Step 1

Preheat your oven to 180C/160C Fan and line a 9x9" square tin with parchment paper.

Step 2

In a large bowl, add your melted butter and sugars and beat till smooth.

Step 3

Add in the eggs and vanilla and beat again till smooth.

Step 4

Add in the flour and cornflour and beat till a thick blondie mixture is made - it really doesn't take long to create this mixture!

Step 5

Add in your white chocolate and fold through!

Step 6

Pour the mixture into the tin, and spread. Dollop on the biscoff spread and lightly swirl through the blondie mixture.

Step 7

Sprinkle on the chopped biscuits!

Step 8

Bake the Blondies in the oven for 25-30+ minutes, or until there is a slight wobble in the middle. (See notes below)

Step 9

Leave to cool in the tin, or on a wire rack.

Step 10

As an optional extra, you can 'set' your blondies in the fridge for an hour or so to help with the texture! ENJOY!
