Microwave Peanut Brittle – Homemade Nut Brittle for the Holidays

This microwave peanut brittle is simple to make but looks like you made a trip to the candy shop. It comes together in just minutes and tastes amazing. Homemade nut brittle is one of our favorite Christmas recipes

This microwave peanut brittle is ready to set in less than 20 minutes and tastes amazing.

Nothing says Christmas to me quite like walking into a candy store and buying a box of peanut brittle.  The sweet, hard caramel surrounding crunchy peanuts is a real treat!

Christmas is such a busy time of the year, and most homemakers spend a lot more time in the kitchen than normal. Having a microwave version of a traditional holiday classic sweet treat saves time and tastes just as good as the stove part recipes do.

For a decadent touch, try dipping the peanut brittle pieces into melted dark chocolate.  Your party guest will love this version!

There are lots of recipes for making peanut brittle at home, but most of them need a candy thermometer or have a water drop step as part of the instructions.

This recipe for homemade peanut brittle is an updated version of the traditional stove top classic but is made in the microwave. Gone are the days of making candy like this:Candy thermometer

Making Microwave Peanut Brittle

The difference with this recipe is that the brittle is made in the microwave, not on the stove top, so there is no need for the old fashioned water drop method, that I must admit I do not care for.  Soft ball?  Hard ball?  I never seem to get it just right.

I like the taste of dry roasted peanuts, so I used them in this recipe, but really any sort of nut that is your favorite will work as well. The recipe is faster with shelled nuts but whole nuts give a fresher taste, so they could be used, too.

Raw peanuts can also be used, but they normally have no salt, so extra salt (or salted butter) would be great additions to the recipe.raw nuts in shells

One of the great things about making this homemade nut brittle in the microwave is how quickly it comes together.  20 minutes and you are ready to let it harden!

Start by heating the sugar and corn syrup in the microwave for 3 1/2 to 5 minutes. I give it all a good stir after the first 2 minutes.

Mix in the peanuts and continue heating for another 2-4 minutes. The mixture will get a golden brown color and you know that it’s just about ready.

Add the butter and vanilla and cook for another minute.

The last step is to stir in the baking soda.  You’ll be surprised to see the whole thing foam with this step.

Spread the mixture onto a large baking sheet lined with a silicone baking mat or parchment paper, and let it harden.peanut brittle layer

Once the homemade nut brittle has hardened, break it into pieces.

Why is my microwave peanut brittle chewy?

If you find that the texture of your peanut brittle is chewy and not crisp and firm, the reason is most likely that you didn’t cook it long enough.

Even in the microwave, the peanut brittle has to reach the hard crack stage, so that the sugar strands will break easily and not feel sticky.

The next time you make it, cook it for a little longer.

A note on cooking times:

Microwaves vary a great deal as to how long to cook sugar.  Start with less minutes than I ask for and heat in increments.  It is easy to burn if your microwave heats more quickly than mine does.

Homemade Microwave Peanut Brittle

This microwave peanut brittle is simple to make but looks like you made a trip to the candy shop. Homemade nut brittle is a favorite of ours at the holidays.
Prep Time 20 minutes
Cook Time 10 minutes
Total Time 30 minutes

Ingredients

  • 1 cup granulated sugar
  • 1/2 cup light corn syrup
  • 1 1/2 cups of dry roasted peanuts (other nuts such as almonds, macadamia nuts, pecans, or hazelnuts will work too.) I used the salted dry roasted peanuts.
  • 1 tablespoon of unsalted butter
  • 1 teaspoon pure vanilla extract
  • 1 teaspoon baking soda
  • OPTIONAL:
  • melted dark chocolate

Instructions

  1. Heat the sugar and the corn syrup in the microwave on high for 3 1/2-5 minutes, stirring after the first 2 minutes.
  2. Add the peanuts and continue heating for another 2-4 minutes until the mixture is a golden brown color.
  3. Add the butter and vanilla. Stir until the butter is melted and microwave another minute.
  4. Stir in the baking soda (the mixture will foam with this step.)
  5. Spread the mixture onto a large baking sheet. Cool completely and then break into pieces.
  6. Optional: dip the peanut brittle in melted dark chocolate for a decadent touch to the peanut brittle recipe

Notes

Please note: microwaves vary a great deal as to how long to cook sugar. Start with less minutes than I ask for and heat in increments. It is easy to burn if your microwave heats more quickly than mine does.

The range of cooking times that I give is for microwaves in the 900-1100 power range.

      Hi Terry. I am sorry to hear that this happened. When I cooked mine it turned out fine. Microwaves to vary a great deal as to how long things cook. I’ll update my directions so that readers won’t have this happen to them. Thanks for letting me know.

    I have been making a version of this recipe for years with 3 different (1000 watt) microwaves with perfect results. Measurements are the same with the addition of 1/2 t. salt with the peanuts. Cook times are, sugar & syrup for 3 1/2 min, add peanuts and cook another 2 1/2 min. add butter & cook for another minute. Add sofa & pour into pan.

      On the first microwave round, with only the sugar and syrup, when your heating for 3 1/2 minuets, do you stop and stir after 2 minuets like she says in the recipe?

      Thanks!

        Hi Heather, I always stir every so often when I make anything with sugar in it in the microwave. Carol

    This brittle is perfect & I promise you it’s very quick & easy! I’ve made this (or similar) for a few years, & the only suggestions I would make are: 1. REALLY grease your pan beforehand with butter (makes it a lot easier to get out). 2. Make sure you have all your ingredients PREMEASURED & close to hand, (you’ll thank me later!) 3. Use a large GLASS bowl to heat your ingredients. My first time making this I used a plastic bowl & the bowl MELTED!!! A waste of ingredients & a real mess to clean up. ( I personally use a 2 qt.- size measuring cup. These are only suggestions, the REAL praise goes to CAROL & THE GARDENING COOK!!! ?

    I have made this a lot and it is very good but I would like to try the coconut in it so how much do you put in the recipe

    • Carol
      02/15/2017 at 4:02 pm

      Hi Minnie. I have never made it with coconut so I’m not sure how much to add. It would be a question of trial and error to get it the way you like it. Carol

    I always use parchment paper for candy making instead of butter- personal preference. It’s easy cleanup and the candy doesn’t get the greasy bottom. This is a great recipe and I’ve been making it for years.

    I make micro always, my micro is 900 watts, and my recipe is for 900 watts
    Peanut brittle very good .I have hard time pouring out to get it thin enough,
    You have to work so fast ..

    • Carol
      12/14/2017 at 1:14 pm

      I find that too, Betty. But working fast is also a sign that it will set well! Carol

    Dry roasted…salted or unsalted?

    • Carol
      12/21/2017 at 3:12 pm

      HI Edwina. Either works fine, but I used the salted ones. Carol

    Carol,
    Thank you so much. We use an 1100 watt and used 3 1/2 on the first then 3 on the peanuts and 1 on the butter and Vanilla. I loved the way it foamed up I was like a kid. This is the easiest we tried the old fashion way it id did not taste good. My husband said it taste like I bought it at an old time candy store.

    Thank you so much.

      Hi Kathy. Thanks for your time and wattage. So glad you enjoyed the recipe! Carol

    We use an 1200 watt microwave not sure how long to cook it with that wattage. Carol could you address my question please.

    • Carol
      02/23/2018 at 11:21 am

      Hi Linda, I can’t say for sure sine my oven is a bit lower than yours. I”d try it at 3 minutes for the first step with sugar and corn syrup and then maybe 1 1/2 minutes for the second with the peanuts and 30 seconds for the third step with the vanilla and butter.

      You can if you would like too. It should still work. Carol
