Sweet Potato Cupcakes With Toasted Marshmallow Frosting

Okay, how cool is this for Thanksgiving?  I’m so going to bake these again…  Only big change I noticed is that I wanted to bake fresh sweet potatos for the recipe, and there’s lots of evaporation.  You’ll need two HUGE sweet potatos to have enough.  Canned sweet potato puree works just as well.

Printer-Friendly Version

For the cupcakes:
2 cups all-purpose flour
2 tsp. baking powder
½ tsp. baking soda
¼ tsp. salt
1 tsp. ground cinnamon
16 tbsp. unsalted butter, softened
1½ cups sugar
3 large eggs
17 oz. sweet potato puree
½ tsp. vanilla extract

For the frosting:
8 large egg whites
2 cups sugar
½ tsp. cream of tartar
2 tsp. vanilla extract


Preheat the oven to 350° F.  Line two cupcake pans with paper liners.  In a medium bowl combine the flour, baking powder, baking soda, salt and cinnamon; stir together with a fork and set aside.  In the bowl of an electric mixer fitted with the paddle attachment, cream together the butter and sugar on medium-high speed until light and fluffy, about 2 minutes.  Beat in the eggs one at a time, scraping down the bowl after each addition.  Mix in the sweet potatoes and vanilla extract, beating just until combined.  Reduce the mixer speed to low and add the dry ingredients, mixing just until incorporated.

Divide the batter evenly between the prepared cupcake liners.  Bake for about 18-20 minutes, or until a toothpick inserted in the center comes out clean.  Let cool in the pan for 5-10 minutes, then transfer to a wire rack to cool completely.

To make the frosting, combine the egg whites, sugar and cream of tartar in the top of a double boiler. (Note: I just set my clean, dry mixer bowl over simmering water, to avoid dirtying two bowls.) Heat the mixture, whisking frequently, until it reaches 160° F with an instant-read thermometer. Transfer the mixture to the bowl of an electric mixer fitted with the whisk attachment. Whisk starting at low speed and gradually increasing to medium-high speed until stiff, glossy peaks form. Mix in the vanilla until combined. Frost cooled cupcakes as desired. Brown with a kitchen torch and garnish with a sprinkle of brown sugar, if desired.
