This tastes like a Heath bar.

1 cup (2 sticks) butter
1 cup granulated sugar
2 tablespoons water
1 tablespoon light corn syrup
1/2 cup chocolate chips
2/3 cup finely chopped nuts

Melt butter over low heat in saucepan. Add sugar and stir until melted. Add water and syrup. Continue cooking over low heat until syrup, dropped in cold water, becomes brittle (320 degrees F on a candy thermometer). Don't undercook. Remove from heat. Pour onto greased platter. This mixture should be thin. Cool until hardened.

Melt chocolate over hot water. Spread on crunch. Sprinkle nuts over top and pat in. Break into pieces.
