🍯 1-Ingredient Slow Cooker Caramel (Dulce de Leche Magic!)
Omg — this is so good, you won’t believe it’s made with just one ingredient. Yes, really. This Slow Cooker Sweetened Condensed Milk Caramel is one of those rare culinary hacks that feels like straight-up alchemy. With nothing more than a can of sweetened condensed milk and some time, you end up with a luscious, golden caramel that tastes like you stood over a bubbling saucepan for hours — but your slow cooker did all the work.
Known as Dulce de Leche in Latin America and Cajeta in Mexico, this method has been used by home cooks for generations. And once you try it, you’ll understand why. This caramel is thick, silky, sweet, and so versatile that you’ll want to make it on repeat — whether for drizzling, dipping, baking, or gifting.
✨ Why This Works — Culinary Magic in a Can
Chef Maria Lawson, dessert specialist and author of “Sweets from the Slow Cooker,” shares:
“The high sugar and milk content of sweetened condensed milk transforms beautifully under low, steady heat. Over hours, it darkens, thickens, and becomes that creamy, spoonable caramel we love — without stirring, without scorching. It’s as close to foolproof as caramel gets.”
This is one of those make-once-and-always-repeat recipes. Minimal effort, maximum payoff.

👨🍳 How to Make Slow Cooker Caramel (Dulce de Leche)
Step 1: Remove the Label
Take off the paper label from the can. Make sure there’s no glue or residue left on the outside — you don’t want that in your slow cooker.
Step 2: Place in Slow Cooker
Lay the unopened can on its side in the slow cooker. You can add more cans if you’re making a batch.
Step 3: Fill with Water
Fill the slow cooker with water so the can is submerged by at least 2 inches. This prevents any risk of overheating or pressure buildup.
Step 4: Cook on LOW
Set your slow cooker to LOW and cook for 8 hours for a deep, rich caramel. For a lighter, softer version, 6 hours works well.
Step 5: Cool Before Opening
Use tongs to remove the can carefully. Let it cool to room temperature completely before opening — this is important for safety and texture.
Step 6: Open & Enjoy
Once fully cooled, open the can to reveal your homemade caramel. Transfer to a jar or serve directly. Stir in extras like vanilla or sea salt if desired.

⚖️ Comparison: Slow Cooker vs Stovetop Caramel
- Control: Slow cooker provides even heat, no risk of burning
- Effort: No stirring or attention needed for hours
- Batch cooking: You can make several cans at once

❌ Common Mistakes to Avoid
- Opening the can hot: Never do this — hot caramel under pressure can burn you badly

- Skipping cool-down time: Patience is key for safety and consistency
💬 Top 10 FAQs About Slow Cooker Dulce de Leche
1. Can I open the can while it’s hot?
No — let it cool fully before opening to avoid pressure burns and splattering.
2. Can I use a glass jar instead of the can?
Yes, pour condensed milk into a jar, seal tightly, and cook the same way. This is great for small batches.
3. How long does it last?
Unopened: up to 3 months. Opened: store in fridge up to 2 weeks in an airtight container.
4. Can I freeze the caramel?
Yes, freeze in freezer-safe containers for up to 3 months. Thaw in fridge overnight.
5. Can I use light condensed milk?
Yes, but the caramel may be thinner and less rich.
6. Can I add flavorings?
Yes — after cooling, stir in ½ tsp vanilla, a pinch of sea salt, or even a dash of cinnamon.
7. Is this the same as Cajeta?
Not exactly — Cajeta is typically made from goat’s milk, but this is a similar sweet caramel spread.
8. Can I make this in an Instant Pot?
Yes — but it requires slightly different timing and pressure settings. Use the slow cook mode for best results.
9. What happens if I cook it longer?
It becomes darker, thicker, and more toffee-like. 8 hours gives a perfect golden result.
10. Can I reuse the cooked can?
It’s best to transfer caramel to a glass jar after opening. Do not store or cook in used cans again.
