I know, there's a million ways to make banana cake. I like this one. It's good plain (especially if you add the chocolate chips) or frosted (I tried it with the Chocolate Cream Cheese Frosting (recipe at this site) and it was really really really good).
2 ½ C flour (I usually do half whole wheat)
1 T baking soda
pinch of salt
½ C butter
1 C sugar
¾ C brown sugar
2 eggs
4 ripe bananas, mashed
2/3 C buttermilk*
½ C chocolate chips or chopped walnuts(optional)
Preheat oven to 350° F. Grease and flour two 8-inch round pans, or 1 8- or 9-inch square pan, or line 24 muffin cups with paper liners.
In a small bowl whisk together flour, soda and salt; set aside. In a large bowl cream the butter and sugars until light and fluffy. Beat in eggs one at a time. Mix in the bananas. Add flour mixture alternately with the buttermilk to the creamed mixture. Stir in chips or walnuts if desired.
Pour batter into the prepared pans. Bake until done -- the muffin pan will probably take 20-25 minutes, the round pans will probably take 30-40 minutes, the square pan will probably take 35-45 minutes. You'll just have to check early, and check often.
* If you don't have buttermilk on hand, you can substitute 2/3 C milk that has been combined with 2 tsp white vinegar and allowed to sit for 10 minutes, or 2 parts plain yogurt and 1 part milk, or sour cream. (Ref: Cook's Thesaurus).
