Homemade KitKat-Style Chocolate Wafer Bars

A crisp, light wafer stack coated in snappy chocolate for that classic “break” and melt-in-your-mouth crunch.

Ingredients

• 120g (1 cup) all-purpose flour
• 35g (1/3 cup) cornstarch
• 80g (2/3 cup) powdered sugar (icing sugar)
• 1/2 tsp fine salt
• 1/2 tsp baking powder
• 120g unsalted butter, cold and cubed
• 1 large egg
• 1 tsp vanilla extract
• 2–4 tbsp milk (as needed)
• 60g (about 1/3 cup) granulated sugar
• 60g water
• 2 tbsp honey (or golden syrup/corn syrup)
• 1/4 tsp fine salt
• 250–300g milk chocolate, chopped (or chocolate chips)
• 1 tbsp neutral oil (optional, for smoother coating)

Method

• 1

  Step 1: Make the wafer dough

  Heat oven to **170°C / 340°F (160°C fan)**. Line a **rimmed** baking tray (about **30 x 40cm / 12 x 16in**) with baking paper. In a bowl, whisk **flour, cornstarch, powdered sugar, salt, and baking powder**. Rub in the **cold butter** with fingertips (or pulse in a food processor) until it looks like fine crumbs. Add **egg and vanilla**, then mix just until it starts clumping. Add **milk 1 tbsp at a time** only until the dough holds together when pressed (it should be firm, not sticky).

  Step 2: Roll thin and bake

  Place dough between two sheets of baking paper and roll into a thin rectangle **about 2–3mm** thick. Peel off the top paper, transfer to the lined tray, and dock all over with a fork (helps it bake crisp). Bake **16–18 minutes** until **dry and lightly golden at the edges**. Cool completely on the tray (it crisps as it cools).

  Step 3: Make the “KitKat-style” syrup glue

  In a small saucepan, combine **granulated sugar, water, honey, and salt**. Bring to a boil over medium-high, then simmer **2–3 minutes** until slightly thickened and glossy (you’re aiming for a light syrup that will set, not caramel). Remove from heat and let cool **5 minutes** so it’s hot but not scalding.

  Step 4: Cut and stack the wafers

  Trim the baked wafer sheet into neat rectangles, about **3 x 9cm (1¼ x 3½in)** (or your preferred bar size). You’ll make **3-layer stacks**: brush a thin layer of warm syrup onto one wafer, press another wafer on top, brush again, then add the third wafer. Press gently but firmly so they adhere without cracking. Repeat to make **12 bars**. Refrigerate **20 minutes** to set.

  Step 5: Seal and chill (key for crunch)

  Brush a very thin coat of syrup over the outside of each stack (top/sides) to help the chocolate bond and to mimic that slightly “sealed” wafer bite. Chill again **20 minutes**.

  Step 6: Melt the chocolate

  Melt **milk chocolate** (and **oil**, if using) in a heatproof bowl in 20-second bursts in the microwave, stirring between, until smooth. Let it cool **2–3 minutes** so it’s fluid but not piping hot (hot chocolate can soften wafers).

  Step 7: Coat the bars

  Place bars on a rack set over a tray (or on baking paper). Spoon chocolate over each bar to fully coat, nudging chocolate along the sides. Tap the rack gently to smooth. For cleaner edges, you can scrape excess pooling with a small spatula.

  Step 8: Set and serve

  Let set at cool room temp **30–45 minutes**, or refrigerate **10–15 minutes** until firm. For the best “snap,” rest at room temp **10 minutes** before eating. Slice in half to get that classic break.

Tips

• **Thin wafers = authentic crunch:** Aim for **2–3mm**; thicker wafers turn more like shortbread.
• **Chocolate choice:** Milk chocolate is classic, but **dark chocolate** gives a sharper snap and less sweetness.
• **No honey/syrup?** Use **corn syrup** or **golden syrup**; the invert sugar helps prevent graininess and keeps the “glue” pliable.
• **Keep wafers crisp:** Avoid coating with very hot chocolate; let it cool slightly before dipping.
• **Storage:** Store airtight at **cool room temperature** for **5 days** (best crunch), or refrigerate up to **2 weeks** (let stand 10 minutes before eating). Freeze **2 months**; thaw unwrapped to avoid condensation softening the wafers.
• **Serving idea:** These are excellent with **coffee or a cold glass of milk**—the wafer really shines when slightly warmed in the mouth.
