Tangerine Cranberry Oatmeal Cookies

Heat the oven to 350 degrees F. Line 2 large sheet pans with parchment paper. In a medium bowl, combine the oats, flour, baking soda, salt and tangerine zest and toss to combine. In a large bowl cream the butter. Add the brown sugar and beat until light and fluffy, about 2 minutes. Add the egg and beat until combined. Beat in the tangerine juice and vanilla; the mixture will appear to have curdled slightly. Stir in the flour mixture until well-mixed, then stir in the cranberries.

Form heaping tablespoon-sized portions of dough and place on the sheet pans, about 3 inches apart. Don't flatten the cookies — they will spread on their own. Bake for 6 minutes, then rotate the pans, reversing their positions in the oven. Bake for 6 minutes longer. Cool for at least 5 minutes before using a spatula to transfer the cookies to the racks to finish cooling completely. Repeat the baking process with the remaining dough.

These cookies keep, tightly covered, for up to a week at room temperature.
