This 4-ingredient slow cooker spring treat is one of those quirky little recipes that makes people do a double-take—and then go back for seconds. Dry, uncooked penne pasta simmers low and slow in sweetened cream and lemon, turning into a soft, custardy, almost bread-pudding-style dessert that feels perfect for spring potlucks, Easter, or backyard get-togethers. It’s the kind of recipe a Midwestern neighbor shares over the fence, and once you try it, you’ll understand why everyone asks for the recipe.
Serve this warm lemon-vanilla penne dessert straight from the slow cooker, scooped into small bowls. It’s lovely topped with fresh berries, a spoonful of whipped cream, or a little vanilla ice cream melting over the top. For a spring gathering, pair it with a simple fruit salad and coffee or iced tea. If you’re setting out a dessert table, this sits nicely next to bar cookies, lemon squares, or angel food cake to keep the flavors light and bright.
4-Ingredient Slow Cooker Spring Penne Treat
Servings: 6-8

Ingredients
2 cups dry uncooked penne pasta
3 cups half-and-half (or whole milk)
1 cup granulated sugar
2 tablespoons fresh lemon zest (from about 2 lemons)
Directions
Lightly coat the inside of a 4- to 6-quart slow cooker with nonstick cooking spray or a thin layer of butter to help prevent sticking.
Pour the dry, uncooked penne pasta into the bottom of the slow cooker insert so it forms an even layer.
In a medium bowl, whisk together the half-and-half, granulated sugar, and fresh lemon zest until the sugar is mostly dissolved and the zest is evenly distributed.
Carefully pour the sweet lemon mixture over the dry penne pasta in the slow cooker, making sure all the pasta is submerged as much as possible. Gently stir to coat, then smooth it back into an even layer.
Cover the slow cooker with the lid and cook on LOW for 2 1/2 to 3 1/2 hours, stirring every 45–60 minutes, until the pasta is very tender and the liquid has thickened into a loose, pudding-like sauce. The mixture will continue to thicken slightly as it cools.
Once the pasta is soft and the sauce is creamy and lightly thickened, turn off the slow cooker. Let the dessert sit, covered, for 10–15 minutes to set up a bit before serving.
Serve warm in small bowls, spooning some of the lemony cream over each portion. If you like, garnish with a little extra lemon zest or a handful of fresh berries on top.
Variations & Tips
For a richer treat, replace 1 cup of the half-and-half with heavy cream. If your family loves vanilla, stir in 1–2 teaspoons of vanilla extract along with the sugar and lemon zest. For a slightly lighter version, you can use all whole milk instead of half-and-half, just know the finished dessert will be a bit looser and less creamy. To add a little texture, sprinkle individual servings with crushed shortbread cookies or graham crackers right before serving. If you have picky eaters who aren’t sure about lemon, reduce the lemon zest to 1 tablespoon and add 1 teaspoon vanilla so the flavor is softer and more like a vanilla pudding. You can also stir in a small handful of white chocolate chips during the last 15 minutes of cooking for extra sweetness. Food safety tips: Keep the slow cooker on LOW as directed; avoid using the WARM setting for the full cook time, as it may not bring the mixture to a safe temperature. Do not leave the dessert sitting at room temperature for more than 2 hours; refrigerate leftovers promptly in a shallow container. Reheat leftovers gently in the microwave or on LOW in the slow cooker with a splash of milk to loosen. Always check that dairy smells and looks fresh before using, and discard any leftovers that smell off or have been left out too long.
