Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a large bowl, cream together the softened butter and powdered sugar until light and fluffy. Add the vanilla extract and continue to mix.

In a different bowl, whisk together the all-purpose flour and salt. Gradually add this mixture to the wet ingredients, stirring until just combined.

Fold in the finely chopped pistachio nuts into the cookie dough.

Using a cookie scoop or tablespoon, scoop the dough onto the prepared baking sheet, spacing them about 2 inches apart.

Make a small indentation in the center of each cookie dough ball and fill it with a dollop of pistachio cream.

Bake in the preheated oven for 10-12 minutes, or until slightly golden around the edges.

Once out of the oven, let them cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
