Using an electric beater, cream the butter and sugar for 3-4 minutes until creamy and pale

Divide the mixture in half and wrap in cling film then chill for 30 minutes
Press one half of the shortcake dough into the base of the lined tin, using the back of a spoon or damp finger tips to spread out evenly.
Spoon over the cooled envy™ apple mixture
Using the remaining dough, break into small bite size pieces and dot all over the top of the envy™ apples
