Preheat oven to 170C. Line a baking dish with baking paper.
Add all ingredients except raspberries & choc chips to a food processor or high speed blender and blend until really smooth.
Stir through Raspberries & choc chips then pour into your baking dish.
Bake for 50-60 mins until browned on top. Remove from the oven and allow to cool to room temperature. I like to pop mine in the fridge to cool completely and set before slicing but I totally get your need to dry this delicious gooey blondie while it's still warm so you do you.
