Why You Must Make

Are you caramel phobic? Scared of attempting a homemade caramel sauce? Push those fears aside as I have a simple solution: an easy caramel sauce made in the microwave.

  • Once you’ve done it once or twice, it’s a piece of cake and no candy thermometer is ever needed.
  • I have made numerous varieties of caramels and caramel sauces over the years. And some have been big fat flops. This is the recipe I turn to when I need a no-fail caramel sauce recipe.
  • Plus, it tastes amazing!!

Ingredient Notes

With only a handful of ingredients, make sure they’re high quality for the best results.

  • Corn syrup – Karo is my go-to brand
  • Freshly squeezed lemon juice – Never use bottled lemon juice as the taste is sub-par.
  • Heavy cream – Use cream with at least 36% butterfat
  • Butter – Salted or unsalted will work, but I prefer salted as salt is a flavor enhancer.
  • Vanilla – Use only real vanilla extract, never imitation.

Expert Tips

This is a super easy recipe! Here are a few pointers for making this no-fail microwave caramel sauce at home.

  • PRO-Tip: Since all microwaves heat a little differently, you may have to sacrifice your first batch to figure out the exact timing for your appliance.
  • Sugar, corn syrup, water, and just a teeny squeeze of lemon juice are mixed in a 2 cup Pyrex measuring cup (affiliate link). This concoction is zapped on high heat just until it starts taking on a very pale amber color.
  • PRO-Tip: You’ll want to use a clear Pyrex measuring cup so you can see as the color begins to change.
  • Warning: this hot liquid will continue to cook and brown after it’s removed from the microwave. So, if you let it get to a deeper amber color you will have a burnt mess on your hands.
  • My old microwave took about 4 minutes to reach the ideal color and my current model needs a few seconds more than 5 minutes.
  • PRO-Tip: Make sure to make a note of the timing which gives you the best results for your future batches of this microwave caramel sauce.

  3. Carefully, set the caramel onto the counter where it will continue to bubble and darken to a caramel color (amber).

Frequently Asked Questions

How Should You Store Caramel Sauce?

Although it’s safe to store caramel sauce at room temperature for a day or so, it’s best to keep it refrigerated in an airtight container. It will keep for up to a month in the fridge.
Gently reheat in the microwave to bring it back to pouring consistency before using.

Can You Freeze Caramel Sauce?

Yes, it freezes well. Just make sure you leave room for expansion in your container. Use an airtight container and it will keep well for at least 3 months. It’s best not to freeze in a glass container due to the chance of breakage.

How Do You Make Salted Caramel Sauce?

Start by mixing in 1/4 teaspoon of salt into the warm caramel sauce. Taste and add more salt until it tastes perfect to you. Most likely, the total amount of salt would range from 1/2-1 teaspoon per batch.

Beware that all microwaves are different. My previous microwave would burn well before 5 minutes, and my current one takes about 5 minutes, 5 seconds.
