Melt the white chocolate carefully in a vessel in the microwave or water bath, stirring every 15 seconds with a silicone spatula.
Let the melted chocolate cool down until it is no longer warm but still runny.
In a bowl, stir the butter and cream cheese until smooth. Stir in the cooled and liquid white chocolate until a homogeneous mass is formed. Then stir in the vanilla extract. Add the bitter almond aroma, start with a drop, test the taste and possibly stir in the rest.
If the frosting is too soft, just cool it down a little in the refrigerator.
The Frosty Creme can be used with a piping bag and palette to decorate cupcakes, cakes and tarts or as a filling.
