Preheat oven to 350F (175C) and line a 12 count muffin tin with paper liners.
In a large bowl, combine sugar and oil and stir until well-combined. Add sour cream and vanilla extract, stir well.
In a separate bowl whisk together flour, baking powder, baking soda, and salt.
Gently alternate adding dry ingredients and milk to wet ingredients, stirring until just-combined after each addition (don’t over-mix or cupcakes will be dense and dry).
In a separate clean, dry bowl, use an electric mixer to beat your egg whites until you reach stiff peaks (they will be bright white and have increased in volume and when you pull the batter out of the mixture the peaks that form will stay stiff and upright and will not fold over or dissolve into the batter).
Gently fold the egg whites into the batter with a spatula until completely combined.
Carefully stir in broken cookie pieces, then evenly divide cupcake batter into prepared pans, filling each liner ⅔-¾ full. Bake in 350F (175C) oven for 17 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Allow to cool completely in cupcake tin before removing and covering with frosting.
Prepare cream cheese frosting or preferred frosting according to recipe instructions, then stir in pulverized cookie crumbs (if desired, reserve a tablespoon or two to sprinkle on top of the icing). Spread or pipe over cooled cupcakes. Enjoy!
