Ingredients

Instructions

  1. Step 1: Combine 3 cups mixed dried fruits with 2 cups dark rum in a large bowl. Cover and soak at room temperature for at least 1 week, stirring every day to ensure even soaking.
  2. Step 2: Preheat oven to 300°F. Grease and line a 9-inch round cake pan with parchment paper.
  3. Step 3: In a large bowl, beat 1 cup softened unsalted butter and 1 1/2 cups brown sugar until light and fluffy, about 4 minutes.
  4. Step 4: Add 4 large eggs one at a time, beating well after each addition. Stir in 2 tsp vanilla extract and 2 tbsp molasses.
  5. Step 5: In another bowl, whisk together 2 1/2 cups all-purpose flour, 1 tsp ground allspice, 1 tsp ground cinnamon, 1/2 tsp ground nutmeg, and 1 tsp baking powder.
  6. Step 6: Gradually fold the dry ingredients into the wet batter until just combined.
  7. Step 7: Drain the soaked fruits, reserving 1/2 cup of rum. Fold the fruits and 1/2 cup reserved rum into the batter.
  8. Step 8: Pour batter into prepared cake pan and smooth the top. Bake for 2 1/2 to 3 hours, checking after 2 hours and covering with foil if browning too fast.
  9. Step 9: Insert a skewer; if it comes out clean, remove cake from oven. Cool completely before removing from pan.
  10. Step 10: Wrap cake in plastic wrap and store in an airtight container, optionally brushing with additional rum every few days to deepen flavor before serving.
