Vanilla muffins

Mwahaha! We made vanilla muffins this weekend! おいしかった！
I really believe these are the best muffins I've ever tasted! And here is the recipe!

Vanilla muffins:
250 g butter
4 dl sugar
4 eggs
2 dl milk
6 dl flour
3 teaspoons bakingpowder
1 teaspoon vanilla essence

Vanilla buttercream:

250 g butter
2 teaspoons vanilla essence
2 dl milk
16 dl powdered sugar

Begin by mixing the butter in a bowl so it gets soft. Add the sugar at mix it until it forms a white, creamy texture.
Add the eggs - one at a time - and mix well between each added egg.
Mix in the vanilla essence.
Sift the flour and baking powder, and add it and the milk in the buttermixture a little at a time.
Only mix until the dough is smooth (dont overmix!)

Fill muffin forms about 3/4 full,  and cook them in the middle of the oven. 175*C, 20-25 minutes.

Make the vanilla cream by mixing all the ingredients together, but only add 1/4 of the powdered sugar at first. When the mixture is smooth, add powdered sugar until it forms a nice thickness. If you put the mixture in the refrigerator it will thicken - so don't worry if the mixture seems a bit thin at first. If it's still to thin after keeping it in the fridge, simply add more powdered sugar before decorating the muffins.

If you want other colors,  add a few drops of food coloring (~u~)/

I made 6 big muffins by making １/4 of this recipe. So i guess this is enough for 30 muffins.
