The Easiest Caramel Recipe Ever!

Oh the things you can make in the microwave! Honestly though, I don’t know if it gets much better than this one, caramel made in the microwave. I got this recipe from my mother-in-law and it is one of my favorite recipes ever!

This is caramel made easy and they taste completely perfect. She’s used this recipe for about 30 years and she said everyone she gives the recipe to absolutely loves it and I can see why.

She also said it’s so easy that her kids always used to make it when they were younger (adult supervision required here though people, this bowl gets HOT!). And now my kids love to help me make it, and we’ve been using the recipe for 4 years.

I’ve added a few minor changes to the recipe, like adding some vanilla and adding Maldon sea salt, add them if you’ve got them otherwise feel free to leave them out.

Try a batch this weekend, you’ll be amazed!

Showing how to make caramel. Whisking butter, corn syrup, sweetened condensed milk, salt and sugar in glass mixing bowl.

Ingredients for Caramel

  • Unsalted butter
  • Light corn syrup
  • Granulated sugar and brown sugar
  • Sweetened condensed milk
  • Salt 
  • Vanilla

 

Heating butter, sugar, condensed milk mixture in glass mixing bowl in microwave to make caramels.

How to Make Caramels

  • Butter an 8 by 8-inch baking dish.
  • Place butter in a large microwave safe bowl (not anything plastic, something micro safe glass or ceramic), heat in microwave until melted.
  • Add corn syrup, granulated sugar, brown sugar, sweetened condensed milk and salt and whisk mixture very well. R
  • Return to microwave and cook mixture on HIGH power for 6 to 7 minutes (some have even mentioned 5.5 worked for them).
  • Using hot pads, carefully remove bowl from microwave. Mix in vanilla.
  • Pour mixture into prepared baking dish and sprinkle with flaky sea salt if desired.
  • Let set in refrigerator then cut into pieces and wrap.

Tips for This Recipe

  • Use unsalted butter, salted butter will splatter.
  • Test caramel at 6 minutes instead of going to the full 7 minutes. To do so test with a candy thermometer (should be 238 – 242d) or you can drop a small spoonful in ice water and after just a bit is should be pliable and chewy.

My first batch was too hard because I went the full 7 minutes, the time will vary based on your microwave wattage and the how large the bowl is you’re using.

Can you believe it though, caramels made in 7 minutes in the microwave!? Trust me, I’m hanging onto this recipe forever, and I’m thinking you will too!

Microwave Caramels

A super easy foolproof recipe for homemade caramels! They're soft and chewy and perfectly buttery with a rich caramel flavor. These make one of the best homemade gifts and no one will know how easy it was for your to make them!
Servings: 40 caramels
Prep10 minutes
Cook6 minutes
Chill20 minutes
Ready in: 36 minutes

Ingredients

Instructions

  • Butter an 8 by 8-inch baking dish. Place butter in a large microwave safe bowl (that is microwave safe to high temps such as heavy duty glass**), heat in microwave until melted.
  • To bowl with butter, add corn syrup, granulated sugar, brown sugar, sweetened condensed milk and salt and whisk mixture very well. 
  • Return to microwave and cook mixture on HIGH power for 6 to 7 minutes.***
  • Using hot pads, carefully remove bowl from microwave. Add in vanilla extract and mix well.  
  • Pour mixture into prepared baking dish, sprinkle top lightly with Maldon sea salt or fleur de sel if using. 
  • Place in refrigerator until set, about 20 - 30 minutes. Cut into rectangular pieces (I cut into rows slightly less than 1/2-inch then cut each row into three) and wrap in cut rectangles of wax paper.

Notes

  • *Don't use salted butter or it will splatter a lot.
  • **For safety I recommend referring to the bowls manufacturer to ensure the bowl is microwave safe to high temperatures. For safety avoid setting on a cold surface after removing from the microwave and be sure that you don't begin with a cold bowl or it could shatter.
  • ***I recommend taking it out around 6 and testing either with a candy thermometer which should register between 238 - 242 degrees or placing a small spoon of the caramel in a bowl of ice water then remove it from the water and it should have formed a small pliable ball - nothing too soft or too hard.
  • ***If it needs a little more time return to microwave and heat in 20 second increments. Mine was done at 6 minutes 20 seconds but will will vary slightly based on the wattage of your microwave and the size of the bowl you use.

    I just made some of the caramels today. I spray tin foil and it is easier taking them out of the pan. Just grab the ends and lift them out. they are ready to be wrapped. That is the worse part. I wrap in waxed paper.

  • Jordan

    I made these and they turned out great and delicious. My only problem is that they are sticking to the wax paper when I try and unwrap them to eat. I’m not gonna lie I’ve probably eaten was paper at this point. What can I do?

  • brenda

    I made these the other day and they came out so good. Everyone loved them. Super easy, mine was done after 6 min. 20 sec. It took longer to cut and wrap them than to make them. Thanks for a great holiday recipe.

    Will these caramels turn sugary or grainy after a few days? I make fudge in the microwave and find it works great as well and is smooth, not grainy.

  • Louise

    Thanks for the recipe. I wonder though, why do you suppose salted butter make it spatter, but salt doesn’t?

      I’m not exactly sure the science behind it but it’s the same issue when I brown salted butter, it starts spattering as well.

    What wattage is your microwave? I just made this and I have a 700 watt. Complete fail over here, like usual for me. I’ve heated and heated and heated. Probably going to end up throwing this away since nothing seems to be working. Suggestions please? Thank you.

    I would love to make these to give away for Christmas. I was just wondering how early can I make them before Christmas? How many does one batch make when cut long?
