Chef's Notes from Valentina

  • I've tried several brands of protein powder, but Premier 100% whey protein powder in vanilla gave me the best flavor. Choose one you already enjoy because its taste makes a difference in the finished condensed milk.
  • The amount of boiling water depends on the protein powder you use. A blend of whey concentrate and isolate needs less water than 100% whey isolate. For pure whey isolate, use at least ½ cup of boiling water to prevent the mixture from becoming too thick to blend.
  • I have not tested this recipe with plant-based protein powders, so I can't guarantee the same results. Keep in mind that the condensed milk also thickens as it chills, so its texture will change after refrigeration.
  • Keto sweetened condensed milk makes a delicious topping for Coconut Flour Pancakes or Protein Ice Cream. You can also stir it into iced coffee or drizzle it over cakes and crepes.

Ingredients

  • Sugar-free 100% whey protein powder – 1 cup. Use a blend of whey concentrate and isolate for a thick, creamy texture. Its flavor comes through in the finished condensed milk, so choose one you enjoy. Vanilla protein powder works especially well.
  • Granulated stevia or another granulated sugar substitute – ⅔ cup. Adds sweetness without added sugar. Splenda or monk fruit also work. Avoid allulose, which can make the mixture overly thick and sticky, and erythritol, which may recrystallize after chilling.
  • Boiling water – ⅓ cup, or more as needed. Helps the protein powder blend smoothly and controls the thickness. Adjust the amount gradually depending on your protein powder.
  • Vanilla extract – ½ teaspoon, optional. Helps balance the sweetness and complement the flavor of the whey protein powder. You can skip it when using vanilla-flavored protein powder.

Substitutions And Additions

Whey Isolate Keto Condensed Milk: Swap the whey protein blend for 100% whey isolate. Start with ½ cup of boiling water instead of ⅓ cup, and add more if the mixture becomes too thick to blend smoothly.

Coconut Milk Condensed Milk: Use full-fat coconut milk powder instead of whey protein powder for a lower-protein version with a mild coconut flavor. For a dairy-free or vegan option, choose a powder without milk-derived ingredients. Check the carbohydrate content if you're following a keto diet.

Regular Milk Condensed Milk: Replace the whey protein powder with regular milk powder for a more traditional milky flavor. This option contains more carbohydrates, so it's better suited to those who aren't following a low-carb or high-protein diet.

Different Sweeteners: Swap the granulated stevia for Splenda, monk fruit, or another granulated sugar substitute you enjoy. Avoid liquid sweeteners because they can affect the consistency. Finely powdered sweeteners may require a little more to reach your preferred sweetness.

How to Make Keto Condensed Milk

Protein powder poured into a blender cup, mixture blended, and condensed milk transferred to a jar before serving.
  1. Combine the ingredients: Place the protein powder, granulated sugar substitute, and boiling water in a food processor or blender. PIC. 1
  2. Blend until creamy: Blend for 30–60 seconds until the mixture is smooth, creamy, and evenly combined. If it's too thick, add a little more water and blend again. Adjust gradually until the mixture is creamy but neither too thick nor too thin. PIC. 2
  3. Cool and refrigerate: Pour the mixture into a mason jar and let it cool completely before closing the jar and refrigerating. It will thicken further as it chills. PICS. 3 & 4

The Cooking Version of Low Carb Condensed Milk

This cooked version requires different ingredients and is neither high in protein nor low in calories. I have never tested it with protein powder.

  1. Melt the butter: Heat a large saucepan over medium heat and melt 3 tablespoons of unsalted butter.
  2. Add the cream and sweetener: Stir in 1 ½ cups of heavy whipping cream and ⅓ cup of powdered monk fruit sweetener or Splenda until well combined.
  3. Simmer until thick: Bring the mixture to a boil over medium heat, stirring constantly. Reduce the heat to low and simmer for 30–45 minutes, stirring occasionally, until reduced by about half and thick enough to coat the back of a spoon.
  4. Cool and refrigerate: Pour the mixture into a mason jar and let it cool completely before securing the lid and refrigerating.

Expert Tips for Sugar-Free Sweetened Condensed Milk

  • Choose the right sweetener for the cooked version. Avoid erythritol-based sweeteners, such as Swerve, because they can recrystallize after chilling. Allulose can make the mixture overly thick and sticky or cause caramelization, which may prevent desserts from setting properly.
  • Check the ingredients in coconut milk powder. Look for milk-derived ingredients and added carbohydrates before choosing a substitute. A dairy-free powder with a suitable carbohydrate content will better meet vegan or keto dietary needs.
  • Consider the dessert you're making. Use the whey-based condensed milk in drinks, as a drizzle, or in desserts that don't depend on traditional condensed milk for setting. Its different consistency may affect the texture of more delicate fillings.
  • Check the sweetness before refrigerating. Taste a small amount after blending and adjust the sweetener if needed. Sugar substitutes vary in sweetness, and checking early makes it easier to get the flavor you want.
  • Scrape down the blender before transferring. Use a silicone spatula to remove any protein powder stuck to the sides, then blend briefly again. This prevents dry pockets of powder from leaving a grainy texture in the finished condensed milk.

Frequently Asked Questions

What is sweetened condensed milk?

Traditional sweetened condensed milk is made from whole milk and sugar. About half the water is removed through heating to produce a thick, sweet mixture with concentrated milk solids and sugar. For a dairy-free option, try a dairy-free sweetened condensed milk alternative.

Does condensed milk have carbs?

Yes. Regular sweetened condensed milk contains approximately 22 g of carbs per 2 tablespoons. This keto condensed milk contains just 1.8 g of carbs for the same amount.

Is sugar-free condensed milk keto?

Not always. Sugar-free doesn't necessarily mean low-carb. Some versions contain whole milk, which naturally contains carbohydrates from lactose. This sugar-free condensed milk uses whey protein powder and a low-carb sweetener, so it can fit into a keto diet.

    Pretty darn good, but still a little grainy. I used mine as a base for pumpkin spice sauce. Mixed in 1/4 c. Puréed pumpkin, pumpkin pie spice and a little extra brown sugar swerve. Very good substitute.

    1. Hi Sarah! Thank you for your feedback. Mine was thick yet not grainy. I blended mine quite well until smooth! But I have to say I love you used this keto condensed milk to make your pumpkin spice sauce. I will try it myself! Thank you again!

    2. 5 stars
      Super perfect for me. Using sugar substitute is great - I must have looks at 50+ posts for condensed milk w sugar alternative. Many recipes I saw are really awful sounding with all the fat people are using in these items. This one is perfect. Did it extremely easily right in a big cup, not even using a blender, but was ready to if needed: didn't even need it!! Thank you for posting, you have a new fan, especially after reading more of your recipes.
