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.

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.

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.

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.

#1 - Store in an airtight container

It should come as no surprise that storing your peanut brittle in airtight containers is one of the best ways to store peanut brittle. Keeping air out helps maintain your brittle's freshness by minimizing the amount of moisture that might come into contact with your sweet treat.

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.

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.

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.

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.

Should you refrigerate peanut brittle? ›

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.

As the sugar is cooking and begins turning amber in color it accumulates small amounts of acid, and that acid reacts chemically with the alkaline baking soda releasing about a zillion minuscule bubbles of CO₂ that get trapped, making the sugar porous and, well… brittle.

If your peanut brittle is too soft, you didn't cook it long enough. It's important to use a candy thermometer and cook the sugar mixture until it reaches the hard crack stage. Watch it closely…you may be tempted to take it off the stove sooner, but don't!!

However, if you don't have a candy thermometer, it's still possible to make this sweet. All you have to do to find out if your peanut brittle is ready to be removed from the heat is to drop a bit of the syrup into cold water and see if it forms brittle strands. If so, you're ready to finish up your confection.

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.

How long does it take for peanut brittle to harden? This microwave peanut brittle starts to harden almost immediately once you finish cooking it and stirring in the baking soda. It will be completely hardened and ready to break into pieces in just 30 minutes.

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.
