Bourbon Potato Casserole Cupcakes
For the Cupcakes:
- 1 1/2 cups sweet potato puree about 3 small potatoes
- 1 ¾ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- 2 teaspoons cinnamon
- ½ teaspoon kosher salt
- ⅛ teaspoon freshly ground nutmeg
- ½ cup light brown sugar packed
- ½ cup granulated sugar
- ½ cup unsalted butter room temperature
- 2 tablespoons bourbon
- 1 teaspoon lemon zest about 1 small lemon yellow parts only
- 4 eggs
- 1 ½ teaspoons vanilla
- ⅔ cup whole milk
For the Topping:
- ½ cup dark brown sugar packed
- ⅓ cup flour
- 6 tablespoons melted butter
- 1 cup chopped pecans toasted
- 1/8 teaspoon cinnamon
- Pinch kosher salt
For the marshmallow frosting
- 4 egg whites
- 1 cup sugar
- 1/4 teaspoon kosher salt
- 1 teaspoon vanilla extract
- 1/8 teaspoon cinnamon
Cook Sweet Potatoes:
- Preheat oven to 400 degrees. Place potatoes on a baking sheet, pierce each one a few times with a fork, and bake for roughly one hour or until very tender and can easily be pierced with a fork. Mash with a spoon or press through a ricer.
Make the Topping
- Mix all the topping ingredients together in a medium bowl and set aside.
Make the Cupcakes:
- Preheat your oven to 350° and line 18 muffin tins with liners.
- In a medium bowl whisk together flour, baking powder, soda, cinnamon, salt, and nutmeg; set aside.
- In the bowl of a stand mixer fitted with the paddle attachment, cream sugars, butter, bourbon, and lemon zest together with a hand mixer until thickened, 3-4 minutes. Add eggs one at a time, beating well between each addition. Add the vanilla with the last egg.
- Add the sweet potato puree and mix on medium until smooth and creamy, about 30 seconds.
- Alternately add flour and milk, beginning and ending with flour. I add a third of the flour then half of the milk and repeat. Fold the last flour addition in by hand to avoid over mixing.
- Scoop into prepared tins, filling almost to the top of the cup.
- Add the topping to the top of each cupcake, pressing some down inside. Bake in preheated oven 15-20 minutes or until a toothpick inserted near the center comes out with a few clinging crumbs.
- Remove from muffin tins to cool completely on a wire rack.
Make the Marshmallow frosting
- Fill a saucepan with a couple of inches of water and place it over medium heat. Bring the water to a simmer. Find a heatproof bowl that fits snugly on top of the saucepan without touching the water. This will be your double boiler.
- In the heatproof bowl, whisk together the egg whites, sugar, salt, and cinnamon.
- Place the bowl over the simmering water in the saucepan. Ensure that the bottom of the bowl doesn’t touch the water. Whisk constantly for about 4-5 minutes or until the sugar has completely dissolved. You can test this by rubbing a bit of the mixture between your fingertips to check for sugar granules. If it feels smooth, it’s ready.
- Transfer the bowl to a stand mixer or use a hand mixer. Begin whipping the mixture on high speed for about 5-7 minutes or until stiff peaks form and the mixture becomes glossy.
- Once you’ve reached the desired consistency, add the vanilla extract. Mix for an additional 1-2 minutes until well combined.
Assemble the Cupcakes:
- Once cupcakes are cool, frost with a wide piping tip.
- Toast the frosting with a kitchen torch or under a broiler, being careful not to burn the topping.
