The story behind this recipe
- I first stumbled upon this recipe during a chaotic family picnic, where dessert options ran out fast and the kids were eyeing the chocolate stash. Making these bars became our emergency sweet, and surprisingly, they turned into a regular treat at home. The simplicity, the crunch, and that glossy chocolate finish somehow make everything feel a little more manageable after a hectic day.
- Every time I make these, I remember the mess of cornflake crumbs on the counter and the smell of melting chocolate filling the room—comfort in chaos. They remind me that sometimes, the best moments are the easiest, and that a good, honest treat doesn’t need fancy ingredients or fuss. It’s just about that perfect balance of crunchy, fudgy, sweet—and knowing you can whip it up quickly, no oven required.

Key Ingredients Breakdown
- Chocolate: I prefer a good quality semi-sweet or dark chocolate that melts smoothly and coats the cornflakes beautifully. If you only have milk chocolate, it’ll still work but might be a tad sweeter and less intense.
- Cornflakes: The crunch comes from the cornflakes, so I always use plain ones. Toast them lightly beforehand if you want extra toasted flavor or skip that for a softer crunch.
- Butter: A splash of butter helps melt the chocolate evenly and adds richness. If you’re dairy-free, coconut oil is a decent swap, but it might add a slight coconut aroma.
- Sweetener: Sometimes I add a pinch of sea salt or a drizzle of honey to enhance the chocolate flavor. Skip it if you prefer a straightforward sweet treat.
- Vanilla Extract: Just a teaspoon brings warmth and depth. If you’re out, a splash of almond extract can give a different, nutty twist.
- Optional Add-ins: Nuts, dried fruit, or even a sprinkle of sea salt on top can elevate the bars. Use your favorite mix-ins to customize your crunch.

Equipment & Tools
- 20×20 cm (8×8 inch) baking pan: To shape and set the bars.
- Parchment paper: For easy removal and cleanup.
- Microwave-safe bowl: To melt chocolate and butter gently.
- Spatula: To fold and press mixture evenly.
- Sharp knife: To slice the set bars cleanly.
Step-by-step guide to no-bake bars
- Gather all ingredients and equipment before starting to keep things flowing smoothly.
- Line a 20×20 cm (8×8 inch) baking pan with parchment paper, leaving some overhang for easy removal.
- In a large microwave-safe bowl, combine 200g (7 oz) of chopped chocolate and 50g (1/4 cup) of butter. Microwave in 30-second bursts, stirring in between, until smooth and glossy. Be careful not to overheat; the chocolate should be just melted.
- While the chocolate melts, measure 3 cups of cornflakes into a large mixing bowl. If you like a toasted flavor, lightly toast them in a dry pan over medium heat for 2-3 minutes until golden and fragrant, then cool slightly.
- Pour the melted chocolate mixture over the cornflakes. Use a spatula to gently fold, coating every flake without crushing them. The mixture should be shiny and evenly coated.
- Transfer the mixture into your prepared pan. Press down firmly with the back of a spatula or your fingers to create an even, compact layer. If the mixture is sticky, dampen your hands slightly to help with pressing.
- Place the pan in the fridge for at least 2 hours, or until the bars are firm and set. For quicker setting, pop them in the freezer for about 1 hour, checking for a firm, crackly top.
- Once set, lift the whole block out using the parchment overhang. Slice into bars or squares with a sharp knife. For clean cuts, wipe the knife between slices.
- Store the bars in an airtight container at room temperature for up to 3 days, or in the fridge for up to a week. They firm up slightly in the fridge, so let them sit at room temp for 10 minutes before serving for optimal texture.
Chill in the fridge for at least 2 hours or freeze for 1 hour until firm. Slice into squares and serve directly from the fridge or at room temperature for a softer bite.
How to Know It’s Done
- Chocolate is fully melted and smooth without lumps.
- Cornflakes are evenly coated and coated mixture is glossy.
- Bars are firm and hold shape when sliced, with a crackly top.

- Place the chopped chocolate and butter in a microwave-safe bowl. Microwave in 30-second bursts, stirring well each time, until the mixture is smooth and glossy.
- While the chocolate melts, measure out the cornflakes into a large bowl. If you like, lightly toast them in a dry skillet over medium heat until golden and fragrant, then let them cool.
- Pour the melted chocolate mixture over the cornflakes. Use a spatula to gently fold and coat every flake evenly, being careful not to crush them. The mixture should become shiny and well-coated.
- Transfer the coated mixture into your prepared pan. Press down firmly with the back of a spatula or your fingers to create an even, compact layer. Dampening your hands slightly helps prevent sticking.
- Place the pan in the fridge for at least 2 hours, or until the bars are set and firm. For quicker setting, pop it in the freezer for about an hour, checking that it’s firm and crackly on top.
- Once set, lift the whole block out of the pan using the parchment overhang. Slice into squares or bars with a sharp knife, wiping the blade between cuts for clean slices.
- Serve the bars immediately or store them in an airtight container at room temperature for up to 3 days, or in the fridge for up to a week. Let them sit at room temp for about 10 minutes before serving for the best crunch.
Pro tips for perfect bars
- Use high-quality chocolate for a glossy finish and rich flavor. Low-quality chocolate can seize or become grainy.
- Lightly toast cornflakes in a dry pan to deepen their flavor and add a smoky note before mixing.
- Stir melted chocolate in small bursts to avoid overheating, which causes seizing or burning. Cool slightly if needed.
- Press the mixture firmly into the pan to ensure the bars hold together and cut cleanly. Dampen hands for easier pressing.
- Chill the bars until fully set—at least 2 hours in the fridge—so they’re firm and easy to slice without crumbling.
- Use parchment overhang for easy removal and clean cuts. Wipe your knife between slices for smooth edges.
- For a shinier finish, gently warm the spatula before pressing the bars into the pan, creating a smooth surface.
Common mistakes and how to fix them
- MISSED melting point: Overheated chocolate seizes. Fix by stirring in small bursts and cooling slightly.
- DUMPED ingredients: Excessive cornflakes cause dryness. Use recommended amount for best texture.
- OVER-TORCHED chocolate: Burnt flavor ruins bars. Remove from heat immediately if smell turns smoky.
- TOO HARD when cooled: Bars feel brittle. Slightly under-set in fridge for a softer bite.
Quick fixes and pantry swaps
- When chocolate seizes, splash in a bit of warm cream to rescue smoothness.
- Dumped too many cornflakes? Add a touch more melted chocolate to balance crunch and fudginess.
- Over-torched chocolate? Immediately stir in a teaspoon of coconut oil to soften the burnt flavor.
- When bars are too hard, let them rest at room temp for 10 minutes to soften before slicing.
- Splash a few drops of vanilla extract on the mixture if it looks dull or lacks depth.
Prep, store, and reheat tips
- You can prepare the mixture a day ahead; keep it covered in the fridge to prevent drying out. The chocolate remains glossy and easy to work with, and the bars will set more flavorfully after resting overnight.
- Stored in an airtight container at room temperature, the bars stay fresh for up to 3 days, maintaining their crunch and fudgy texture. Keep them away from direct sunlight to prevent melting or softening.
- In the fridge, they last up to a week, but the chocolate can harden slightly and the cornflakes may soften. Let them sit at room temp for 10 minutes before serving to regain a bit of crunch.
- Reheating isn’t necessary; these bars are best served chilled or at room temp. If you want a softer, more melty chocolate, gently warm them in the microwave for 10 seconds—watch for a shimmer of shine, not grease.
