It Only Takes Simple Ingredients And (A Little) Patience

No one has ever accused me of being patient when it comes to getting things done. But I love peanut brittle so much that I was willing to make it the old-fashioned way on the stovetop, and I'm glad I did.

Americans have enjoyed peanut brittle, a simple old-fashioned candy for over a century. It is a classic holiday candy, but it tastes great any time of the year! It is gluten-free and relatively inexpensive to make! To make a batch of peanut brittle, you only need sugar, water, corn syrup, butter, vanilla, baking soda, a pinch of salt, and peanuts!

Why You'll Love This Peanut Brittle Recipe

What saved me from stripping my impatient gears when I realized how long it would take to make peanut brittle is that you only need to stir the mixture occasionally. This relative freedom let me keep an eye on it while I bustled around the kitchen, tidying up.

I even stepped into the adjacent laundry room and folded an overdue load of sheets and towels from the dryer while the brittle merrily cooked between stirrings.

Ingredients you need to make peanut brittle- and you'll need a little water, too.

It was fun to make this peanut brittle, and I enjoyed watching it change as it cooked. It went from a yellowish-white, milky mixture to a golden-amber liquid that smelled absolutely amazing, especially after I added the peanuts!

How To Make This Peanut Brittle Recipe

Combine sugar, water, and corn syrup in a heavy saucepan and cook over medium heat, stirring occasionally, until the mixture boils. This process takes 10 to 12 minutes.

Add the butter and continue cooking. Stir occasionally until the mixture reaches the soft-crack stage, 270-290°F degrees on a candy thermometer. This step can take fifteen minutes. Please do not be tempted to turn up the heat.

Add the peanuts and continue cooking until the mixture reaches the hard-crack stage, between 300 and 310°F. It can take 10 to 12 minutes to reach this temperature.

I am so glad I got a candy thermometer instead of relying on a timer or the old-fashioned cold-water method to track the syrup’s progress. I’m pleased with the Taylor candy and deep fry thermometer I purchased. It is easy to read and clips right on the side of my saucepan, a great value for just $10. I'll use it for years to come!

I could easily keep a close eye on the temperature, and the first batch of peanut brittle I ever made turned out great! Now I need someone to “lead me not into temptation” and take it off my hands, because it is my favorite Christmas treat! Seriously, I could eat a whole batch!!

Remove the pan from the heat and stir in the vanilla, salt, and baking soda. The mixture will be HOT!!

Baking soda gives peanut brittle its light, airy texture and lets it break easily into serving pieces. When you add baking soda to the hot syrup, it releases zillions of tiny air bubbles that get trapped in the candy.

Pour the hot mixture onto a parchment-covered baking sheet immediately. I used a 12-by-16-inch sheet pan. The mixture sets and hardens quickly, so work fast to spread it to the suggested one-quarter-inch thickness.

Allow the candy to cool completely. This process can take 30 minutes or more. As soon as it is cool, break it into bite-size pieces. Please make mine big!

After the candy is completely cool, store it in an airtight container at room temperature. It will stay fresh at room temperature for six weeks, but who are we kidding? It won't ever last that long!

People of all ages adore peanut brittle. The buttery, sweet-salty peanutty crunch is simply irresistible. America’s beloved candy has quite an intriguing history. The legend is that peanut brittle was born in the South, like so many good things to eat, but it came about by happy accident in a kitchen long ago!

Many stories explain how peanut brittle came to be, but one is more believable than the others. Supposedly, a Southern belle set out to make a batch of taffy and, by mistake, grabbed baking soda instead of cream of tartar.

Instead of a stretchy, chewy batch of taffy, she got a hard, brittle blob of candy. She found it quite tasty, but how she added peanuts to the hard lump remains a mystery. It does make a good story, though!
