Preheat oven to 400 degrees.
In mixing bowl, combine butter and sugar. Blend well.
Add in egg and vanilla to combine well.
Gently stir in the flour and salt.
At this point, divide dough into equal portions. Depending on the Holiday, use food coloring to color match the Holiday. For Christmas, I use green, red, and leave a portion plain and I use Holiday spritz cut-outs.
Fill the cookie press according to manufacturers instructions.
Use desired shapes and press on an ungreased cookie sheet.
Decorate with your colored sugars and sprinkles.
Bake until set. I have never gone past 6 minutes.
Move cookies to cooking rack to cool. Can be frozen for about 1 month.
