Preheat your oven to 350°F. Lightly grease (or line with parchment) two baking sheets. For bars, lightly grease a 9" x 13" pan., In a large mixing bowl, combine the oil, sugar, baking powder, baking soda, spices, salt, vanilla, and egg, beating until smooth., Add the boiled cider or syrup., Stir in the carrots, cranberries, chips, and nuts, then the flour, beating gently until well combined., Add the oats last, making sure they're thoroughly distributed throughout the bowl., To make cookies: Drop tablespoon-sized balls of dough onto the prepared sheets, leaving about 1 1/2" between them., Bake the cookies until they're just barely set on top — about 12 minutes., Remove them from the oven, and cool them on the baking sheets; they'll be very soft, so don't try to transfer them to a rack., To make bars: Press the dough into the prepared 9" x 13" pan., Bake the bars for 25 minutes, until a toothpick inserted into the center comes out clean., Remove the bars from the oven, and press them down gently but firmly in the pan; this will make them slightly chewier. Serve them right out of the pan., Once cooled and cut, store in a covered container, with waxed paper or parchment between the layers to keep cookies or bars from sticking to one another.
