Preheat oven to 350° F and line two baking sheets with parchment paper.
Grind 1½ cup strawberries in a food processor until they become a fine powder.
In the bowl of a standing mixer with the paddle attachment or a handheld mixer, combine butter and sugar, mixing until light and fluffy. Add in ½ cup of freeze dried strawberry powder (leave remaining 1 cup aside for frosting).
Add in the egg and vanilla extract, and mix until combined and light in colour.
Mix in the flour, salt, baking powder, and baking soda until combined. Do not over-mix!
Use a cookie scoop or a spoon, scoop 1.5 tbsp sized balls onto the baking sheets. Be sure to leave at least 4-5 inches between each ball of dough, as the cookies will spread out.
Bake one tray at a time for 8-11 minutes, until edges look set. The middles will look soft. Let the cookies cool on the baking sheets for 10 minutes, then transfer to a cooling rack to cool completely before frosting.
Make the frosting. In a medium bowl combine butter and 1 cup freeze dried strawberry powder. Add in powdered sugar, salt, and lemon juice. Add milk slowly until frosting reaches your desired consistency. To thicken, add a little more powdered sugar.
Frost the cookies and enjoy!
