Almond brittle made in the microwave is a quick and easy thing to make that is so impressive! Itโ€™s a great housewarming present, and itโ€™s great to perch a shard on top of champagne cupcakes, which I did last New Yearโ€™s Eve and thought it was cute! Decorating cupcakes with a crunchy brittle is something I do when I make my small batch chocolate cupcakes, too.

My Mom made microwave brittle with salted peanuts when I was growing up. The baking process is dangerous, though,ย so I wasnโ€™t allowed to help.ย  Iย would watch from a safe distance while the sugar turned from clear to golden.ย  I loved the part when she stirred in the baking soda and the brittle foamed up.ย  So, just because this recipe is easy and consists of dumping 3 ingredients into a bowl and placing it in the microwave does not mean that your kids can help you.ย  Weโ€™re dealing with sugar that is almost 300ย degrees.ย  You should also resist the urge to lick the spoon.ย  It looks like hard candy, but itโ€™s actually hot lava when it comes out of the microwave.

Tips for making almond brittle in the microwave:

  • Please watch your brittle in the microwave while it cooks, especially after you add the almonds. Donโ€™t be afraid to stop the microwave before the 2 minute mark. However, if your sugar turns dark brown or black, itโ€™s ruined. That said, donโ€™t be afraid for the sugar to turn a rich amber color.ย  Sugar must reach a certain temperature before it will set into the proper hardness of brittle.ย  Atย most, you might need to shave 15 seconds off your cooking time.ย  Any more than that and your brittle wonโ€™t set up.ย ย  Use a very deep bowl becauseย boil-overs are disasterous.ย  Also, use raw almonds, or your nuts will taste burntย in the final product.
  • You might fear that your bowl is ruined after youโ€™ve made the brittle.ย  To clean your bowl, simply fill it up with warm water, let it set for an hour and the excess candy will dissolve. No scrubbing required!

Ingredients:

  • Light Corn Syrup.ย When I say light, it means clear, not low calorie. The grocery store has light and dark corn syrup. We need light here.
  • Granulated Sugar.
  • Almonds.ย Unsalted whole, raw almonds are the only thing to use. If the almonds are chopped or sliced (like the ones in my almond bars), it changes the cook time. Please follow the recipe as-stated. If you need a recipe for almond brittle with sliced almonds, please use google and find one.
  • Salt.
  • Butter.
  • Vanilla Extract.
  • Baking Soda:ย Baking soda is what makes brittle crunchy and, well, brittle. The baking soda reacts with the sugar to create carbon dioxide bubbles, which causes it to foam in the bowl. But this foam is what gives the brittle itโ€™s delightfully light and crisp texture.

How to make microwave almond brittle:

  1. First, have ready all of the ingredients (corn syrup, sugar, almonds, salt, butter, vanilla, and baking soda), plus a small baking sheet for pouring the hot brittle on when itโ€™s done cooking the microwave. I like to line a cookie sheet with one of these silicone mats because itโ€™s truly nonstick.

  2. Next, use a large shallow bowl for making this recipe, because the recipe bubbles up several times, and you donโ€™t want it to overflow.ย Add the corn syrup and sugar to the bowl, stir to combine.ย

  3. Microwave for 3 minutes on HIGH. It should be bubbling and boiling quite a lot. See photo.

  4. After the 3 minutes, stir in the almonds and salt. Microwave for another 2.5 minutes. Always keep an eye on it, promise me?

    So pretty, looks so easy and sadly, just burnt the first batch ;(. My microwave is finicky and I thought I caught it but alas, it has to go into the green bin. Will definitely try again. Thanks for this and so many of your recipes, only found you a short while ago and LOVE your sweet treats.

    1. Christina says:

      Oh, Shannon. I know how that goes. Iโ€™m sorry! I bet your microwave runs a bit hot. Try again soon :)

    How can I post my iPhone pic of my first batch? I went on then make batches 2 and 3 but Iโ€™m still laughing at my first attempt. After the first 3 minutes I used my favorite red silicone spoon with a hole cut out in the middle (for better stirring) to mix in the almonds. I left it in the bowl when I put the bowl went back into the microwave. Being mindful that the syrup might burn I watched in amazement as I saw what I thought was the sugar-Karo mixture coming out of the spoonโ€™s handle. It was the red coloring of the spoon oozing into the almond mixture!
    By the time I retrieved the bowl the spoon had melted into 2 pieces and the red coloring blended into the almonds. I made batch 2 according to the recipe and added 3/4c almonds and 3/4tsp salt to batch 3 โ€“ our favorite. mamapelican

    Iโ€™d love to learn how to make an almond brittle that is soft and sweeter, maybe with vanilla flavor. Can you give us a soft brittle recipe?

  4. wathsala says:

    1. Christina Lane says:

      Um, I havenโ€™t tried it that way. Best of luck!

  5. Melissa says:

    Careful ladies, mine started burning just before 2 minutes. Smoke was shooting from my microwave! The texture was nice and I know I wouldโ€™ve loved it if it wasnโ€™t for the burnt taste. I will try again later and just cook to 1 min 50 seconds, and see how that works. Thanks for the simple recipe!

  6. Ava says:

    Wow, this turned out perfect! For someone who rarely has a success with online recipies, this was a pleasant crunchy surprise. (I did not have cornsyrup and adddd a little caramel syrup to wet the sugar).

  7. flgirl says:

    Good small batch recipe for 1 person. Used vanilla sea salt which was amazing and traditional raw peanuts. Already gone, it hardened in less than 5 min.

  8. Jan Amaral says:

    Can you double the recipe?

  9. Mac says:

    I am not seeing exact amounts for the ingredients Iโ€™m not sure how much is in each batch. Example one cup of almonds to one cup of sugar Etc can you please extend those amounts for the recipe thank you. Mac in Colorado
