Preheat your oven to 180°C and grease and line a 20cm square springform baking tray.
Add your melted dairy free butter, light brown sugar and granulated sugar to a large mixing bowl and whisk until fully combined.
Add the eggs and vanilla extract and whisk again until combined.
Add the flour, cornflour, xanthan gum and salt and beat again.
Fold in the dairy free white chocolate chips and then transfer the mixture to your baking tin.
Bake in the oven for around 35-40 minutes (this depends on your oven, but you want there to still be a slight wobble in the middle - you may need to bake them for slightly more or slightly less than the recipe states).
Remove from the oven and press the Nomo Reindeers (and additional chocolates/sprinkles - optional) into the top of the blondies.
Transfer to the fridge to cool and set completely before cutting and serving.
