Ingredients
  

Chocolate Cupcakes
  • 1 cup all-purpose flour 130g
  • 1 cup granulated sugar 207g
  • 6 tbsp unsweetened cocoa powder 43g
  • 1 tsp baking soda
  • ½ tsp salt
  • 1 large egg
  • ½ cup milk 120ml
  • ½ cup vegetable oil 120ml
  • ¾ tsp vanilla extract
  • ½ cup hot water 120ml
Oreo Buttercream
  • 1 cup unsalted butter 224g, room temperature
  • 3½ cups powdered sugar 403g
  • 1 tsp vanilla extract
  • 4 –5 tbsp heavy cream 60–75ml
  • 1 cup Oreo crumbs about 11–12 Oreos
  • 12 –14 whole Oreos for decoration

Method
 

  1. Preheat oven to 300°F (150°C) and line a cupcake tray with liners.
  2. Mix flour, sugar, cocoa powder, baking soda, and salt in a bowl.
  3. In another bowl, whisk egg, milk, oil, and vanilla.
  4. Combine wet and dry ingredients until smooth.
  5. Add hot water and mix (batter will be thin).
  6. Fill liners halfway and bake for 18–23 minutes.
  7. Cool cupcakes completely.
  8. Beat butter, then add powdered sugar, vanilla, cream, and Oreo crumbs to make buttercream.
  9. Pipe frosting on cooled cupcakes and top with Oreos.

Notes

For the best Oreo cupcakes, make sure not to overmix the batter, as this can make them dense instead of light and fluffy. The hot water step is very important because it enhances the cocoa flavor and gives the cupcakes a soft, moist texture.
Always let the cupcakes cool completely before adding the Oreo buttercream, otherwise the frosting can melt and lose its shape. For a stronger cookies-and-cream taste, use finely crushed Oreo crumbs in the buttercream and add whole Oreos on top just before serving.
These cupcakes taste best fresh on the same day, but they still stay soft and delicious for a few days when stored properly.
