Homemade Peanut Brittle (+Video) (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.

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 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.

You'll also want to prepare a baking sheet, with either a silicone mat or parchment paper. The mat/paper will help ensure the peanut brittle doesn't stick directly to pan once it has cooled.

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.

Examples of interfering agents include corn syrup and cream of tartar. A key step in making brittle is heating the syrup to the proper temperature.

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 what's missing — corn syrup. A common brittle ingredient, Asare said, corn syrup causes brittle to go all gooey, gummy and tooth-clingy as it melts in your mouth, whereas sugar crunches, crumbles and dissolves.

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.

How do you fix crumbly peanut brittle? ›

Put it in a pan on low heat and very slowly melt it. Once it begins to melt you can increase the heat a bit. The trick to this is that you have to stir it constantly in order to keep the peanuts from burning. You're going to want to bring it back to 300F, then immediately pour into the prepared pan.

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.

Why Is My Peanut Brittle Chewy / Sticky / Didn't Harden? This is a temperature issue. Make sure the candy reaches exactly 300ºF / 149ºC, which is hard crack stage, before pouring onto baking sheet. See “Equipment Used to Make Peanut Brittle” for my recommended thermometer.

To protect the counter where you will be spreading hot candy, use parchment. It works as well as aluminum foil for the purpose, plus it has a centuries-long clean record.

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.

Give the brittle time to set.

The exact amount of time depends on the temperature and humidity of your home, but plan to let it sit for at least an hour.

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.
