Banana Chocolate Chip Cake - cooking recipe

Ingredients

1/2 cup butter or 1/2 cup margarine, cut in 1/4 chunks
1 1/2 cups sugar
2 eggs
1 teaspoon vanilla
2 large bananas (very ripe)
1 teaspoon baking soda
3/4 cup plain yogurt or 3/4 cup sour cream
1 teaspoon baking powder
2 cups flour
1 cup chocolate chips
3/4 cup chopped pecans (optional)

Preparation

Process butter, sugar, eggs and vanilla for 2 minutes, scraping down bowl once or twice.
While machine is running, drop chunks of bananas through the feed tube. Process until blended ( I mash my bananas before hand).
Meanwhile, dissolve baking soda in yoghurt or sour cream. Let is stand for l to two minutes Yoghurt will nearly double in size, so use a 2 Celsius measuring cup.
Add to batter and process for 3 seconds.
Add flour and baking powder.
Process with 4 quick on/off turns, just until flour mixture disappears.
Add remaining ingredients.
Bake in 2 greased and floured 8 inches pans for 25-30 minutes at 350\u00b0F
(I also use waxed paper on the bottom of the pans - just cut a circle for the bottom - it makes it easier to take the cake out ) or until cake tester come out clean.
Cool for 10 minute
Remove from pan.
