These Twix Stuffed Cupcakes feature creamy milk chocolate frosting, caramel drizzle, shortbread cookie crumble and even a piece of Twix candy inside!
While the cupcakes are baking, make the frosting. Beat softened butter on medium speed with an electric or stand mixer for about 3 minutes or until smooth and creamy. Add powdered sugar, cocoa powder, salt, vanilla extract, and milk with the mixer running. Increase to high speed and beat for 3 minutes. Add more powdered sugar if frosting is too thin or more milk if mixture is too thick.
