Ingredients
For the cake:
1 cup all-purpose flour
1 tsp baking powder
1/4 tsp salt
1/2 tsp ground cinnamon
4 large eggs
3/4 cup granulated sugar
1 tsp vanilla extract
1 cup mashed cooked sweet potato (smooth and cooled)
For the milk mixture:
1 can (14 oz) sweetened condensed milk
1 can (12 oz) evaporated milk
1/2 cup whole milk or heavy cream
2–3 tbsp dark or spiced rum
1 tsp vanilla extract
1/4 tsp ground nutmeg (optional)
For the topping:
1 1/2 cups whipping cream
1/4 cup powdered sugar
1 tsp vanilla extract
Optional garnish: ground cinnamon or toasted coconut
Instructions
Preheat oven to 350°F (175°C) and grease a 9×13-inch baking dish.
In a bowl, whisk together flour, baking powder, salt, and cinnamon.
In another bowl, beat eggs and sugar until thick and pale. Add vanilla and mashed sweet potato, mixing until smooth.
Fold dry ingredients into the wet mixture until just combined. Pour batter into the prepared pan and smooth the top.
Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean.
While the cake cools slightly, whisk together sweetened condensed milk, evaporated milk, whole milk, rum, vanilla, and nutmeg.
Poke holes all over the warm cake with a skewer or fork. Slowly pour the milk mixture evenly over the cake.
Refrigerate for at least 4 hours or overnight.
Before serving, whip cream with powdered sugar and vanilla until soft peaks form. Spread over the chilled cake and garnish with cinnamon or toasted coconut if desired.
Notes
Replace rum with bourbon or orange zest for different flavor profiles.
Use coconut milk for richness and top with shredded coconut.
Pecan or walnut garnish adds crunch.
Use canned sweet potato puree (unsweetened) as a shortcut.
Freeze the cake base (not soaked) and soak when ready to serve.
