Coconut Rum Flan

Coconut rum flan is a creamy, custard-based dessert with a dark caramel top and a hint of tropical rum flavor. The custard sets to a silky texture that trembles slightly when you unmold it, and the contrast between the bitter caramel and sweet coconut custard is what makes it worth the effort.

Ingredients for Coconut Rum Flan

Sugar for the caramel creates a dark, bitter shell that sits on top of the custard. Evaporated milk and sweetened condensed milk make the custard rich and smooth without needing heavy cream. Eggs bind everything together and give the flan its set texture. Coconut extract adds intense coconut flavor so you do not need shredded coconut. Rum brings warmth and depth, balancing the sweetness. Salt cuts through the richness and strengthens the other flavors. Vanilla extract rounds out the taste.

Why This Coconut Rum Flan Works

The flan cooks in a water bath, which keeps the eggs from scrambling and creates an even, gentle heat. The custard will look barely set when it comes out of the oven, with a slight jiggle in the center. It continues to set as it cools and chills, so do not overbake it or it will become rubbery.

The caramel layer sits at the bottom of the pan. When you unmold the flan onto a plate, the caramel flows over the top like a sauce. If you cook the caramel to a dark amber color, it will have a pleasant bitter edge that keeps the dessert from tasting one-note sweet.

Mistakes To Avoid

Undercooking the caramel leaves it pale and too sweet. You want it to be a deep amber color, almost the shade of iced tea. If you stop too early, the flan will taste cloying and the caramel will be hard rather than saucy.

Overbaking the custard makes it grainy and rubbery instead of creamy. The center should still have a slight wobble when you pull it from the oven, about the size of a quarter in the middle of the pan. The eggs will keep cooking from the residual heat, so trust the jiggle test and do not go longer.

Skipping the water bath or using water that is too cool causes the edges to cook faster than the center, giving you a curdled ring around the outside. The water should come halfway up the sides of the baking dish and stay at a gentle simmer the whole time.

Unmolding the flan too soon breaks the caramel layer and makes it stick to the bottom of the pan. The flan must be fully chilled and set, which takes at least 8 hours. Even then, run a knife around the edge and use a plate with a lip to catch the caramel.

Ingredients

• 1 cup sugar, divided
• 1 can (12 ounces) evaporated milk
• 1 can (14 ounces) sweetened condensed milk
• 5 large eggs
• 1/2 teaspoon coconut extract
• 1/4 cup dark rum
• 1/4 teaspoon salt
• 1/2 teaspoon vanilla extract

Step-by-step Instructions

1. Heat the oven to 350°F (175°C). Place a 9-inch round baking dish in a roasting pan and set aside.
2. Pour 3/4 cup of sugar into a heavy saucepan and cook over medium heat without stirring, about 8 to 10 minutes, until it turns a deep amber color (around 350°F on a candy thermometer). Tilt the pan occasionally to even out the heat.
3. Immediately pour the hot caramel into the baking dish, tilting quickly to coat the bottom and partway up the sides. Set aside to cool for 2 to 3 minutes.
4. Whisk together the evaporated milk, sweetened condensed milk, eggs, coconut extract, rum, salt, vanilla extract, and remaining 1/4 cup sugar in a bowl until smooth, about 2 minutes.
5. Strain the custard mixture through a fine sieve into the caramel-lined baking dish.
6. Pour hot water into the roasting pan until it reaches halfway up the sides of the baking dish. Transfer to the oven.
7. Bake for 50 to 55 minutes. The flan is done when the center jiggles slightly when you shake the pan, about the size of a quarter in the middle. The edges should be set.
8. Remove the baking dish from the water bath and let it cool to room temperature, about 1 hour.
9. Cover and refrigerate for at least 8 hours or overnight.
10. Run a thin knife around the edge of the flan and place a plate with a lip on top of the baking dish. Invert quickly and carefully to unmold the flan onto the plate, letting the caramel flow over the top.
