Preheat oven to 350 degrees F. For crust, in a small mixing bowl, combine crushed cookies, brown sugar, and melted butter. Divide crumb mixture evenly among sixteen 1-3/4-inch muffin cups. Press crumb mixture onto bottom and up sides of each cup. Bake in a preheated oven for 5 minutes.

Meanwhile, in a medium mixing bowl, beat together cream cheese, 1/4 cup of the marmalade, the egg yolk, and flour. Divide cheese mixture evenly among the muffin cups. Bake about 15 minutes more or until a knife inserted in the centers comes out clean. Cool cheesecakes in tins on a wire rack (centers will dip slightly). Remove from muffin tins. Top each cheesecake with about 1/2 teaspoon marmalade. Serve at once or cover and chill up to 24 hours.

Makes 16 servings

To make ahead: Bake cheesecakes as directed, but do not top with additional marmalade. Place cheesecakes in a freezer container. Cover, label, and freeze up to 3 months. Before serving, thaw overnight in refrigerator. Top with marmalade before serving.
