Toffee Fondue

I love fondue!!! We just had a fondue girl's night, and I made a toffee fondue. It's a tasty little treat.

1/2 cup butter
2 cups dark brown sugar
1 cup white corn syrup
2 Tablespoons water
1 (14 ounce) can sweetened condensed milk
1 teaspoon vanilla extract

Melt butter in a bowl over a pan of hot water, and add all the other ingredients except the vanilla extract. Stir until thick, then add the vanilla extract. Place in a fondue pot to keep warm, and serve with pieces of apple, pear, banana, strawberry, rice krispie treat, angel food cake, or whatever else your heart fancies.
