Instructions: Place crumbs in a mixing bowl and add sugar and cinnamon, then stir in butter. Butter an 8" springform pan on bottom and sides.

Sprinkle a thin layer of crumbs on the bottom of pan and press down with a metal measuring cup. Pat crumbs on sides of pan and press in place with side of measuring cup. Work around sides of pan with fingers to make crumbs of even height. Any remaining crumbs can be added to bottom crust. Bake crust at 350 degrees for five minutes.

To make filling, beat eggs until light. Add sugar and beat 5 minutes. Add cream cheese, vanilla, and Grand Marnier and mix well.

Turn into prepared crust. Protect exposed top edge of crust by folding strips of foil around the rim of the pan. Bake at 375 degrees for 20 minutes. Cool 15 minutes. Remove foil.

Blend sour cream, sugar, vanilla and Grand Marnier well, then pour over filling and bake at 475 degrees for 5 minutes. Cool cake and chill overnight before serving.
