This Slow Cooker Apple Cider Donut Cake brings all the flavors of your favorite apple cider donuts into one warm, cozy dessert. Made with a spiced cake mix, apple cider, and cinnamon applesauce, it stays moist while cooking slowly. Topped with buttery cinnamon sugar, every bite tastes like fall in a bowl.
In a large bowl, mix together the cake mix, apple cider, applesauce, and eggs until smooth. Pour the batter into the greased slow cooker.
Cover and cook on LOW for 2 to 3 hours, or until a toothpick inserted in the center comes out clean.
In a small bowl, stir together the sugar and cinnamon. Brush the top of the warm cake with melted butter, then sprinkle with the cinnamon sugar mixture.
Serve warm with vanilla ice cream or whipped cream.
