Featured in: Baking Made Simple

This elegant tart brings together a crisp, buttery tart shell with a rich, fudgy dark chocolate brownie center. The 70% cocoa chocolate creates a sophisticated flavor profile that's deeply satisfying for serious chocolate enthusiasts. With just over an hour of total time, it's an achievable yet impressive dessert that looks as decadent as it tastes. The key is not overbaking the center—aim for slightly soft edges that will set as it cools, ensuring maximum fudginess.

The first time I made this chocolate brownie tart, my kitchen filled with that unmistakable aroma of dark chocolate melting slowly into butter. I had been experimenting with desserts that could impress at a dinner party without requiring pastry chef skills. My hands were dusty with flour as I pressed the dough into the tart pan, thinking this might just become my signature dessert.

Last winter, I brought this tart to my friends annual holiday gathering. The room fell quiet as everyone took their first bites, followed by sighs and requests for the recipe. Even Marcus, who always claims hes not a dessert person, asked for seconds. I watched the tart disappear slice by slice, faster than any other dessert on the table.

Ingredients

  • Dark Chocolate (70% cocoa): The soul of this recipe—I learned through trial and error that chocolate with at least 70% cocoa content gives the brownie filling that complex, not-too-sweet intensity that makes people close their eyes when they take a bite.
  • Cold Butter for Tart Shell: Keep it properly chilled until the last moment; those cold butter pieces create the flaky texture that makes the shell crack perfectly with each forkful.
  • Brown Sugar: After making this tart dozens of times, I discovered brown sugar adds a subtle caramel note that deepens the chocolate flavor in a way white sugar alone never could.
  • Vanilla Extract: Just a teaspoon creates an aromatic foundation that enhances the chocolate without announcing itself—pure extract makes a noticeable difference here.

Instructions

Prepare the foundation:
Preheat your oven to 350°F and grease that 9-inch tart pan, making sure to get into all the fluted edges. A removable bottom pan isnt just convenient, its essential for serving this beauty intact.
Create the buttery shell:
Work the cold butter into the flour mixture with your fingertips until you feel that perfect sandy texture. The dough should just barely come together when you add the egg yolk and water—youll know its right when it stops being crumbly but before it becomes sticky.
Pre-bake with patience:
After chilling, roll out the dough and gently press it into your pan, trimming any rebellious edges. Those little fork pricks in the base prevent bubbles from forming as it bakes into a golden canvas for our brownie filling.
Craft the velvet filling:
Melt the chocolate and butter together slowly, watching as they transform into a glossy pool. This is my favorite part—the moment the kitchen fills with that intoxicating chocolate aroma that draws everyone in.
Bring it all together:
Fold the flour into your chocolate mixture just until no dry streaks remain. Overmixing is the enemy here—you want that dense, fudgy texture that makes brownies irresistible.
Find the perfect bake:
The tart is done when the edges are set but the center still has a slight wobble. Trust me on this—it continues cooking after you remove it from the oven, and that slight underbake creates the decadent texture everyone will rave about.

One summer evening, I served this tart on my patio with tiny glasses of dessert wine and watched fireflies blink in the garden. My neighbor Elaine, whod been having a rough week, took a bite and her shoulders visibly relaxed. Sometimes the best thing you can offer someone is chocolate and a moment of pure pleasure, no words needed.

Serving Suggestions

Ive found this tart needs nothing more than a light dusting of cocoa powder for everyday occasions, but fresh berries add a welcome brightness that cuts through the richness. For dinner parties, I place a small dollop of barely sweetened whipped cream beside each slice and scatter a few raspberries across the plate—the ruby red against the dark chocolate creates a stunning presentation that takes mere seconds.

Storage Tips

After making this countless times, Ive learned it actually improves with a day of rest, as the flavors meld and deepen. Store it at room temperature under a cake dome for up to three days, though it rarely lasts that long in my house. If your kitchen runs warm, refrigerate it but always bring slices back to room temperature before serving to experience the full range of flavors and that perfect fudgy texture.

Variations to Try

The basic recipe has become my canvas for seasonal adaptations that keep it exciting no matter how often I make it. During winter holidays, I add a quarter teaspoon of orange zest to the brownie batter, while summer calls for a handful of fresh cherries pressed gently into the top before baking.

  • For an autumn version, fold in a half cup of chopped toasted hazelnuts and dust with cinnamon-spiked cocoa powder.
  • A spoonful of espresso powder mixed into the chocolate creates a mocha variation that disappears especially quickly at brunch gatherings.
  • For true chocolate aficionados, replace a quarter cup of the flour with unsweetened cocoa powder for an even more intense chocolate experience.

This tart has become more than just a recipe in my collection—its my go-to comfort, celebration, and everything-in-between dessert. The quiet satisfaction of watching someone take their first bite is perhaps the sweetest part of all.

Recipe FAQs

How do I prevent the tart shell from becoming soggy?

Blind bake the tart shell before adding the brownie filling. Line it with parchment paper and pie weights or dried beans, then bake for 15 minutes. This creates a barrier that keeps the pastry crisp while the filling bakes.

Can I make the tart shell ahead of time?

Yes, prepare the dough up to 3 days in advance and refrigerate it. You can also blind bake the shell 1-2 days ahead and store it in an airtight container. Fill it shortly before serving for best texture.

What does it mean when the center should be slightly soft?

The brownie should appear just set around the edges with a slight jiggle in the very center when you gently shake the pan. This indicates carryover cooking will finish it as it cools, resulting in that perfect fudgy texture rather than a cake-like crumb.

Can I substitute the dark chocolate for milk chocolate?

You can, but it will change the flavor profile significantly. Milk chocolate will be sweeter and less intense. Stick with 60-70% cocoa for the best balance of richness and sophistication that defines this dessert.

How should I store leftover tart?

Cover and refrigerate for up to 4 days. Serve at room temperature for the best flavor and texture, or gently warm slices for 10-15 seconds in the microwave if you prefer a warmer, more fudgy consistency.

What's the difference between using pie weights and dried beans?

Both work equally well for blind baking. Pie weights heat more evenly and are reusable indefinitely, making them slightly preferable. Dried beans are a budget-friendly alternative, though they may darken over time with repeated use.

04 1/2 cup cold unsalted butter, cubed
05 1 large egg yolk
06 1-2 tablespoons cold water

Brownie Filling

01 7 oz dark chocolate (70% cocoa), chopped
02 1/2 cup unsalted butter, cubed
03 3/4 cup granulated sugar
04 1/4 cup brown sugar
05 2 large eggs
06 1 teaspoon pure vanilla extract
07 1/4 teaspoon salt
08 1/2 cup all-purpose flour

Optional Garnish

01 Cocoa powder or powdered sugar for dusting
02 Fresh berries or whipped cream

How to Make It

Step 01

Prepare Oven and Pan: Preheat the oven to 350°F. Grease a 9-inch tart pan with a removable bottom.

Step 02

Make Tart Dough: In a bowl, whisk together flour, powdered sugar, and salt. Add cold butter and rub in with your fingertips or use a pastry cutter until the mixture resembles coarse crumbs. Add egg yolk and 1 tablespoon cold water; mix until the dough just comes together, adding an extra spoonful of water if needed. Form into a disk, wrap, and chill for 15 minutes.

Step 03

Prebake Tart Shell: Roll out the dough on a lightly floured surface and press into the prepared tart pan. Trim excess dough. Prick the base with a fork. Line with parchment and fill with pie weights or dried beans. Bake for 15 minutes, remove weights and paper, then bake for 5 more minutes until lightly golden. Let cool slightly.

Step 04

Prepare Brownie Filling: Melt chocolate and butter together in a heatproof bowl over a pan of gently simmering water (or microwave in 20-second bursts), stirring until smooth. Cool slightly.

Step 05

Complete Brownie Batter: Whisk in granulated sugar, brown sugar, eggs, vanilla, and salt until combined. Fold in flour until just incorporated. Do not overmix.

Step 06

Assemble Tart: Pour the brownie batter into the cooled tart shell. Smooth the top.

Step 07

Bake: Bake for 18-20 minutes, or until the edges are set but the center is still slightly soft. Do not overbake; the tart will set as it cools.

Step 08

Cool and Garnish: Cool completely on a wire rack. Dust with cocoa powder or powdered sugar and garnish as desired before serving.
