Is Condensed Milk Keto?
Definitely not. Regular condensed milk contains about 165 grams of net carbs per cup because it’s made with large amounts of sugar and full-fat milk.
The good news is you can make homemade low-carb condensed milk that tastes very similar to the traditional version and works in a variety of recipes. This keto-friendly alternative has a thick, sticky texture and a perfectly balanced sweetness, making it an excellent substitute in your favorite desserts and drinks.
It’s important to note that regular condensed milk, sweetened condensed milk, and coconut condensed milk from the store are not keto-friendly options.

Ingredients For This Keto Condensed Milk
You only need three simple ingredients — all of which you probably already have in your pantry — to make this rich and creamy keto condensed milk.

- Heavy Cream – This is the base of the recipe, so be sure to use full-fat heavy cream. Half-and-half or milk alternatives won’t work because condensed milk requires a high-fat content to achieve the right texture. If you prefer, you can make keto condensed coconut milk by substituting full-fat canned coconut milk.
- Butter – Use unsalted butter for the best flavor. Make sure it’s at room temperature so it blends smoothly with the cream.
- Sweetener – For the best taste and texture, use a powdered keto sweetener like allulose or powdered monk fruit sweetener. These dissolve easily into the cream, preventing lumps and giving a smooth finish.
How To Make Keto Sweetened Condensed Milk
Once you see how quick and simple it is to make condensed milk at home, you’ll want to keep a batch on hand all the time. Here’s how to do it:

- Heat the Cream – Add the heavy cream to a medium saucepan and bring it to a gentle boil over medium heat, stirring occasionally.
- Add Butter and Sweetener – Stir in the butter and your powdered sweetener (such as allulose or monk fruit). Continue stirring until the butter is fully melted and the sweetener dissolves.
- Simmer and Thicken – Reduce the heat to low and let the mixture simmer gently, stirring occasionally, until it thickens to a creamy, condensed consistency.
- Cool and Store – Pour your keto condensed milk into a clean glass jar. Let it cool to room temperature, then refrigerate until ready to use.

Tip: The condensed milk will thicken even more as it cools. If it becomes too thick after chilling, simply warm it slightly and stir before using.
Tips for Making Keto Condensed Milk
- Use medium heat – Cooking over high heat can cause the cream to burn before it thickens. Keep it at medium and be patient.
- Sift your sweetener – This helps prevent a sandy texture and keeps lumps from forming.
- Stir often – Whisk or stir regularly while cooking to avoid scorching the cream.
- Adjust thickness – If your condensed milk is too thin, simply cook it a bit longer until it reaches the desired consistency.
- Sweeten to taste – Add extra sweetener if you prefer a sweeter flavor.
- Try a brown sugar substitute – For a richer, caramel-like taste, use a sugar-free brown sweetener such as brown monk fruit or brown allulose.
How Can I Use This Keto Condensed Milk
This keto condensed milk is extremely versatile, and can be used for many recipes that call for regular condensed milk. Here are some great ideas:
- Coffee or Tea: Stir it into bulletproof coffee, keto Thai iced tea, classic black coffee, or keto iced coffee for a smooth, sweet flavor.
- Make Keto Ice Cream: Use it as one of the main ingredients in your favorite keto ice cream recipes for a creamy texture.
- Keto Desserts: Perfect for low-carb cakes and sweets like keto tres leches cake or keto German chocolate cake.
- Fresh Fruit – Drizzle over low-carb fruits such as strawberries, raspberries, or blackberries for an easy treat.

Can I Make Instant Pot Keto Condensed Milk?
Yes! If you want to save time, making condensed milk in the Instant Pot is a quick and convenient option.
- Start with the Sauté Function – Select the sauté setting on your Instant Pot. Add the heavy cream and bring it to a gentle boil, stirring occasionally.
- Thicken the Cream – Let it boil for about 10 minutes, stirring often, until it begins to reduce and thicken slightly.
- Add Butter and Sweetener – Stir in the butter and powdered sweetener (such as allulose or monk fruit). Continue cooking on sauté for another 20 minutes, or until the mixture thickens further.
- Cool and Store – Don’t worry if it still seems a little thin; it will continue to thicken as it cools. Transfer to a glass jar and refrigerate.
Tip: Stir frequently during cooking to prevent scorching, as the Instant Pot’s sauté function can get quite hot.

Storing Ideas
- Fridge – Store your keto condensed milk in a clean, airtight glass jar in the refrigerator for up to 1 week. Give it a quick stir before using, as it may thicken while chilled.
- Freezer – You can also freeze keto condensed milk for longer storage. Place it in an airtight container, leaving a little space at the top for expansion, and freeze for up to 1 month. Thaw in the refrigerator overnight and stir well before using.
- Reheating & Restoring Texture – If your condensed milk becomes too thick after chilling or freezing, warm it gently in a saucepan over low heat or in the microwave for a few seconds. Stir well until smooth and creamy again.

I haven’t created a keto version of the Key Lime Pie using your exact regular recipe, but I’ve got a keto Key Lime Pie recipe that’s even easier to make and just as delicious. For the crust, you can use the keto graham cracker recipe from my blog. However, I’m all about keeping recipes simple and accessible to everyone. This approach means you can easily find the ingredients and enjoy making (and eating!) this delicious dessert without any hassle.
