Preheat oven to 375°F. Line a baking sheet with parchment paper or a Silpat.
Mix together the first seven ingredients and blend until smooth. I did this with a spoon.In a separate bowl combine remaining ingredients, except chunks; then combine with pumpkin mixture.
Add chocolate chips or chunks.Drop onto sheets in tablespoon sized drops.
Bake for 8-10 minutes (mine took 10).
Let cool completely on a rack, then make the glaze.In a mixing bowl or large microwave-safe liquid measuring cup, melt the butter.
Add the sugar and stir until mixture is like thick dirt, then add cream 1 tablespoon at a time until the mixture is about the consistency of Elmer’s glue. Spoon it over the cookies. You can let the icing set at room temperature or speed things up a bit and throw it in the refrigerator.
