Line a 9x9" square tin with parchment paper, and leave to the side.
Add the butter and mini marshmallows to a large pan, and heat on a low-medium heat, stiring, untill smooth and melted!
Once melted, take the pan off the heat and add in the biscoff. Stir briefly until smooth!
Pour the rice krispies into the pan, and stir to combine!
Press the mixture into the bottom of the lined tin (top tip, buttering your hands slightly can prevent any sticking and makes it easy to press down!)
Melt the white chocolate in a bowl until smooth - I do this in short bursts in the microwave stiring well each time.
In a separate bowl, melt the biscoff spread - This takes about 20 seconds in the microwave.
Pour the two over the rice krispie base and swirl together with a cake skewer.
Set in the fridge for two or more hours, and then slice and enjoy!
