Place the condensed milk, butter and 150 grams / 1 ½ cups of the coconut into a saucepan on medium heat.
Stir constantly until the butter has melted and the temperature has reached 100C/212F mixture has thickened and is no longer sticking to the edges of the saucepan.
Pour the mixture into a bowl so as to ensure it doesn’t keep cooking.
Toss in the crushed biscuits and stir until fully combined.
Place in the fridge to chill for at least 1 hour.
Remove and roll into balls.
Place the remaining desiccated coconut into a small shallow bowl or plate and roll a coconut ball through to coat fully.
Set aside and continue until all your coconut balls are coated.
Place into the fridge for 1 hour.
Remove and serve alongside a cup of your favorite hot beverage.
Enjoy!
