Lactose Free Condensed Milk Recipe: Rich Creaminess Without Dairy

This lactose-free version delivers the same thick, sweet richness as traditional condensed milk. It’s perfect for baking, desserts, or coffee when dairy isn’t an option.

With just a few simple ingredients and 20 minutes of cooking time, you’ll have a creamy, caramel-colored substitute that stores well in the fridge for up to two weeks.

Ingredients for Lactose Free Condensed Milk

Six simple ingredients transform into a dairy-free condensed milk with rich, caramelized sweetness.

The coconut milk is non-negotiable here—full-fat canned (like Thai Kitchen or Native Forest) delivers the thickness and creaminess you need. Light coconut milk or carton versions won’t reduce properly. The sugar should be fine granulated; avoid powdered or brown sugar as they’ll alter the texture. For the vegan butter, Miyoko’s or Earth Balance are reliable brands that melt smoothly without separating.

No coconut milk? Cashew cream (blended soaked cashews with water) can work but requires straining for smoothness. Sugar substitutes like maple syrup or agave won’t give the same caramelized depth—stick with granulated. If you’re out of vanilla, almond extract at half the amount adds a nice floral note. The baking soda is subtle but essential for that classic condensed milk tang.

Store in a clean glass jar in the fridge for up to 2 weeks. It thickens further as it cools. For longer storage, freeze in ice cube trays for 3 months. Stir well before using as some separation is natural.

Step-by-Step Instructions for Lactose Free Condensed Milk

This method transforms simple ingredients into a rich, dairy-free condensed milk with professional results.

Step 1: Combine and Heat the Base Ingredients

In a medium saucepan with a heavy bottom, combine the 2 cups Coconut Milk and 0.75 cup Granulated Sugar. The full-fat canned variety works best here as it provides the necessary richness and creaminess that mimics traditional condensed milk.

Place the saucepan over medium heat and stir constantly with a silicone spatula until the sugar fully dissolves. This should take about 3-4 minutes. Watch for the mixture to come to a gentle simmer, but don’t allow it to boil vigorously at this stage.

Step 2: Incorporate the Aromatics and Leavening

Once the sugar has dissolved, add the 2 tbsp Vegan Butter, 0.25 tsp Baking Soda, and 0.125 tsp Salt. The baking soda plays a crucial role here—it helps caramelize the sugar and creates a subtle depth of flavor.

Stir well to combine all ingredients, ensuring the vegan butter melts completely. The mixture will begin to foam slightly as the baking soda reacts. Continue stirring for an additional 2 minutes to fully integrate these components before proceeding.

Step 3: Simmer and Reduce to Desired Consistency

Reduce the heat to medium-low and let the mixture simmer gently. At this stage, switch to occasional stirring to prevent sticking while allowing the mixture to thicken. The goal is to reduce the volume by about one-third, which typically takes 25-30 minutes.

You’ll notice the color deepen to a light caramel hue and the texture become more viscous. The mixture should coat the back of a spoon thickly when it’s ready. If it reduces too quickly or starts to darken too much, lower the heat slightly.

Step 4: Finish with Vanilla and Cool

Remove the saucepan from heat and stir in the 1 tsp Vanilla Extract. The pure vanilla extract adds a layer of complexity that elevates the final product. Be cautious here—the hot mixture will release a strong vanilla aroma.

Transfer the mixture to a heatproof container and let it cool to room temperature, about 1 hour. As it cools, it will thicken further. Once completely cool, it should have the consistency of traditional sweetened condensed milk, ready for use in any recipe calling for this ingredient.

Common Mistakes When Making This Recipe

Boiling Over

Never walk away while simmering—this mixture can foam up and overflow quickly, especially once the baking soda is added. Keep heat at medium-low and stir frequently. I learned this the hard way with a stovetop covered in sticky caramel.

Wrong Coconut Milk

Using light coconut milk or carton versions won’t work—they lack the fat content needed for proper thickening. Stick to full-fat canned like Thai Kitchen. The difference in texture is dramatic. 💡

Rushing the Reduction

Patience is key during the 25-30 minute simmer. Cranking the heat to speed it up will cause scorching and a burnt flavor. Trust the process—the color deepens gradually to that perfect caramel hue.

Skipping the Baking Soda

It might seem optional, but ¼ tsp baking soda is crucial for that classic condensed milk tang. Without it, your result will taste flat. The small amount won’t leave a soapy flavor—just the right balance.

Over-sweetening

Stick to exactly ¾ cup sugar—more will make it cloying and throw off the texture. The sugar caramelizes during cooking, creating depth. I’ve ruined batches by trying to make it “extra sweet.”

Improper Cooling

Let it cool completely at room temperature before refrigerating. Putting hot mixture in the fridge can cause condensation and water down your creation. It thickens significantly as it cools, so resist the urge to rush. ❄️
