Why this Recipe Works

The Sugar, Water, and Corn Syrup Combo Creates Foolproof Caramel – Corn syrup keeps the sugar from crystallizing, so the brittle cooks into a smooth, glossy, perfectly snappy candy every time – no graininess, no guesswork.

Butter Adds Richness and a Melt in Your Mouth Finish – A small amount of butter softens the caramel just enough to keep the brittle crisp but not tooth breaking.

Simple Ingredients Make Classic Holiday Nostalgia – With just pantry staples and a stovetop, you get a timeless candy that feels homemade, cozy, and perfect for gifting, filling tins, or adding to dessert boards.

Ingredients You’ll Need

2 cups Sugar – Forms the base of the caramel, giving the brittle its sweet flavor and signature golden color.

1/2 cup Water – Helps dissolve the sugar and allows it to cook evenly into a smooth, bubbling syrup.

1 cup Corn Syrup – Prevents crystallization, ensuring the brittle stays glossy, crisp, and perfectly snappy.

2 cups Salted Roasted Peanuts – Adds crunch, saltiness, and that classic peanut brittle flavor. Roasted peanuts deepen the nutty taste.

2 tbsp Butter – Adds richness and helps create a smooth, melt in your mouth caramel texture.

1 1/2 tsp Baking Soda – Creates tiny air bubbles that lighten the brittle, giving it that signature airy crunch.

1 1/2 tsp Vanilla – Adds warmth and depth, rounding out the caramel flavor with cozy sweetness.

How to Make Old Fashioned Peanut Brittle

Line a 15 x 10 x 1 sheet pan with parchment paper. Set aside.

Measure out 2 cups salted roasted peanuts, 2 tbsp butter, 1 1/2 tsp baking soda, and 1 1/2 tsp vanilla and have them ready.

Add 2 cups sugar and 1/2 cup water to a medium sauce pan over medium heat. Stir in 1 cup corn syrup. Cook mixture, stirring occasionally, until it comes to a gentle boil. (Don’t be tempted to turn the heat up!)

Attach a candy thermometer to the edge of the pot, and make sure it is submerged in the liquid, but not touching the bottom of the pot. Cook, stirring occasionally until temperature reaches 250 degrees.

Stir in the peanuts and mix constantly until the candy thermometer reaches 300 degrees.

Remove mixture from the heat and immediately stir in the butter, baking soda, and vanilla. The mixture will foam and change texture.

Carefully pour the hot mixture onto the prepared pan and quickly spread the mixture into an even layer.

Allow to cool completely. Once cool, break apart into pieces.

Use a Heavy Bottomed Sauce Pan – It heats evenly and prevents hot spots, which helps the sugar cook smoothly without burning.

Watch the Color, Not Just the Clock – You’re looking for a deep golden caramel – that’s when the flavor is richest and the brittle sets with the perfect snap.

Spread Thin for the Best Crunch – Pour the hot brittle and gently tilt the pan or use a spatula to create a thin, even layer. Thinner brittle means a cleaner snap.

Don’t Refrigerate to Cool – Let it cool at room temperature so the texture stays crisp and doesn’t become sticky.

Perfect for Gifting – Break into shards and tuck into thins, jars, or cellophane bags – it stays fresh for weeks and looks beautifully homemade.

Store Airtight – Humidity is brittle’s enemy. Keep it in a sealed container to maintain that perfect crunch.
