Coarsely chop the chocolate coating, melt it on a warm water bath and let it cool down. In the meantime, stir softened butter, warm coconut oil and icing sugar for about 6 minutes until creamy. In the last minute add espresso powder and stir. Now add the cooled liquid chocolate coating bit by bit while stirring.
Put the butter cappuccino cream into a piping bag with a medium-sized punched spout and squirt into the cups. Chill for 1-2 hours until the cream is firm. Dust with cocoa. Keeps cool and dry for about 14 days
