This is a fun recipe from Allrecipes.
1 c. butter, softened
1 c. confectioners' sugar
1 egg
1 t. almond extract
1 t. vanilla extract
2 2/3 c. flour
1 t. baking powder
1 t. salt
whole almonds
red decorating gel
Combine the butter, sugar, egg, almond extract and vanilla extract in a bowl. Beat together with an electric mixer, gradually adding the flour, baking powder, and salt. Refrigerate for 20-30 minutes. Scoop 1 heaping teaspoon of dough at a time onto a piece of waxed paper. Roll the dough into a thin, finger-shaped cookie. Press 1 almond into one end of each cookie to give the appearance of a long fingernail. Shape the knuckles and cut wrinkle lines in each finger. Bake for 15-18 minutes in a 325° oven. After baking, remove each almond, squeeze a small amount of red gel into the cavity, and replace the almond to cause the gel to ooze out around the almond.
