My sister makes this for every spring gathering. Just 3 ingredients for this fun and fluffy dessert

This slow cooker 3-ingredient confetti cake is exactly the kind of dessert I lean on when life is busy but I still want something fun and homemade on the table. My sister actually started this tradition—she brings this cake to every spring gathering, from Easter brunch to backyard cookouts, and it disappears fast. It’s fluffy, moist, and packed with rainbow sprinkles, but the best part is how hands-off it is: just three simple ingredients and your slow cooker does all the work while you tackle the rest of your day.

Serve this confetti cake warm right out of the slow cooker, scooped into bowls like a soft, fluffy cobbler. It’s especially good with a scoop of vanilla ice cream or a dollop of whipped topping that melts into all the little sprinkle-dotted pockets. For spring gatherings, I like to add a handful of fresh berries on the side and set out small bowls of extra sprinkles so everyone can decorate their own serving. Coffee, hot tea, or a cold glass of milk are all perfect pairings with this sweet, nostalgic dessert.

Servings: 8-10

1 (15.25-ounce) box white cake mix

Lightly coat the inside of a 4- to 6-quart slow cooker with nonstick cooking spray to help prevent sticking and make cleanup easier.

In a medium mixing bowl, add the dry white cake mix and pour in the milk. Stir with a whisk or spatula just until the batter is mostly smooth and no big dry pockets remain; a few small lumps are okay. Avoid overmixing so the cake stays light and fluffy.

Gently fold in the rainbow sprinkles with a spatula, using just a few strokes so the colors don’t bleed too much into the batter. Reserve a small spoonful of sprinkles if you’d like to sprinkle some on top after cooking.

Pour the batter into the prepared slow cooker and spread it into an even layer, nudging it into the corners and edges. Smooth the top with the back of a spoon or spatula.

Place a clean kitchen towel or a couple of paper towels over the top of the slow cooker insert to catch excess condensation, then put the lid on securely. This helps keep the cake surface fluffy and prevents it from getting soggy.

Cook on HIGH for 1 1/2 to 2 1/2 hours, or on LOW for about 3 to 3 1/2 hours, until the edges are lightly golden, the center looks set, and a toothpick inserted into the middle comes out clean or with just a few moist crumbs. Try not to lift the lid during the first hour so the cake can rise properly.

Once done, turn off the slow cooker and carefully remove the lid, lifting the towel away so the condensation doesn’t drip back onto the cake. Let the cake sit, uncovered, for about 10 to 15 minutes to set and release some steam.

If you reserved extra sprinkles, scatter them over the warm cake surface for a fresh pop of color. Serve the cake warm, scooping it straight out of the slow cooker with a large spoon into bowls. Store any leftovers covered in the refrigerator for up to 3 days, reheating individual portions gently in the microwave.

For a slightly richer cake, swap the whole milk for half-and-half or use 1 cup milk plus 1/4 cup sour cream stirred into the batter; it will come out extra moist and tender. You can also change the vibe of the cake just by switching up the cake mix: a vanilla, French vanilla, or yellow cake mix all work with the same amount of milk and sprinkles. If you want more confetti throughout, sprinkle an extra tablespoon of jimmies over the batter right before putting the lid on. To keep the cake from overbrowning on one side (some slow cookers run hot in certain spots), rotate the insert halfway through the cooking time if it’s safe and easy to do with your model. For a light glaze without adding another formal ingredient, warm a few spoonfuls of store-bought frosting (any flavor you like) in the microwave until pourable and drizzle a thin layer over each serving instead of frosting the whole cake. Around spring holidays, I’ll sometimes mix in pastel-colored sprinkles or top each bowl with a couple of mini chocolate eggs to make it feel extra festive while still keeping the recipe itself to just three simple ingredients.
