- In top of a double boiler melt chocolate chips, stirring until smooth.
- Remove from heat; keep chocolate warm over water in the double boiler.
- Dip large ends of cooled cookies into melted chocolate, then roll in remaining 3/4 cup chopped pecans.

These are *really* good and pretty easy to make. My 3-year-old has been wanting to eat acorns, but I talked him into acorn cookies! He had a lot of fun helping with these. They don't spread out, so you can bake them pretty close together. Also, for us, 1/2 c ground pecans only covered a little more than half of the cookie tops. So we made some with just chocolate and no pecans. Yummy and cute!
