I found this recipe on All Recipes, and noodled around with it a bit. I'm a vegan, so I use soy in place of regular shortening. It makes a heavy loaf, but keeps very well and as I said before just a couple of slices can be very filling. (It's also a super way to use up ageing bananas!)
1/2 cup shortening (I use soy margarine)
1 cup white sugar (brown sugar can also be used)
1 1/2 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon salt
3 ripe bananas
1 teaspoon vanilla extract
1-2 teaspoons your choice spices: cinammon, nutmeg, allspice (I like to mix them up)
Nuts may be added if you like, but I've never made this loaf with them.
Preheat oven to 325 degrees F (165 degrees C). Lightly grease an 8x4 inch loaf pan.
In a large bowl, cream the shortening and sugar. Sift in the flour, baking soda and salt. Blend in the mashed bananas. Pour batter into prepared pan.
Bake in preheated oven for 60 minutes, or until a knife inserted into center of loaf comes out clean.
