This slow cooker 3-ingredient chocolate Kensington is the kind of old-school dessert recipe that feels almost too simple to work, and then somehow turns into the warm, fudgy centerpiece everyone talks about all night. It has that clipped-from-the-newspaper charm that makes you want to try it at least once, especially when you need a low-effort dessert for a potluck or backyard get-together. I love recipes like this on busy weeks because you can stir everything together in minutes and let the slow cooker handle the rest while you focus on everything else.
Serve this warm with scoops of vanilla ice cream, a spoonful of whipped cream, or a handful of fresh berries to balance the deep chocolate flavor. If you are bringing it to a late summer gathering, it also pairs well with coffee after dinner or a glass of cold milk for the kids, and it is especially nice alongside lighter barbecue favorites since the texture lands somewhere between cake and hot fudge pudding.
Slow Cooker 3-Ingredient Chocolate Kensington
Servings: 8
Ingredients
1 box chocolate cake mix
1 box instant chocolate pudding mix
3 cups whole milk
Directions
1. Lightly grease the inside of a 4- to 6-quart slow cooker. In a large mixing bowl, whisk together the chocolate cake mix, instant chocolate pudding mix, and whole milk until the batter is smooth and no dry pockets remain.
2. Pour the batter into the prepared slow cooker and smooth the top with a spatula so it cooks evenly.
3. Cover and cook on high for 2 to 2 1/2 hours, or until the edges are set and the center is still soft and fudgy. Avoid lifting the lid too often, since that can slow the cooking time.
4. Turn off the slow cooker and let the dessert rest uncovered for 10 to 15 minutes. Spoon it into bowls and serve warm.
5. For a simple party presentation, serve each portion with vanilla ice cream or whipped cream if you like.
Variations & Tips
Make it extra rich: Swap 1 cup of the milk for heavy cream if you want an even deeper, silkier texture. This is a great option for holiday dinners or when you want the dessert to feel a little more decadent.
Add a flavor boost: A teaspoon of vanilla extract or a pinch of espresso powder is not part of the original 3-ingredient version, but either one can make the chocolate taste even fuller without adding much extra work.
Check early on newer slow cookers: Some slow cookers run hotter than older models, so start checking around the 2-hour mark. You want a set edge and a spoonable center, not a fully dry cake.
Make ahead tip: You can mix the batter a few hours ahead and refrigerate it in the bowl, then pour it into the slow cooker when you are ready to start dessert. That trick has saved me more than once before having friends over after work.
Serving for a crowd: This dessert stretches nicely if you offer small bowls and a topping bar with whipped cream, berries, or chopped nuts. It is rich enough that a modest scoop usually satisfies everyone.
