2/3 cup good-quality caramel sauce, warmed
2 ripe Bartlett pears, peeled, cored, and sliced
3/4 cup cranberries
1 cup flour
1/4 cup sugar
1/2 teaspoon salt
1 teaspoon baking powder
1 cup milk
2 tablespoons butter, melted
1. Coat the cooking insert of a 5- to 6-qt. slow-cooker* all over with cooking-oil spray. Evenly spread caramel on bottom, then top with an even layer of pears. Sprinkle with cranberries.
2. Whisk together flour, sugar, salt, baking powder, milk, and butter in a medium bowl until mostly smooth with only tiny lumps remaining. Pour over fruit and spread with a spatula to cover evenly.
3. Cover and cook until a toothpick inserted in cake portion comes out clean, about 1 hour and 20 minutes on high or 2 1/4 hours on low.
4. Remove basin from slow-cooker and let pudding cake cool 5 minutes. Spoon onto plates, pear side up, and dollop with crème fraîche.
*You can use a 4-qt. slow-cooker, but may need to increase the cooking time.
