I am what I am, but there’s no yam in these cupcakes. They’re made with delicious sweet potato! When added to a rich pound cake batter, sweet potato and spices make for a comforting cake, especially during cold-weather days. The cupcakes get even better, however, once you take a bite and realize that they have a sweet flavor surprise: a spoonful of Mighty Maple peanut butter inside of the cake, and a kiss of peanut butter in the frosting. Make this for your Labor Day festivities to mark both summer’s end (sigh) and the start of beautiful autumn days!

Prep time: 1 hour and 30 minutes
Cook Time: 30 minutes
Total time: 2H minutes
Yield: 24 cupcakes

Sweet Potato Cupcakes with Maple Peanut Butter Frosting and Filling



For the cake
3 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
3 teaspoons ground cinnamon
1 teaspoon ground nutmeg
1 cup unsalted butter, softened
1 cup granulated sugar
1 cup light brown sugar, packed
4 large eggs
2 cups canned sweet potato pie filling
1/3 cup milk
1 cup Mighty Maple peanut butter

For the frosting
2 sticks (1 cup) butter, softened
4 cups confectioners’ sugar
1 tablespoon Mighty Maple peanut butter
1 teaspoon vanilla


1. Heat oven to 350°F. Line two cupcake pans with liners (24 cupcakes).

2. In a medium bowl, combine the flour, baking powder, soda, salt, and spices; set aside.

3. Cream the butter with sugars until light and fluffy, 3 to 5 minutes. Beat in eggs, one at a time, scraping down the sides of the bowl with a rubber spatula with each addition and mixing well. Beat in the vanilla and sweet potato until blended.

Cream the butter with sugars until light and fluffy, 3 to 5 minutes.

4. Stir the dry ingredients into the batter in 2-3 increments, alternating with the milk, until blended.

5. Spoon the batter into prepared cupcake tins. These cupcakes will not raise a whole lot, so you can fill them almost to the top.

6. Bake for 30-40 minutes, or until a cake tester or toothpick inserted in the center comes out clean.

7. Cool in the pan until they have reached room temperature.

8. Once cool, use an apple corer or use a knife to cut a small hole in the center of each cupcake, leaving ½ inch cake at the bottom of the cup (this hole will be where you put the filling). Reserve the “cored” pieces of cake, but set to the side.


9. Spoon about 2 teaspoons of Mighty Maple peanut butter into each cupcake. Then, re-insert the removed piece of cake. You should be able to just “smoosh” it right on top of the peanut butter.

PB filling


10. Time to make the frosting. In a stand mixer fitted with the paddle attachment, cream the butter and Mighty Maple peanut butter for 3 to 5 minutes, until smooth. Stir in the vanilla. Add the confectioners’ sugar, cup by cup, until your desired spreading consistency has been reached. Scrape down the sides of the bowl as needed with a rubber spatula. If the frosting becomes too stiff, stir in a small quantity of milk to thin. Frost the tops of the cupcakes, and garnish with cinnamon (if desired).
