Preheat your oven to 300, and use unlined, clean, baking sheets. In a large bowl, beat together the butter and cream cheese until smooth. Add in the sugar and vanilla extract, and beat until well combined. Scrape down your bowl, and then add in the flour and salt and mix until well combined. Scrape down your bowl again to make sure there are no pockets of unmixed dough.

Load the dough into your cookie press using any pattern you prefer, and press the cookies onto your unlined baking sheets. They don't spread much so you can put them right next to each other.

Sprinkle the cookies generously with your colored sugars and sprinkles before baking.

Bake for 15-18 mins or until just lightly golden brown. Cool completely on the pan before removing and enjoying!
