Piña Colada Cake with Coconut Lime Glaze

A tropical layer cake combining pineapple, coconut, and rum in a tender crumb, finished with a silky coconut-lime glaze. The cake suspends fresh pineapple chunks midway through baking, creating moist pockets throughout. Dark rum adds depth without overpowering, while lime zest brightens both cake and glaze. Best for warm-weather gatherings, dessert buffets, or anyone craving island flavors in cake form. This version uses both coconut sugar and granulated sugar for complex sweetness, with fresh lime juice replacing extract.

Tips
Cream butter and sugars thoroughly until pale and fluffy to incorporate air, ensuring a tender crumb and better rise.
Layer pineapple midway through batter so fruit stays suspended and creates pockets of moisture without sinking.
Good to Know
Cover tightly and refrigerate up to 4 days. Glaze keeps cake moist; unglazed cake dries faster. Freeze unfrosted cake up to 3 months; thaw overnight before glazing.
Bake cake 1 day ahead, cool, wrap tightly, and glaze the next day for fresher-tasting glaze. Glaze can be made up to 2 hours before pouring.
Room temperature, sliced with a warm knife for clean cuts. Pairs well with whipped coconut cream, vanilla ice cream, or a dark rum punch.
Common Mistakes
Overmix batter after adding flour to avoid a dense, tough crumb.
Skip foil covering to prevent dry, overbrowned top; remove foil for final 10-15 minutes if browning too fast.
Pour hot glaze over warm cake to avoid cracks; always cool cake completely first.

FAQ
Can I use canned pineapple instead of fresh?
Yes, use drained canned pineapple in the same weight. Reduce coconut milk in the glaze by 1 tablespoon as canned fruit releases more moisture. Flavor will be slightly sweeter and less bright.
What if my glaze is too thick?
Whisk in additional coconut milk or lime juice, 1 teaspoon at a time, until it reaches pouring consistency. Glaze thickens as it cools, so aim for slightly loose texture when warm.
How long can I keep this cake?
Covered at room temperature for 2 days; refrigerated for up to 4 days. The glaze keeps it moist longer than unfrosted cake. Freeze unglazed cake up to 3 months; thaw overnight before glazing.
