Put the Biscoff biscuits into a sandwhich bag and twist the top to stop the biscuit from coming out.
Crush the biscuits in the bag with a rolling pin to form crumbs. You can also place the biscuits in a bowl and use the end of the rolling pin or similar to crush the biscuits.
Once you have crumbs, tip them into a mixing bowl, add the cream cheese and biscoff spread and mix well. The mixture will start to to stick together.
Take a spoon full of the mixture, roll into a ball and place on a tray/plate lined with baking paper. Repeat this with all the mixture.
Melt the white chocolate either in the microwave or by using a double boiler.
Once the chocolate has melted, add the Biscoff spread and mix well.
Using 2 forks, dip a truffle into the chocolate mixture ensuring the whole truffle is covered. Allow some of the chocolate to drip off before placing back on the baking paper. Repeat this with all the truffles.
Using a little extra crushed biscuits, sprinkle on to the top of the truffle.
Place the truffles in the fridge for about an hour.
Store in the fridge.
