This recipe is so simple it should be one of my KISS recipes.  It consists of just 4 ingredients and is easy to change.  As you can see with my shortbread I added walnuts to some.  You can also make a finger indention and add a little preserves before baking, lightly press in a piece of chocolate, or change the nuts to pecans.  You can also use different non-dairy creamers for different flavors.  Just make sure they are the powdered type.
