Cream decorated cake

Overview

I made this for my son’s birthday. It’s my first time making a decorated cake

The cake is a finished product, I’m not very good at making it yet and I’m afraid of failure
The custard contains powdered sugar and is beaten with an electric whisk
This is my first time making this, so I don’t know how well I beat it. I turned the pot upside down and the cream didn’t flow. In fact, I should beat it again and it will feel better
Slice the cake from the middle
Sprinkle some fruit pieces and spread a layer of cream
Cover the cake, spread butter evenly on the cake and start decorating. There is no filming during the decorating process
Okay, I took the photo with my mobile phone and it’s okay to watch
Something was messed up haha, my son is always causing trouble
