Blueberry Tartlets

These blueberry tartlets have a sweet, buttery crust and are filled with an easy homemade blueberry sauce. You can make the tart shells with all-purpose or gluten-free flour, and the filling can be sweetened with granulated sugar or maple syrup.

Ingredients

I used almond extract in my filling, but you can use lemon extract and zest as an alternative if you prefer. Start with 1 tablespoon of zest. Taste it before adding the fresh blueberries to the sauce, and add up to another tablespoon of zest if needed.

Fresh vs frozen blueberries

To make the blueberry filling, you make blueberry sauce and then stir in fresh blueberries.

You can use either fresh or frozen blueberries when making the blueberry sauce. But the blueberries you stir into the sauce need to be fresh.

Frozen ones don’t have a pleasant texture. They’re great in baked goods and smoothies, but not to eat without cooking or blending.

They’d also release a lot of liquid, whereas fresh blueberries won’t release any as they stay whole in the filling.

Maple syrup option

Blueberries and maple syrup are a magical combination.

If using maple syrup, you may want to omit the almond extract.

I meant to test out the maple syrup + almond extract combination, but I forgot to add the extract. After making this sauce 7 times in a week, I couldn’t bring myself to go buy even more blueberries.

Perhaps it’s fantastic, but blueberry + maple flavor + almond extract sounds a little strange to me. Just remove a small amount of the filling, add a teeny tiny amount of almond extract, and see how you like it before adding the extract to the rest of the blueberry filling.

Can I use other fruit?

A different type of fruit would require a different amount of sugar. And you’d need a slightly different amount of water and cornstarch.

You can definitely experiment, but keep in mind that you’d probably have to adjust those 2 things.

Tart crust

I went through an absurd number of tart crust recipes before realizing I should just try one from King Arthur Flour.

It was perfect. But I made a few changes.

They write that chilling the dough is optional, but I think it’s necessary. The dough is much easier to work with if you chill it.

They also use pie weights and dock the crust (so prick holes all over the bottom with a fork).

None of that is necessary for these tartlets.

And I also tested out a gluten-free option!

All of the other tart crust recipes I tried were too crumbly, not sweet enough, tasted like nothing or were cakey or got soggy after filling.

These were perfect and were so tasty that we ate a few unfilled. Hands down the best tart crust I’ve ever had.

If you look at their recipe, it has a strangely low rating. So I read the reviews before making it for the first time. And I can say with certainty that you can ignore the rating and reviews. ;)

One person poured rice directly over the unbaked crust and then said that the rice stuck to the crust. Another claimed that the gram measurements were wrong. They said they always weigh their flour, and 133 grams is less than 1 cup (note: 1 cup of flour = 120-125 grams). So if they can’t measure flour properly, it’s not a surprise it didn’t come out.

Some said the dough was too dry, some said it was too wet. I think there’s a bit of user error going on there.

In conclusion, this tart crust is amazing. And ignore the reviews.

Blueberry filling

There isn’t much to say about this filling that I haven’t already said.

But here’s an overview of how you make it.

Mini tart pans

I used these Wilton Perfect Result 4.75″ (12 cm) Tart Pans. They come in a 6-pack.

I’ve had this set for 10 years, and they’re still in perfect condition. Just like with other tart pans, you should remove the tart from the pan to cut it. Don’t cut the mini tarts in the pans or you’ll scratch up the pans.

If you can’t find those, make sure to get mini tart pans with removable bottoms so that the shells are easy to remove.

Can I make 5 instead of 4 tarts?

This is what I originally did. It works, but I preferred the shells to be a bit thicker and to have more blueberry filling.

Can I roll it out instead of pressing it in?

The original recipe says you can, but I think it’s much easier and quicker just to press it in.

Do I need to use pie weights?

Not when using this recipe for mini tart pans! I’ve also used this recipe for a 9″ tart, and for that, you do need pie weights.

The crust slumped down without them.

Make ahead and how to freeze

These are great to make in advance!

The dough

You can prepare the tart dough up to 3 days in advance. Or you can freeze it for up to 3 months.

Wrap the disc tightly in plastic wrap and then place it in a Ziploc. Thaw the dough overnight in the fridge before using. Do not use the microwave to thaw it!

Unbaked tart shells

You can press the dough into the tart pans, cover them up properly, and refrigerate for up to 3 days.

Baked tart shells

Once they’re baked, you can put them in an airtight container and store at room temperature for up to 3 days or refrigerate for 5 days.

The filling

The blueberry filling can be made up to 3 days in advance and stored in an airtight container in the refrigerator. If it’s too firm after chilling to transfer it to the tart shells, you can gently warm it over low heat. Stir constantly – but very carefully so you don’t smush the blueberries!

How to store

Once you’ve filled the tarts, they can be refrigerated for up to 3 days. They amazingly don’t get soggy (thanks to the great crust recipe!), and I think I even prefer them on the 2nd day.

The crust sucks up just a little bit of moisture from the filling, making the tarts completely irresistible.

Can I freeze them?

You can freeze the crusts, as I wrote above, but you won’t want to freeze the filling. Because (as I also wrote above) the blueberries won’t have the right texture once defrosted.

You might be able to make just the sauce, freeze, defrost, and then stir in the fresh blueberries. But I haven’t tried it, so I can’t say for sure.

Gluten-free option

So far, I’ve only tried the crust with King Arthur Flour Gluten-free Measure for Measure Flour.

It’s just as delicious as the all-purpose flour version.

That’s it. I hope you’ll enjoy these blueberry tartlets! I’d love for you to leave a comment down below if you try them out. :) Thanks!

Ingredients

For the crust:

• ▢ 1 1/4 cups (150 grams) flour see notes
• ▢ 1/4 cup (50 grams) granulated sugar
• ▢ 1/2 teaspoon salt
• ▢ 1/2 cup (113 grams) unsalted butter cold, cut into 1/2" cubes
• ▢ 1 large egg yolk
• ▢ 1 teaspoon vanilla extract
• ▢ 1-2 tablespoons milk see notes

For the filling:

• ▢ 1 1/2 cups (225 grams) fresh or frozen blueberries
• ▢ 2 cups (300 grams) fresh blueberries
• ▢ 1/4 to 1/3 cup (60-80 ml) water
• ▢ 2/3 cup (133 grams) granulated sugar or 2/3 cup (213 grams) maple syrup
• ▢ pinch salt
• ▢ 1 1/2 tablespoons cornstarch + 2 tablespoons water
• ▢ 1/2 teaspoon vanilla extract
• ▢ 1 teaspoon almond extract omit if using maple syrup

Instructions

To make the crust:

• In a medium bowl, whisk together the flour, sugar, and salt.
  1 1/4 cups (150 grams) flour, 1/4 cup (50 grams) granulated sugar, 1/2 teaspoon salt
• Cut in the cold butter until the mixture resembles coarse breadcrumbs.
  1/2 cup (113 grams) unsalted butter
• In a separate small bowl, whisk the egg yolk, vanilla, and just 1 tablespoon of milk (ignore the amount below – it's a technical issue I can't fix). Stir this into the dry ingredients.
  1 large egg yolk, 1 teaspoon vanilla extract, 1-2 tablespoons milk
• Use your hands to work the dough a bit and to bring the dough together. The dough should be crumbly but cohesive when squeezed. It won’t form a ball or a loose ball like with pie dough.
• I placed a piece of plastic wrap in a mixing bowl and then dumped the dough into there and wrapped it up into a very loose, crumbly disc.
• Chill for 1 hour or up to 3 days.
• Grease 4 mini tart pans with removable bottoms.
• Take a fourth of the dough crumbles (I used 91 grams, but I used the extra tablespoon of milk – if you follow the recipe exactly, you can use 88 grams) and place in the pan.
• Press up the sides and evenly over the bottom of the pan. Do the same with the other 3 tart pans.
• Place in the fridge for at least 30 minutes or cover and refrigerate for up to 3 days.
• Towards the end of the chill time, preheat the oven to 375 °F (190 °C) and place a baking sheet large enough to fit all 4 tartlets in the lower third of your oven.
• After 30 minutes of chilling, place the tartlets directly onto the hot baking sheet and bake for 18-22 minutes, rotating halfway through if you notice them browning too quickly in certain areas, until the sides are nicely browned and the bottom has browned a bit.
• Remove the baking sheet and tartlets from the oven and place them on a wire rack to cool completely, about 1 hour (get started on Step 15 during this time). The crusts will crumble if you try to remove them from their pans while still warm. If making ahead of time, you can put the cooled crusts in an airtight container and store at room temp for up to 3 days or refrigerate for 5 days.
• Once cooled, unmold the crust – the removable bottom is going to stick to the bottom for now, and that’s okay.
• After about 40 minutes of cooling (or sooner if they cool more quickly in your kitchen), start the filling.

To make the blueberry filling:

• In a 1-quart (1-liter) saucepan, add 1 1/2 cups (225 grams) of blueberries, 1/3 cup (80 ml) water if using granulated sugar or 1/4 cup (120 ml) water if using maple syrup, granulated sugar and salt.
  1 1/2 cups (225 grams) fresh or frozen blueberries, 1/4 to 1/3 cup (60-80 ml) water, 2/3 cup (133 grams) granulated sugar, pinch salt
• Bring to a simmer over medium-high heat while stirring occasionally. When it’s almost simmering, mix together the cornstarch and water in a small bowl.
  1 1/2 tablespoons cornstarch
• Once the blueberries start simmering, stir in the cornstarch slurry.
• Turn the heat down to low and let it cook until it’s thickened – anywhere from 20-60 seconds. You don’t want it gloopy or too runny.
• Remove from the heat and stir in the almond and vanilla extracts.
  1/2 teaspoon vanilla extract, 1 teaspoon almond extract
• Carefully stir in 2 cups (300 grams) of fresh blueberries.
  2 cups (300 grams) fresh blueberries
• Let the sauce cool for about 10 minutes. It can be warm, but not steaming hot.
• Divide the filling between each cooled crust. Use 5 tablespoons (82 grams) per tart, and if there’s any left, add it. The exact amount the filling yields depends on your blueberries and exactly how thick the sauce is – I got different amounts every time, but always had at least 5 tbsp worth per tart.
• If you chill the filled tarts for 4+ hours and let the filling soak in a bit, then you’ll be able to easily remove the tart pan’s removable bottom from the tartlet. I think they’re most delicious after they’ve chilled for 4+ hours or the next day.

How to store:

• Once you’ve filled the tarts, they can be refrigerated for up to 3 days. You can freeze the unbaked or baked tart shells, but not the filling.

Notes

• For the flour, you can use all-purpose, whole wheat, or for gluten-free, use King Arthur Flour Gluten-free Measure for Measure Flour.
• You might need up to another tablespoon of milk to get the dough together. If it’s too dry with 1 tablespoon of milk, add a teaspoon at a time rather than dumping in another full tablespoon.
• The nutrition information provided is calculated as a courtesy and is only an estimate. I am not a licensed nutritionist or dietitian. For the most accurate nutritional data, consult a professional or use your preferred calculator.
• Crust very lightly adapted from King Arthur Flour.
