Actually, it should chill for an hour or two. By four minutes I mean how long it takes to get in the fridge.
Completely line 8×8 pan with waxed paper.
Put the following in a microwave safe bowl and zap for 30-45 seconds:
3 cups of chocolate chips
1 can (14 oz) sweetened condensed milk
Dash of salt
After zapping, stir and hopefully all your chips have melted. Add in 1 1/2 teaspoons of vanilla and dump the delightful mess into the pan. Stick in the fridge for as long as you can stand it.
Why does everyone think fudge is hard to make?
