So here it is:
See the link for complete instructions, but here's the gist...
Melt the following over low heat:
1 bag of chocolate chips
3/4 bag of some other kind of chips (butterscotch, peanut butter, white chocolate, mint)
1 can sweetened condensed milk
Stir in some vanilla. Add (or not) nuts, craisins, etc. Follow instructions on the link to make into a wreath, using the empty condensed milk can. Very cool, and impressive.
The only thing I do differently is put it in a springform pan which makes it a whole lot easier to transfer to plate whole (which means it still looks like a wreath vs. cutting it up into delicious pieces). I did use a regular cake pan per the instructions when I made it today and I just had to cut the wreath in half to get it out of the pan, and put it back together. It will still be delicious.
Warning: the recipe says it makes 2 lbs or 32 servings. It always makes AT LEAST 2 lbs. on my hips and rear end.
