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 made these today and didn’t realize until too late that I had forgotten to buy corn syrup- so I subbed honey for all the corn syrup and it worked perfectly and the caramels have a lovely honey flavor! I’ve subbed half honey for corn syrup in caramels before but never 100%. Mine took a little longer than 7 minutes, probably due to the honey. An instant-read thermometer is a must with this recipe, I think. Sprinkled French grey sea salt on top. So much faster than the stove top! I used a large glass batter bowl with a handle which worked perfectly.

    HELP!!! These taste absolutely wonderful, but I can’t get them to set up!!! I made them two days ago, putting them in the fridge, etc and they are just sticky messy! I’m loving the taste and have eaten with a spoon, but I wanted to give some away and it’s just not working!! What could I be doing wrong that they’re not setting up? Cooked too long or not long enough???

      It sounds like they just need to cook a bit longer, caramel that is too soft usually just didn’t get hot enough or in other words didn’t cook long enough.

  • Lori

    I can’t get them out of the pan!! I covered the bottom and sides in butter first

  • Jane

    I made these today and the flavor is amazing but they are so hard. I don’t know what I did wrong. I’m going to try again but do you have any suggestions? Thanks and Merry Christmas :)

      You may just have a high wattage microwave oven so they cooked faster than most. I would just cut it back maybe 30 seconds and if they were super hard then 1 minute. Hope that helps!

    I made these today and they turned out great! I was skeptical because I have made caramels on the stove forever and they burn a lot. Not the case here! I used my instant read thermometer which I could not live without and got mine to 240℉ which was perfect. I also had Maldon sea salt flakes which are amazing. Thanks for a great recipe.

      Hi Nicole,
      Where does one get an “instant read thermometer” as described in your post?
      Thanks,
      Dolores

        You can get them at the grocery store or also places like Walmart/target. They are usually in the baking isle.

  • Joanne Newland

    I made these from your recipe….I couldn’t believe it, Perfect ! I have now done three batches…And yes perfect every time…My husband and I use to do this the old fashioned way…stand & stir forever it seemed…You rock ! Best and easy…thank you so much…

  • Kim

    I’ve tried for years to make caramels and they NEVER work out. I’m a professional cake decorator & long time baker & pride myself on my baking skills but I’ve always been bummed I’ve never made a batch of caramels that turn out. Until now!! I made two separate batches of these caramels & they both turned out perfect! It’s a flippin’ Christmas miracle!!! You, Jaclyn, & your mother in law are angels to share such a foolproof caramel recipe! Thank you so much!!!

      I’m so glad they turned out for you Kim! Thanks for your comment! Merry Christmas!

    Do you think using margarine instead of unsalted butter would affect the recipe?
