Bakers please helpšŸ™ˆā¤!

My fiances birthday is coming up and he wants me to make him a plain and simple ice cream cake.

He *specifically* wants this cake because of the frosting that was typically put on the cake from his childhood.

Does anyone know what that frosting is?

Whipped cream? Buttercream?

Please help ā¤ā¤šŸ§
