Keto Sweetened Condensed Milk

Making your own sweetened condensed milk at home might sound intimidating, but this keto-friendly version is surprisingly simple. With just four ingredients and a little patience, you’ll have a rich, creamy, and perfectly sweetened mixture that can be used in dozens of recipes.

Whether you’re prepping a batch of Peppermint Keto Fudge, planning a holiday dessert, or just looking for a better option than the canned version, this keto sweetened condensed milk does the job. It’s thick, smooth, and nearly identical to the traditional version—without the sugar or unnecessary additives.

Why This Version Works So Well

Traditional sweetened condensed milk relies on simmering milk and sugar together until it reduces into a thick, caramelized syrup. This version takes a similar approach, using heavy cream for richness and allulose for sweetness and consistency.

Allulose is the ideal choice here because it behaves like real sugar when heated. It browns, thickens, and melts into the cream without crystallizing. Paired with a small amount of xanthan gum, it creates that thick, silky texture you’d expect—without any strange aftertaste or grittiness.

The butter adds a touch of depth and smoothness to balance everything out, bringing this low-carb version closer in flavor to a traditional dulce de leche-style condensed milk.

Ways to Use Keto Sweetened Condensed Milk

Once it’s made, you can use it in tons of different ways. It adds richness and sweetness to both baked goods and no-bake treats, and it even works in drink recipes if you’re going for something creamy and decadent.

• Use it in low-carb fudge or truffle recipes
• Drizzle over berries or keto pancakes
• Stir into iced coffee for a creamy boost
• Layer into frozen desserts or cheesecake cups
• Mix into fat bombs or creamy fillings

Storage & Shelf Life

After cooling, transfer the sweetened condensed milk to a glass jar or sealed container. It should be stored in the refrigerator and used within one week. If you find it thickens too much when cold, let it sit at room temperature for a few minutes or warm it gently to restore its pourable texture.

Freezing isn’t recommended for this recipe, as the texture may not hold up well once thawed.

A Simple Addition That Opens Up More Recipes

This is one of those recipes that’s worth learning even if you only need it occasionally. Once you’ve made it once, you’ll see just how easy it is to keep a batch on hand for keto desserts and treats. It’s especially helpful if you like experimenting in the kitchen or need a staple that helps recreate more traditional recipes without all the sugar.

Instead of skipping recipes that call for sweetened condensed milk, you can now adapt them and still get great results. One quick prep session, and you’re set for the week.
