Introduction

This Crockpot Apple Dump Cake is a healthy, easy, and delicious dessert that requires minimal effort but delivers maximum comfort. Tender apples layered with a golden cake crust and a nutty oat streusel make it a perfect treat for any occasion.

A white plate holds a serving of warm apple crumble topped with a golden brown, crumbly oat and nut topping that looks crunchy. Beneath the topping, tender apple slices are soft and coated in a glossy, light caramel sauce. On the side sits a round scoop of creamy, pale yellow vanilla ice cream, slightly melting onto the crumble. A shiny silver spoon rests on the edge of the plate, and the whole setting is placed on a soft beige cloth over a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

Ingredients

6 medium Granny Smith apples (peeled, cored, and sliced)
1/4 cup granulated sugar
1 teaspoon ground cinnamon
1/4 teaspoon ground nutmeg
1 box yellow cake mix (15.25 ounces)
1/2 cup unsalted butter (1 stick), divided
1/2 cup old-fashioned oats
2 tablespoons light brown sugar

Instructions

Step 1: Lightly grease the slow cooker insert with butter or cooking spray to prevent sticking and ease cleanup.
Step 2: In a large bowl, combine the sliced apples, granulated sugar, cinnamon, and nutmeg. Toss until the apples are evenly coated.
Step 3: Spread the seasoned apples evenly in the bottom of the prepared slow cooker.
Step 4: In a small saucepan over medium heat, melt 2 tablespoons of butter. Cook, stirring occasionally, until it turns golden brown with a nutty aroma. Remove from heat immediately.
Step 5: In a medium bowl, mix 1/2 cup of the cake mix, oats, and brown sugar. Pour the warm brown butter over the mixture and stir until crumbly. Set aside.
Step 6: Sprinkle the remaining yellow cake mix evenly over the apples in the slow cooker, creating a uniform layer without stirring.
Step 7: Distribute the remaining 6 tablespoons of butter over the dry cake mix, either cut into pieces or melted and drizzled for even coverage.
Step 8: Evenly sprinkle the brown butter oat streusel on top of the cake mix and butter layer.
Step 9: Cover the slow cooker and cook on low for 4–5 hours, or on high for 2–3 hours, until the apples are tender and the topping is golden brown and bubbling. Avoid lifting the lid frequently.
Step 10: Turn off the slow cooker and let the dessert rest uncovered for 15–20 minutes before serving to allow it to set slightly.

Tips & Variations

For extra flavor, sprinkle chopped walnuts or pecans into the streusel mixture before topping.
Use a mix of sweet and tart apples if you prefer a more complex apple flavor.
If you like a crunchier topping, add an extra 1/4 cup of oats to the streusel.
Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for an indulgent treat.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven until warmed through. For best texture, avoid reheating in the slow cooker as it may become soggy.

FAQs

Can I use other types of apples for this recipe?

Yes, you can substitute Granny Smith apples with other varieties like Honeycrisp or Fuji, but Granny Smiths provide the ideal tartness and firmness to balance the sweetness.

Is it possible to make this dessert without a slow cooker?

While designed for the slow cooker, you can bake it in a 9×13-inch baking dish at 350°F (175°C) for about 45–50 minutes, or until the topping is golden and the apples are tender.
