Crockpot Sweetened Condensed Milk

Crockpot Sweetened Condensed Milk
Jump to recipe Sign in to saveAbout 9 hrs 40 minsFrom Scratch

Got milk you need to use up? Turn it into sweetened condensed milk. This recipe is perfect for desserts like cakes, pies, frostings, and no-bake treats – you can even take it a step further and make homemade caramel. While you can make it on the stove, we’ll be focusing on the crockpot method.

This recipe will focus on using whole milk but as a non-dairy girl myself, here are some alternatives:

Variations

Full-fat coconut milk

thick, creamy, naturally sweet; ideal for desserts.

Oat milk

mild, neutral flavor; works well for most recipes.

Soy milk

closest to cow’s milk in protein; thickens nicely.

Almond, cashew, or rice milk

thinner consistency; may require slightly longer reduction.

Butter Alternative

add 1–2 tbsp non-dairy butter or coconut oil for extra richness.

Crockpot Sweetened Condensed Milk

Yield

Yield: About 1 cup – make as much as you need! For example, if you want 3 cups of sweetened condensed milk, just multiply this recipe by 3.

Ingredients

Equipment

  • Whisk
  • Crockpot or saucepan
  • Measuring cups & spoons
  • Silicone spatula
  • Jar for storage

Instructions

  1. Add milk and 1 cup granulated sugar to your slow cooker. Whisk well to fully dissolve the sugar.
  2. Cover and cook on LOW for 6–8 hours, stirring every 45–60 minutes if possible.
  3. The mixture will gradually reduce and thicken to about 1½–2 cups.
  4. Once thick enough to coat the back of a spoon, stir in butter and vanilla.
  5. Let cool — it will thicken more as it cools.
  6. Ready to use after it’s fully cooled. Store in an airtight jar in the fridge for up to 2 weeks. Or pour into an airtight freezer-safe container, leaving ~½ inch headspace. Freeze for up to 3 months.

Notes

  • For making on a stovetop, combine milk and sugar in a medium saucepan over medium heat.
  • Stir constantly until sugar dissolves.
  • Bring to a gentle simmer, lower heat, and cook 15–20 minutes until milk reduces by ~⅓ and thickens slightly.
  • Remove from heat and whisk in butter and vanilla.
  • Cool completely before use.

Philly Cheesesteaks

I’ll be the first to admit that I absolutely hated Philly Cheesesteaks, but not for the reason you might think. It wasn’t the peppers, onions, or melted cheese – it was the chewy meat that’s typically used. No matter how many times I tried it, I just couldn’t get past the texture
