First, set out a large ceramic microwave-safe bowl. Not metal or plastic! Then lay a large piece of parchment paper out on the countertop.

In the bowl, mix the sugar and corn syrup into a thick paste. Microwave on HIGH for 4 minutes.

Stir in the butter and vanilla extract. Microwave again for 1 ½ minutes. At this point, the syrup should be golden in color like honey, not too pale or too golden-brown. If it looks pale, microwave another 1-2 minutes.

Finally, quickly but carefully stir in the baking soda. The mixture should foam up and create bubbles. These bubbles are VERY important for the light airy texture of the brittle. Try not to deflate them.

Recipe Variations

There are SO many fabulous ways to tweak and customize this basic microwave peanut brittle recipe! Here are just a few ideas to get you going:

  • Make the brittle with other nuts. Pecans, cashews, and almonds are all great options! You can even chop up and us a bit of each.
  • Add extra goodies. You can mix in cooked and chopped bacon, pumpkin seeds or pepitas, or chopped pretzel pieces… Or just about any yummy crunchy add-ins you like! Just note that chocolate treats can be tricky to mix in to the hot brittle mixture. A better option to make brittle with chocolate candy pieces is to sprinkle on the goodies after the brittle has been spread on the parchment paper but has not yet gotten a chance to cool.
  • Make this a vegan peanut butter brittle recipe. Simply swap dairy butter for your favorite plant-based spread.
  • Easily double or halve the recipe as you need.

Frequently Asked Questions

Can you make this peanut brittle recipe without corn syrup?

You can make nut brittles with agave syrup or honey. However, these are quite expensive options because of how much you need. You also won’t get the same classic texture or shine.

Why did my peanut brittle not harden?

It’s possible that you did not microwave the syrup mixture until hot enough. The ideal temperature of the brittle syrup is 300 degrees Fahrenheit. If you have a candy thermometer I recommend you check the temp right before you stir in the baking soda.

How long does homemade brittle last?

Nut brittles will keep well for up to 3 weeks stored in an airtight container at room temperature. You can also store it in a sealed container and keep it in the freezer for up to 3 months.

FAQs

Why didn't my homemade peanut brittle 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? ›

Baking soda is also very important at this stage since it reacts to the heat, creating carbon dioxide that aerates the caramel, enabling it to snap when someone bites into it rather than requiring them to gnaw at it until it breaks or pulls apart.

Why did my peanut brittle turned out chewy? ›

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.

How do you keep peanut brittle crispy? ›

Should you refrigerate peanut brittle? 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.

Can you overcook peanut brittle? ›

Use a candy thermometer!

If you overcook the brittle, it could be bitter or burnt. If you undercook it, the brittle won't properly set and the end result will be sticky.

Why do you put water in peanut brittle? ›

The water is there in the first place to help prevent sugar crystals. Steam from the boiling water washes down the sides of the covered pot as the sugar cooks and takes with it, down into the boiling sugar, any crystals that form or are thrown onto the sides of the pot.

Why did my peanut brittle turn white? ›

Peanut brittle turning white, often referred to as "sugaring," is typically the result of crystallization of the sugar in the candy. This crystallization can make the brittle appear white or cloudy rather than having a clear, glass-like consistency.

Can peanut brittle be too hard? ›

Why is it too hard? Using baking soda usually prevents peanut brittle from being too, well, brittle. However, if you cook the candy past the set temperature or overwork the candy once you spread it out onto the cookie sheet, that can cause it to become very hard and difficult to bite through.

Why is peanut brittle bad for you? ›

Outside of that single ingredient, peanut brittle is painfully unhealthy. It contains: sugar, corn syrup, and butter, all of which are unhealthy for your body in different ways. But, peanut brittle becomes terrible for your teeth once all of those ingredients are combined into the final product.

Why does my homemade peanut brittle stick to my teeth? ›

Frequently asked questions. Why does my homemade peanut brittle stick to my teeth? This is because you did not cook it long enough in the microwave. If the texture of the peanut brittle is sticky, and not crunchy, this means that you need to cook the mixture longer, until it reaches 300°F.

Does weather affect making peanut brittle? ›

I've learned that brittle is better when made on a cool, dry day. When I've made the candy on a warmer, humid day, it tends to be a stickier brittle. This is because the brittle takes longer to cool, and it reaches a point where it is no longer evaporating moisture into the air.

Should homemade peanut brittle be refrigerated? ›

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.

Can I freeze homemade peanut brittle? ›

Absolutely! If you want to extend the life of your peanut brittle, you can freeze it. But, make sure it is completely cooled, as moisture is an enemy of peanut brittle. Ensure the brittle pieces are separated by parchment paper to prevent them from sticking together.

What is the best pan for making peanut brittle? ›

Heavy 6 quart Dutch Oven pot. Mine is an old 1970's Club Aluminum. It's perfect! You need a heavy THICK pot so it won't scorch.

Why are my peanuts not getting soft? ›

Dried peanuts will require a longer soaking time before cooking, so leave them to soak for at least 8 hours or overnight. Soaking the peanuts ensures that they will soften more easily when they are cooked, giving them their delicious texture.

What makes brittle hard? ›

What Makes it Brittle? The sugar will be cooked to 300ºF (149ºC)—hard crack stage; which when set up would be hard like a lollipop. But peanut brittle is delicate and you can easily bite into it—how? The secret is in the baking soda.

How long does it take for brittle to harden? ›

Don't try to spread the candy once it's on the baking sheet as it starts hardening almost immediately and spreading it doesn't work well. Let the peanut brittle cool for 30 minutes, then break it into pieces. Store it in an airtight container at room temperature for up to two months.

Is peanut brittle supposed to be hard? ›

Peanut Brittle is a smooth, flat candy (similar to toffee), with peanuts in it, that is cooked on the stovetop and poured onto a sheet pan to cool. Once it cools it's broken into small individual-size pieces of hard candy and lasts at room temperature for several weeks.
