Ingredients

• 2 cups fresh or frozen cranberries

• 1 box (15.25 oz) yellow cake mix

• 1/2 cup (1 stick) butter, melted

Optional add-ins: 1 teaspoon ground cinnamon, 1/2 cup chopped pecans, a pinch of salt, and whipped topping or vanilla ice cream for serving.

Directions

1. Lightly grease the insert of a slow cooker.

2. Spread the cranberries evenly across the bottom of the slow cooker.

3. In a medium bowl, stir together the cake mix and melted butter (and cinnamon, pecans, and salt, if using) until crumbly.

4. Sprinkle the crumb mixture evenly over the cranberries.

5. Cover and cook on LOW for 2 1/2 to 3 hours (or on HIGH for 1 1/2 to 2 hours), until the topping is set and the cranberries are bubbly.

6. Let cool 15 minutes before serving warm, topped with whipped topping or vanilla ice cream if desired.

Serving Ideas

This buckle is lovely served warm with a scoop of vanilla ice cream or a spoonful of whipped topping. For a cozy dessert plate, pair it with a cup of coffee or hot cider, or drizzle with a little caramel sauce for a company-worthy finish.

Variations & Tips

• Fruit Swap: Frozen mixed berries or apple pie filling work beautifully in place of cranberries.

• Topping Tip: Keep the butter melted but not hot so the crumb topping stays evenly crumbly rather than greasy.

• Add-Ins: A sprinkle of chopped pecans or a pinch of cinnamon in the topping adds extra texture and warmth.

• Storage: Cover leftovers tightly and refrigerate up to 4 days; a few seconds in the microwave brings back that fresh-from-the-oven softness.
