Sweet Potato Bread with Buttermilk Lime Frosting

I make a lot of different quick breads, probably a half dozen or more recipes.  This one is quite unique.  It can be served with or without the frosting. . . but include the frosting!

Salted butter for greasing the pan

1 3/4 cups self rising flour

1 1/2 teaspoons ground cinnamon

1/2 teaspoon ground nutmeg

1/2 teaspoon ground ginger

1/2 teaspoon baking powder

1/8 teaspoon ground cloves

1/2 teaspoon salt

1 1/3 cups light brown sugar

1 cup mashed roasted sweet potato

3/4 cup vegetable oil

1 teaspoon vanilla extract

3 large eggs, at room temperature

Frosting

2 1/2 cups sifted powder sugar

2 tablespoons buttermilk

1 tablespoon fresh lime juice

1/2 teaspoon vanilla extract

pinch of salt

lime zest

Preheat oven to 350.  Grease a loaf pan with butter, set aside. 

Combine flour, cinnamon, nutmeg, ginger, baking powder, cloves, and 1/2 teaspoon salt in a large bowl.  Whisk together brown sugar, sweet potato, oil, and 1 teaspoon vanilla in a separate bowl.  Add eggs, one at a time to brown sugar mixture, whisking to combine after each addition.  Slowly add brown sugar mixture to flour mixture, whisking constantly until well combined.

Transfer batter to prepared loaf pan.  Bake on middle rack in preheated oven until a wooden toothpick comes out clean, about one hour.  Remove bread from oven; cool in pan on a wire rack for 15 minutes.

Prepare the icing:  Whisk together powdered sugar, buttermilk, lime juice, 1/2 teaspoon vanilla, and pinch of salt in a medium bowl until smooth.

Remove the bread from pan, and cool on wire rack.  Drizzle bread with frosting while the loaf is still warm.  Top with zest.

Soooo good!
