Preheat the oven to 350 degrees Fahrenheit.
In a medium sized mixing bowl, add in the flour, baking powder, and powdered freeze-dried strawberries. Stir the ingredients to combine them.
In the stand mixer, cream the salted butter and sugar together until all of the butter lumps are gone.
Add in the egg and vanilla extract and mix until just combined.
Slowly add the flour, baking powder, and strawberry mixture into the wet ingredients until the dough forms a ball. The dough will seem dry at first but it will come together as you continue to mix.
Roll the dough onto a floured surface and use a strawberry cookie cutter to cut out the cookies.
Place six cut out cookies onto a cookie sheet lined with a silicone mat. I like to then place these cookie sheet into the freezer for about five minutes to prevent spread. You can skip this step if you aren't concerned with spread.
Bake for 7-10 minutes or until the center of the cookies do not appear wet. Do not overbake them, as they will not be as soft on the bottom of the cookie.
Allow the cookies to cool for 5 minutes on the baking sheet before transferring them to a piece of parchment paper. Repeat the cookie baking process for all remaining cookies.
