STEP-1
Whisk eggs, oil, sugar, and extract in a mixing bowl. Stir in flour, baking powder, and salt.
STEP-2
Roll dough by tablespoonfuls into balls. Chill dough balls for at least an hour, or freeze for 15-20 minutes. Place cold dough balls on cookie sheets lined with parchment paper.
STEP-3
Bake at 350°F for about 9 minutes, or till the tops are set. Bottoms will be lightly browned, but tops should still be white. Remove cookies to cooling racks and cool completely.
STEP-4
For the glaze, combine all ingredients in a small bowl and whisk till smooth, adding enough warm cream to get a thin but creamy consistency.
STEP-5
Dip the tops of the cookies in the glaze, then top them with Christmas sprinkles.
