Finely chop the fresh strawberries, pat them completely dry with paper towels, and store them in the fridge until ready to use.
In a medium bowl, whisk together the melted butter and sugar until smooth. Add the egg yolk, vanilla extract, and food coloring, and mix until well combined.
In a separate bowl, combine the flour, baking soda, salt, and freeze-dried strawberry powder. (To make the powder, blend freeze-dried strawberries until fine.)
radually add the dry ingredients to the wet ingredients, mixing until just combined.
Gently fold in the crushed freeze-dried strawberries, fresh strawberries, and white chocolate chips.
Preheat the oven to 350°F.
Scoop the dough onto a lined baking sheet. Gently press the cookie dough and add more chocolate chips on top. Bake for 12-15 minutes, or until the edges are set.
Let the cookies cool on the pan for a few minutes before transferring to a wire rack.
