Hazelnut Toffee

Directions

1. 1
   1. Spread the chopped nuts on a cookie sheet and toast in 350 deg F oven for 10-15 min, stirring often. Watch carefully so they don't burn.

   4. Remove the pot from the heat and add the vanilla (if using it), then the nuts. Stir the mixture very well. You can place the pot back on the burner set to low to mix.

   5. Spread the toffee on a cookie sheet (I like to have parchment on the sheet but you don't have to). A rubber spatula helps to push the toffee out flat and evenly.

   6. Melt the chocolate chips in the microwave, 30-45 sec at a time, stirring well each time until just melted and smooth. Spread this on top of the toffee.
