Line your muffin moulds with paper cases and then fill with 5mm of blondie base.
Take to a preheated oven at 180C for 10min.
Whatever's left of dough flatten on a 20x20cm mould lined with baking paper and take to a preheated oven at 180C for 15min. Once cold cut into mini blondies.
Lower the speed of the machine to minimum and add the egg. Mix it in on low speed so as not to add air into it.
Fill the muffin paper cases with the mix and take to a preheated oven at 180C in a tray with boiling water. The water should go halfway up the cheesecakes.
Make a thin layer of sugar on a pan and put it on medium heat. As some spots start to melt cover them with a thin layer of sugar. Continue until you have used up all the sugar in the recipe.
Let it become a nice pale gold colour and don't use any utensil to mix at this point, only move around the sugar by tilting the pan
Once golden add the cream and whisk together vigorously. Be really careful because it's really hot and it will bubble up.
Once incorporated add the butter and salt and mix in.
Let it cool down completely.
Remove the paper from the cheesecakes and top with the mini blondies. Finish with a drizzle of salted caramel.
