This coconut rum cake recipe is a boozy and delicious dessert that's perfect for adult parties. The cake is moist and tender, with a rich coconut flavor that's enhanced by a rum glaze. To make this cake, you'll need flour, sugar, baking powder, salt, coconut milk, butter, eggs, vanilla extract, and rum. Mix the dry ingredients together, then add the wet ingredients and mix until smooth. Pour the batter into a greased bundt pan and bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool before glazing with a mixture of powdered sugar, rum, and coconut milk. Garnish with shredded coconut and serve.
