Toss these in the crock with 4 other simple things and watch your family gather round for seconds before dinner's even done.

This 5-ingredient slow cooker vintage plum pudding cake is exactly the kind of dessert I throw together on a busy workday when I still want something cozy and homemade. It borrows its soul from old-fashioned steamed plum puddings—soft fruit, warm spices, and a tender, cakey top—but skips the fuss of boiling basins and hours of babysitting on the stove. You literally toss whole fresh plums into the crock with four pantry staples, flip it on, and let the slow cooker do the work while you handle the rest of dinner. The result is a warm, spoonable cake that tastes like it’s been in the family recipe box for generations, and somehow everyone drifts into the kitchen for “just a taste” before the main course is even ready.

Serve this plum pudding cake warm, straight from the slow cooker, spooned into bowls. It’s perfect with a scoop of vanilla ice cream, a dollop of whipped cream, or a drizzle of heavy cream for that old-fashioned vibe. If you like contrast, pair it with something lightly salty or tangy on your dinner table—like roasted chicken or pork with a simple green salad—so the dessert feels like a cozy, sweet finish. Leftovers are great reheated for breakfast with a spoonful of yogurt or a splash of milk.

Servings: 6-8

8–10 whole fresh plums, firm-ripe, halved and pitted

Lightly grease the insert of a 4- to 6-quart slow cooker with a bit of the melted butter or a quick spray of cooking oil to help prevent sticking.

Prepare the plums by washing them well, then cutting each plum in half and removing the pits. Leave the skins on for color and flavor.

Place the plum halves cut side down in a single, snug layer on the bottom of the slow cooker. It’s okay if they overlap slightly; aim to cover most of the surface. This should look like a bed of whole purple plums nestled into the white ceramic insert.

In a medium bowl, whisk together the flour, sugar, and ground cinnamon until there are no streaks and the mixture looks evenly sandy.

Pour the melted, slightly cooled butter into the dry mixture and stir with a spoon or spatula until it forms a thick, spreadable batter. It will be dense, more like a soft dough than a pourable cake batter.

Dollop the batter evenly over the top of the plums, then gently spread it out with the back of a spoon or spatula to mostly cover the fruit. It doesn’t have to be perfect; the batter will puff and settle around the plums as it cooks.

Cover the slow cooker with the lid. Cook on HIGH for 2 to 2 1/2 hours, or on LOW for 4 to 4 1/2 hours, until the cake top is set, lightly springy in the center, and a toothpick inserted into the cakey part (not the plum layer) comes out with just a few moist crumbs.

Once done, turn off the slow cooker and let the pudding cake sit, covered, for about 10–15 minutes. This rest time lets the juices thicken slightly and makes it easier to scoop.

To serve, spoon down through the cakey top and the soft plums underneath, making sure each portion gets both fruit and cake. Serve warm, with ice cream, whipped cream, or a drizzle of cream if you like.

Keep any leftovers covered in the refrigerator for up to 3 days. Reheat portions gently in the microwave or on LOW in the slow cooker until warmed through.

For a slightly more traditional vintage feel, swap the cinnamon for 1/2 teaspoon ground cinnamon plus 1/4 teaspoon each of ground nutmeg and allspice. You can also add 1 teaspoon of vanilla extract to the batter for extra warmth without changing the ingredient count too much—just reduce the melted butter by a teaspoon if you’re strict about measurements. If your plums are very tart, sprinkle them with an extra tablespoon of sugar before adding the batter for more jammy sweetness. For a nutty twist, finely chop 1/4 cup of walnuts or pecans and press them lightly into the batter before cooking (this technically adds a sixth ingredient, but it’s a nice optional upgrade). If you need to keep things dairy-free, use a neutral-tasting plant-based butter substitute in place of regular butter; just be sure it’s one that’s meant for baking, not a light or whipped spread. Food safety tips: Always wash the plums thoroughly under cool running water and dry them before halving, and use a clean cutting board and knife. Make sure the pudding cake reaches a safe internal temperature (the batter should be fully cooked and not wet in the center). Cool leftovers promptly—within 2 hours of cooking—and refrigerate them in shallow containers. Reheat only what you plan to eat and avoid reheating multiple times to keep the texture and safety in check.
