Ingredients

• 1.5 cups Sweet potatoes (mashed)
• 2.5 cups All-purpose flour
• 2 teaspoons Baking powder
• 0.5 teaspoons Baking soda
• 1.5 teaspoons Ground cinnamon
• 0.5 teaspoons Ground nutmeg
• 0.5 teaspoons Salt
• 1 cup Unsalted butter (softened)
• 1.25 cups Granulated sugar
• 0.5 cups Brown sugar (packed)
• 4 Large eggs
• 0.5 cups Dark rum
• 2 teaspoons Vanilla extract
• 0.5 cups Milk
• 3 cups Powdered sugar
• 0.5 cups Butter (softened, for frosting)
• 3 tablespoons Dark rum (for frosting)
• 2 tablespoons Heavy cream (for frosting)

Directions

Step 1

Preheat your oven to 350°F (175°C) and grease and flour a 10-inch bundt pan.

Step 2

In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, cinnamon, nutmeg, and salt. Set aside.

Step 3

In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar together until light and fluffy, about 3–4 minutes.

Step 4

Add the eggs, one at a time, mixing well after each addition.

Step 5

Mix in the mashed sweet potatoes, dark rum, and vanilla extract until smooth and well-combined.

Step 6

Gradually add the dry ingredients to the wet ingredients in three parts, alternating with the milk, starting and ending with the dry ingredients. Mix until just combined, being careful not to overmix.

Step 7

Pour the batter evenly into the prepared bundt pan and smooth the top with a spatula.

Step 8

Bake in the preheated oven for 45–50 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool in the pan for 15 minutes before transferring to a wire rack to cool completely.

Step 9

For the frosting, beat the softened butter, powdered sugar, dark rum, and heavy cream together in a medium bowl until smooth and creamy. Add more heavy cream if needed to reach your desired consistency.

Step 10

Once the cake is fully cooled, spread the butter rum frosting evenly over the top of the cake.

Step 11

Slice and serve for a taste of the Caribbean with every bite!
