Strawberry & banana pudding cake

This is the cake I made for International Children's Day (1st of June) and it's actually a Fraisier type of cake, adapted to be baby friendly. I got inspired by a wonderful cake I saw on a Romanian blog called Savori Urbane (recipe here) and I decided to bake something similar (at least in aspect, as I changed the ingredients a bit...).
I wanted to prepare a cake just the right size for our family's dinner so I used a cake tin of 10 cm diameter, with a removable ring. I made some more batter though, so apart from the small cake I also had 3 mini-tarts (baked in silicone molds), that we "tasted" the evening before. They were yummy!

So, here's my take on Fraisier cake, baby friendly version. For larger cake tins, just double or triple the ingredients.

Ingredients:
For the base:
2 eggs
2 Tbsp flour
1 Tbsp coconut oil
1/2 banana, mashed

For the banana & vanilla pudding:
250 ml milk
1/2 vanilla bean
3 egg yolks
1/2 banana, mashed
15g cornstarch
75g butter 80% fat, room temperature

For the filling and topping:
10-15 small strawberries

Method:
Base:
Preheat the oven at 190 degrees C.
Mash the banana, add the egg yolks and oil and mix well. Add the flour and mix some more.
Separately, beat the egg whites until fluffy and add them to the batter. Mix carefully, using a spatula, to keep as much fluffiness as possible.
Pour the batter into tins / molds (I used a cake tin and 3 silicone molds - see some of the cakes in the picture below). Bake for 10-15 minutes, until the surface is golden brown. Remove from the oven and let cool. Cut the cake base into 2 layers.

Pudding:
Heat up the milk with the vanilla bean and the vanilla seeds (be careful to remove it from the heat when it starts boiling).
Meanwhile, mix the egg yolks with the mashed banana until they get foamy. Add the cornstarch and mix well. Pour the hot milk gradually (after you removed and discarded the vanilla bean) and mix well.
Put the batter back on the stove and stir continuously with a silicone spatula. Let it simmer for a few minutes, until it gets thick and remove from the heat. Pour the pudding in a bowl lined with cling film and cover with the cling film's margins and let cool (if left uncovered, it will form a crust).
Whisk the butter (room temperature) until it gets creamy and a bit fluffy and add the cold vanilla pudding on top. Continue mixing until you it gets nice and creamy. If the butter starts separating, just continue to mix. It should be fine in a few minutes.

Wash the strawberries, dry them on a paper towel and cut 4-5 of them in halves.

Cake assembly:
Place half of the cake base on a plate, with the ring from the cake tin around it. Cover with a little pudding and place the halved strawberries on the circle, with the cut part outside. Then, fill all the inside with whole strawberries.

 
Pour more pudding into the tin, to cover all strawberries and press with a spoon, so that the cream gets everywhere between the fruit. Place the other half of the cake base on top, cover it with some more pudding and decorate with strawberries.
Let it cool in the fridge for a few hours before removing the ring.
Enjoy!
