Making your own Sweetened Condensed Milk in the Thermomix takes only 10 minutes. Using just 4 simple ingredients - full-cream milk powder, white sugar, butter, and water - this recipe yields the same amount as a standard 395g tin and works perfectly in fudge, slices and desserts.
This recipe delivers a creamy, thick consistency with no grainy texture or lumps. Although it costs a bit more than supermarket Homebrands, it's still cheaper than Nestlé, and is a handy emergency backup if you run out.
I use it successfully in both my Thermomix Coconut Ice and Thermomix Salted Caramel Fudge recipes.

Recipe Ingredients
Please see the recipe card at the bottom of this post for the full ingredients and quantities.
Notes on the key ingredients:
- Milk Powder: I've tested this recipe with Woolworths Homebrand and Devondale milk powder. I haven’t tested this recipe with lite milk powder, as many sweet recipes call for full-cream sweetened condensed milk.
- White Sugar: I recommend using white sugar only - either caster or granulated sugar.
- Unsalted Butter: I always use unsalted butter in sweet recipes so I can control the amount of added salt.
Step-by-Step Directions

- Step 1: Add the milk powder, sugar and salt to the Thermomix bowl and mix for 3 seconds on speed 5.
- Add the butter and water.
- Step 3: Cook for 10 minutes, 90℃, speed 3. Place the simmering basket or splatter guard on top of the Thermomix bowl instead of the measuring cup.
- Step 4: Pour the sweetened condensed milk into a container and leave it on the bench top to cool for 20 minutes before storing it in the fridge. See storage notes below.
Sweetened Condensed Milk Tips
Consistency: The sweetened condensed milk will be runny (like custard) just after it has been made but will thicken considerately upon cooling.
Quick Clean Up: Wash the Thermomix bowl immediately after use, to prevent the mixture from sticking. If it does stick, I find that a little bicarb soda mixed with washing up liquid does the trick.
Uses: This homemade sweetened condensed milk can be used as a replacement for tinned sweetened condensed milk in any recipe. Allow it to cool completely before using it in your recipe.
Storage
The sweetened condensed milk will keep for up to 2 weeks in the fridge stored in an airtight container or jar. The mixture will separate slightly, so stir well before using.
If you have any leftover, it can be stored in the freezer for up to 3 months. Thaw in the fridge overnight and stir well before using.
Frequently Asked Questions
Yes, you can. The result will be a slightly darker colour than using white sugar.
It works out to be cheaper than Nestlé, but a bit more expensive than supermarket Homebrands.
Yes, I have made a double batch, and it worked out well. Just increase the cooking time by 3 minutes (so cook for 13 mins/90℃/speed 1) to ensure it's not grainy.
