Method
Heat the oven
Ask a grown-up to turn the oven to 180°C and grease a cake tin.
Cream butter & sugar
Mix the butter and sugar together until it looks pale and fluffy. Add the eggs one at a time, then stir in the vanilla.
Add the dry mix
In another bowl, mix the flour, baking powder, and salt. Add this to the butter mixture a little at a time, along with the milk, and stir just until it's all combined — no need to overdo it.
Bake
Pour the batter into the tin and pop it in the oven for 30 to 35 minutes, until a toothpick comes out clean. Let it cool before you touch it, however hard that is to wait for.
Vedhica's note: No frosting. No decoration. Just a cake for two very patient dolls.
