Mix wet ingredients. In a large bowl with a hand mixer, or a stand mixer with the paddle attachment, mix together butter, yogurt, and sugar until light and fluffy, about 4 minutes on medium speed.
Add final wet ingredients. Add the salt and vanilla. Mix again, scraping down the sides of the bowl.
Add the flour. Mix until dough just comes together.
Transfer and press. Transfer dough to a cookie press and press cookies onto an ungreased and unlined cookie sheet.
Chill. Place cookies on a tray in the fridge for 15 minutes.
Preheat the oven to 400°F/205℃.
Bake. Bake cookies in the oven for 8-10 minutes or until cookies are slightly golden brown on the edges. Be careful. These will burn very quickly!
Cool. Let the cookies cool on the tray for 10 minutes before transferring to a cooling rack to finish cooling. Enjoy!
