In a bowl of a standing mixer fitted with paddle attachment, combine the powdered sugar and butter and beat on low speed for about 1 minute. Add vanilla and malt powder, and beat on low until well combined. Add the melted chocolate and beat on medium speed until smooth (about 2 minutes). Add whipping cream and beat on med-high speed for another minute. Best used right away.
*The malted chocolate frosting isn’t my favorite, It isn’t bad though. I’m a lover of freshly made Swiss meringue or French butter cream, nothing compares to those two!
