You can make your own cake embryo, buy corresponding tools, or go to a special bakery to make it. This is a cake embryo made in advance.

Put the fruit sandwich, first cut the cake in the middle and put a little cream in the middle, so that the fruit in the middle can be fixed by the viscosity of the cream. Add pineapple and coconut, pay attention to the right amount of cream, not too much.

After putting the fruit in the interlayer, you can cover it and smooth the cake with cream. Making a cream cake is the most difficult part. You need to carefully smooth the cream on the surface of the cake. After smoothing, move the cake to the cardboard with a knife and start painting decorations. It's best to tick off the outline with a toothpick first, so as not to make the syrup uncorrectable and eat it all at once.

I can see that it is Doraemon, haha, the nose and tongue are all red jam, surrounded by blue cream.

Finally, you can write it on the side for decoration.

Finally, put a full picture and you're done.
