In a medium bowl, whisk together the flour, baking powder, and salt.

Step 2

In the bowl of a stand mixer fitted with a paddle attachment, cream the butter and cream cheese together on medium speed until fluffy. Add the sugar on medium-high speed until pale and airy. Mix in the egg and vanilla until combined. Using a rubber spatula, scrape the bottom of the sides and bottom of the bowl.

Step 3

Mix in the dry ingredients on low until just combined. Chill at least 1 hour.

Preheat the oven to 375F. Line a baking sheet with parchment paper or a silicone baking mat.

Using a medium cookie scoop (2 Tablespoons), place the dough onto the baking sheet. Bake 10 minutes, or until the edges just starting to turn golden.

Step 6

Transfer to a wire rack to cool completely. Dust with powdered sugar before serving.
