Tips for success
Keep the fudge chilled while you cut it, and dip the knife in hot water between cuts. The warm blade glides through the caramel without dragging the toppings, which keeps each square looking neat and finished.
Use a light hand when scattering the crunch mixture. A single, even layer looks more striking than a heavy pile, and the toppings stay on each square instead of falling into the pan when you lift a piece.
Variations
- Extra Crunch: Add a second handful of roasted peanuts and banana chips to the top of the slab. The extra layer adds a thicker crunch and a more dramatic look for a dessert table or gift box.
- Milk Chocolate Version: Use milk chocolate for the base and grate a milk chocolate bar for the top. The fudge becomes sweeter and creamier, with the caramel and salt balancing the milder cocoa flavor.
- Thicker Slab: Pour the base into a smaller 6-inch pan for a taller slab. Extend the chilling time to about 3 hours, then cut thin, tall squares that show every layer of chocolate, caramel and crunch.
- Half Batch: Halve every quantity and bake the fudge in an 6-inch pan. The method stays the same, and the smaller slab sets in about 90 minutes, which suits a quick treat for two.
Storage and make-ahead
- Fridge
- Keep the cut fudge in an airtight container in the refrigerator for up to one week, with parchment between layers to keep the squares separate and neat.
- Freezer
- Wrap the uncut slab tightly in parchment and foil, then freeze it for up to 2 months. Thaw it overnight in the refrigerator before cutting.
Store the cut fudge in an airtight container in the refrigerator, with a sheet of parchment between layers so the squares do not stick together. Keep the container away from strong-smelling foods, since chocolate and butter absorb odors easily.
Let the squares sit at cool room temperature for about 10 minutes before serving so the chocolate softens slightly and the flavor opens up.
Do not leave the fudge out for long periods, because the butter and caramel can soften and the toppings can lose their crunch. Keep the fudge in the refrigerator for the best texture and clean slices.
This fudge is well suited to making a day ahead. Prepare the slab, top it and let it set in the refrigerator overnight, then cut it when ready to serve. The toppings stay crisp, the caramel keeps its ribbon pattern, and the chocolate base sets firm and glossy.
Making it ahead also gives the slab time to set fully, which produces neater squares. Store the uncut slab tightly wrapped in the refrigerator until you are ready to slice it, and cut only what you plan to serve.
Serving ideas
Serve the squares chilled or at cool room temperature, arranged on a small plate with a pinch of flaky sea salt on top for contrast.
Pair them with coffee, black tea or a cold glass of milk, which balance the bitterness of the dark chocolate and the richness of the caramel.
For a gift box or dessert table, wrap each square in parchment paper and stack them in a shallow container. The visible caramel swirl and crunchy topping make the pieces look appealing, and the dense chocolate interior holds up well when handled carefully.

Peanut Butter Caramel Crunch Dark Chocolate Fudge Slab

Ingredients
- 8 oz dark chocolate, plus extra bar for grating
- 1/2 cup unsalted butter
- 14 oz sweetened condensed milk
- 1 tsp vanilla extract
- 1/2 cup thick peanut butter caramel sauce
- 1/2 cup roasted peanuts, chopped
- 1/2 cup banana chips, broken into pieces
- 1/3 cup chopped caramel pieces
- flaky sea salt, to taste, plus a pinch for finishing
Instructions
- Line the metal pan with parchment paper, letting it overhang the sides. Melt the dark chocolate, butter and sweetened condensed milk together over low heat, stirring until smooth and glossy. Stir in the vanilla extract and remove from the heat.
- On a cutting board, combine the roasted peanuts, banana chips, chopped caramel pieces and a pinch of flaky sea salt. Chop with a knife, gathering the pile back together several times, until the crunchy toppings are evenly mixed.
- Hold an extra dark chocolate bar against a box grater and grate it over the cutting board. The fine, curled shavings will fall onto the board. Set them aside for the topping.
- Pour the chocolate base into the parchment-lined pan and spread it until it covers the bottom in a smooth, even layer. Warm the peanut butter caramel slightly if needed, then drizzle it across the chocolate and swirl it into ribbon-like streaks with a spoon.
- Scatter the peanut and caramel crunch mixture over the top, pressing it lightly so it adheres. Add the grated chocolate shavings and finish with a pinch of flaky sea salt. Refrigerate until firm, about 2 hours.
- Lift the set fudge out of the pan using the parchment overhang. Cut the slab in half with a long, sharp knife, then cut each half into even pieces. Wipe the knife between cuts for clean edges.
