Jonathan's Sour Cream Banana Cake

We had to put this one online, the recipe has been used so often that the printouts keep getting covered in drops of batter!

Ingredients:

Original list   DK translation
1/4 cup butter   50g smør
1 1/3 cups sugar   300g sukker
2 eggs   2 æg
1 tsp vanilla   1 tsk vanilje
2 cups unbleached flour   220g hvedemel
1 tsp baking powder   1 tsk bagepulve
1 tsp baking soda   1 tsk natron
3/4 tsp salt   3/4 tsk salt
1 cup sour cream   230 ml creme fraiche
2 medium-ripe bananas (mashed)      

Preheat oven to 180'C (350'F). Cream and beat together the butter, sugar, eggs and vanilla.  In a separate bowl, sift together the flour, baking powder, baking soda and salt.  Add the dry ingredients to the creamed mixture alternately with the sour cream.  Add the mashed bananas and stir briefly.

Turn into a buttered baking pan, 13 x 9 x 2 inches and bake for 35 to 40 minutes.  Test with a toothpick inserted in the centre; when done the toothpick should feel dry to the touch.
