Banana Bread Muffins

Upon special request, today I am making Banana Bread Muffins:

I got the recipe from my friend's grandma at a wake no less:

.5c shortening

1c sugar

2 eggs (when I double the recipe, I sub out 1 egg for a small scoop of miracle whip)

3 very ripe bananas

3 tbsp buttermilk

1 tsp baking soda

1 tsp salt

2c flour

.5c walnuts

bake at 325 degrees for 25 minutes and then check for done-ness and add 5 minute increments accordingly.
