Apple pie featuring oats

Here's the recipe for a heavenly oat-driven apple pie. Yes, Finns use them even in apple pie. Comes out really good! I recommend it if you still haven't tried!

Ingredients (8 portions):
100 g butter
1 egg
1 ½ dl oats
½ dl sugar
1 ½dl wheat flour
1 teaspoon baking powder

2-3 apples

On top:
50 g butter
½ dl sugar
1 teaspoon vanilla sugar
1 ½ dl oats

Preparation:
Mix the sot butter, egg, sugar, oats, flour and baking powder together. Apply butter on the surface of your baking mould. Press the dough onto the bottom of the mould and use extra flour to help. Peel and slice the apples and settle them on the dough.
For the topping: Melt the butter and mix into it the sugar and the oats. Dust the mix equally on the whole surface of the pie.
Bake the pie in 200 c for 25 minutes.
Excellent served with vanilla sauce or vanilla ice cream!
