Weeknight Wonder: Just 3 ingredients. Set it and forget it while the house fills with the most heavenly aroma.

This 3-ingredient slow cooker vintage butterscotch lush is the sort of weeknight wonder my mother would have called a “company dessert” even when it was just us kids around the table. It leans on the old Midwestern church-supper trick of letting canned butterscotch pudding and a simple cake mix turn into something far fancier than the sum of its parts. While it bubbles away in the slow cooker, the batter rises up through the pudding, forming a dense, creamy base with a crackled, caramelized top that smells like every good potluck you’ve ever been to. You stir it together in minutes, flip the switch, and let the house fill with that warm butterscotch aroma while you get on with the evening.

Serve this butterscotch lush warm, scooped straight from the slow cooker so you catch those glossy little pools of melted butterscotch on top. It’s lovely all by itself in a small bowl, but a splash of cold heavy cream, a spoonful of vanilla ice cream, or a dollop of lightly sweetened whipped cream makes it feel like Sunday-supper dessert. A cup of hot coffee or black tea balances the sweetness nicely, and if you’re serving a crowd, you can park the slow cooker on “warm” and let folks help themselves as they wander through the kitchen.

Servings: 6-8

1 box (about 15.25 oz) yellow cake mix

Lightly grease the inside of a 4- to 6-quart slow cooker crock with butter or nonstick spray to help prevent sticking and to encourage a nice caramelized edge.

Pour both cans of ready-to-serve butterscotch pudding into the bottom of the slow cooker and spread it into an even layer with a spatula. This will form the dense, creamy base of the dessert.

In a medium bowl, add the dry yellow cake mix. Do not add eggs, oil, or water. Sprinkle in 1/2 cup of the butterscotch chips. Stir just to distribute the chips evenly through the dry mix.

Sprinkle the dry cake mix and chip mixture evenly over the top of the pudding layer in the slow cooker. Do not stir; you want distinct layers so the pudding can bubble up and the top can crackle as it cooks.

Sprinkle the remaining 1/2 cup butterscotch chips evenly over the surface of the dry cake mix. As they melt, they’ll create glossy pools of butterscotch across the top.

Cover the slow cooker with its lid. Cook on HIGH for 2 to 2 1/2 hours, or on LOW for 3 1/2 to 4 hours, until the top looks set and lightly crackled, the edges are bubbling, and a spoon inserted into the center meets a dense, spoonable pudding-cake rather than dry powder.

Once done, turn the slow cooker to WARM and let the dessert rest, covered, for about 15 minutes. This helps the layers settle into a lush, creamy texture while keeping the top slightly caramelized.

Serve warm, scooping down through the crackled top to capture both the dense creamy pudding layer and the golden butterscotch-studded cake. Store leftovers, once cooled, covered in the refrigerator and reheat gently before serving.

For a slightly deeper flavor, you can use a butter or golden cake mix instead of plain yellow, as long as you keep the ingredient count to just the mix, the pudding, and the chips. If you prefer a less sweet dessert, use only 3/4 cup of butterscotch chips and reserve a spoonful or two for sprinkling over each serving instead of the whole top. A pinch of salt sprinkled over the finished dessert will also help balance the sweetness and give it a more grown-up, caramel note. If you can’t find ready-to-serve butterscotch pudding, look for shelf-stable snack cups in the pudding aisle; they work the same way and keep this to three ingredients. For a slightly firmer top, crack the lid open for the last 20–30 minutes of cooking so some steam can escape and the surface can dry and caramelize a bit more. Food safety tips: Keep the slow cooker covered during most of the cooking time so the dessert reaches a safe, hot temperature throughout; lifting the lid too often will extend cooking time and can leave the center undercooked. Once the dessert has cooled to room temperature, refrigerate leftovers within 2 hours to prevent bacterial growth, and reheat only what you plan to eat, returning any unused portion promptly to the refrigerator. Always make sure your slow cooker is in good working order and that the cord and plug are intact before using.
