Step 1

Combine the bottle of port and 2 1/2 cups rum in a large pot or bowl and add the prunes, currants, raisins and cherries. Soak the fruit for at least 2 days.

Step 2

Preheat the oven to 350˚ F. Butter three 9-inch round cake pans and line the bottoms with wax or parchment paper. Drain the dried fruit and transfer to a blender; blend well.

Step 3

Beat the butter and brown sugar in a large bowl with a mixer on medium-high speed until fluffy, about 5 minutes. Beat in the eggs, one at a time, until fully combined. Mix in the fruit mixture.

Step 4

Add the flour, baking powder, nutmeg, cinnamon, allspice and cloves to the bowl and beat until combined, 1 to 2 minutes. (If using a stand mixer, you may need to beat the wet ingredients, then transfer to a larger bowl and stir in the dry ingredients.) Mix in the vanilla and browning. Divide the batter evenly between the cake pans.

Step 5

Bake the cakes until set and a toothpick inserted into the middle comes out clean, 1 to 1 1/2 hours. Remove the cakes from the oven and pour 3/4 cup each port and rum onto the hot cakes, dividing them evenly. Let cool completely.
