Here is a recipe that is very quick, tastes great and actually doesn't require you to turn the oven on (big ticks from me on that account). I can't remember where I got the recipe from, but I have been making this with my friends since I was in high school.
You need 3 ingredients - 1 box of chocolate tiny teddy biscuits, 1 can of sweet condensed milk, 1 cup of coconut (plus a bit extra for covering).
Crush biscuits in the blender, mix in a bowl with 1 cup of coconut.
Pour in the tin of sweet condensed milk, and mix together. Roll into balls, sprinkle and cover with the extra coconut. Place in the fridge to set for 1 hour or more.
Enjoy as a small bite to eat or serve with fruit as a dessert platter at your next special occasion!
