Indulge in moist chocolate cupcakes with a hidden Oreo surprise, topped with a fluffy, rich cookies and cream frosting.
Always use room temperature eggs and butter for the frosting for the best texture.
Ensure both the chocolate mixture and the flour-milk mixture are thoroughly chilled before proceeding.
Measure flour by spooning it into the measuring cup and leveling it off with a knife.
Do not overmix the cupcake batter to keep them tender.
For the best crushed Oreos, use a rolling pin to create a mix of fine crumbs and small chunks.
