Before you start
Before beginning, ensure your slow cooker is clean and dry. Prepare the fruit by washing the plums thoroughly, removing the pits, and slicing them into uniform half-inch thick wedges.
Having your ingredients measured and ready before you start layering ensures the process remains quick and efficient, preventing the fruit from oxidizing while you prepare the topping components.
Ingredients at a glance (4)
- 4 cups fresh black plums, sliced
- 1 can (21 oz) apple pie filling
- 1 packet (15.25 oz) spice cake mix
- 1/2 cup unsalted butter, thinly sliced
Instructions
Layering the base
- Prepare the fruit basePlace the sliced black plums at the bottom of the slow cooker. Pour the apple pie filling over the plums and spread it out evenly to create a uniform fruit layer.Look for The fruit should cover the bottom of the cooker evenly.Tip Ensure the plum slices are of similar thickness for even cooking throughout the process.
The fruit base should be arranged in an even layer at the bottom of the slow cooker. Ensure the plums are spread out so they cook evenly. This phase is complete once the fruit and apple pie filling are combined and ready for the dry topping.
Adding the topping
- Add the toppingSprinkle the dry spice cake mix over the fruit layer, ensuring it covers the plums and apples completely. Arrange the thin slices of butter evenly across the top of the cake mix.Look for The dry mix should be distributed without large clumps remaining.Tip Do not stir the ingredients; the cake mix needs to sit on top to steam correctly.
The cake mix must be spread in a thin, even layer covering the fruit completely. The butter slices are the final addition. Check that the butter is distributed across the entire surface to ensure even melting and browning during the cooking cycle.
Slow cooking
- Cook the cobblerCover the slow cooker and cook on high for 3 hours or until the topping is golden brown and the fruit is bubbling. Allow the cobbler to rest for 10 minutes before serving.Look for The top should appear set and golden, and the fruit juices should bubble at the edges.Tip A longer rest period allows the juices to thicken slightly, making the cobbler easier to serve.
At the end of the cooking time, the cobbler should be steaming and fragrant. The top should be golden brown, and the fruit underneath should be soft and syrupy.
Allow it to rest for ten minutes, which helps the juices thicken and makes serving cleaner.
Common mistakes
Avoid the temptation to stir the ingredients. Stirring disrupts the layering that allows the cake mix to steam properly; instead of a coherent crust, you will end up with a gummy, uneven texture.
Additionally, ensure the butter slices are distributed evenly across the surface. Clumping the butter in one area leads to uneven browning and may cause parts of the cake mix to remain dry and floury.
How to tell it’s done
The cobbler is finished when the top layer of cake mix is golden brown and no longer appears powdery. The fruit mixture should be bubbling vigorously around the edges of the slow cooker.
Because there are no raw proteins involved, you are looking for visual cues of cooked, tender fruit and a set, cake-like crust rather than an internal temperature.
