Microwave Peanut Brittle Recipe (2)

My mother-in-law’s friend, Leo, makes the most addicting peanut brittles that I’ve ever had! It’s sweet and nutty, melt-in-your-mouth crunchy. I don’t know if that last part make any sense at all, but it basically means it’s not rockhard, orstick-to-your-teethchewy that you’d pray not to lose a teeth while eating it.

No, nothing like that. Instead this peanut brittle has light and airy texture with the most satisfying crunch.

Every Christmas my MIL shares her bag of treats from Leo with me, because she knows how much I love them. Well, this past January she brought yet another bag full of amazing brittles for me and my mom.

My mom lovedthose brittles so much so she insisted me to call Leofor the recipe, and I obliged. Don’t know why it took me so long, butI’m so glad I did.

And today I’m going to show you how to make the easiest and most addicting candy ever. Ready?

Microwave Peanut Brittle Recipe (3)

As I said earlier, these are the easiest peanut brittles in the world! No exaggeration here, because 1. You don’t need candy thermometer. 2. No stirring sugar mixture over hot stovetop for a long time. 3. It only takes 10 minutes of hands on time, one bowl with a lid, a microwave, and handful of simple ingredients.

Here’re my tips and tricks for success:
  • Prepare and measure out all the ingredients before starting. The process goes super quick and you want that margarin, thatbaking soda right now!
  • Speaking of margarin. Yes, you do need margarin. And no, you can’t use butter, I tried it tono avail. (<- I got rock hard brittles!) I gave in and bought a package of margarin just for this recipe, but it’s so worth it.
  • Microwave-safe bowlwith a lid is essential. Leo stressed that the bowlhas to have a lid, or you’ll risk burning the mixture.
  • Baking soda is what makes the candy so airy and light. After mixing in soda, the mixture will foam up. Don’t be alarmed, because it’s a good thing. Don’t take too much time mixing though, just a few good stirs until the mixture is evenly foamed up and pour it on a buttered baking sheet. I use 2 forks to spread it out evenly, but nottoo thin.
  • Directions on timing in this recipe are for 1000Watt microwave.

I now know the recipe by heart, as I’ve made countless batches to feed my mom’s craving. I even sent some to my sisters back in Mongolia, and they all loved it. Well, I mean, what’s not to love here??

FAQs

Why is my microwave peanut brittle chewy? ›

Store your microwave peanut brittle in an airtight container at room temperature. Avoid storing in the fridge because any condensation could make the brittle chewy.

How to make peanuts in the microwave? ›

Pour into small microwave safe casserole or pie plate. Microwave for 2 1/2 minutes; stir, microwave 2 1/2 minutes longer. Peanuts will be crisp when cool. CAUTION: Cooking time necessary may vary with ovens; remember, peanuts continue to cook as they cool.

Why did my peanut brittle not get hard? ›

The main reason why peanut brittle doesn't get hard and have the crunch we expect is because the sugar was not cooked long enough. The sugar needs to be cooked to what is called the hard crack stage, 300ºF.

Why put baking soda in peanut brittle? ›

In theory, it's a good idea, the baking soda adds some air to the caramelized sugar, making the sheets of candy more brittle, but it also introduces a minerally, metallic taste that's off putting to say the least. My version of peanut brittle is ridiculously simple to make, and leaves out the baking soda.

How do you keep peanut brittle crispy? ›

Store the brittle in an airtight container at room temperature for up to 1 month to maintain the crisp. Moisture in the refrigerator would soften the brittle.

How do you fix crumbly peanut brittle? ›

Reviving stale peanut brittle is possible to some extent. You can try placing the stale peanut brittle on a baking sheet and gently heating it in an oven at a low temperature, around 250°F (120°C), for a few minutes. This can help to soften it a bit and restore some of its original texture.

How long do you microwave peanuts? ›

For a light roast, microwave on HIGH for 2-1/2 minutes; stir, microwave 2-1/2 minutes longer. For a darker roast, stir and microwave 1 minute longer, in 30 second increments. Season to taste. Peanuts will be crisp when cool.

Can roasting be done in the microwave? ›

Cooking times were considerably shorter in the microwave ovens than in the conventional ovens. Reduced power was used for microwave cooking of roasts, except that rib eye roasts were cooked at full power for the first 5 min.

Why do you have to soak peanuts before boiling them? ›

Some recommend soaking the raw peanuts for several hours (6-8) in salted water to reduce cooking time. I've never soaked them myself but if you have time, and plan ahead, give it a go. To begin the cooking process, fill a large stock pot with water, add salt and bring to a boil then add the peanuts.

How do you make peanut brittle easy? ›

Melt butter in a saucepan over medium heat. Stir sugar and salt with melted butter to dissolve completely. Remove saucepan from heat, add peanuts, and stir to coat completely; immediately pour onto prepared pan and spread into an even layer. Refrigerate until brittle, at least 30 minutes.

Why is my peanut brittle still soft? ›

Didn't get it hot enough. You have to hit hard crack stage heat or it's not going to harden. From internet: Hard-Crack Stage is a cooking term meaning that a sugar syrup being heated has reached 149 – 154 C (300 – 310 F.) It is a test of how hot a sugar syrup is, and of how much water is left in it.

Why is my peanut brittle not fluffy? ›

It is important to coat cookie sheets with butter and put in the freezer to get them really cold before you need to pour the brittle. After you pour the candy you should put the pans in the fridge or outside if it is cold, so the brittle will set up quickly and stay fluffy.

Can you use parchment paper when making peanut brittle? ›

You will want the cookie sheet to be non-stick. Use parchment paper, a silicone baking sheet or a greased cookie sheet. Spread the peanut brittle as thin as you can. Immediately add your sea salt.

How long does homemade peanut brittle last? ›

To store: Once it's completely cooled, store peanut brittle in an airtight container at room temperature. Do not refrigerate as the moisture from the fridge will cause the brittle to soften. Store for 6-8 weeks. To Freeze: Peanut brittle can be frozen and stored up to 3 months.

Why is microwaved food chewy? ›

When one of those sugar molecules reaches 212 degrees Fahrenheit, it melts, which softens it. This is why bread can actually feel soft and fluffy when it first comes out of the microwave. But then when it cools, that molecule recrystallizes and hardens, causing the bread to become chewy and hard.

Why does microwave make food chewy? ›

It all boils down to the natural sugars found in flour. Flour, milled from wheat, contains gluten (a type of protein) and sugars (which form starch when their molecules are chained together). When these sugars are heated, they melt and then quickly recrystallize, resulting in an undesirable chewy texture.

Why did my toffee turn out chewy? ›

Low and slow. Simmering the syrup for English toffee to the requisite 300°F temperature can (and should) be a slow process — up to 20 minutes or so. Don't hurry this gradual transformation; syrup that doesn't reach 300°F, or close to it, will make candy with timid flavor and chewy (not crunchy) texture.
