Using your paddle attachment, mix together butter, vanilla, and powdered sugar. Try not to whip in too much air.
Add in the eggs, mix until combined.
Add in the flour, mix until sandy.
Finish mixing the dough together by hand, kneading a bit to pick up the floor left on the bottom of the bowl.
Divide in two and wrap in plastic.
Let chill in the fridge for at least 1 hour before use.
Once chilled roll out into a thin circle and press into a tart pan. I prefer a tart pan with a removal bottom but you can use what you have on hand.
Chill the lined pan in the fridge until ready to use
