're accommodating allergies, consider using gluten-free flour to replace all-purpose flour, and be cautious with shredded coconut, ensuring it is free from allergens. Always check the labels for any pre-packaged ingredients to avoid cross-contamination, especially if cooking for someone with severe allergies.
