Use fresh pineapple slices if preferred, but canned pineapple works perfectly and adds extra sweetness. Make sure your butter is at room temperature for easier creaming and better cake texture. Don’t skip the rum extract for authentic pina colada flavor without alcohol. Be gentle when mixing the batter to keep the cake light and fluffy. Let the cake rest for at least 10 minutes before flipping to prevent the topping from sticking to the pan. For a more intense coconut flavor, toast the shredded coconut lightly before adding it to the batter. Variations include using dark brown sugar or maple syrup, gluten-free flour, adding nuts like macadamia or pecans, making a vegan version, or adding other tropical fruits like mango or kiwi.
