Cut in butter as you would when making biscuits or a pie crust, using two knives or a pastry blender to mix until the dry mixture resembles coarse bread crumbs (some larger lumps can remain).

In a separate bowl, beat eggs and add sugar and vanilla. Combine the two mixtures. Refrigerate for about 15 minutes, then roll out and cut into desired shapes.

Bake for 8-10 minutes in a preheated 400°F oven.

Makes about 3 dozen.
