But with this peanut brittle, you need nothing more than a microwave, ingredients and a little care to not over cook or under stir. Sweet and salty, this simple dessert is nothing more than sugar, syrup and peanuts!

Making Peanut Brittle Tips

  1. Making peanut brittle is a candy process and that means big heat. Even though this is a microwave oven, your sugar and corn syrup are gonna get scalding, so take serious care not burn yourself on the bowl or while stirring. Get some oven mittsMicrowave Peanut Brittle Recipe (4)~
  2. Prepping goes a long way (with pretty much all cooking) so to keep your candy from pre-maturely hardening, make sure you have everything measured and ready to go.
  3. Want to gift your microwave peanut brittle? Once complete hard and broken down into smaller bits, I like to gift in mason jarsMicrowave Peanut Brittle Recipe (5)!
  4. Like with all candy making, if you have an issue cleaning out your bowl from hardened candy, just let sit in a bowl of water. The water will break the sugar down, takes about 30 minutes.
  5. Seal in a tight container to keep moisture from getting in and leave in a room temperature environment. Do not refrigerate! If you need to do a double layer, put parchment paperMicrowave Peanut Brittle Recipe (6) in between or the top layer could easily stick to the bottom. It is candy after all.

Scalding Sugar

When working with sugar, even in the microwave, its easy to BURN it.

You will know you burned it if you start smelling burnt! The times in this microwave peanut brittle are based on my microwave, but you may need to shave 30 seconds off if you have a very powerful microwave.

In the pictures below, I made peanut brittle at the full times listed AND redid it with a minute shaved off of the 1st and 2nd microwave times.

You can see the color difference with less time. It also tastes less roasted, but the consistency is the same.

Mixture will change color (cloudy) and bubble with air bubbles, this is fine and normal.

Use a spatula to quickly pour into prepared baking sheet.

NOTE ON SPREADING THE BRITTLE:

You don’t want to pop all the bubbles out of the baking soda, so do your best to rotate the baking sheet back and forth to spread your peanut brittle. You can use a spatula to spread a little if necessarily, but don’t go overboard.

It doesn’t spread like chocolate would.

Let set to harden.

I put in the freezer 15 minutes to harden immediately because I have almost no patience, but you can sit on the counter for an hour and it should harden naturally.

Once hard, use a sharp knife or break with your hands into pieces.

Store in an airtight container on the counter.

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? ›

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.

Can roasting be done in the microwave? ›

A convection microwave can be used to roast a variety of foods, including meats, poultry, vegetables, and even baked goods. It's important to adjust the cooking time and temperature based on the specific food being roasted.

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.

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.

How long does homemade peanut brittle last? ›

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.
