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.

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.

Whether it's during the cooking, cooling, or storage process, moisture and humidity can ruin the best batch of brittle in minutes, leaving you with a soggy, sticky mess. This is why eliminating moisture anywhere you can is our top tip on how to store peanut brittle.

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.

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.

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. Peanuts: Of course, you'll need peanuts for this classic treat!

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.

If you do NOT have a thermometer, here's what you do. Take a very small cup of cold water and drop a bit of the mixture in. If it dissolves into the water, it's not ready. Mine took 18 minutes to reach the correct temperature, so around 15 minutes start trying the water test.

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.

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.

So, I Googled Salvaging Undercooked Peanut Brittle and followed Tiffany's helpful instructions to throw the pieces back in the pan, turn the heat up and stir, stir, and stir to a raging boil and wait to pour it in the pan until it reaches 300 degrees.

Place a piece of parchment paper over the hot brittle and use a rolling pin to roll the peanut brittle into a 3/8-inch thick flat layer. Use a sharp chef's knife to partially cut the brittle while it is still warm. Allow it to cool completely before coating it with chocolate.

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.

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.

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 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.

Fudge Didn't Set

If your fudge turned out super sticky, or it didn't set as it cooled, it probably never got hot enough. This mistake is super easy to avoid if you use a candy thermometer and cook the fudge to the temperature specified in the recipe (usually between 234 and 239°F).
