Ingredients You’ll Need
· 2 cans (14 oz each) whole berry cranberry sauce
· 1 box (15.25 oz) white cake mix (dry, unprepared)
· 1/2 cup unsalted butter, melted
Optional add-ins: 1/2 cup chopped pecans or walnuts, 1 teaspoon vanilla extract, 1/2 teaspoon cinnamon, 1/4 teaspoon nutmeg, 1/2 cup white chocolate chips, orange zest for brightness
Note: For a gluten-free version, use gluten-free cake mix. For a dairy-free option, use plant-based butter. Yellow cake mix or spice cake mix also work beautifully. Do not prepare the cake mix—use it dry, straight from the box.
Step-by-Step Instructions
- Layer the Cranberry Sauce: Spread the whole berry cranberry sauce evenly across the bottom of the slow cooker. Use a spatula to create a smooth, even layer. The whole berry sauce provides texture and beautiful ruby-red color.
- Add the Cake Mix: Pour the dry cake mix evenly over the top of the cranberries, covering the entire surface. Do not stir—the layers need to stay separate for the magic to happen. Gently smooth the top if needed, but don’t press down.
- Drizzle with Butter: Drizzle the melted butter evenly over the dry cake mix. Try to cover as much of the surface as possible. The butter will soak into the cake mix as it cooks, creating a tender, golden topping. Do not stir.
- Cook Low and Slow: Cover and cook on LOW for 3-4 hours or HIGH for 2 hours, until the cake is set, golden, and the fruit is bubbly around the edges. The aroma will be incredible.
- Rest Before Serving: Turn off the slow cooker and let it rest uncovered for 10 minutes to allow the cake to set slightly. This helps the topping firm up and makes serving easier.
- Serve Warm: Serve warm, spooned into bowls, and topped with a scoop of vanilla ice cream if desired. The contrast of warm cake and cold ice cream is absolutely divine.
Tips for the Best Slow Cooker Cranberry Dump Cake
· Don’t Stir: The layers must stay separate. Stirring prevents the cake from baking properly and creates a gummy texture.
· Use Whole Berry Cranberry Sauce: Whole berry sauce provides texture and visual appeal. Jellied sauce works but creates a smoother, less textured layer.
· Spread Butter Evenly: Try to drizzle the melted butter as evenly as possible to ensure all the dry cake mix gets moistened. Use a spoon to spread if needed.
· Check at Minimum Time: Slow cookers vary. Check at the minimum cooking time and look for golden, set cake and bubbly edges.
· Let It Rest: The 10-minute rest allows the topping to set and makes scooping easier.
· Add Crunch: Sprinkle chopped pecans or walnuts over the cake mix before adding the butter for a nutty crunch.
Variations & Substitutions
· Cherry Dump Cake: Use 2 cans cherry pie filling instead of cranberry sauce. Add 1/2 teaspoon almond extract.
· Apple Dump Cake: Use 2 cans apple pie filling and add 1 teaspoon cinnamon to the cake mix.
· Peach Dump Cake: Use 2 cans peach pie filling and sprinkle cinnamon sugar over the top.
· Blueberry Dump Cake: Use 2 cans blueberry pie filling and add 1 teaspoon lemon zest.
· Pumpkin Dump Cake: Use 1 can pumpkin puree mixed with 1 can evaporated milk and 3/4 cup sugar as the base. Use spice cake mix.
· Chocolate Cherry Version: Use chocolate cake mix instead of white for a chocolate-cherry combination.
Frequently Asked Questions
Can I use a different flavor of cake mix?
Absolutely. White cake mix is classic, but yellow, spice, butter pecan, or even chocolate cake mix all work beautifully. Choose a flavor that complements the cranberry—spice cake is especially good for holidays.
Can I make this in the oven instead?
Yes! Layer the ingredients in a 9×13 inch baking dish. Bake at 350°F for 40-45 minutes, until the top is golden and bubbly. The slow cooker version is great for convenience, but the oven works just as well.
Do I need to prepare the cake mix?
No. Use the cake mix dry, straight from the box. Do not add eggs, oil, or any other ingredients listed on the package. The butter and fruit juices will moisten the mix as it cooks.
Can I use frozen cranberries instead of canned sauce?
Yes, but you’ll need to create a sauce first. Simmer 4 cups fresh or frozen cranberries with 1 cup sugar and 1/2 cup water until the berries burst and the mixture thickens. Use this as the base layer.
How do I store leftovers?
Store in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 30-45 seconds, or reheat the entire dish in the slow cooker on LOW for 1 hour.
Can I freeze this dessert?
Yes! Cool completely, transfer to a freezer-safe container, and freeze for up to 2 months. Thaw overnight in the refrigerator and reheat in the microwave or oven.
What can I serve with dump cake?
Vanilla ice cream is the classic pairing. Whipped cream, heavy cream, or a drizzle of caramel sauce also work beautifully. For a festive touch, sprinkle with powdered sugar or add a dollop of brandied whipped cream.
Why is my cake mix still dry?
This usually means the butter wasn’t distributed evenly enough or the cooking time was too short. Make sure to drizzle butter over all the dry mix and cook until the top is golden and set. If needed, add a few extra tablespoons of melted butter.
