Coconut Sheet Cake

This Coconut Sheet Cake features a moist, tender crumb flavored with coconut milk and coconut extract, baked in a large sheet pan and topped with a creamy cream cheese frosting infused with coconut extract. The sweet, rich frosting is decorated with shredded coconut and fresh raspberries, adding textural and flavor contrast.

Description

The cake uses a combination of all-purpose flour and cornstarch to create a soft crumb, while coconut milk and coconut extract provide distinct coconut flavor throughout. The batter includes sour cream, which contributes moisture and richness, ensuring the cake remains tender after baking. The sheet pan shape makes it suitable for serving larger groups or casual gatherings.

The frosting combines softened butter, cream cheese, powdered sugar, and coconut extract into a smooth, tangy cream that complements the cake's sweetness. Topping the frosting with shredded coconut adds texture and enhanced coconut aroma, while fresh raspberries introduce a burst of bright, tart freshness to balance the sweet layers.

This cake serves well as a dessert for celebrations or whenever a coconut-flavored cake is desired. Its large format makes it convenient for slicing into generous portions for sharing.
