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.

The secret is in the baking soda. 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.

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.

#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.

Water: Water helps the sugar completely dissolve. Salt: A pinch of salt enhances the other flavors. If you opt for salted butter, you can skip this ingredient.

The soda gives a puffy, slightly leavened effect. Which makes the candy crisper and easier to break yet still able to melt in your mouth. Without the soda the candy is harder and has a much different mouth feel.

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.

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.

Also do not stir the pan when the mixture is boiling, as this can cause the sugar to crystallize and give a grainy texture. The boiling sugar should turn a deep amber colour when it reaches the correct stage. Too pale and the candy will not set, too dark and the sugar will have burnt.

Can you pour peanut brittle on parchment paper? ›

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.

Too pale and the candy will not set, too dark and the sugar will have burnt. If you feel the outside edge of the boiling sugar is turning too dark too quickly then you can swirl the pan gently once or twice to even out the boiling sugar mixture but do protect your hands from splashes and again, do not stir.

Why is my peanut brittle too hard? Peanut brittle can end up too hard when the temperature gets too high during the cooking process. With a microwave peanut brittle recipe like this one, you may need to adjust the cooking times based on your microwave.
