Step‑by‑Step Instructions for Rhubarb Coconut Macaroon Tarts
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C), ensuring it's ready for baking. Lightly grease or line a muffin tin with parchment liners to make removal easy later. This step is crucial for the Rhubarb Coconut Macaroon Tarts to bake evenly, so don’t skip it!
Step 2: Make 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. Gradually mix in 1 cup of all-purpose or oat flour along with a pinch of salt, forming a crumbly dough. This crumbly texture will create a lovely crust for your tarts.
Step 3: Form the Base
Press the prepared dough firmly into the bottoms of each muffin tin cup. Ensure each crust base is evenly flattened to hold the filling without breaking apart. Set your muffin tin aside while you prepare the filling, creating a strong foundation for your delicious Rhubarb Coconut Macaroon Tarts.
Step 4: Cook the Rhubarb
In a small saucepan over medium heat, combine 1 ½ cups of chopped fresh rhubarb, 2 tablespoons of sugar, and 1 teaspoon of lemon juice. Allow the mixture to simmer for 5–7 minutes, stirring occasionally, until the rhubarb is soft and slightly thickened. Once done, remove from heat and let it cool slightly.
Step 5: Prepare the Coconut Topping
In a separate bowl, whisk 2 large egg whites until frothy. Then, stir in ½ cup of granulated sugar, ½ teaspoon of vanilla extract, a pinch of salt, and 1 ½ cups of sweetened shredded coconut until well combined. This mixture will form the crowning layer of your Rhubarb Coconut Macaroon Tarts.
Step 6: Assemble the Tarts
Spoon about a teaspoon of the cooled rhubarb mixture over each crust in the muffin tin. This layer will provide a tangy bite that beautifully complements the sweeter coconut topping. Make sure each tart gets an equal amount of rhubarb for an even taste!
Step 7: Add the Coconut Topping
Top each rhubarb layer with a generous scoop of the coconut mixture, gently pressing it down to adhere. This will create a lovely, chewy texture on top of the tart. Aim for a rounded shape that makes the tarts inviting and deliciously appealing.
Step 8: Bake to Perfection
Place the muffin tin in your preheated oven and bake for 20–25 minutes, or until the tops are golden brown and fragrant. Keep an eye on them to ensure they reach that delightful golden stage, signifying the Rhubarb Coconut Macaroon Tarts are ready to shine.
Step 9: Cool and Remove
Once baked, remove the tarts from the oven and let them cool completely in the tin. This cooling time is essential to allow the tarts to set properly. Afterward, gently lift them out using a fork or knife, ready to be enjoyed!

Expert Tips for Rhubarb Coconut Macaroon Tarts
-
Choose Fresh Rhubarb: Use fresh rhubarb for the best flavor; frozen can work, but the tarts might turn out a bit mushy.
-
Don’t Overmix: When combining ingredients for the crust, mix just until combined to ensure a tender texture in your Rhubarb Coconut Macaroon Tarts.
-
Egg Whites Peak: Whisk the egg whites until they form soft peaks for a light, airy topping; over-whisking can lead to a dry texture.
-
Cooling Time: Allow the tarts to cool completely in the tin before removing; this helps them hold their shape and prevents breakage.
-
Experiment with Sweetness: Adjust the amount of sugar in the rhubarb mixture based on its tartness; tasting as you go will lead to the best results!

Rhubarb Coconut Macaroon Tarts Recipe FAQs
How do I select the best rhubarb?
Absolutely! For the best flavor, choose rhubarb that has bright, vibrant stalks with no dark spots or wilting. The stalks should be firm and taut; avoid those with any signs of softness or decay, as they may be overly mature and less flavorful.
What is the best way to store leftover tarts?
Very! To keep your delicious Rhubarb Coconut Macaroon Tarts fresh, store them in an airtight container at room temperature for up to 2 days. If you need to keep them longer, refrigerate them for up to 5 days. Just make sure they’re fully cooled before storing.
Can I freeze these tarts? If yes, how?
Absolutely, freezing is a great option! Wrap each tart individually in plastic wrap and then place them in a freezer-safe bag or container. They can be stored in the freezer for up to 2 months. To enjoy later, simply thaw them in the fridge overnight, then warm in a 350°F (175°C) oven for about 10 minutes to restore their delightful texture.
Why are my tarts soggy?
Oh no! A soggy tart can often come from too much moisture in the filling. To avoid this, make sure to cook the rhubarb long enough to release excess moisture before adding it to the base. Additionally, pressing the crust down firmly helps create a stronger base that holds up well.
Are Rhubarb Coconut Macaroon Tarts suitable for allergies?
Great question! These tarts contain gluten and eggs, which may pose issues for those with allergies. However, you can substitute the all-purpose flour with a gluten-free blend and use aquafaba (the liquid from canned chickpeas) as an egg white replacement for a vegan option. Always consult with an allergist if unsure!
Can I adjust the sweetness of the filling?
Very much so! Feel free to taste the rhubarb mixture before adding it to the tarts. If you find it too tart for your liking, simply add more sugar to the filling—start with a tablespoon at a time until it meets your personal preference. Enjoy the process of making these tarts uniquely yours!
