Homemade 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.

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. Also, make sure to add your peanuts once the syrup reaches the soft ball stage (239°F).

Why did my peanut brittle turn out chewy? The likely cause is that the sugar mixture didn't reach the proper hard crack stage temperature. Ensuring it reaches 300˚F is key to getting that classic brittle texture.

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.

Didn't combine ingredients right. Didn't get it hot enough. You have to hit hard crack stage heat or it's not going to harden.

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.

- Heat the brittle in the oven for about 5 to 10 minutes, checking frequently to avoid overcooking. 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.

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.

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.

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.

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.

Because excessive softness in candy results from high relative humidity, cook hard candies, such as nut brittle, to 2 degrees higher than the temperature your recipe calls for. The additional 2 degrees in cooking temperature will compensate for moisture in the air, so your candy will still have the correct texture.

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.

Using buttered metal spatula or 2 forks, gently spread and stretch brittle to thin layer. Allow to cool completely. Break brittle into pieces and store in airtight container.

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.

It's so important because if you cook your brittle much beyond the 300 degree F point, it could burn, and if you don't cook it long enough, the peanut brittle won't set as hard and be more sticky and chewy than crunchy and, well, brittle. Be ready to move quickly once the temperature reaches 300 degrees F.

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.

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.
