Yet another version; I’m always trying different ones. This one is a winner.

1 cup Bran Flakes
½ cup shortening
1-1/2 cups sugar
3 eggs
2-1/2 cups flour
2-1/2 teaspoons baking soda
2 cups buttermilk
2 cups All-Bran

Preheat oven to 400 degrees. Pour 1 cup boil water over Bran Flakes. Cool. Cream together shortening and sugar. Beat in eggs. Add flour, baking soda and buttermilk; mix well. Stir in All-Bran. Fill greased muffin tins about 2/3 full (makes about 2-1/2 – 3 dozen). Bake for 20 minutes. Remove from pans to finish cooling.
