Ingredients Needed
For the cake:
- 2 cups all-purpose gluten-free flour (measure and spoon into the cup for accuracy)
- 1 cup granulated sugar
- 1/2 cup unsalted butter, softened
- 4 large eggs, room temperature
- 1 cup full-fat coconut milk
- 1/2 cup dark rum
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
- 1 cup shredded coconut (sweetened or unsweetened, your choice)
For the frosting:
- 4 oz cream cheese, softened
- 1 cup powdered sugar (confectioners’ sugar)
- 1-2 tablespoons coconut rum (to taste and consistency)
Notes: Let butter and eggs come to room temperature so they mix smoothly. Use canned coconut milk for richer flavor.
How to Make Coconut Rum Cake
- Preheat the oven to 350°F (175°C). Grease a 9-inch round cake pan and line the bottom with parchment if you like. Preheating ensures even baking.
- In a large bowl, beat the softened butter and granulated sugar until the mix looks light and fluffy. This traps air and gives the cake lift.
- Add the eggs one at a time, beating after each addition until the batter looks smooth. This helps the eggs incorporate fully.
- Pour in the coconut milk, dark rum, and vanilla extract. Stir briefly until combined. The liquid adds moisture and rum flavor.
- In a separate bowl, whisk together the gluten-free flour, baking powder, and salt. Mixing dry ingredients separately avoids clumps.
- Gradually add the dry mix to the wet mix. Stir gently and stop when you no longer see streaks of flour. Overmixing can make the cake dense.
- Fold in the shredded coconut with a spatula so it spreads evenly through the batter.
- Pour the batter into the prepared pan and smooth the top with a spatula so it bakes evenly.
- Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean. The cake should be golden at the edges.
- Let the cake cool in the pan for 10 minutes. Then run a knife around the edge, invert onto a wire rack, and cool completely. Cooling in the pan first prevents cracks.
- For the frosting, beat the cream cheese with powdered sugar and add 1–2 tablespoons of coconut rum until smooth. Spread over the cooled cake and serve.

How to Serve Coconut Rum Cake
- Slice and serve at room temperature so the frosting is soft.
- Add toasted coconut on top for extra crunch and color.
- Serve with fresh berries or a scoop of vanilla ice cream for contrast.
- For adults, drizzle a little extra rum over each slice just before serving.
How to Store Coconut Rum Cake
- Room temperature: Cover the cake with a cake dome or plate for up to 1 day.
- Refrigerator: Store in an airtight container for 3–4 days. Bring to room temperature before serving for best flavor.
- Freezer: Wrap slices tightly in plastic and foil, then freeze for up to 2 months. Thaw in the fridge overnight, then bring to room temperature.
Tips to Make Coconut Rum Cake
- Measure flour by spooning into the cup and leveling off to avoid dense cake.
- Use room-temperature eggs and butter for a smoother batter.
- Don’t overmix after adding flour; stop when combined to keep the cake tender.
- If you want less alcohol, reduce the rum in the batter or use coconut extract instead.
- Toast the shredded coconut in a dry pan for 2–3 minutes until light brown for added flavor.

Variation (if any)
- Rum-Free: Replace rum in the batter and frosting with extra coconut milk and 1 teaspoon coconut extract.
- Pineapple Coconut: Fold 1 cup drained crushed pineapple into the batter for a pina colada feel.
- Coconut Glaze: Skip cream cheese and make a simple glaze with powdered sugar and coconut milk.
Helpful Notes
- If your gluten-free flour mix contains xanthan gum and you get a gummy crumb, next time try a blend labeled for cakes.
- Use canned full-fat coconut milk for a richer cake; low-fat versions give less moisture.
- Shredded coconut texture matters—fine coconut disperses more, large flakes give more chew.
