Tips for success
For the cleanest slices, use a large, sharp chef's knife and wipe it with a damp cloth between cuts.
If the chocolate starts to soften during slicing, return the slab to the fridge for a few minutes. You can also dip the knife in hot water and dry it before each cut to get smooth, even edges.
To make the chocolate curls, use a vegetable peeler on a thick block of blonde chocolate, or grate it on a box grater. For larger, more dramatic curls, warm the block slightly in your hands before shaving.
Store the curls in an airtight container in a cool place until ready to use, and handle them gently to avoid breaking.
Variations
- Salted Caramel Swirl: Swap the cookie butter for a thick salted caramel sauce. Swirl it in just before chilling, and sprinkle flaky sea salt over the top for a sweet-salty contrast.
- Nutty Crunch: Add a layer of toasted, chopped hazelnuts or pecans on top of the chocolate curls for extra crunch. The nuts complement the caramelized flavor of the blonde chocolate.
- Spiced Chocolate: Mix a pinch of cinnamon, ginger, and nutmeg into the melted blonde chocolate before pouring. This adds a warm, festive spice that pairs well with the cookie butter.
- White Chocolate Raspberry: Use white chocolate instead of blonde, and swirl in a few spoonfuls of raspberry jam along with the cookie butter. The tartness of the raspberries balances the sweetness.
Storage and make-ahead
- Fridge
- Store in an airtight container in the refrigerator for up to 2 weeks. Separate layers with parchment paper to prevent sticking.
- Freezer
- Wrap the slab or individual 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. Let bars sit at room temperature for 5-10 minutes before serving for the best texture.
Store the bars in an airtight container in the refrigerator for up to 2 weeks.

These bars are ideal for making ahead. Prepare the full recipe, chill, and slice. Store in the refrigerator for up to 2 weeks, or freeze for longer storage. They can be assembled up to 3 days before serving without losing quality.
Serving ideas
Serve the bars at cool room temperature for the best contrast between the fudgy base and the crunchy topping.
Arrange them on a platter for a party or wrap individually in parchment for a gift. They pair beautifully with coffee, espresso, or a glass of cold milk.
For a more elegant presentation, dust the tops with a little cocoa powder or flaky sea salt before serving, though the bars are delicious as is. The clean snap and visible layers make them a striking addition to any dessert table.

Biscoff Blonde Chocolate Crunch Bars

Ingredients
- 16 oz blonde chocolate (caramelized white chocolate), finely chopped
- 1/2 cup Speculoos cookie butter
- 1 cup blonde chocolate curls (from a solid block)
Instructions
- Line an 8x8-inch baking pan with parchment paper, leaving overhang on two sides for easy lifting. Grate a solid block of blonde chocolate on the large holes of a box grater to make about 1 cup of curls. Set the curls aside in a cool, dry place.
- Place the chopped blonde chocolate in a heatproof bowl. Set the bowl over a saucepan of barely simmering water, making sure the bottom does not touch the water. Stir frequently with a rubber spatula until the chocolate is completely melted and smooth. Remove from heat.
- Pour the melted blonde chocolate into the prepared pan. Tilt the pan gently to spread it into an even layer, smoothing the top with the spatula if needed.
- Warm the Speculoos cookie butter slightly in the microwave or in a small saucepan until it is pourable but not hot. Drop spoonfuls of cookie butter over the melted chocolate. Use a knife or skewer to swirl it through the chocolate in a ribbon pattern.
- Immediately sprinkle the reserved blonde chocolate curls evenly over the top of the swirled chocolate. Press them gently into the surface so they stick.
- Transfer the pan to the refrigerator and chill for at least 2 hours, or until the chocolate is completely firm and set.
- Lift the chilled slab out of the pan using the parchment overhang. Place on a cutting board. Using a sharp chef's knife, cut the slab into thick bars, about 2 inches wide and 3 inches long. Wipe the knife clean between cuts for neat edges.
- To serve, lift a bar and snap it cleanly in half to reveal the layered cross section. Arrange the bars on a serving plate or store in an airtight container.
