This is a classic, old-fashioned peanut brittle recipe that is both quick and easy – no candy thermometer required. Great for Christmas gifts or adding some pizzazz to those cookie trays!

Three pieces of peanut brittle stacked on a piece of parchment paper.

Peanut brittle always fell into the category of “something to buy, not to make” for me. I didn’t grow up in a candy-making family, so tackling things like fudge and brittle was a little daunting to me when I began baking. While I always LOVED to eat peanut brittle, it took me quite a long time before I made it myself.

After all of that intimidation, I was surprised and relieved to find out how simply it came together, and how utterly DELICIOUS it was! I think the first time I made it I actually had to hide the tin from myself so I wouldn’t eat it all. If you’ve been on the fence about making homemade peanut brittle, it’s time to dip that toe in the water and whip up a batch!

How to Make Homemade Peanut Brittle

Homemade candy can be super intimidating, but I’m here to tell you that you have nothing to fear! This peanut brittle is simple to make; your family and friends will be so impressed when you show up with an overflowing tin at the holiday party. Here’s how we do it (only a few steps!):

  1. Make the Caramel – Boil together sugar, water, corn syrup, and salt and cook over medium-high heat until the mixture is a deep golden color; this will take about 20 to 25 minutes.
  2. Add Peanuts, Butter & Baking Soda – You will add these all at once and the baking soda will cause the mixture to foam up (that’s what gives brittle all of those teeny tiny bubbles and that glass-shattering consistency). Continue stirring until the mixture is smooth and no longer bubbling, only about another minute.
  3. Spread the Brittle – You will need to quickly spread the mixture onto your prepared pan into as thin a layer as possible. It will start to harden very fast, so spread, spread, spread that brittle!
  4. Cool Completely – The brittle will take only about 15 minutes to firm up and cool completely, and at that point you can break it up and store it (or eat it!).

Peanut Brittle Recipe Tips

A few quick tips for making sure your peanut brittle making goes off without a hitch!

  • Grease EVERYTHING! Before you begin this recipe, make sure that if you’re not using a silicone baking mat (so perfect for candy!) that you spray your parchment paper with non-stick cooking spray, as well as the spatula you are going to use to spread the hot brittle. The hot caramel will be sticky, and having everything greased will allow you to work faster and get the brittle spread into a thin, even layer.
  • Prep the Ingredients – Have the peanuts, butter, and baking soda measured out and ready to go before you start the caramel. You’ll need to add it all at once as soon as the caramel is ready and you don’t want to have to pause to do any measuring.
  • Work QUICKLY! As soon as it’s ready, you’ll need to pour and spread the brittle onto the prepared pan very quickly. This is key to getting that thin “brittle” consistency; you don’t want to be left with thick brittle!
  • You can use unsalted peanuts, salted peanuts, roasted peanuts, dry roasted peanuts, or raw peanuts in this recipe. Since we are adding the peanuts at the very end off the heat, roasted peanuts will not burn.

The texture of this peanut brittle is spot-on to what I have considered awesome peanut brittle in the past. Plus, there are a boat load of peanuts in this batch, which is music to any peanut-lover’s ears.

To wrap things up, MAKE THIS! It’s easy, you don’t need any special equipment, and it’s one of the best edible gifts to share for the holidays – it lasts for about a month and stays perfectly at room temperature; no special storage necessary!
