Ilene Danuff of New York, New York, writes: "This recipe was created by my mother. I've substituted chocolate chips for the M&M's MINIs that she uses."
Mandelbrot is a traditional Jewish cookie that resembles biscotti but is more tender. Claire Danuff sprinkles her cookies with cinnamon sugar before baking, but we prefer them plain. To try the topping, combine 1/4 cup sugar with 1/2 teaspoon cinnamon.
