Hong Kong style coconut tarts with a lemony twist! These coconut tarts have a delicious shredded coconut and lemon filling that sits atop a delicate and flaky shortcrust pastry. When testing the recipe, I measured most of the ingredients with a scale, and I recommend that you do the same if you have one. The volume measurements for the flour, sugar, and milk powder were measured using the spoon-and-sweep method. Enjoy these delicious treats that are not too sweet!

Equipment

18 2.75-inch to 3-inch mini tart pans, fluted or unfluted (see note 1)

Ingredients

Crust

2 cups (240g) Bob’s Red Mill all-purpose flour
1/4 cup + 2 tablespoons (44g) powdered sugar
1/4 cup (20g) milk powder, (see note 2)
11 1/2 tablespoons (160g) unsalted butter, cut into cubes
3 tablespoons (45g) whole milk

Filling

2 3/4 cups (230g) finely shredded coconut, (see note 3)
zest from 2 large lemons, about 7g to 8g
8 tablespoons (113g) unsalted butter
3/4 cup (180g/235ml) whole milk
1 1/4 cups + 2 tablespoons (165g) powdered sugar
1/4 cup (20g) milk powder
2 large eggs
1 teaspoon vanilla extract
1 teaspoon lemon extract, optional
3/4 teaspoon baking powder
1/2 teaspoon kosher salt, or 1/4 teaspoon sea salt

Instructions

Make Dough

Add the all-purpose flour, powdered sugar, milk powder, butter, and milk to a food processor. Pulse the ingredients in long pulses (about 2 seconds each), until the mixture comes together and small curds start to form (about 10 to 13 pulses). Test the mixture by grabbing a clump of the curds and squeezing them together into your hand. If the curds come together into a lump of dough, you’re done mixing. If it still feels dry and crumbly, add a tiny splash of milk and keep pulsing the mixture.
Empty the dough curds into a mixing bowl. Gather the mixture together until you form a ball of dough. Shape the dough into a disc, and chill for 45 minutes. (See note 4 if you don’t plan to work with the dough until the next day).

Start Making Filling

Right before you are about to divide and roll out the dough, start making the filling. Add the shredded coconut and lemon zest into a bowl. Rub everything together with your fingers, making sure to break up any clumps of lemon zest.
Melt the butter in the saucepan. I like to brown the butter for more flavor, but that’s optional (see note 5 for directions).
Pour the melted butter and milk over the coconut and lemon zest. Mix everything together and set aside to let the coconut hydrate.

Preheat Oven

Preheat the oven to 350ºF (175ºC) and position an oven rack to the center of the oven. Line 2 large half sheet baking pans with parchment paper (to catch any drippings from the tarts). Set the pans aside.

Roll Out Dough & Fit in Tart Tins

Divide the dough into 18 pieces of about 27 to 28 grams each. Roll each piece into balls, about 1 inch in diameter.
Lightly flour a work surface. Take one ball and flatten it slightly with the palm of your hand. Roll out the dough until you get a circle that’s about 3 1/4 to 3 1/2 inches wide. If you don’t have a ruler, you can invert one of the mini tart pins over the rolled out dough (so that the top of the tin is facing down). There should be about a 1/4-inch border of dough surrounding the tart tin. Add more flour to the work surface or the top of the dough if the dough is sticking.
Press the rolled out dough into the tart tin, making sure that the dough is flush with the tin and it reaches all the way to the top of the tin. If there’s more than a 1/4 inch of dough above the top of the tin, tuck in the excess dough.
If you are using unfluted mini tart tins, you can cut the rolled out dough with a 3.5-inch fluted cookie cutter to give the crust a bit of flourish.
After you finish rolling out the dough for 9 tins, transfer the crusts to a plate and refrigerate. Then, finish rolling out and shaping the remainder of the dough balls and chill the dough.

Finish Filling

Add the powdered sugar, milk powder, egg, vanilla extract, lemon extract (if using), baking powder, and salt to the coconut mixture. Mix until well combined.

Bake Tarts

I like to bake 9 tarts at a time to ensure that the crust and tops of the tarts bake evenly. Arrange the first batch of 9 chilled tart tins onto a baking sheet (I like to stagger them slightly. Scoop about 2 1/2 tablespoons of filling into each tin (about 44 to 45 grams). Use a mini spatula or spoon to tidy up the filling slightly and shape into a mound.
Bake the tarts for 15 minutes. Then, rotate the pan and bake for another 10 to 13 minutes, until the crusts have a rich golden color and the tops of the tarts have started to turn golden brown. Remove the tarts and let them cool in the tins for 15 to 20 minutes, until they’re cool enough to handle. The crust of these tarts are very delicate, so it’s better to let them cool before unmolding.
Bake the second batch of coconut tarts as specified above.

Removing Tarts

Invert a tart over one hand and use your other hand to carefully lift and remove the tin off the tart. Transfer the tart to a cooling rack or plate and continue unmolding the remaining tarts.
Serve the tarts slightly warm or completely cooled. Store the tarts at room temperature for 2 to 3 days or refrigerator for 5 to 6 days. See note 6 for reheating directions.

Notes

Where to Find Mini Tins: I bought a set of 25 to 30 mini tart tins online for $10, and they take up very little space in my drawer. You can also use single-use aluminum mini-tart cups for this recipe. My aunt actually washes and reuses the aluminum tart cups. The cooking time might be a few minutes less when baking with disposable aluminum cups, as they can heat a little faster.
Milk Powder: Milk powder browns and crisps up the pastry. It also gives the filling a milky flavor.
Shredded Coconut: I have a slight preference for finely shredded coconut, but shredded coconut works too and is much easier to find. Large coconut flakes are a bit too big for this recipe.
Making Dough Ahead: Method 1: If you’re planning to use the dough within 3 days, wrap the dough in plastic and refrigerate. Let the refrigerated dough sit at room temperature for 30 minutes before using so it’s easier to work with. Method 2: Divide and roll out the dough and line the tart tins before freezing. Once frozen, stack up the tins and transfer them to a freezer bag. When you are ready to bake, simply make the filling, add the filling to the frozen tart tins, and bake. There is no need to defrost the tins beforehand. However, you’ll likely need to increase the baking time by a few minutes, until the crust turns golden brown.
Browning Butter: Melt the butter in a saucepan over medium heat. Once melted, continue heating the butter until it starts bubbling feverishly. Start stirring the butter frequently to keep it from burning. Gradually, the milk solids at the bottom and sides will start to brown. Once the solids turn golden or light brown, turn off the heat and immediately pour the melted butter over the shredded coconut mixture. It usually takes me about 2 to 3 minutes to brown the butter after it has melted.
Reheating Directions: I highly recommend reheating the tarts in the oven, as it crisps up the tart crusts slightly. If you store the tarts at room temperature, reheat them at 350ºF (175ºC) for 6 to 8 minutes; reheat for 8 to 10 minutes for refrigerated tarts; reheat for 14 to 16 minutes for frozen tarts.
Baking in a Muffin Pan: I tried to bake these in a muffin pan to see if it’ll work.
