Grated dark chocolate fudge becomes the base of a glossy bar, with peanut butter caramel ribbons, salted peanuts and toffee crunch running through every layer. It needs no oven and only a few tools, and it is ready to slice once it has set.
This bar starts with a block of dark chocolate fudge, which you cut, scatter with peanuts and toffee, and then grate over a board into fine shavings. Those shavings become the foundation of the pan, so the bar has a rich, dark chocolate base before anything else goes on.
Melted dark chocolate is poured over the base and swirled with ribbons of peanut butter caramel, then the top is finished with handfuls of whole salted peanuts, a light pinch of flaky salt and a pattern of caramel swirls.
After the slab sets, you dust it with cocoa and slice it down the center to reveal the layers inside. The result is a firm, clean-cut dessert that tastes of dark chocolate, roasted peanut and buttery toffee in every bite.
Ingredients
- 1 block dark chocolate fudge, store-bought or made ahead
Crunch
- 1/2 cup salted peanuts, chopped
- 1/2 cup crunchy toffee pieces
Chocolate layer
- 8 oz dark chocolate, chopped
Caramel
- 1/2 cup smooth peanut butter
- 1/2 cup caramel sauce, store-bought or made ahead
Topping
- 1/2 cup whole salted peanuts
- flaky salt, to taste
Finish
- unsweetened cocoa powder, for dusting, to taste
Why this recipe works
The grated fudge works as a base because its fine shavings pack together and hold their shape under the melted chocolate. Because the base is already sweet and rich, the poured chocolate on top can stay simple and glossy, and the bar keeps its structure when sliced.
Swirling the caramel and peanut butter into the melted chocolate rather than fully blending them creates the ribbons that show in the finished cut face. Only a few passes with a spatula keep the colours separate, and the salted peanuts and toffee add a crunch that contrasts with the smooth fudge.
Notes and substitutions
Choose a firm dark chocolate fudge block for the grated base, since a soft block will smear instead of forming shavings. Use smooth peanut butter so it swirls easily, and a thick caramel sauce so the ribbons hold their shape rather than sinking into the chocolate.
Salted peanuts and toffee pieces should be crunchy, because soft toffee loses its texture once it touches the melted chocolate.
You need a wooden cutting board, a long knife for cutting the fudge, and a box grater for the shavings. A metal baking pan of about 8 by 8 inches gives a bar of the right thickness, and lining it with parchment paper makes the slab easy to lift out.
A microwave-safe bowl and a spatula handle the melting and swirling. If you lack a specific ingredient, dulce de leche can stand in for the caramel, and chopped English toffee can replace the toffee pieces.
