If you’re looking for a show-stopping dessert that blends creamy decadence with rich seasonal flavor, this Sweet Potato Rum Tres Leches delivers in every bite. The tender sponge is enriched with mashed sweet potatoes, soaked in a boozy trio of milks, and topped with whipped cream and cinnamon for a melt-in-your-mouth finish.

Why I Love This Recipe
I’ve always loved tres leches cake for its soft, custard-like texture, but when I started experimenting with adding sweet potato and dark rum, it turned into something magical. The sweet potato adds an earthy richness, while the rum infuses the milk soak with warmth and complexity.
Top it all off with whipped cream and a dusting of cinnamon, and you’ve got an unforgettable dessert that feels nostalgic and indulgent all at once.
Ingredients
For the Cake:
- 1 cup mashed sweet potatoes (about 1 medium sweet potato)

- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt

For the Milk Soak:

For Topping:

Ingredient Swaps & Tips
- Rum: Try spiced rum or bourbon for a twist.
- Sweet Potato: Use canned purée to save time.
- Whipped Cream: Homemade is best, but store-bought works in a pinch.
- Want it alcohol-free? Just replace the rum with extra evaporated milk or a splash of vanilla.
Step-by-Step Instructions
Step 1: Bake the Cake

- Pour the batter into the pan and smooth the top.
- Bake for 25–30 minutes, or until a toothpick comes out clean.
Step 2: Soak with Milk Mixture
- In a bowl, stir together condensed milk, evaporated milk, and rum.
- Let the cake cool for 10 minutes. Then poke holes all over the top with a fork.
- Slowly pour the milk mixture over the warm cake, letting it soak in evenly.
- Cool completely, then refrigerate for at least 2 hours or overnight.
Step 3: Top and Serve
- Before serving, spread whipped cream over the chilled cake.
- Garnish with a sprinkle of cinnamon.
- Slice, serve, and enjoy the magic.
