If you have to omit the nuts (allergy), do you need to add something in to replace it (e.g., extra oats or maybe chocolate chips)?

These sound so yummy, I need to make them, too! To answer your question, the recipe calls for a cup of pecans, so by leaving them out, you would lose not only a cup of the dough but also that nutty flavor, but I understand your dilemma. Yes, I would add another 1/2 to 1 cup of oats to the recipe, but the chocolate sounds like a great addition, too. You could also add some chopped dried or freeze dried fruit, think freeze dried raspberries with chocolate chips and raspberry jam, dried apricots with apricot jam, or dried apples and apple butter. You might want to toast that additional oatmeal in the oven to bring out the oatmeal's nutty flavor. Enjoy!
