With the help of the push up pop moulds, cut the cake sponge into circles. This way you get the perfect size that will fit inside.

Fill your frosting into a piping bag and cut the tip.

Now place one circle in the bottom of the mould. Then fill the frosting in a thin layer.

Then place the cake circle again and then pipe the frosting.

Repeat this until the mould is full.

Put some decoratives on top.

I used red velvet cake sheets and plain whipped cream frosting. You can use any cake and frosting.
