Triple Chocolate Salted Caramel Brownie Bars with Caramel Swirls Tips, FAQ & printable recipe

Tips for success

Chop the chocolate by hand into small, irregular pieces rather than using chips, because chunks melt into pockets that give the brownie its triple chocolate character.

Chilling the bar of grating chocolate briefly before you shred it helps the curls stay intact and prevents the chocolate from smearing under the grater. Set the chopped caramel on a plate in the refrigerator for a few minutes so the pieces are easier to handle and do not stick to the board.

When you drizzle the caramel sauce and white chocolate, work quickly so both toppings stay fluid enough to swirl. A skewer gives finer lines than a fork, and short, light strokes keep the ribbons distinct.

Do not overswirl, or the colors blend into a uniform brown and the web pattern disappears. Save a small amount of the grated dark chocolate and a pinch of flaky sea salt for the final garnish, and add them only after slicing so they stay bright on each bar.

Variations

• Extra Dark Version: Replace the milk chocolate with an additional ounce of dark chocolate for a deeper, less sweet bar. The bitter edge balances the caramel and makes the chocolate flavor more pronounced in every slice.
• Walnut Variation: Use chopped walnuts or pecans in place of the hazelnuts. Toast them lightly before chopping to bring out a warm, nutty flavor that pairs well with the caramel and dark chocolate.
• Dulce de Leche Swirl: Swap the caramel sauce for thick dulce de leche, warmed slightly so it drizzles smoothly. The swirl becomes richer and more toffee-like, with a deeper caramel flavor throughout the brownie.
• Bar Pan Style: Bake the batter in an 8-inch square metal pan for thicker bars with a fudgier center. Add a few minutes to the bake and check the toothpick near the middle before removing the pan.

Storage and make-ahead

Fridge

Refrigerate in an airtight container for up to one week.

Freezer

Wrap each bar tightly in plastic wrap and freeze in an airtight container for up to three months.

Reheat

Warm a single bar in the microwave for about 10 seconds to soften the chocolate and caramel.

Store the cooled brownie bars in an airtight container at room temperature for up to three days. Layer parchment paper between the bars so the caramel and topping do not stick together.

Keep the container away from direct sunlight and heat sources so the chocolate stays firm and the caramel does not soften. If the kitchen is warm, move the container to a cool shelf. Cut the bars only as you need them, since the cut edges of an uncovered brownie dry out faster than the whole slab.

You can bake the brownie a day ahead. Cool it completely in the pan, cover the pan tightly with plastic wrap, and keep it at room temperature overnight. The next day, lift the slab from the pan, cut it into bars, and add the grated chocolate and flaky sea salt just before serving.

Making it ahead also gives the caramel and chocolate time to settle, which makes the bars easier to slice cleanly. Avoid refrigerating the baked brownie for long, because the chilled texture becomes firm and less fudgy.

Serving ideas

Serve the bars at room temperature so the fudgy center feels soft and the chocolate tastes rich. Set them on a platter with the caramel ribbons facing up, and sprinkle a little flaky sea salt over each bar just before guests arrive so the salt stays crisp. Pair them with a cup of strong coffee, cold milk or a simple scoop of vanilla ice cream, which balances the intensity of the dark chocolate and the sweetness of the caramel.

These bars suit a dessert table, a casual gathering or a gift box, since their thick, dense shape holds up well when stacked between sheets of parchment. For a more formal presentation, cut the bars into smaller squares and arrange them on a board with the grated chocolate and extra hazelnuts in small bowls. Let the bars come to room temperature before serving so the caramel softens slightly and the cut surface looks glossy.

Triple Chocolate Salted Caramel Brownie Bars with Caramel Swirls

Prep 30 minCook 30 minRest 2 hTotal 3 hServes 16

Ingredients

• 4 oz dark chocolate, chopped
• 2 oz milk chocolate, chopped
• 1/2 cup unsalted butter, cut into pieces
• 1 cup granulated sugar
• 2 large eggs, at room temperature
• 1 tsp vanilla extract
• 1/2 cup all-purpose flour
• 1/4 cup unsweetened cocoa powder
• 1/4 tsp fine sea salt
• 1/2 cup hazelnuts, roughly chopped
• 1/2 cup soft caramel pieces, chopped
• 1/4 cup caramel sauce
• 2 oz white chocolate, melted
• 1 oz dark chocolate, grated into curls and shavings
• flaky sea salt for serving

Instructions

1. Chop the dark chocolate, milk chocolate and hazelnuts on a wooden cutting board with a sharp knife. Chop the soft caramel pieces and set them aside. Grate a small portion of dark chocolate with a box grater into curls and shavings for the top.
2. Heat the oven to 350°F (175°C). Line a 9 by 13-inch metal baking pan with parchment paper, letting it overhang the sides. Melt the butter with the chopped dark and milk chocolate in a heatproof bowl set over simmering water, stirring until smooth. Whisk in the sugar, then the eggs one at a time and the vanilla.
3. Whisk the flour, cocoa powder and fine sea salt together, then fold them into the chocolate batter until just combined. Fold in the chopped hazelnuts and caramel pieces. Spread the batter evenly into the parchment-lined pan.
4. Melt the white chocolate until smooth. Drizzle the melted white chocolate and the caramel sauce over the batter in lines. Drag a skewer or toothpick through the drizzles in loose, crisscrossing strokes to form a web-like pattern.
5. Bake on the center rack for about 30 minutes, until the surface looks set and fudgy and a toothpick inserted near the center comes out with moist crumbs. Cool the brownie completely in the pan on a wire rack, about 2 hours.
6. Lift the cooled brownie from the pan using the parchment overhang. Cut into 16 bars with a sharp knife. Sprinkle each bar with the grated dark chocolate curls and a pinch of flaky sea salt before serving.
