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.

    This recipe is outstanding! I’ve made in so many times and it’s quick and easy. Thank you! Also, if you ever try doubling it, will you please post any adjustments you make? Thanks!!

  • Jean

    I read through the comments and I didn’t see what wattage of microwave that was used. Mine is 1200 wattage.

    Bonjour ,

    où trouve t on du sirop de maïs car c’est la première fois que j’en entends parler .
    Sinon comment le remplacer ?
    Merci

  • Diane

    Tried these today and they are amazing and so easy! My last attempt with another recipe; not so great. Asked hubby to taste and he said “well, you know me, I’m not a caramel person”. Then he proceeded to eat about five of them!! They are delicious. Great gift/hostess gift idea. Who doesn’t love homemade candy??

    Hello ! Thanks for sharing your mother in law recipe (Those amazing mother in low recipes.. I love my m-i-l cooking !!!)
    Found on Pinterest, but had to translate it in French. So for your french reading fans, here is the translation :
    Caramels
    Micro-ondes

    Rendement: Environ 40 caramels

    Ingrédients

    1/2 tasse de beurre non salé (Pas de beurre salé il éclabousse terriblement)
    Sirop de maïs léger 1/2 tasse
    1/2 tasse de sucre granulé
    1/2 tasse de cassonade candi
    1/2 tasse de lait condensé sucré
    1 p. de sel
    3/4 cc extrait de vanille
    Fleur de sel (facultatif)

    Marche à suivre

    Beurrer un plat pyrex de 8 pouces.

    Placez le beurre dans un grand récipient allant au micro-ondes, enclencher jusqu’à ce que ce soit fondu.

    Ajouter le sirop de maïs, le sucre blanc, la cassonade, le lait condensé sucré et le sel et mélanger au fouet soigneusement.

    Replacer le récipient dans le micro-ondes et cuire le mélange à puissance maximum 6 à 7 minutes
    Je vous recommande de commencer par 6 minutes et de tester soit avec un thermomètre à confiserie 238 à 242 degrés F (ou 110 à 120 °C) , soit en plongeant une petite cuillère du caramel dans un bol d’eau glacée, cela doit former une petite boule souple -… Rien de trop mou ou trop dur.
    Si la masse a besoin d’un peu plus de cuisson, remettez-la au micro-ondes, 20 secondes à la fois et testez à nouveau votre masse.
    Mes caramels ont été cuits en 6 minutes 20 secondes, mais la cuisson varie légèrement en fonction de la puissance de votre micro-ondes et la taille du bol que vous utilisez).

    Utiliser des maniques, retirez prudemment le bol du micro-ondes.

    Ajouter l’extrait de vanille et bien mélanger.

    Verser le mélange dans le moule préparé.

    Saupoudrer légèrement de sel de mer ou de fleur de sel.

    Placez au réfrigérateur environ 20 – 30 minutes.

    Coupez en bâtonnets ou en carrés et emballer dans des rectangles de papier sulfurisé ou ciré.

    Have a blessed day !

    I’ve never made caramels before I found your recipe. I’ve made them rwice now. It’s so simple & so delicious! It makes such a big batch I give them away by the handfulls at work. People come by desk looking for them now. I’m going to use this recipe to make caramel filled chocolates.

      I’m so glad you and your lucky co-workers have enjoyed the recipe Elizabeth! So nice of you to share, I want to hoard them all away for myself :).

  • SisJane

    Would u please let me know it corn syrup may be replaced with maple syrup? Thank u

    • Jaclyn

      Jaclyn Bell

      I wouldn’t recommend it, maple syrup and corn syrup cook differently and also have a different consistency.

    After I tried a recipe with the pot on the stove and the candy therometer and a fail (too hard and burned on the bottom) I thought I’d try this easy way. WOW! So much easier and taste great! I used parchment paper in my 8×8 pan and should have buttered the paper cause it stuck something awful! I may just butter the glass 8×8 next time. Followed the recipe for time and cold water to check hardness but maybe could have cooked just a little more? But they are holding their shape in the wax paper wraping. I lightly buttered the cutting board before I put it on to cut but 24 hours later they are not sticking to the wax paper wrap. I cut the carmels in half and doubled them before I cut them into pieces because they were quite thin. Made 24 large pieces.
