1Preheat your oven to 325°F (165°C).
In a large bowl, cream together the unsalted butter and granulated sugar until light and fluffy.
Add the vanilla extract and instant espresso powder to the butter mixture and mix until well combined.
Gradually add the all-purpose flour and salt to the mixture, stirring until the dough comes together.
On a lightly floured surface, roll out the dough to about 1/4 inch thickness.
Cut the dough into desired shapes using cookie cutters and place them on a baking sheet lined with parchment paper.
Bake in the preheated oven for 15-20 minutes, or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
