It’s funny, I haven’t even posted the recipe I bought the buttermilk for originally, just the ones I made trying to use it up. This bread is good for people who like sweet things. It’s dense, very moist, and heavy on autumn spice flavors. I think it could probably use a bit more salt. And although I used buttermilk, sour cream might be better. Or a bit of orange zest? I just think it needs some more ‘zazz. It’s nice with a cup of tea for breakfast or in the afternoon.

cooking spray or baker’s joy
1–2 sweet potatoes/garnet yams, between 1–1.25 lbs. (you want 1 1/2 cups of mashed sweet potato once they’re steamed)
1 1/4 cups white sugar
1/4 cup brown sugar, packed
2 eggs
1/2 cup vegetable oil
1/4 cup buttermilk (or sour cream)
1 tsp vanilla extract
1 3/4 cups AP flour
2 tsp baking soda
1 Tbsp cinnamon (all spices ground)
1 tsp ginger
1 tsp nutmeg
1/2 tsp allspice
1/2 tsp cloves
1/2 tsp kosher salt (full tsp might be better)

Heat oven to 350. Prep a 9×5 loaf pan with cooking spray or baker’s joy.

Cut the sweet potatoes into 1-inch chunks and place in a steamer insert. Put an inch of water in a saucepan and bring to a simmer. Place insert in pan and steam sweet potatoes for approximately 15 minutes or until quite soft. Remove to a bowl and mash to a pulp. (This can be done by hand, with a hand mixer, or in a stand mixer.)

Mix in the sugars. Add eggs, oil, buttermilk, vanilla and beat until combined. In another bowl, sift together the flour, baking soda, cinnamon, ginger, nutmeg, allspice, cloves, and salt. Add the dry ingredients to the wet in stages and mix until the flour mixture has been incorporated thoroughly (however, try not to overbeat—fold in if you’re doing it by hand).

Empty batter into prepared loaf pan and smooth the top with a spatula. Bake at 350 for 60–75 minutes, checking for doneness with toothpicks. Cool in pan for 15–30 minutes, then turn out onto a rack.
