Around our house, holiday season isn’t complete without several batches of classic peanut brittle. Making this homemade gift started when I was a child and now continues with my own family.

Growing up, every year our teachers looked forward to receiving a tin filled with addictive, crunchy peanut brittle candy from us. Since there were six of us, however, they inevitably feigned surprise when they opened our gifts year after year.

Why Homemade Peanut Brittle Makes the Perfect Gift

Turns out Mom was on to something. I’ve learned firsthand why her peanut brittle recipe makes ideal holiday treats for family and friends this time of year.

• It’s economical to make. Make batches and batches of peanut brittle and it still won’t break the bank.

Equipment Needed

Making homemade brittle requires a baking sheet, a saucepan, and a candy thermometer.

1. Candy Thermometer – This is the most paramount equipment when making any homemade candy, such as fudge, toffee, or brittle. Temperatures must be spot on for the recipe to work.

For years I used an inexpensive candy thermometer that clips onto the side of saucepan. This definitely works, recently upped the ante recently and purchased a Thermapen, which measures the temp in two seconds.

2. Saucepan – Ideally use a heavy saucepan to conduct heat evenly and prevent scorching the sugar. I truly believe great cookware makes an immense difference with results. Personally I use the Calphalon Tri-Ply Stainless Steel set, because it’s affordable compared to flashier brands, performs fantastically, and will last a lifetime. I used the 2.5 quart sauce pan for this recipe.

3. Baking Sheets – Although any baking sheet will do because it’s simply used to cool the peanut candy, Nordic Ware baking sheets are rated the best in Cook’s Illustrated, are very affordable, and great for baking.

1. Butter a baking sheet and set aside. Alternatively use parchment paper or a silicone baking mat.
2. In a large heavy saucepan combine sugar, corn syrup, water, and salt over medium heat until sugar is dissolved.
3. Bring to a boil and stir in peanuts. Continue cooking over medium heat, stirring, and checking temperature with a candy thermometer. Cook, stirring constantly, until the mixture reaches exactly 300ºF / 149ºC.
4. Remove from heat. Stir in baking soda and room temperature, softened unsalted butter. Pour onto buttered cookie sheet.
5. Spread hot mixture out in an even layer using a wooden spoon or rubber spatula. As it starts to cool, pull with a fork to stretch out more.
6. Cool completely and break into large pieces.

Why Add Baking Soda?

Although some recipes don’t use baking soda, these have a larger margin of error. The baking soda creates micro air bubbles, making it brittle, light, and airy instead of dense and possibly chewy.

Tips / Tricks and Problems Solved

• When making any candy make sure all the ingredients and equipment are ready to go before starting. Timing is crucial and this will avoid any mishaps.
• Exact temperature is key when making Nut brittle. Make sure your thermometer is properly calibrated (see “Why is my peanut brittle chewy”) and precise.
• Use a bigger saucepan, at least triple the volume of the ingredients. The boiling syrup increases in volume, so there has to be ample room for expansion.
• Do not double or triple the recipe. Make one batch at a time. Luckily the process goes quick!
• Can parchment paper or a silicone mat be used instead of greasing the pan? Yes, but DO NOT USE WAX PAPER, which will melt and stick to the peanut brittle.
• If you prefer more nuts to candy ratio, increase the amount of peanuts up to 1 1/2 cups.

Why Is My Peanut Brittle Chewy / Sticky / Didn’t Harden?

This is a temperature issue. Make sure the candy thermometer reaches exactly 300ºF / 149ºC, which is hard crack stage, before pouring onto baking sheet. See “Equipment Used to Make Peanut Brittle” for my recommended thermometer.

If your peanut brittle is still chewy after it cools, you may be able to save it! First test your thermometer in a saucepan of boiling water for a few minutes. 

It should read 212ºF (100ºC). If not, calibrate accordingly so you know what the “true” 300ºF is on your thermometer.

1. Break up the brittle and place it in a glass, microwave-safe bowl. Heat on HIGH heat 1-2 minutes until soft and semi-melted. Melting it in the microwave first prevents it from burning in the pan before it liquifies and is stirrable.
2. Transfer the semi-melted brittle to a a clean saucepan. Continue heating over medium heat until it reaches the adjusted 300ºF temperature.
3. Immediately remove from the heat and add additional 1/2 teaspoon of baking soda. Pour onto prepared baking sheet and let it cool again. 

Substituting Different Nuts

Wondering if different nuts may be substituted? Yes!

To make nut brittle, any preferred nut will work, such as cashews, almonds, pecans, hazelnuts, or mixed nuts. The nuts should measure 1 – 1 1/2 cups total.
