Easy Microwave Peanut Brittle Recipe (2024)

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.

What does baking soda do for 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.

How do you keep peanut brittle crispy? ›

The candy will attract moisture from the air, making it unpleasantly sticky instead of shatteringly crisp. Once it's completely cool, transfer it to an airtight container.

Why is my peanut brittle too thick? ›

As mentioned in “how to make peanut brittle”, it's very important to move fast after the peanuts and baking soda are mixed in. If not, the peanut brittle will turn out too thick and clumpy. Don't play the guessing game and use a candy thermometer instead. This will ensure your peanut brittle turns out perfectly golden.

How do you make peanut brittle hard again? ›

- Preheat your oven to a low temperature, around 250°F (120°C). - Break the stale peanut brittle into smaller pieces. - Place the brittle pieces on a baking sheet in a single layer. - Heat the brittle in the oven for about 5 to 10 minutes, checking frequently to avoid overcooking.

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.

Why won t my peanut brittle set? ›

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 didn't my peanut brittle set? ›

Why didn't my homemade peanut brittle get hard? Same answer as the question above. If your peanut brittle is not hardening, it's because the sugar mixture did not get hot enough to properly caramelize, cool and become hard, crisp and crunchy.

Can you overcook peanut brittle? ›

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. A thermometer is an accessible and inexpensive way to monitor temperature and ensure properly cooked brittle. Make sure your baking soda is fresh and active.

Why is my peanut brittle hard but sticky? ›

What's important to know is that the corn syrup controls the grain of the brittle so adding too little and you have a grainy textured brittle, while adding too much will result in a stringy and sticky brittle.

Should homemade peanut brittle be refrigerated? ›

To store: Store peanut brittle (once it's completely cooled) 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 my peanut brittle so light in color? ›

If your peanut brittle reached 311°F but is a pale milky color, it's likely the candy cooked too quickly. It reached the correct temperature but didn't cook long enough to undergo sufficient Maillard reactions and develop the characteristic brown color and rich, roasted flavor. Next time, cook at a lower temperature.

Why is my peanut brittle bitter? ›

I don't recommend substituting honey, molasses, or agave for the corn syrup. Those other liquid sugars have impurities that will burn at the higher temperature of making caramel, leading to a bitter-tasting brittle.

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.

Can you pour hot peanut brittle onto parchment paper? ›

You can spread the hot brittle mixture on parchment paper or a silpat liner, but I find the silpat liner a bit safer as it doesn't move around on the sheet pan like parchment has a tendency to. I've been able to keep brittle crisp for up to two months.

Why are my peanuts not getting soft? ›

Dried peanuts may require boiling up to 24 hours until they soften. If your water is hard, full of minerals, or you are boiling at high altitude, then your boiling times for dried peanuts may be greater than 24 hours.

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.

Why did my peanut butter fudge not get hard? ›

The amount of time you cook fudge directly affects its firmness. Too little time and the water won't evaporate, causing the fudge to be soft. Conversely, cook it too long and fudge won't contain enough water, making it hard with a dry, crumbly texture.
