- Preheat oven to 350 degrees F. Add liners to a cupcake tin. Roughly chop the oreos.
- Sift the flour, sugar, salt, baking soda and baking powder together in a large bowl then set aside.
- In a bowl, mix the egg whites, sour cream, milk, and vanilla extract.
- Cream the butter in a large bowl with an electric hand mixer. Beat the dry ingredients into the butter until well incorporated, scrape the bowl at least once. You'll end up with a crumbly mixture.
- Add the wet mixture to the butter/flour mixture and mix on low until just combined. Fold in the chopped Oreos and mix until distributed.
- Divide the mixture evenly into cupcake papers using an ice cream scooper. Bake for about 15-20 minutes or until slightly golden at the edge and springy in the middle.
- Beat the butter until light and fluffy. Add the powdered sugar, vanilla, and heavy cream and mix.
- Crush the Oreos, add to the buttercream and mix until combined.
- Transfer buttercream to a piping bag fitted with a tip of your choice, and pipe buttercream dollops on top.
