Preheat your oven to 350F. Line a baking sheet with parchment paper.

In a medium bowl, whisk together your dry ingredients and put aside.

In a large mixer bowl, beat butter and sugar on medium high, until light and fluffy. About 4-5 minutes. Turning the mixer on low speed and add the vanilla, egg, orange zest, and orange juice. Mix until combined and then turn the speed up to medium high for a minute. Scrape down the sides of the bowl and change the speed to low.

Slowly add in your dry mixture until just combined.

Place the powdered sugar into a small bowl and measure a heaping teaspoon of the cookie dough. Roll it into a ball and then roll gently in the powdered sugar. Place the cookie ball onto your baking sheet. Repeat with the remaining dough, leaving enough room for the cookies to spread a little bit.

Bake for 10-12 minutes, or until the bottoms barely begin to brown. The cookies should look dry and cracked on the surface.

Remove the cookies from the oven and let cool on the baking sheet for a few minutes and then transfer to a cooling rack.
