These cupcakes are super simple to make and equally fun to serve! The sponge is moist and crumbly, but the cookie part gives the missing crunch. The overall flavor is specific and rich, due to buttermilk and sour cream in the batter.
In a large mixing bowl, combine wet ingredients: buttermilk, olive oil, sour cream, and eggs.
Sift in dry ingredients: flour, instant vanilla pudding powder, baking powder, and sugar.
Dissolve cocoa powder in boiling water. Add a drizzle of water, enough for it to become a paste, nothing more.
Use only a whisk to fuse everything, but don’t mix too much, the goal is no flour lumps solely. The batter consistency will be similar to the pancake batter.
Baking
Take a muffin tin and cover it with cupcake liners or baking paper.
Take Oreo cookies and part them carefully, so all the filling is left on one side. Place each half on the bottom of the cupcake liners, with the filling side up.
Use a scoop to pour the batter over them, filling 2/3 of the tin. Shake it slightly, so the batter can slide under the cookie.
Bake them for about 20 minutes at 350 °F (180 °C), but check with a toothpick.
Arrange them on a rack, so they don’t over-dry from hot tin. Let them chill for about half an hour, so the frosting doesn’t melt.
Making the Frosting
In a bowl, meld butter, cream cheese, and vanilla extract.
Mix it well until creamy, then add powdered sugar. Mix again to get smooth, silky, but firm frosting that is easy to pipe.
Crush some Oreo leftovers and sprinkle on top.
Notes
