I have made both healthy cookies from the new Moosewood cookbook. The butternut cookies were delicious, but more of a mini-muffin than a real cookies (of course, that could partly be because I swapped the 12 ounces of butternut puree called for in the recipe with a whole 14.5 ounce can of pumpkin puree). The oatmeal cookies were delicious, a little too delicious.
One change I think I would make to the oatmeal cookies is to bake them at a higher temperature than the 350 degrees suggested. I think 375 degrees would be much better. The oatmeal cookies came out rather pale when baked at 350 degrees. Also, I skipped the nuts and dried fruit and doubled down on the chips.
