In a large bowl, you can use your hand mixer or stand mixer, mix the butter, sugar and vanilla together for 2 minutes. Once the butter and sugar is smooth, slowly add in the flour, mixing until just combined.

Stir in the chocolate chips evenly.

Transfer the dough to a zip-top bag and chill for at least 2 hours. I find that this makes it easier to roll the dough out and cut into shapes.

Preheat oven to 325°F. Line a baking sheet with parchment paper and set aside.

Remove dough from plastic bag, and roll dough out into a large square, 1/3-inch thick. Cut the dough into squares using a knife, or cookie cutters.

Place on baking sheet and bake for 18-20 minutes.  Remove and allow the cookies to cool.

Now is when you get to decorate.  Melt chocolate in a small microwave safe bowl by microwaving on high for 30 seconds at a time, stirring between. Dip cookies in chocolate covering 1/3 of the cookie and place on parchment paper, sprinkle with holiday sprinkles and allow chocolate to harden.
