Vanilla Oat Cake - cooking recipe

Ingredients

Cake
700 ml flour
300 ml sugar
300 ml milk
1 egg
4 teaspoons vanilla sugar or 4 teaspoons vanilla extract (I prefer the sugar)
100 g melted butter
4 teaspoons baking powder
Topping
200 g melted butter
200 -300 ml oats
200 ml sugar
4 teaspoons cinnamon

Preparation

(1 cup= 2 1/2 dl).
Preheat oven to 400.
Mix all the ingredients for the cake (in no special order) in a mix master for approximately 4 minutes or until well blended and slightly fluffy spread on a greased or lined 9 by 13\" pan.
Mix all the ingredients for the topping and pour over the top.
(the idea is to leave some patches bare and get a marble effect) cook for 20 minutes or until inserting a toothpick in the center comes out clean.
(the cake may look undercooked).
let the cake stand for about 10 minutes.
