Ingredients
For the Cupcakes:
-
1 ½ cups all-purpose flour
-
1 tsp baking powder
-
½ tsp baking soda
-
½ tsp salt
-
1 tsp ground cinnamon
-
½ tsp ground nutmeg
-
¼ tsp ground ginger
-
¼ tsp ground cloves
-
½ cup (1 stick) unsalted butter, softened
-
¾ cup brown sugar, packed
-
¼ cup granulated sugar
-
2 large eggs
-
1 tsp vanilla extract
-
1 cup mashed cooked sweet potatoes (about 1 medium sweet potato)
-
½ cup buttermilk
For the Honey Butter Frosting:
-
½ cup (1 stick) unsalted butter, softened
-
3 tbsp honey (preferably raw or wildflower)
-
2 cups powdered sugar, sifted
-
1–2 tbsp heavy cream or milk (as needed for consistency)
-
Pinch of salt
Instructions
Preheat your oven to 400°F (204°C). Prick a sweet potato several times with a fork, place it on a baking sheet, and roast for 45–60 minutes until soft. Let it cool, then peel and mash until smooth. Set aside 1 cup for the cupcakes.
Lower the oven temperature to 350°F (175°C). Line a 12-cup muffin pan with paper liners.
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, nutmeg, ginger, and cloves.
In a large bowl, beat the softened butter, brown sugar, and granulated sugar together until light and fluffy—about 3–4 minutes.
Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract and mashed sweet potato until combined.
Add the dry ingredients in three parts, alternating with buttermilk, beginning and ending with dry ingredients. Mix just until combined—don’t overmix.
Divide the batter evenly among the prepared cupcake liners, filling each about ⅔ full. Bake for 18–22 minutes or until a toothpick inserted into the center comes out clean. Allow cupcakes to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
In a large bowl, beat the softened butter and honey together until creamy. Gradually add the powdered sugar, mixing until smooth. Add heavy cream one tablespoon at a time to reach your desired frosting consistency. Beat for 2–3 minutes until light and fluffy.
Once the cupcakes are fully cooled, frost generously with the honey butter frosting. You can pipe it on for a fancy look or spread it with a spatula for a rustic touch.
Notes
Make sure your sweet potato mash is completely smooth—lumps can create uneven texture in the cupcakes. If necessary, puree the sweet potato in a food processor for a silky finish. Also, use room temperature ingredients for the best batter consistency.
