Pulse the freeze-dried strawberries in a food processor into a fine powder. Set aside 2 tablespoons of the crumbs for topping.
Blend the cottage cheese until completely smooth. In a large bowl, beat the softened butter and sugar for 2 minutes, then beat in the blended cottage cheese, egg yolk and vanilla until creamy.
Add the strawberry powder, flour, protein powder, baking powder, baking soda and salt, and mix until a soft pink dough forms. Fold in the white chocolate chips, cover and chill for 30 minutes.
Preheat the oven to 350°F and line 2 baking sheets with parchment paper. Scoop 1 1/2 tablespoon balls of dough, place them 2 inches apart and flatten slightly.
Bake for 10 to 11 minutes, until set but not browned, which keeps the color bright pink. Cool completely on a wire rack.
Melt the dark chocolate chips with the coconut oil in 30 second bursts, stirring between each, until smooth. Dip half of each cookie into the chocolate, place on parchment and sprinkle with the reserved strawberry crumbs.
Let the chocolate set for 20 minutes at room temperature or 10 minutes in the fridge.
