If you love the contrast of bitter dark chocolate and sweet, salty caramel, these bars are for you. The base is a rich, glossy layer of 70% dark Belgian chocolate, which is then swirled with warm espresso salted caramel and topped with a crunchy mix of roasted hazelnuts, espresso toffee shards, and cocoa nibs.

Once set, the slab is sliced into thick bars that snap cleanly, revealing a beautiful layered interior. They are simple to make, require no oven, and are perfect for gifting or keeping on hand for a sophisticated sweet treat.

Ingredients

Why this recipe works

The method relies on a few key techniques to achieve the perfect texture. First, grating a block of dark chocolate creates delicate curls that add a light, airy texture and a beautiful visual contrast when scattered on top.

Second, swirling warm caramel into the melted chocolate creates ribbons of gooey, salty-sweet goodness that contrast with the firm chocolate base. Finally, chilling the slab thoroughly ensures a clean, crisp snap when you slice and break the bars.

The combination of ingredients is carefully balanced: the bitterness of the 70% dark chocolate is offset by the sweetness of the caramel and toffee, while the roasted hazelnuts and cocoa nibs add a deep nutty and slightly earthy crunch. The espresso in the caramel and toffee enhances the chocolate's flavor without overwhelming it, creating a sophisticated treat that appeals to both chocolate lovers and coffee enthusiasts.

Notes and substitutions

The quality of the chocolate matters here. Use a good 70% dark Belgian chocolate, either in bar form or as callets. If you cannot find Belgian, any high-quality dark chocolate with at least 60% cacao will work. The chocolate is used in two ways: melted for the base and grated for the topping, so buy a block that is easy to grate.

The espresso salted caramel can be homemade or store-bought. If making your own, ensure it is warm and pourable when you swirl it into the chocolate.

The espresso toffee shards are also available at specialty stores, but you can substitute with crushed espresso beans or a mix of toffee bits and instant espresso powder. Roasted hazelnuts are essential for the best flavor; if you only have raw ones, toast them in a dry skillet until fragrant.

• 70% dark Belgian chocolate: Any good-quality dark chocolate (60-70% cacao) can be used; avoid chocolate with added milk for a more intense flavor.
• roasted hazelnuts: Use almonds or pecans if hazelnuts are not available; toast them lightly to enhance their flavor.
• espresso toffee shards: Crushed espresso beans or a mix of toffee bits and instant espresso powder can substitute for the toffee shards.
• espresso salted caramel: Regular salted caramel with a shot of espresso or strong coffee works well.
