Titus and Dante wanted to make a cake. I had them make this classic quatre-quarts plus a little vanilla, but you can add whatever you'd like. For vanilla though, use vanilla extract or the scraped out seeds from a fresh vanilla pod if you have it - that's the best.
This is, literally, easy as cake. Easy enough for kids, for sure. And delicious! Leftovers? Well, this keeps well-wrapped in the fridge for several days. Or you can toast a slice or two, top with with berries and whipped cream perhaps?
Titus' Vanilla Cake
1 tsp baking powder
200 g butter, melted
Beat eggs and sugar until pale and fluffy. Stir in flour and baking powder, and the melted butter and the vanilla. Pour into a well-lined cake pan and bake in a 200�C oven, for 30-35 minutes. Check to make sure it's baked through.
