Ingredients You’ll Need

This recipe calls for straightforward yet essential ingredients that each play a crucial role in delivering the perfect taste, texture, and stunning appearance of the Blackberry Lavender Custard Tart. From the flaky crust to the luscious filling, you’ll see how these pantry staples combine beautifully.

Flour (1 ¾ cups): The foundation for the tart crust, providing structure and that sought-after crumbly texture.
Sea salt (¾ teaspoons): Enhances the flavors and balances the sweetness for a more layered taste.
Sugar (1 ½ teaspoons for crust, plus 3 tablespoons for filling): Adds just enough sweetness to the crust and filling without overpowering.
Butter, chilled and cubed (½ cup): Creates a tender, flaky crust thanks to its cold temperature and fats.
Vanilla extract (1 teaspoon for crust, plus ½ teaspoon vanilla paste for filling): Infuses warm, comforting notes that pair beautifully with blackberries and lavender.
Cold water (¼ cup + 2 tablespoons): Brings the dough together gently without making it tough.
Blackberries (2 ½ cups, plus some extra): Fresh and vibrant, they burst with juicy sweetness and a bit of tartness that perfectly complements the creamy custard.
Whole milk honey yogurt (1 cup): Adds creaminess and a subtle tang to the custard filling, enhancing depth of flavor.
Eggs (2): Essential for binding and giving the custard its rich, silky texture.
Lavender extract (½ teaspoon): Delivers delicate floral notes that elevate this tart beyond ordinary desserts.
Honey: For drizzling on top, adding a natural sweetness and a glossy finish to your tart.

How to Make Blackberry Lavender Custard Tart

Step 1: Make the Crust

Start off by preheating your oven to 375˚F to create the perfect baking environment. Mix the flour, sugar, and sea salt together in a large bowl so the dry ingredients are evenly combined. Cut in the chilled, cubed butter using a pastry blender or two forks until the mixture looks like pea-sized crumbs—this is key to your flaky crust. Then stir in the vanilla extract and cold water just enough for the dough to clump together. Turn the dough onto a floured surface and fold it gently until it forms a smooth ball. Remember, if it feels sticky, add more flour bit by bit. Then pat the dough into a disc, wrap it in plastic, and chill it for 15 minutes to one hour to let it rest and firm up.

Step 2: Prepare the Tart Shell

Once chilled, roll the dough out to a 12-inch circle on a lightly floured surface. Line an 11-inch removable-bottom tart pan with the crust and prick the bottom with a fork to avoid air bubbles during baking. Layer parchment paper inside the crust and fill it with pie weights or dried beans. Bake for 10 minutes, then carefully remove the weights and parchment paper and bake a little longer until the crust has a faint golden hue. Let it cool completely before adding your filling.

Step 3: Make the Custard Filling

Whisk together eggs, sugar, vanilla paste, and the beautifully fragrant lavender extract until smooth and well blended. Stir in the whole milk honey yogurt gently to maintain a velvety texture. This mixture is where the magic happens: the floral notes, the creamy tang, and the sweetness combine to make a custard that’s out of this world.

Step 4: Assemble and Bake

Spread your fresh blackberries evenly over the cooled tart shell, layering flavor and texture. Pour the custard mixture carefully over the berries, filling the tart pan, then dot the top with a few extra blackberries for a charming visual and fruity pop. Bake everything for 40 to 45 minutes, until the crust shines golden and the custard is set but still has a slight wobble in the center, signaling creamy perfection.

Step 5: Cool and Finish

Let your Blackberry Lavender Custard Tart cool for about 5 minutes after baking to allow the filling to firm just a touch more. Finish by drizzling a little honey on top to add that gorgeous, glossy sheen and an extra layer of sweet floral flavor. Then slice and enjoy the fruits of your labor!

How to Serve Blackberry Lavender Custard Tart

Garnishes

This tart looks and tastes incredible with a few simple garnishes. Fresh blackberries on top enhance the natural berry flavor and add a lovely burst of color. A sprig of fresh lavender or edible flowers not only ties in the floral notes but makes your dessert irresistible to the eyes. A light dusting of powdered sugar can add a delicate touch of sweetness and charm.

Side Dishes

The Blackberry Lavender Custard Tart pairs beautifully with a dollop of whipped cream or a scoop of vanilla bean ice cream, which adds creamy richness and contrasts the tart’s smooth custard and flaky crust. For a refreshing twist, serve alongside a citrusy fruit salad or a simple green herbal tea that complements the lavender’s subtle floral aroma.

Creative Ways to Present

To truly make your tart the star of the table, serve it on a rustic wooden board or a vintage cake stand that adds a homey, elegant vibe. Slice it into wedges and drizzle additional honey or a berry coulis on each plate for an artistic flair. For gatherings, mini versions of this Blackberry Lavender Custard Tart can be baked in tartlet pans making for perfect, giftable treats.

Make Ahead and Storage

Storing Leftovers

You can store leftover Blackberry Lavender Custard Tart in the fridge, covered tightly with plastic wrap or an airtight container. It will keep wonderfully for 3 to 4 days, maintaining that lovely custard creaminess and crust crispness when properly stored.

Freezing

Freezing this tart is possible but we recommend doing so only with the crust beforehand and assembling fresh when ready to bake for best texture. If freezing the whole tart, wrap it well in plastic wrap and then foil to avoid freezer burn. Thaw in the refrigerator overnight before serving.

Reheating

To enjoy the tart warm, reheat it gently in an oven preheated to 325˚F for about 10 minutes. This softens the custard slightly and refreshes the crust’s crispness without compromising texture or flavor.

FAQs

Can I substitute fresh blackberries with frozen ones?

Absolutely! Just make sure to thaw and gently drain the frozen blackberries to prevent excess moisture from making the tart soggy. Frozen berries can be a convenient alternative and still deliver great flavor.

Is lavender extract strong? How much should I use?

Lavender extract can be potent, so stick to the recommended ½ teaspoon for this recipe for a subtle floral hint that complements without overpowering. You can adjust slightly to taste if you prefer a milder or bolder lavender aroma.

Can I make this tart vegan or dairy-free?

While this recipe relies on dairy and eggs for its signature custard texture, you can experiment using plant-based yogurt, a flax or chia egg substitute, and vegan butter for the crust. The flavors will still be delightful but the texture may vary.

What kind of tart pan works best?

A removable-bottom tart pan is ideal, making it easier to release the Blackberry Lavender Custard Tart without damaging the delicate crust. A size around 11 inches provides a beautiful balance between filling and crust.

How can I tell when the custard is perfectly baked?

The custard should be set around the edges but retain a slight wobble in the center when gently shaken. It will continue to set as it cools, giving you a creamy, smooth filling without being dry or overly firm.

Final Thoughts

Making this Blackberry Lavender Custard Tart is truly a joyful experience that rewards you with a dessert that looks as stunning as it tastes. It’s a perfect mix of floral, fruity, and creamy that can brighten any occasion or quiet moment at home. I encourage you to try this recipe and savor every bite of this warm, fragrant, and elegant tart that’s sure to become a treasured favorite in your recipe collection.

Description

This Blackberry Lavender Custard Tart combines a buttery, flaky crust with a fragrant, creamy lavender-infused custard filling and juicy blackberries. Perfect for a sophisticated dessert or a special occasion treat, it offers a delicate floral aroma balanced by the sweetness of honey yogurt and fresh blackberries.

Instructions

Preheat the oven: Set your oven to 375˚F (190˚C) to prepare for baking the tart shell.
Make the crust mixture: In a large bowl, combine the flour, sugar, and sea salt. Add the chilled, cubed butter and cut it into the flour mixture using a pastry blender or two forks until the pieces resemble peas.
Add liquids and form dough: Stir in the vanilla extract and cold water until the dough begins to clump together. Transfer to a floured surface and knead gently, adding more flour if sticky, until it forms a smooth ball.
Chill the dough: Flatten the dough into a ½ inch thick disc, wrap in plastic wrap, and refrigerate for 15 minutes to 1 hour to firm up.
Roll and prepare crust: Roll the chilled dough to a 12-inch circle on a lightly floured surface. Line an 11-inch removable-bottom tart pan with the dough, trimming edges if needed.
Blind bake the crust: Prick the bottom with a fork, line with parchment paper, fill with pie weights, and bake for 10 minutes. Remove parchment and weights, then cool completely.
Prepare the filling: In a bowl, whisk eggs, sugar, vanilla paste, and lavender extract together. Stir in the honey yogurt until well combined.
Assemble the tart: Spread blackberries evenly over the cooled crust. Pour the custard filling over the berries and dot the top with a few extra blackberries for garnish.
Bake the tart: Bake in the oven for 40 to 45 minutes, until the crust is golden and the custard is set but still slightly jiggly in the center.
Cool and serve: Let the tart cool for 5 minutes, then drizzle honey over the top before slicing and serving.

Notes

Use fresh blackberries for best flavor and texture.
Lavender extract is potent, so measure carefully to avoid an overpowering floral taste.
Honey yogurt adds sweetness and creaminess; plain yogurt with honey can substitute if unavailable.
Blind baking the crust prevents sogginess by setting it before adding the custard filling.
Allow the tart to cool slightly before serving to let the custard set fully.
Store leftovers covered in the refrigerator and consume within 2-3 days.
