Empty the entire can of sliced peaches, along with the juice, into a 6-quart slow cooker.
Evenly sprinkle the cake mix over the peaches.
Next, add the crushed walnuts, cinnamon, and nutmeg on top. It’s important not to mix the ingredients.
Distribute the small slices of butter evenly over the mixture.
Cook on high heat for approximately 2 hours.
Serve the delicious dessert with a scoop of vanilla ice cream.
