The story behind this recipe
This recipe comes from a time when I needed a quick fix for a sweet craving, but didn’t want to turn on the oven or fuss too much. I remember making these bars with my grandma on lazy Sunday afternoons—her way of turning simple ingredients into something magical, almost like a secret code for happiness. It’s funny how a handful of cornflakes and melted chocolate can unlock so many childhood memories, and still feel just right in the chaos of today’s busy life.
Key Ingredients Breakdown
- Chocolate: I use good quality dark chocolate—melts smoothly and gives that rich, bittersweet flavor. You can swap with semi-sweet if you prefer less intense chocolate, but skip the overly sweet milk variety for this one.
- Cornflakes: The crunch is everything here. I like the plain, unsweetened kind—makes the bars less cloying. If you want a touch more sweetness, toss in a handful of crushed cookies or a sprinkle of brown sugar.
- Butter: I rely on unsalted for control—makes the chocolate richer and prevents over-salting. If you’re dairy-free, a neutral vegetable oil works, but it won’t add that lovely silky sheen or depth.
- Sweetener: Sometimes I add a dash of honey or golden syrup for a sticky, glossy finish. If you’re avoiding sugar, try maple syrup—just keep in mind it’s a bit more runny and can slightly alter texture.
- Optional add-ins: Nuts, dried fruit, or even a pinch of sea salt can elevate these bars. I love a handful of toasted almonds for that smoky crunch—go wild or keep it simple.
- Extras for flavor: A splash of vanilla or a pinch of cinnamon can add warmth. I tend to keep it classic, but don’t hesitate to experiment with spices for a cozy twist.
- Pan liner: I always line my pan with parchment—easy to lift the bars out and prevents sticking. For a cleaner look, a quick spray of non-stick spray works too.
Spotlight on key ingredients
Chocolate:
- I use good quality dark chocolate—melts smoothly and gives that rich, bittersweet flavor. You can swap with semi-sweet if you prefer less intense chocolate, but skip the overly sweet milk variety for this one.
- Cornflakes: The crunch is everything here. I like the plain, unsweetened kind—makes the bars less cloying. If you want a touch more sweetness, toss in a handful of crushed cookies or a sprinkle of brown sugar.
- Butter: I rely on unsalted for control—makes the chocolate richer and prevents over-salting. If you’re dairy-free, a neutral vegetable oil works, but it won’t add that lovely silky sheen or depth.
Cornflakes:
- They have a fragile crunch that softens slightly over time, but they hold their shape well. Toasting enhances their aroma and adds a smoky note that balances the sweetness.
- Chocolate: It melts into a glossy, smooth pool when warmed, then sets to a firm, snap-worthy finish. Watch for a faint shimmer—if it looks dull, it might need a bit more stirring or a slightly lower heat.
- Butter: It acts as a binder and adds a silky mouthfeel. During melting, keep the heat gentle to avoid seizing or burning, and you’ll get a smooth, oozy texture that coats the cereal perfectly.
Notes for ingredient swaps
- Dairy-Free: Swap regular butter for coconut oil or vegan butter. The texture remains rich, but the flavor gets a subtle tropical note.
- Chocolate: Use dairy-free dark chocolate or 70% cacao for a less sweet, more intense cocoa flavor. White chocolate can be substituted for a creamier, sweeter taste.
- Cornflakes: Rice Krispies or gluten-free crisped rice make decent substitutes. They add a lighter crunch but might alter the classic cornflake flavor.
- Sweetener: Honey or agave syrup can replace sugar and corn syrup for a sticky, fragrant sweetness. Keep in mind they can make the mixture slightly runnier.
- Add-ins: Nuts like chopped almonds or walnuts, dried fruit, or seeds can be mixed in. Toasted nuts add smoky depth, while dried fruit brings a chewy burst.
- Pan liner: Use aluminum foil or grease the pan well if you don’t have parchment. Expect a slightly messier removal and less clean edges.
Equipment & Tools
- 20×20 cm (8×8 inch) square pan: Holds the mixture and shapes the bars.
- Heatproof bowl: Melts chocolate evenly over simmering water.

Step-by-step guide to no bake bars
- Equip yourself with a 20×20 cm (8×8 inch) square pan, lined with parchment paper—this makes lifting out the set easier.
- Melt 200g (7 oz) of good-quality dark chocolate in a heatproof bowl over a pan of simmering water (bain-marie). Keep the heat gentle, just enough to melt, with a faint shimmer and no bubbling.
- While the chocolate melts, toast 50g (1.75 oz) of cornflakes lightly in a dry skillet over low heat, stirring until just fragrant—about 2 minutes. Cool slightly.
- Pour the toasted cornflakes into a large mixing bowl. Add the melted chocolate and 25g (1 oz) of unsalted butter. Gently fold until evenly coated, avoiding breaking the cereal.
- Transfer the mixture into your prepared pan. Use a spatula or the back of a spoon to press down firmly and evenly, ensuring no air pockets. The surface should be smooth and slightly shiny.
- Place the pan in the fridge for at least 2 hours, or until the mixture is firm and set—check for a clean crack when gently pressing in the center.
- Once set, lift the block out using the parchment paper. Use a sharp knife to cut into squares or rectangles. For cleaner cuts, wipe the knife with hot water between slices.
- Let the bars sit at room temperature for 10 minutes before serving to soften the chocolate slightly and bring out full flavor. Serve and enjoy!
Chill the bars in the fridge until firm, then lift out using parchment. Slice into even pieces, serve directly from the fridge or at room temperature. Store leftovers in an airtight container in the fridge for up to a week.

Prep, store, and reheat tips
- Prep the mixture ahead by melting the chocolate and preparing the cereal—this speeds up assembly later and keeps ingredients fresh and fragrant.
- Store the uncut, set bars in an airtight container in the fridge for up to a week. The chocolate will develop a slight sheen and firm texture.
- For longer storage, wrap the bars tightly in plastic wrap and freeze for up to a month. Thaw at room temperature for about 10 minutes before serving.
- Reheat slightly in the fridge or at room temperature to soften the chocolate just enough to enhance flavor and texture. Watch for a shiny, gooey surface.
- Avoid leaving the bars out in warm, humid environments; the chocolate can soften or bloom, losing its glossy finish.
