Easy Slow Cooker Apple Blackberry Dump Cake Tips, FAQ & printable recipe

Tips for success

To add extra texture, consider sprinkling a small amount of cinnamon or brown sugar over the top of the cake mix before adding the butter slices. This enhances the apple flavor and adds a deeper color to the final crust.

However, keep these additions minimal to avoid altering the balance of the recipe, as the cake mix already contains sufficient sugar and leavening agents.

For a cleaner presentation, use a large serving spoon to scoop the cake from the slow cooker, ensuring you get a portion of the fruit from the bottom along with the golden crust from the top.

The contrast between the hot, syrupy fruit and the soft, buttery cake is the signature experience of this dessert, so serving it while still warm is highly recommended for the best flavor.

Variations

• Spiced Apple Variation: Add one teaspoon of ground cinnamon and a pinch of nutmeg to the dry cake mix before sprinkling it over the fruit for a warmer, more aromatic flavor profile.
• Crunchy Topping: Sprinkle half a cup of chopped pecans or walnuts over the butter slices before covering the slow cooker to add a pleasant, nutty crunch to the finished dessert.

Storage and make-ahead

Fridge

Store in an airtight container for up to 3 days.

Freezer

Freezing is not recommended as it significantly alters the texture of the fruit and the delicate cake topping.

Reheat

Reheat individual portions in the microwave on medium power until warmed through.

Store any leftover dump cake in an airtight container in the refrigerator for up to 3 days. Ensure the cake has cooled completely to room temperature before covering it to prevent condensation from making the crust mushy.

When ready to enjoy again, portions can be reheated in the microwave, though the texture will be softer than when it was freshly made.

This recipe is best served freshly cooked, but the components can be measured out in advance. Keep the dry cake mix and fruit separate until you are ready to assemble and start the slow cooker.

Avoid assembling the layers hours in advance, as the moisture from the fruit will begin to hydrate the dry cake mix prematurely, potentially resulting in a dense or gummy texture upon cooking.

Serving ideas

Serve the warm dump cake in individual bowls, ensuring each portion includes a generous amount of the fruit filling and the golden buttery topping. The warmth of the dessert makes it a perfect base for a small scoop of vanilla ice cream or a dollop of whipped cream, which provides a cooling contrast to the hot fruit and cake mixture.

This dish is casual by nature and works well for self-service setups. Place the slow cooker on a heat-safe trivet with a large serving spoon nearby. Because it is a dump cake, the presentation is rustic, so focus on the comfort and flavor of the dish rather than perfect plating. It is a hearty dessert that pairs well with coffee or tea after a meal.

Ingredients

• 2 cans apple pie filling
• 2 cups frozen blackberries
• 1 box white cake mix
• 1/2 cup unsalted butter, sliced

Instructions

1. Spread the cans of apple pie filling evenly across the bottom of the slow cooker basin. Distribute the frozen blackberries uniformly over the apple layer, then sprinkle the dry cake mix over the fruit, ensuring it covers the surface completely.
2. Arrange the sliced butter evenly over the top of the dry cake mix. Cover the slow cooker with the lid and cook on high for 3 hours until the fruit is bubbling and the cake topping is golden and set.
3. Turn off the slow cooker and let the dump cake rest for 10 minutes before serving. This allows the juices to thicken slightly and makes it easier to scoop onto plates.
