In the bowl of a standing mixer with the paddle attachment, 1 cup unsalted butter and 3/4 cup powdered sugar. Mix until combined.
Add 1 egg and 1/4 cup honey. Mix until combined.
Pour the dry ingredients on top: 2 1/3 cups all-purpose flour and 1/2 tsp fine sea salt.
Chop or smash the 1 cup of pistachios and fold into the dough.
Roll the dough out on a lightly powdered sugared countertop. Cut out shaped cookies and place them on three light-metal colored cookie sheets lined with parchment paper.
Bake for 10-15 minutes depending on how crunchy you like your shortbread. If you like them undercooked, get them out at 10 minutes. If you like a crunch, get them out at 15 minutes.
Let the cookies sit on the hot cookie sheet for 5 minutes before removing them and allowing them to fully cool. Enjoy!
