This slow cooker 4-ingredient jam sponge pudding is the kind of warm, old-fashioned dessert my grandmother would pull out after Sunday dinner—soft, golden, and perfumed with sweet jam. It’s a pared-down take on the classic British jam sponge, but streamlined for busy home cooks and made right in the slow cooker so it stays moist and fluffy. With just a simple batter and a generous layer of jam, you get that melt-in-your-mouth comfort food feeling without a lot of fuss or cleanup.
Serve this jam sponge pudding straight from the slow cooker while it’s still steaming, spooned into warm bowls. A splash of cold heavy cream, a scoop of vanilla ice cream, or a dollop of softly whipped cream plays beautifully against the warm, jammy sponge. For a more traditional Sunday dinner feel, pair it with custard sauce. Coffee or black tea on the side balances the sweetness and makes this feel like a cozy, lingering dessert after a hearty roast or simple weeknight meal.
Slow Cooker Jam Sponge PuddingServings: 6
Ingredients
1 cup strawberry jam (or other favorite jam)
1 cup self-rising flour
1 cup granulated sugar
1 cup unsalted butter, softened (plus a little extra for greasing the slow cooker)
Directions
Lightly butter the inside of a 4- to 6-quart slow cooker crock, making sure to coat the bottom and about halfway up the sides so the sponge releases easily.
Spoon the strawberry jam into the bottom of the greased slow cooker and spread it into an even layer. This will form the jammy base that swirls up into the sponge as it cooks.
In a medium mixing bowl, combine the self-rising flour and granulated sugar. Stir with a spoon or whisk to evenly distribute the sugar through the flour.
Add the softened butter to the dry mixture. Using a wooden spoon, spatula, or clean hands, work the butter into the flour and sugar until it forms a thick, smooth batter. It will seem dense at first, but keep mixing until no dry spots remain.
Gently dollop the batter over the jam layer in the slow cooker, then use the back of the spoon to carefully spread it out to the edges. Try not to disturb the jam too much; a few swirls are fine and will look pretty in the finished pudding.
Place a clean kitchen towel over the top of the slow cooker crock to catch excess steam, then set the lid on top of the towel. This helps the sponge stay fluffy instead of soggy.
Cook on LOW for 2 1/2 to 3 hours, or until the sponge is puffed, golden on top, and a toothpick inserted into the center of the sponge portion (not the jam) comes out clean. Avoid lifting the lid in the first 2 hours so the sponge can rise properly.
Once cooked, turn off the slow cooker and let the pudding rest for about 10 minutes with the lid slightly ajar. This helps it set while staying warm and tender.
Spoon the warm jam sponge pudding directly from the slow cooker into bowls, making sure each serving gets some of the jam from the bottom and the fluffy golden sponge from the top. Serve immediately while steaming hot.
Variations & Tips
If you don’t have self-rising flour, you can make your own by whisking together 1 cup all-purpose flour, 1 1/2 teaspoons baking powder, and 1/4 teaspoon fine salt to replace the self-rising flour in this recipe. Swap the strawberry jam for raspberry, apricot, or mixed berry for a different flavor profile—chunkier fruit preserves will give you pockets of soft fruit in the finished pudding. For a slightly less sweet sponge, reduce the sugar to 3/4 cup; the jam will still provide plenty of sweetness. If your slow cooker runs hot, start checking at the 2-hour mark to avoid overcooking. To add a subtle nutty note without increasing the ingredient list, lightly toast the self-rising flour in a dry skillet over low heat until it smells warm and toasty, then cool before mixing. Leftovers reheat well: spoon into a microwave-safe dish, cover loosely, and warm in short bursts until steaming, then refresh with a little cream or ice cream on top.
