Step-by-step guide to perfect no-bake peanut butter bars

1. Prepare a 20×20 cm (8×8 inch) pan by lining it with parchment paper.
2. In a microwave-safe bowl, melt 1/2 cup (115g) butter in 30 seconds, until just liquid.
3. Combine 1 cup (250g) peanut butter, 1/2 cup (120ml) honey or maple syrup, and a pinch of salt in a mixing bowl.
4. Pour the melted butter into the peanut butter mixture, stirring until smooth and glossy.
5. Add 2 cups (200g) of crushed graham crackers or digestive biscuits; mix well.
6. Transfer the mixture into the prepared pan, pressing down firmly with a spatula to even out.
7. Melt 1/2 cup (90g) chocolate chips, then drizzle over the top for extra richness.
8. Chill in the fridge for at least 2 hours or until firm and set.
9. Check for doneness: the surface should be glossy, edges slightly pulled from the pan, and it should hold together when pressed.
10. Use a sharp knife to cut into bars, wiping the blade between cuts for clean edges.
11. Store in an airtight container; they keep at room temperature for 3 days or in the fridge for up to a week.

Let the bars rest in the fridge for at least 2 hours before cutting. Serve chilled or at room temperature, depending on preference.

How to Know It’s Done

Common mistakes and how to fix them

• FORGOT TO CHILL: Chill longer or re-freeze to firm up.
• DUMPED TOO MUCH OIL: Drain excess oil or add more dry ingredients.
• OVER-TORCHED CHOCOLATE: Use a double boiler or microwave in short bursts.
• NOT ENOUGH PRESSURE: Press mixture firmly into the pan to avoid crumbly bars.

Quick fixes to common issues

• When mixture is too sticky, add crushed biscuits or oats.
• Splash a little warm water on the chocolate to loosen it.
• Patch cracks by pressing in extra crumbs or melted chocolate.
• Shield edges with parchment if they crack during slicing.
