This recipe for Biscoff spread blondies does not have white chocolate in it. This is a personal choice - I find white chocolate a bit too sweet with the Biscoff spread. If you want to add chocolate, you can certainly include some by stirring chips or chunks into the mixture after step 4 (before pouring into the prepared baking tin). I'd recommend about 4 oz of chocolate for this mix. That said, I recommend these Biscoff blondies without white chocolate!
