How do you melt toffee?

I melted toffee bits (~2 tablespoon) by first processing it in a coffee grinder to fairly fine powder, then pouring the toffee powder into a pre-warmed nonstick pen having a small amount (teaspoon) of water, over low heat, and mixing it gently but thoroughly while it bubbled up. I used it to coat crunchy soup noodles (chow-mein) for building a bird's nest as a wedding cake decoration.
