Unwrap and freeze 12 of the Easter Creme Eggs.
Unwrap the other 12 and set aside.
Cupcake – Mix ingredients for cupcakes and fill cupcake wrappers just under 2/3 full. Bake as per instructions, but at the halfway point, pull the cupcakes out of the oven and place a frozen egg on each one, pushing down gently. The egg doesn’t need to be covered at this point, as the cupcake will continue to rise and bake around it. Place cupcakes back in the oven until finished baking. Remove, cool in pan for 5 minutes and then place on a rack to cool. (Make sure they are completely cool before decorating)
Marshmallow Frosting – Whip butter with mixer until soft. Add marshmallow creme and vanilla. Whip for about 2 minutes. Add confectioners’ sugar and mix on medium speed for about 2 minutes or until all sugar is incorporated. Cover and set aside.
Nanaimo Frosting – Whip butter until soft. Meanwhile, mix custard powder with milk. Add to butter. Whip until blended. I find it never completely mixes together (or maybe I’m just impatient) but that’s okay. Add confectioners’ sugar and mix on medium speed for about 2 minutes. Cover and set aside.
To Decorate – Using a piping bag fitted with a #809 tip(or other round tip), pipe marshmallow frosting on cooled cupcakes. Then using the same tip, pipe a smaller circle of Nanaimo frosting in the centre of the cupcake. Place an unwrapped Easter Creme Egg on top.
Keep the cupcakes cool until the frostings set. (I placed mine in the fridge for about 20 minutes)
