These no-bake cornflake chocolate fudge bars layer a chewy chocolate-cornflake base with a glossy fudge topping. Melt butter, condensed milk and chocolate together, fold in cornflakes, press into an 8x8 pan, chill. Finish with a hot cream-melted chocolate ganache, chill until set, then slice. Add nuts or sprinkles for variation and store airtight.
The summer I turned twenty three my roommate Sarah left a box of cornflakes on the counter for three weeks straight because neither of us ate breakfast cereal. One thunderous evening stuck indoors I melted chocolate chips into the sad leftover flakes and pressed the whole mess into a pan out of pure boredom. Two hours later we were fighting over the last bar.
I brought a tin of these to a potluck once and watched a quiet accountant named Greg eat five of them while pretending to browse his phone near the dessert table.
Ingredients
- 3 cups cornflakes: The cheaper the better here since fancy flakes crumble into dust when you fold them through warm chocolate.
- 1 cup semisweet chocolate chips for the base: Semisweet gives you that deep cocoa flavor without tipping into cloying territory.
- 1/2 cup unsalted butter: You will use another 2 tablespoons later for the topping so keep it measured and ready.
- 1/2 cup sweetened condensed milk: This is the binding magic that holds every crunchy bite together without baking.
- 1/4 cup granulated sugar: Just enough to round out the sweetness alongside the condensed milk.
- 1/2 teaspoon vanilla extract: Always real vanilla if you have it because the ingredient list is so short every flavor shows.
- Pinch of salt: Salt wakes up chocolate like nothing else so do not skip this.
- 1 cup semisweet chocolate chips for the fudge topping: This second cup gets melted with cream into a glossy blanket over the bars.
- 1/4 cup heavy cream: The cream transforms plain melted chocolate into something that sets with a truffle like softness.
- 2 tablespoons unsalted butter for the topping: Adds shine and helps the fudge layer slice cleanly without cracking.
Instructions
- Prep your pan:
- Line an 8 by 8 inch baking pan with parchment paper leaving enough overhang on two sides to lift the whole slab out later.
- Melt the base:
- Set a large saucepan over low heat and melt half a cup of butter until it just barely bubbles then pour in the sweetened condensed milk and sugar stirring gently until the sugar fully dissolves and the mixture looks uniform.
- Add the chocolate:
- Pull the pan off the heat and stir in one cup of chocolate chips vanilla extract and the pinch of salt until the chocolate melts completely into a thick glossy puddle.
- Fold in the cornflakes:
- Pour the cornflakes in and use a spatula to fold them through the chocolate with a light hand so you keep some of that beautiful crunch intact.
- Press into the pan:
- Transfer the coated cornflake mixture into your lined pan and press it down firmly and evenly using the back of a spoon or your palm.
- Make the fudge topping:
- Combine the remaining cup of chocolate chips heavy cream and two tablespoons of butter in a microwave safe bowl then microwave in twenty second bursts stirring between each until you have a smooth satiny ganache.
- Spread and chill:
- Pour the fudge topping over the cornflake base and spread it out evenly with your spatula then slide the pan into the refrigerator for at least one full hour until the top is set firm to the touch.
- Slice and serve:
- Lift the whole block out using the parchment overhang and cut it into sixteen squares with a sharp knife wiped clean between cuts for neater edges.
The year my neighbor broke her wrist I left a plate of these on her porch with a sticky note and she called me that night to say they were the only good thing about having to ask her teenager to open jars for a month.
Fun Ways to Dress Them Up
Stir a quarter cup of chopped roasted peanuts or dried cherries into the cornflake base before pressing it into the pan and you suddenly have a completely different bar every single time.
Storing Your Leftovers
Keep the bars in a single layer in an airtight container at room temperature for up to three days or stacked between sheets of parchment in the fridge for five days.
Getting Clean Professional Cuts
Let the chilled slab sit on the counter for ten minutes before slicing so the fudge softens slightly and your knife glides through instead of dragging.
- Use a long straight blade rather than a serrated one for the neatest edges.
- Wipe the blade with a damp cloth between each cut.
- Save the end pieces for yourself because they have the best ratio of crunchy edge to fudge top.
Every now and then the simplest dessert you throw together from pantry odds and ends becomes the one people request by name at every gathering. Keep a box of cornflakes around and you are never more than an hour away from proving that point.
Recipe FAQs

-
Coat the cornflakes quickly and press the mixture evenly so excess moisture is minimized. Chill fully before cutting and store bars airtight at cool temperature to preserve crunch.

Yes. Semisweet gives balanced sweetness, dark adds intensity and milk gives a milder, sweeter finish. Adjust sugar or condensed milk slightly if using very sweet chocolate.
