Preheat the oven to 325 degrees F. Line a cookie sheet with parchment paper. Put the cup of powdered sugar in a small bowl and set aside. Place the cup of freeze dried strawberries into a mini food processor, and process until they are ground into a fine powder. Set aside.
Put the vegan buttery spread, vanilla extract, applesauce, salt, and cane sugar in a mixing bowl. Beat on high speed until light and fluffy.
Stop the mixer, and add the gluten free flour blend, salt, and powdered strawberries. Mix on medium speed until the dough comes together.
Roll the dough into one inch balls and place them on the cookie sheet, with about an inch and a half in between them. 12 cookies should fit on the cookie sheet.
Bake at 325 degrees F for 18-21 minutes, until the cookies are golden brown on the bottom. I recommend baking one pan at a time. When I baked these on a lower rack in the oven, the bottom of the cookies browned too quickly.
Let the cookies cool for about 15 minutes before rolling them in the powdered sugar.
While the cookies are still warm, roll them in the powdered sugar. Let the cookies cool fully, then roll in the powdered sugar again to get a nice white coating.
Repeat steps 5-8 with the remaining dough.
