This 3-ingredient slow cooker sugar cone dessert turns broken sugar cones into a warm, gooey treat with buttery crunchy edges. You’re going to love how easy it is—just sugar cones, sweetened condensed milk, and butter. Serve it warm with vanilla ice cream, whipped cream, or fresh berries.
Why You’ll Love It
- Only 3 main ingredients — broken sugar cones, sweetened condensed milk, and butter.
- No oven needed — the slow cooker keeps the kitchen reasonably cool.
- Soft and crunchy texture — some cone pieces turn tender and pudding-like while others stay toasted and crisp.
- Makes about 6 servings — especially good with vanilla ice cream or fresh berries.
- Great for using up broken cones — no need to let those crumbs go to waste.
Ingredient Notes
You need plain sugar cones here, the light tan crispy kind with the little grid pattern. Not waffle cones, which are thicker and richer and would change the whole thing. I suppose they might work in a pinch, but waffle cones rarely become leftovers.
Sweetened condensed milk is non-negotiable. Please don’t grab evaporated milk by mistake. The results are thin, sad, and frankly a little insulting. Sweetened condensed milk is thick and sticky and does the job of binding all those cone pieces together.
For butter, I use unsalted because that’s generally what I keep around for baking. Salted butter works too, though. It may even be nice if you like that sweet-salty thing.
You’ll also need a little extra butter or nonstick spray to grease the slow cooker. That isn’t really a “fourth ingredient,” unless we’re being fussy.
Ingredients
- 6 cups broken sugar cones, uncooked and loosely packed—some larger chunks, some crumbs; use what you’ve got
- 1 can (14 ounces) sweetened condensed milk, the regular full-fat kind
- 4 tablespoons unsalted butter, melted
- A little butter or nonstick cooking spray for greasing the slow cooker insert
Instructions
- Lightly grease the bottom and sides of a 4- to 6-quart slow cooker with butter or nonstick spray. Do not skip this unless you enjoy soaking a crock overnight and then pretending you’ll deal with it tomorrow. Tomorrow is a liar.
- Pour the 6 cups of broken sugar cones into the bottom of the slow cooker and spread them out into a fairly even layer. A mixture of fine crumbs and chunky pieces is exactly what you want here—those uneven bits give the finished dessert its soft-and-crunchy personality.
- In a small bowl or glass measuring cup, whisk the sweetened condensed milk and melted butter together until smooth. It will be thick, shiny, and smell so good you may briefly consider eating it with a spoon. Resist. Or don’t.
- Slowly pour the condensed milk mixture all over the broken sugar cones, trying to cover as much of the surface as you can. It does not need to look perfect. Nothing in the kitchen looks perfect after about 4:30 in the afternoon.
- Use the back of a spoon or a spatula to gently press the cone pieces down into the sweet mixture so they are lightly moistened. Do not stir everything into a paste; leave some pieces sitting up and some tucked down in the liquid so you get those lovely pockets of crunch later.
- Put the lid on the slow cooker and cook on LOW for 2 to 2 1/2 hours, until the edges are golden and set and the center is soft and gooey but not runny. Try not to lift the lid more than once. Each peek lets heat out and stretches the cooking time.
- When it is done, switch the slow cooker to WARM and let the dessert rest for 10 to 15 minutes. That little rest gives it time to thicken up enough for scooping, and it also helps prevent burns.
- Scoop the warm sugar cone dessert into bowls and serve with vanilla ice cream, whipped cream, or fresh berries if you like. Cold milk is good alongside it, and coffee is even better if you’re eating this after dinner while pretending you are only having “a little taste.”
Variations
If you want a deeper caramel sort of flavor, stir 1 teaspoon of vanilla extract or a small pinch of salt into the condensed milk and butter before pouring it over the cones. That is still basically the same easy dessert, just wearing a nicer blouse.
Scatter about 1/2 cup mini chocolate chips or chopped pecans over the cone pieces before the milk mixture goes in. The plain version is wonderful, too. The cones have enough going on by themselves.
Fresh strawberries, blueberries, sliced peaches—those are all wonderful on top, especially in summer.
You can reduce the condensed milk to about 10 ounces if you prefer a drier, crunchier result, checking it right around the 2-hour mark.
Low-fat sweetened condensed milk can be used if that is what you have. Just don’t substitute regular milk or evaporated milk. It will not thicken properly, and then you’ll have sugary cone soup. There are worse things, but not many.
Storage & Reheating
Leftovers should be transferred to a shallow container and refrigerated within 2 hours. Don’t leave the slow cooker sitting on WARM all evening, even though it seems harmless. The warm setting is for holding the dessert briefly after it cooks, not for keeping it around until midnight while the kitchen stays open for snacking.
It keeps in the refrigerator for a couple of days, though the crunchy pieces soften more overnight. Cold leftovers have their own strange little appeal. Like cold pizza, only sweeter and less likely to ruin your waistband.
To reheat, microwave individual portions just until warm. Start with 20 or 30 seconds and see where you are. It can go from cozy to lava in a hurry. If it has been sitting out at room temperature for more than 2 hours, especially when it’s warm outside, toss it. I hate wasting food, but I hate spending the night regretting dessert even more.
Final Notes
There is something satisfying about turning a bag of broken cones into something worth making again. Maybe it’s the thriftiness of it. Maybe it’s that old habit of making do with what’s in the pantry. Or maybe it’s just because sweetened condensed milk has never let me down, unlike certain cable companies and most pairs of white socks.
This dessert works especially well when the house feels busy and everything is happening at once. Set out bowls, spoon the warm dessert into them, and add melting ice cream for a simple treat that brings everything together.
Anyway. Save those broken cones. They’ve got one more good thing in them.
