2210 Patisserie classic brownie with cornflake crunch topping

"At the bakery, I love to make classic sweet treats like brownies, blondies and biscuit cakes. But I like to put my own spin on things. This recipe is for classic brownies with a twist – a crunchy cornflake topping. Delicious!"

For the brownies: 

  • 4 eggs
  • 600g light brown sugar
  • 230g butter

Cornflake crunch topping

  • 4 mars bars
  • 120g butter
  • 120g cornflakes

For the brownies:
1. Preheat the oven to 170C
2. Prepare a 10" square baking tin with greaseproof paper 
3.  Whisk 4 eggs and 600g of brown sugar together until light and fluffy.
4. Melt the butter and chocolate together. On a low speed add the melted mixture into the whisked eggs and sugar. 
5. Add in the final ingredients, flour and cocoa powder, mix until fully combined. 
6. Pour brownies mixture into your lined baking tin and bake for 30-40 mins. (baking time will depend on the size of your tin and the oven). 
7. Brownies should be wobbly and soft in the centre when baked.

2. Pour mixture over the cornflakes and mix together until all the conflates are coated.
