Hazelnut Espresso Crunch Caramel Dark Chocolate Bars Tips, FAQ & printable recipe

Tips for success

For the cleanest slices, use a long, sharp chef's knife and wipe it clean between cuts. If the chocolate cracks while slicing, let the slab sit at room temperature for 10 minutes to soften slightly.

You can also score the top of the slab before it fully sets, then break along the lines once firm. This creates a rustic, artisanal look. When grating the chocolate, use a coarse grater and work quickly to avoid melting it with your hands. If the chocolate becomes too soft, chill it briefly.

To make the espresso toffee shards at home, crush store-bought toffee bits and toss them with a teaspoon of instant espresso powder. For the espresso salted caramel, warm your favorite caramel sauce and stir in a teaspoon of instant espresso powder and a pinch of sea salt.

This mimics the video's flavor profile without extra steps. The bars can be customized with different nuts or spices, but the combination of hazelnut, espresso, and dark chocolate is classic and hard to beat.

Variations

• Milk Chocolate Version: Swap the 70% dark chocolate for a high-quality milk chocolate (around 40% cacao) for a sweeter, creamier bar. Reduce the sugar in the caramel slightly to balance the sweetness. The result is a more indulgent treat that still has a satisfying snap.
• Nut-Free Alternative: Omit the hazelnuts and increase the toffee shards and cocoa nibs to 3/4 cup each. You can also add crushed pretzels for a salty crunch, but be mindful of gluten. This version is perfect for those with tree nut allergies.
• Sea Salt Sprinkle: Just before the chocolate sets, sprinkle the top with a pinch of flaky sea salt. The salt enhances the caramel and espresso flavors, adding a savory contrast that makes the bar even more addictive. Use a high-quality sea salt like Maldon.
• Orange Essence: Add 1 teaspoon of orange zest to the caramel before swirling, and mix 1 teaspoon of orange zest into the crunchy topping. The citrus brightens the dark chocolate and complements the espresso beautifully. This variation is especially festive.

Storage and make-ahead

Fridge

Store in an airtight container in the refrigerator for up to 2 weeks. Let stand at room temperature for 10 minutes before serving for best texture.

Freezer

Wrap bars tightly in plastic wrap and then foil; freeze for up to 3 months. Thaw in the refrigerator overnight before serving.

Reheat

No reheating needed; serve at room temperature or slightly chilled. If frozen, thaw in the refrigerator and bring to room temperature before serving.

Store the bars in an airtight container at room temperature for up to 1 week, or in the refrigerator for up to 2 weeks. If refrigerated, let them come to room temperature for 10 minutes before serving to restore the best texture. Keep them away from strong odors, as chocolate absorbs flavors. For longer storage, see the freezer note below. The bars maintain their snap and flavor best when kept in a cool, dry place.

These bars can be made up to 2 weeks ahead and stored in the refrigerator. They actually improve after a day as the flavors meld. To make ahead, prepare the bars completely, then wrap tightly in plastic wrap and store in an airtight container.

For longer storage, freeze for up to 3 months. When ready to serve, let the bars sit at room temperature for 15 minutes before breaking or slicing. This makes them perfect for holiday gifting or special occasions.

Serving ideas

Serve the bars at room temperature for the best flavor and texture. Arrange them on a platter or in a gift box lined with parchment paper. They pair beautifully with espresso or a glass of red wine.

The contrast of bitter chocolate, sweet caramel, and nutty crunch makes them a satisfying after-dinner treat. For a more elegant presentation, dust the bars with a little cocoa powder or flaky sea salt just before serving.

These bars are also wonderful broken into shards and used as a topping for ice cream, yogurt, or baked desserts. The pieces add a luxurious crunch and a hint of coffee. If you're serving a crowd, cut the bars into smaller squares or triangles. They are rich, so a little goes a long way. Store any leftovers in an airtight container to keep them fresh.

Hazelnut Espresso Crunch Caramel Dark Chocolate Bars

Prep 25 minCook 15 minRest 1 hTotal 1 h 40 minServes 12

Ingredients

• 16 oz 70% dark Belgian chocolate, finely grated
• 1 cup roasted hazelnuts, chopped
• 1/2 cup golden espresso toffee shards
• 2 tbsp cocoa nibs
• 3/4 cup warm espresso salted caramel

Instructions

1. Place the roasted hazelnuts on a cutting board and chop them with a sharp chef's knife until you have a mix of coarse and fine pieces. Add the golden espresso toffee shards and cocoa nibs to the board and chop everything together briefly so the toffee breaks into smaller shards and the nibs are evenly distributed. Transfer the mixture to a bowl and set aside.
2. Using a box grater, grate the solid block of 70% dark Belgian chocolate into a large bowl. Grate in long strokes to create light, fluffy curls rather than fine dust. You should have a generous pile of chocolate curls that will melt easily and evenly.
3. Place the grated chocolate in a heatproof bowl set over a pan of barely simmering water. Stir gently with a rubber spatula until the chocolate is completely melted and glossy. Remove from the heat and let it cool slightly, just until it thickens a bit but still pours smoothly.
4. Line an 8x8-inch metal tray with parchment paper, leaving overhang on two sides. Pour the melted chocolate into the tray and spread it into an even layer with the spatula, smoothing the top. Tap the tray gently on the counter to release any air bubbles.
5. Warm the espresso salted caramel until it is pourable but not boiling. Drizzle the caramel over the chocolate in a zigzag pattern. Use a knife or skewer to gently swirl the caramel into the chocolate, creating marbled ribbons without fully mixing them.
6. Sprinkle the chopped hazelnut, toffee, and cocoa nib mixture evenly over the caramel-swirled chocolate. Gently press the topping into the surface with your fingertips or the back of a spoon so it adheres. Let the slab set at room temperature until firm, about 1 hour.
7. Once the chocolate is completely set, lift the slab out of the tray using the parchment overhang. Place on a cutting board. Using a sharp chef's knife, slice the slab into thick bars, about 2 inches wide. Wipe the knife between cuts for clean edges.
8. Lift one bar and snap it cleanly in half to reveal the layered cross section. The layers should show the crunchy toffee, nutty texture, and smooth caramel against the dark chocolate. Serve the bars at room temperature or slightly chilled.
