This quick and delicious Microwave Caramel Sauce recipe is a no brainer. Making it homemade is infinity times better than a store-bought sauce, and this recipe takes literally 5 minutes, so I can make it all day every day.

I’m not proud.

How to make Homemade Caramel Sauce IN A MICROWAVE!

Traditional caramel sauce requires candy thermometers, and a little stress in my opinion. SO I am here to day to simplify the whole process. If you’ve never made caramel sauce, this is a perfect recipe to start.

What Ingredients You Will Need:

  • Heavy Cream: This is the base for the sauce, and heavy cream makes the sauce rich and silky.
  • Vanilla: Use Pure Vanilla extract in this recipe. The vanilla really shines through!
  • Butter: I use salted butter in this recipe, because I prefer a Salted Caramel. Salted Butter along with an extra pinch or two of salt will give you that yummy salty/sweet balance.
  • Brown Sugar: I use brown sugar in this recipe (which TECHNICALLY makes this a butterscotch sauce) because we’re not boiling the sugar, as in a traditional homemade caramel sauce. Cooking the sugar on the stove top is what gives it that deep amber color which we know in caramel, but since this is a short cut recipe, you get the color from brown sugar. I’m not made about it.
  • Salt: You can use kosher or sea salt in this recipe to make it a Salted Caramel Sauce, which I highly recommend. Use as much or as little as you like, but make sure you stir it in enough so it all dissolves and doesn’t settle to the bottom.
Ingredients for simple microwave salted caramel sauce

The Simple Steps:

  1. First melt your butter and add in the brown sugar and cream. You can do this all in one bowl, but make sure the bowl has high sides, because it will bubble up in the microwave!
  2. Whisk the caramel mixture until it’s combined and then pop it in the microwave for a few minutes, stirring once.
  3. And this is when I add a little salt to make it homemade SALTED caramel sauce! Make sure you stir the salt in enough for it to dissolve.
  4. Add in your vanilla last and stir to combine.

Pro Tip: The caramel will seem a bit thin at first. Just keep whisking it and it will thicken as it cools. You can always reheat it for a few seconds if it gets too thick.

I like to store this in cute little Mason Jars so I can pretend like I live in Pinterest, but as long as it’s air tight, it will be fine in the fridge for up to a week!

    Easy peasy. Homemade caramel sauce in under 10 minutes. I used it immediately for my iced caramel latte.

  2. Nancy Cook Tracy

    Oh my, this was quick, easy and delicious! Seriously missing desserts during these crazy times! Didn’t have heavy cream, used milk with a wee bit more butter. Great on popcorn!
