My grandmother used to send me this as a care package in college. It never lasted more than a minute! A favorite of all my friends. ETA--i recently made this with low fat sour cream. It really lost something. I recommend using full fat.
- Preheat oven to 350°F.
- Cream butter and sugar.
- Beat eggs very lightly and add.
- Dissolve baking soda in sour cream. Add to mixture and beat well.
- Add mashed bananas, flour, salt, and vanilla. Mix well.
- Mix in chocolate chips.
- Bake in a well greased 8"x8" pan for 30-35 minutes or until a toothpick inserted in the center of the cake comes out clean.
