1. In a food processor, combine flour, cocoa powder, and salt. Add the cold butter cubes and powdered sugar, then pulse about 10 times until it looks like coarse crumbs (not smooth).
2. Add the egg and vanilla extract, then pulse just until the dough starts to come together in clumps. Don’t overdo it or your crust will be tough—I learned this the hard way.
3. Turn the dough out onto a clean surface, shape it into a disk, wrap it tightly in plastic wrap, and refrigerate for 30 minutes. This step is non-negotiable if you want hearts that actually look like hearts.
4. Preheat your oven to 350°F (180°C) and line a baking sheet with parchment paper.
5. Roll out the chilled dough on a floured surface to about 1/4 inch thickness. If it’s cracking, let it warm up for about 2 minutes. Cut out heart shapes using a cookie cutter (about 3-4 inches works best).
6. Place the heart-shaped tart shells on your prepared baking sheet and slide them into the oven. Bake for 12-15 minutes until they’re set but not rock hard—they’ll firm up as they cool.
7. Let the tart shells cool completely on the baking sheet before touching them. Moving them while hot = broken hearts, trust me.
8. For the ganache, combine chopped chocolate and heavy cream in a heatproof bowl. Microwave in 30-second intervals, stirring thoroughly between each burst, until it’s smooth and glossy (about 2-3 times total).
9. Spoon the warm ganache onto each cooled tart shell, filling them generously. Top immediately with fresh berries while the ganache is still soft.
10. Refrigerate the filled tarts for at least 30 minutes to let the ganache set properly. They should be firm but still creamy when you bite in.

Notes:

• Seriously, use cold butter for the crust. Room temperature butter makes greasy, tough pastry.
• Every oven runs differently, so start checking at 10 minutes. These can go from perfect to overbaked fast.
• If your ganache looks weird, you might have overheated it. Low and slow wins the race here.
• Heart-shaped cutters come in different sizes—adjust your dough thickness if using tiny ones.

Storage Tips:

• Store filled tarts in the refrigerator in a covered container for up to 3 days.
• Don’t freeze these—the texture gets weird when thawed.
• The shells alone can be stored at room temperature in an airtight container for 2 days before filling.
• Microwaving to reheat will turn them into rubber—just let them come to room temperature naturally if you want softer ganache.

Serving Suggestions:

• Dust with powdered sugar just before serving for an elegant touch
• Serve with whipped cream and fresh raspberries on the side
• Pair with champagne or sparkling cider for a romantic dessert
• Add a scoop of vanilla ice cream for an over-the-top treat

Mix It Up (Recipe Variations):

• White Chocolate Heart Tarts: Use white chocolate instead of semisweet for the ganache and add lemon zest
• Salted Caramel Heart Tarts: Drizzle salted caramel sauce over the ganache before adding berries
• Nutella Heart Tarts: Mix 2 tablespoons of Nutella into the ganache for hazelnut chocolate goodness
• Vegan Heart Tarts: Substitute coconut oil for butter in crust, use coconut cream for ganache, and top with dairy-free chocolate shavings
