Preheat the oven to 375°F. Line two baking sheets with parchment paper.
In the bowl of a stand mixer fitted with the paddle attachment, add the butter, light brown sugar, and cane sugar. Mix on low until combined and there are no butter chunks.
Add the milk, all purpose flour, cocoa powder, baking powder, and salt. Mix on low until combined.
Add the freeze dried strawberries, but reserve a small amount if you want to add them on top. Mix until combined.
Using your hands, roll the dough into 12 balls and place on the prepared baking sheets. Flatten them slightly so they are about 2-inches in diameter.
Bake for 15 to 17 minutes or until the tops and edges are dry.
As soon as the cookies come out of the oven, you can add the extra freeze dried strawberries on top. I also sprinkle them with a little dusting of cane sugar.
Store in an airtight container for up to 7 days.
