Peanut Butter Caramel Crunch Dark Chocolate Fudge Slab

Glossy dark chocolate, ribbons of peanut butter caramel and a crunchy topping of roasted peanuts, banana chips and flaky sea salt make this fudge slab one of the most striking desserts you can set in a single pan. The result is dense, rich and firm enough to cut into clean, bold squares.

This dark chocolate fudge is built in layers. A simple chocolate base, poured into a parchment-lined metal pan, becomes the canvas for a swirl of thick peanut butter caramel.

A mix of roasted peanuts, banana chips and chopped caramel pieces goes over the top, finished with a pinch of flaky sea salt and a fine shower of grated dark chocolate.

Once set, the slab is cut in half and then into squares that reveal a dense chocolate interior edged with caramel and crunch.

The method asks for no candy thermometer and no complicated timing, only a little patience while the fudge firms up in the refrigerator. It suits a dessert table, a gift box or a weekend treat when you want something rich without a long baking session.

Ingredients

Why this recipe works

The fudge base works because condensed milk, butter and dark chocolate melt into a smooth, stable mixture that sets firm when chilled.

Melting everything over low heat keeps the chocolate glossy and prevents it from seizing, so the layer spreads evenly across the parchment and produces a clean, dense slice.

Layering the components instead of mixing them keeps each flavor distinct. The caramel swirl adds a salty-sweet contrast to the bitter dark chocolate, while the crunch mixture adds texture on the surface. Because the toppings are pressed into a set base, they stay in place when the slab is cut into pieces.

Notes and substitutions

Choose a dark chocolate with a clear cocoa percentage in the 60 to 70 percent range. It balances the sweetness of the condensed milk and the caramel. Roasted peanuts with their skins on are a good choice, since they add a deeper, toasted flavor to the crunch mix.

A 8-inch square metal pan is the right size for this slab, because it produces pieces of a practical thickness. Lining it with parchment paper lets you lift the whole slab out for cutting. A sharp long knife gives the cleanest edges, and a box grater makes the fine chocolate shavings that finish the top.

• dark chocolate: semisweet chocolate chips for a sweeter fudge
• banana chips: extra roasted peanuts for a plainer crunch
• unsalted butter: salted butter, with the added salt reduced
