Whichever one is in my hand at the moment!
I actually LOVE what seems to be the most unpopular cookie ever - oatmeal raisin. Yum! I love it when they have cookie trays at work because everybody wants the chocolate chip ones and I can have as many of the oatmeal ones as I want! LOL When I make them at home, I add little bits of dehydrated apple to the dough, so it's an oatmeal apple/raisin cookie...sooooo good!
