In a medium bowl, whisk together the flours, cornstarch, baking soda, and salt and set aside.
In a stand mixer, cream together the butter and both sugars on a low speed until combined. Scrape the bowl down once or twice as needed. Add the corn syrup and beat until combined.
Add the egg and vanilla. Beat until combined. Scrape the bowl down as needed.
Add the dry ingredients to the wet and mix on low until just combined. Add the white chocolate chips, ruby chocolate, and freeze dried strawberries. If desired, reserve some of these mix ins for topping later. Mix on low until combined. It should just take a few seconds.
Use a large cookie scoop to portion the dough and place onto a tray or baking sheet lined with parchment paper. Repeat with the remaining cookie dough.
Place the trays in the freezer for at least one hour. Transfer the frozen cookie dough balls to a freezer bag or airtight container. Freeze for at least 4 hours, but preferably overnight.
When you are ready to bake, preheat the oven to 325°F. Place frozen cookie dough balls on a baking sheet lined with a silicone baking mat or parchment paper. Bake for 21- 22 minutes or until lightly golden brown.
Let them cool on the baking sheet for 5- 10 minutes before transferring them to a cooling rack.
If desired, melt some of the reserved white chocolate and ruby chocolate. Drizzle over the cooled cookies and sprinkle with freeze dried strawberry bits.
