Soft apple cake layered with creamy vanilla custard and warm cinnamon flavor for a lighter dessert that feels truly indulgent.
A Creamy, Better-For-You Apple Dessert
Apple Custard Cake is the perfect combination of a tender apple cake and a creamy custard dessert in one beautiful recipe. Traditional custard cakes often rely on heavy cream, lots of sugar, and refined ingredients, but this lighter version uses Greek yogurt, oat flour, fresh apples, and a naturally sweetened custard layer to create a more balanced treat. The cake stays moist with applesauce and yogurt, while the homemade custard adds a silky texture without the need for heavy cream. Packed with warm cinnamon, vanilla, and juicy apples, this dessert is lower in calories, higher in protein, and perfect for breakfast, brunch, afternoon tea, or a healthier dessert option during apple season.
