Preheat the oven to 350°F. Line two baking sheets with parchment paper and set aside.
In a large bowl, whisk together the dry ingredients: flour, baking soda, protein powder, salt, and cornstarch.
In the bowl of a stand mixer with a paddle attachment, beat the butter for about 2 minutes, until creamy.
Add both sugars and beat with the butter for 1 more minute, until creamy.
Add the egg, egg yolk, yogurt, and vanilla, and beat to combine.
Gradually add in the dry ingredients to the wet ingredients, just until incorporated.
Gently fold in the chocolate chips, white chocolate chips, and chopped Oreo cookies.
Scoop out round dough balls and place on the prepared lined baking sheets about 2-inches apart.
Bake at 350°F for 11-13 minutes..
Notes
Makes approximately 28-36 cookies.
The Greek yogurt you use will affect the texture and flavor of these cookies. It's best to choose one that has a creamier texture. You can use a non-dairy Greek yogurt, but know that it will likely give you a soft yet cakier texture than regular dairy yogurt.
