If you love playing with chocolate finishes, you might also enjoy my take on a dark chocolate mirror glaze for a show-stopping finish (warning: mirror glaze looks glamorous but can be forgiving if you don’t have a pastry degree). Now, let’s get into why these bars should be on your dessert roster.

Ingredients

Makes one 9×13-inch pan (about 12–16 bars)

Crust and base:

2 cups (240g) all-purpose flour
1/2 cup (60g) powdered sugar
3/4 teaspoon salt
1 cup (226g) unsalted butter, cold and cubed
1 teaspoon vanilla extract

Chocolate filling:

10 oz (280g) dark chocolate (60–72% cocoa), chopped
1 cup (240ml) heavy cream
2 tablespoons unsalted butter
1/4 cup (50g) granulated sugar (optional—depending on chocolate bitterness)
1 teaspoon vanilla extract

Raspberry swirl:

2 cups (about 250g) fresh or frozen raspberries
2–3 tablespoons granulated sugar (adjust to taste)
1 tablespoon lemon juice
1 teaspoon cornstarch (optional, for thickening)

Optional topping:

Flaky sea salt, for sprinkling
Fresh raspberries or powdered sugar for garnish

Notes:

If you want a quicker shortcut, a pressed cookie crumb crust can work; but the shortbread-style base here gives a lovely sturdy bite.
Using high-quality dark chocolate will make a big difference in flavor.

Step-by-step: How to make Dark Chocolate Raspberry Pie Bars

Preheat and prep: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang for easy lifting. Lightly grease the pan if your parchment won’t fully cover the sides.
Make the crust: In a large bowl, whisk together the flour, powdered sugar, and salt. Add cold cubed butter and, using a pastry cutter, two forks, or your clean fingertips, cut the butter into the dry ingredients until the mixture resembles coarse crumbs with some pea-sized pieces. Stir in the vanilla.
Press and bake the base: Press about two-thirds of the crust mixture firmly and evenly into the bottom of the prepared pan to form a compact base. Reserve the remaining third for a crumble topping. Bake for 15–18 minutes, or until the edges are lightly golden. Remove from oven and set aside.
Make the raspberry swirl: While the crust bakes, place raspberries, sugar, and lemon juice into a small saucepan over medium heat. Cook, stirring, until raspberries break down and the mixture becomes saucy (5–8 minutes). If you want a thicker swirl that won’t bleed into the chocolate too much, dissolve 1 teaspoon cornstarch in a splash of water and stir in, cooking for another minute. Remove from heat and let cool slightly. For a seedless finish, press through a fine mesh sieve—this step is optional but lovely if kids or guests don’t love seeds.
Prepare the chocolate filling (ganache-style): In a heatproof bowl, combine chopped dark chocolate and butter. Heat the cream in a small saucepan until it just starts to simmer (do not let it boil). Pour the hot cream over the chocolate and let sit 30–60 seconds, then gently whisk until glossy and smooth. Add sugar only if you prefer a sweeter bar, then swirl in vanilla.
Assemble: Pour the chocolate filling over the baked crust and spread gently to an even layer. Dollop spoonfuls of the raspberry sauce across the chocolate, then use a knife or skewer to swirl the raspberry into the chocolate in a loose, pretty pattern—don’t overmix or the swirl will disappear.
Add the crumble: Sprinkle the reserved crust crumbs evenly over the top. The crumbs will bake into a slightly crunchy top during the finishing bake.
Bake and cool: Bake at 350°F (175°C) for another 12–15 minutes, until the crumb topping is lightly golden and the chocolate has set around the edges. Cool completely on a wire rack, then chill in the refrigerator for at least 2 hours to fully set the chocolate (overnight is even better).
Slice and serve: Lift the bars from the pan using the parchment overhang and slice into bars. Sprinkle with flaky sea salt or powdered sugar and garnish with fresh raspberries if desired.

Tip: Warm the knife under hot water and wipe between cuts for cleaner slices.

Cooking tips & tricks (from our busy kitchen)

Chill for clean cuts: These bars slice much more neatly after refrigeration. If you’re short on time, 30–45 minutes in the freezer can help, but don’t freeze solid unless you want to defrost before serving.
Seedless swirl: If texture matters (think picky kids or elegant guests), strain the raspberry sauce through a sieve to remove seeds—Patricia refuses to eat raspberries with seeds, so I learned the hard way.
Balance the sweetness: Dark chocolate can be bitter depending on cocoa percentage. Taste the ganache before pouring—if you want it sweeter, fold in a tablespoon or two of sugar or honey.
Swap options: Use mixed berries if raspberries aren’t available, or substitute a jarred seedless raspberry jam thinned with a few tablespoons of water for a quicker swirl.
Make ahead: These bars keep well in the refrigerator up to 5 days, making them a terrific make-ahead dessert.

A little kitchen story

When I first tested this recipe, I was juggling a toddler, a conference call, and a dinner party the same evening—classic multitasking chaos. I pulled these bars together between diaper changes and emails, popped them in the oven, and somehow they turned into the dessert everyone raved about. My sister Patricia declared them "dangerously good" and then proceeded to eat two before dinner. That’s when I knew this recipe was a keeper: easy, forgiving, and worthy of applause (or at least an extra slice).

Frequently asked questions

Q: Can I use frozen raspberries?
A: Yes. Use frozen raspberries directly; they’ll cook down into the sauce. Thawing first will speed things up, but it’s not necessary.

Q: Can I make these gluten-free?
A: Replace the all-purpose flour with a 1:1 gluten-free flour blend that contains xanthan gum. The texture will be slightly different but still delicious.

Q: How should I store leftovers?
A: Keep them covered in the fridge for up to 5 days. For longer storage, freeze individual bars in an airtight container for up to 3 months.

Q: Can I make mini versions or a 9-inch square instead?
A: Absolutely. For an 8×8 or 9-inch square, reduce bake time slightly and watch for the edges to set. The flavor is the same—just fewer bars.

Q: What chocolate should I use for the filling?
A: Aim for good-quality dark chocolate between 60–72% cocoa. If you prefer sweeter bars, use a sweetened dark or semisweet chocolate. Avoid chocolate chips labeled for baking only; chopped chocolate melts more evenly.

Serving ideas

Serve with whipped cream or a scoop of vanilla ice cream for an indulgent finish.
For a lighter touch, dust with powdered sugar and add a few fresh mint leaves.
These bars also pair well with a cup of strong coffee or a glass of dessert wine for a grown-up treat.
