For the Cupcakes:

  • 2 cups all-purpose flour 240g
  • 1 cup sugar 200g
  • 1/4 teaspoon baking soda 1g,
  • 1 1/2 teaspoons baking powder 5g
  • 1/2 tsp salt
  • 3/4 cup unsalted butter 170g, room temperature
  • 3 egg whites
  • 1 teaspoon vanilla extract 5mL
  • 1/2 cup sour cream 120g
  • 1/2 cup whole milk 118mL
  • 1 cup chopped oreos

For the Buttercream:

  • 1 1/2 cup unsalted butter 342g, room temperature
  • 4 cups confectioners' sugar 440g
  • 1/4 cup cream 60mL, added as needed
  • crushed oreos 120g
  • 1 tsp vanilla extract 5mL, optional


For the Cupcakes:

  • Preheat oven to 350 degrees F. Add papers to a cupcake baking sheet. Roughly chop enough Oreos to end up with about a cup.
  • Sift the flour, sugar, salt, baking soda and baking powder together in a large bowl then set aside.
  • In a medium bowl mix the egg whites, sour cream, milk and vanilla extract.
  • Cream the butter in a stand mixer fitted with a paddle attachment, or a large bowl if using 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.

For the Buttercream

  • Beat the butter until light and fluffy. Add the confectioners' sugar, vanilla, and 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, I used and 869 and 1a tip for the cupcakes you see in the post.

For the Assembly

  • Pipe buttercream dollops on top. You can sprinkle with crushed cookie dust and or top with a half Oreo if desired.
