In a microwave safe bowl, melt chocolate with butter. Or melt it over steaming water. Let cool.

Preheat the oven to 180C. Line a 14x14cm pan with parchment paper and set aside.

In a separate bowl, whisk eggs, light brown sugar and caster sugar with a handheld electric mixer for about 1 minute.

Pour in the melted chocolate and stir with a spatula. Add flour and cocoa powder and mix until just combined. Try not to over mix.

Pour half the mix into the pan and spread evenly. Add dollops of Lotus Biscoff spread on top and swirl it to the mix. Scatter broken cookies. Repeat all the steps with the rest of the mix.

Bake for 28 mins with fan or until a toothpick inserted comes out fudgy.

Let cool completely. Use a hot knife to cut into 9 squares and enjoy!
