The things I love about these brownie bars!
- Easy to make – there’s two recipes in this dessert bar. An easy brownie layer, and a no-bake caramel crunch layer.
- Chewy, rich and crunchy! – the cornflake caramel layer is so delicious! The brownie layer is rich and chewy.
- Perfect for bake sales – these will sell better than hotcakes!
- Kids and adults will love them! The flavors are basic but so delicious. I gave Zoe a little piece and she would not leave the kitchen unless I have her more.
- Not too tall so they’re easy to eat! I think moving forward, this will be a focus for future bar recipes!
Let’s Talk Toffee
There are 3 things I learned about making toffee that I want to share with you. If you’ve never made a dry toffee before (no water), it’s actually super easy to make and it tastes delicious! In this recipe it’s what binds everything in the cornflake layer and helps it set.
- It can burn easily – don’t take your eyes off the toffee when making it. Cook on a medium low heat. Take your time. As soon as the sugar is melted take it off the heat and move to the next step immediately.
- Stir very gently and slowly – a rigorous stir can cause sugar crystals to stick to the sides of your pot and they will burn or can cause your toffee to crystalize (turn into a big, solid sugar crystal).
- Cook on a low, slow heat – there’s no speeding up this part of the recipe. It will take about 10 minutes to make the toffee. A low and slow heat will give the sugar time to melt and brown gently without burning.

Brownie Layer
- Brown sugar – I used regular brown sugar. You can use light. I would not recommend using dark brown sugar.
- Caster sugar – also known as superfine sugar is what I used but you can use granulated sugar as a substitute.
- Butter – I used salted butter, but you can use unsalted butter if you like.
- Dark chocolate – for this recipe, it’s important to use a good quality cooking chocolate. Cooking chocolate is specifically designed for baking and can be found in the baking isle of your supermarket.
- Eggs – I used large eggs. Make sure they’re at room temperature! Don’t skip the egg yolk either because it helps make the brownie chewier!
- Flour – I used all-purpose flour.
- Cocoa powder – I used Dutch process cocoa powder, but natural will work too.
- Vanilla extract – much to my surprise you can taste the vanilla in the brownie layer which makes it even richer!
Cornflake Layer
- Sugar – I used granulated sugar. See my notes above for my notes on making the toffee layer.
- Heavy cream – make sure your heavy cream (cream used for whipping) is hot before adding to the melted sugar otherwise it will splatter and overboil!
- Butter – I used salted butter.
- Vanilla Extract – Always use good quality vanilla extract when baking, it makes a huge difference. I have a great recipe here for it if you’d like to try your own!
- Cornflakes – I used kellogs cornflakes. Anything similar will work.

Tips and Tricks For Recipe Success!
- Don’t skip the egg yolk! The egg yolk helps make these brownies richer and chewy. It’s a remarkable thing and works with cookie recipes too!
- Store these in an airtight container for up to 5 days. They get chewier everyday!
- Bake the brownie layer up to a day in advance.
- When making the toffee, don’t take your eyes off it! It will burn easily. As soon as the sugar is melted and looks golden, take it off the heat and go to the next step.
- Chill time is important when setting the cornflake layer to make it easier to slice up.

Chewy Caramel Crunch Brownies
Serves 20
Ingredients
Brownie Layer
- 100 g brown sugar
- 105 g caster sugar, superfine
- 100 g salted butter
- 160 g dark cooking chocolate, chopped (see notes)
- 2 large eggs, room temperature (55g each)
- 1 egg yolk, see notes
- 115 g all-purpose flour, plain flour
- 25 g cocoa powder, sifted
- 7 g vanilla extract
Cornflake Layer
- 315 g granulated sugar
- 250 g heavy cream, hot
- 125 g salted butter, cut into pieces
- 1 tsp vanilla extract
- 200 g cornflakes
Instructions
Fudgy Brownie Layer
- Preheat your oven to 170C / 350F (190C / 375F for no fan). Spray a 23 x 33cm / 9 x 13-inch baking tin with oil spray and line the bottom and sides with baking paper leaving some overhang to make getting the slice out easier. I use bulldog clips to help keep the paper down as the brownies bake.
- Heat sugar and butter – Add the brown sugar, white sugar, salted butter and chopped chocolate to a heatproof bowl and microwave for 30 seconds at a time. Use a whisk to stir each time until melted and smooth.
- Whisk in eggs – Add the eggs and egg yolk and whisk until combined before adding the flour, cocoa powder and vanilla extract and mix.
- Bake – Pour into your prepared baking tin. Bake for 25 – 30 minutes. Allow to cool down to room temperature.
Cornflake Layer
- Make toffee (go slow!) – Add the sugar into a large sized saucepan and cook over low medium heat. Gently stir with a wooden spoon before letting it come to a boil. Then continue cooking until the toffee becomes a rich golden color and reaches 118C / 245F. Keep your eyes on it and take care not to burn the sugar which can happen very quickly!
- Add cream and butter and cook again – Add the hot cream and stir slowly until fully incorporated, then add the butter and continue stirring until well combined. Once mixed in, continue cooking on high heat for 5 minutes or until the caramel reaches a temperature of 120C / 250F.
- Stir in cornflakes and top – Remove from the heat and add the cornflakes. Gently fold through using a wooden spoon until all the cereal is coated. Pour on top of the brownies and spread out.
- How to set – Allow the slice to set at room temperature for about 30 minutes, then place in the fridge for 2 hours to chill until completely set. This will make slicing it up easier.
- How to get perfect slices – Use a large, sharp knife to slice into 4 x 5 squares. To make slicing much easier, run a sharp knife under hot water and dry it before cutting. This will help you get cleaner cuts through the sticky cornflakes layer. Serve chilled or at room temperature.
Notes
- It can burn easily – don’t take your eyes off the toffee when making it. Cook on a medium low heat. Take your time. As soon as the sugar is melted take it off the heat and move to the next step immediately.
- Stir very gently and slowly – a rigorous stir can cause sugar crystals to stick to the sides of your pot and they will burn or can cause your toffee to crystalize (turn into a big, solid sugar crystal).
- Cook on a low, slow heat – there’s no speeding up this part of the recipe. It will take about 10 minutes to make the toffee. A low and slow heat will give the sugar time to melt and brown gently without burning.

I can’t wait to try these!
Hey Janet! So excited for you to give these a go! You’re going to love the mix of fudgy brownies and crunchy caramel. Let me know how they turn out! N x
I’ve seen this very recipe on cupcake Jemma website. And why do you need my name and email address to comment!!!!!!!!!🤷🤷🤷
Yeah I know. I copied her. Please screenshot this reply and send it to her. Her first response will be that she invented this recipe and that I’ve copied her lol
Is the caramel chewy or crispy?
Hey Dala! The caramel is perfectly chewy, giving you that satisfying bite alongside the fudgy brownies and crunchy cornflakes. N x
Do the cornflakes stay crispy inside the toffee as the days go on? Or do they get stale/soggy/soft? I’m wanting to make these, but I know (I shouldn’t 🫣) go through them in a day or two and don’t like that kind of cereal texture if it doesn’t stay crispy.
Hi Lauren! I’d say these stay fairly fresh in an airtight container for about 3 days. N x
Too much toffee topping in relation to the brownie making it overly sweet for me. Next time I will make half the amount of topping and add some salt to combat the sweetness
Thanks for the feedback Lisa! N x
Do you think it would be weird if I changed the cereal? And it should be the same weight, right?
Not at all! Just be carefull with multi colored cereal which will make your batter grey in color. And yes, it would be the same weight! N x
