Steps
- Preheat your oven to 160ºC (320ºF) and line a 12-cup cupcake tin with paper liners.
- In a large bowl, whisk together granulated sugar, Dutch processed cocoa powder, all-purpose flour, instant espresso powder, baking powder, baking soda, and salt until well combined.
- In a separate bowl, combine sour cream, vegetable oil, large eggs, and vanilla extract. Slowly add boiling water while whisking gently.
- Gently fold the wet ingredients into the dry mixture until no lumps remain.
- Divide the batter evenly among the lined cupcake wells. Bake in the preheated oven for 20-23 minutes.
- While the cupcakes cool, crush the Oreo cookies into fine crumbs. Cream the unsalted butter, then gradually add powdered sugar.
- Once cupcakes are completely cooled, generously frost each cupcake with the Oreo buttercream.

Notes
Ensure butter and eggs are at room temperature to enhance texture. For best results, cool completely before frosting.
