Ingredients

Base

300 g digestive biscuits or graham crackers, finely crushed (about 3 cups crumbs)
2 tbsp unsweetened cocoa powder
150 g (10 tbsp) unsalted butter, melted
3 tbsp light corn syrup or honey (for binding)

Hazelnut filling

250 g white chocolate, chopped
60 g (4 tbsp) unsalted butter
200 g hazelnut spread (smooth; e.g., a “milk & hazelnut” style spread)
120 ml (1/2 cup) heavy cream, warm
1 tsp vanilla extract
Pinch of salt
80–100 g crispy wafer sticks/biscuits, roughly crushed (about 1–1½ cups loose pieces)

Chocolate topping

250 g milk chocolate, chopped
1 tbsp neutral oil (for a soft bite)
60–80 g white chocolate, melted (for drizzle)

Optional garnish

Extra wafer shards, chopped roasted hazelnuts, or a few squares of Kinder-style chocolate

How to Make Kinder Bueno Slice

1) Line the pan

Line an 8-inch (20 cm) square pan with parchment, leaving overhang for easy lifting.

2) Make the base

In a bowl, mix biscuit crumbs, cocoa, melted butter, and corn syrup/honey until evenly moistened. Press firmly into an even layer in the pan. Refrigerate while you make the filling.

Tip: Pack it tight (use a flat-bottom glass) so it doesn’t crumble when sliced.

3) Make the hazelnut filling

Melt white chocolate and butter together (microwave in short bursts or over a bain-marie), stirring smooth. Whisk in warm cream, hazelnut spread, vanilla, and a pinch of salt until glossy and combined.

Fold in crushed wafer pieces (leave some bigger for crunch). Spread the filling over the chilled base; smooth the top. Chill 20–30 minutes to begin setting.

4) Add the chocolate topping

Melt milk chocolate with 1 tbsp oil until smooth. Pour over the set filling and tilt the pan to cover. Tap gently to remove bubbles.

Drizzle thin lines of melted white chocolate across the surface; drag a toothpick lightly back and forth to create a Bueno-style pattern (optional). Chill 1–2 hours until fully set.

5) Slice and serve

Lift out with parchment. Warm a sharp knife under hot water, wipe dry, then cut into neat bars or squares. Wipe the blade between cuts.

Serving Suggestions

Serve small squares on a platter for parties.
Add a dollop of lightly sweetened whipped cream and a few hazelnuts.
Pair with coffee, hot chocolate, or a cold glass of milk.

Cook’s Tips

Room-temp slicing: Let the slab sit 5–10 minutes out of the fridge for cleaner cuts.
Don’t pulverize wafers: A mix of fine and chunky bits gives the best texture.
Oil in chocolate: A tiny bit of neutral oil keeps the top from shattering.
Sweetness control: Use semi-sweet chocolate on top if you prefer less sweet.
Allergy swap: For nut-free, use a chocolate cream spread and skip hazelnuts (flavor will differ).

Variations & Add-Ins

Dark chocolate top: Use 70% chocolate for a richer finish.
Extra nutty: Fold in chopped roasted hazelnuts with the wafers.
Caramel ripple: Drizzle a few spoonfuls of thick caramel over the filling before topping with chocolate and swirl lightly.
Bigger tray: Double ingredients for a 9×13-inch pan.

Storage & FAQ

Storage: Refrigerate airtight up to 5–6 days. For firmer texture, keep well-chilled.
Freezing: Freeze in a single layer, then bag; thaw in the fridge (texture of wafers softens slightly).
Crumbly base? Add 1–2 extra tbsp melted butter if your crumbs are dry.
Soft topping? Chill longer; if your kitchen is warm, slice straight from the fridge.
