Uncle Gene's favorite.

You can substitute butter for shortening and slightly scant the buttermilk to make up for the liquid difference.

Ingredients Step
Preheat oven to 350 degrees.
2¼ c. (270 g) cake flour
1 c. sugar
1 t. baking powder
¾ t. baking soda
1 t. salt
1 t. cloves
¾ t. cinnamon
½ t. nutmeg
Sift dry ingredients together in the bowl of a stand mixer.
Grease and flour two 9" round cake tins (1½ inch deep).
¾ c. brown sugar
¾ c. shortening
1 c. buttermilk
Stir into the flour mixture, then beat for 2 minutes.
3 medium eggs Add and beat in for 2 minutes.
Pour into prepared pans. Bake 20-35 minutes, obeying the toothpick test.
Cool slightly and remove from pans.
1½ c. brown sugar
¼ c. cream (ideally clotted cream or cream from the top of non-hydrogenated milk)
2 T. butter
1 T. vanilla
As you remove the cakes from the oven, prepare the frosting: Bring ingredients to a boil and boil for 3 minutes, stirring constantly. Remove from heat, then use a hand blender to beat until creamy, adding a little cream if necessary to make it easier to spread. Spread it onto the cake while the cakes are still warm.
Cut cake while warm.
