Mixed "unsalted butter" with "granulated sugar"

Add "egg yolks" and continue mixing

Add "vanilla extract" and continue mixing

Add "all-purpose flour" and continue mixing until well combined

Put the dough into piping bag and pipe as design

Store in the fridge for 5-10 minutes so they stay in the shape you desire

Bake at 160C for 12-15 minutes depends on your liking for me I like them a little brown

Let them cool on a rack for about 5 minutes before serving or bagging them

Extra step: add strawberry jam in to give it some color
