I modified this a bit to make it more of a snack or breakfast cake but will include the original instructions in parenthesis so you know how it was intended for a dessert cake.
2 1/2 c flour - i always use whole wheat - white whole wheat worked really well. -none knew
1 c sugar (1 2/3 c)
1 1/4 t baking soda
1 1/4 t baking powder [1t soda + 2t cream of tarter = 1 T baking powder]
1 t salt
2/3 c butter or coconut oil - NEVER USE MARGARINE OR SHORTENING!!
1/3 c butter milk or kefir
3 mashed over ripe bananas or 1 1/4 c
1/3 c buttermilk or kefir- yes another
1/2 c or 2 large unbeaten eggs or 3 medium
Optional 2/3 c copped nuts or chocolate chips
*Preheat oven to 350
1. Mix first 5 ingredients.
2. Add next e and beat vigorously for 2 minutes in mixer
3. Add remander or milk and eggs. Beat for 2 more minutes.
4. Fold in add-ins if you choose
5. Bake for 18-20 minutes using 2 9" rounds, 11x16 or cupcakes/ muffins.
Dessert cake may be frosted with icing (suggested in my book) or chocolate frosting (my idea).
