Why I love this peanut brittle recipe

My mom and I had been planning on making Christmas candy the whole time that I’ve been home. Each day we put it off and did other fun stuff like going shopping. Finally, we buckled down and did it.

We made caramels first, and then we decided we had enough energy left to whip up some peanut brittle. Luckily, peanut brittle was much easier than I had imagined.

How to make peanut brittle

In a small bowl, mix together the baking soda and the salt – set aside. Then heat the sugar, water and corn syrup in a large saucepan over medium-high heat until the sugar is completely melted, and don’t forget the candy thermometer!

Bring the sugar mixture to a boil, and continue boiling until it reaches 265°F (hard ball stage).

Once the temperature reaches hard ball stage, stir in the peanuts.

Keep boiling and stirring frequently until the temperature reaches 305°F (hard crack stage). It should get darker in color as it cooks. Immediately remove the pot from the heat and add the butter, vanilla and baking powder mixture. Stir until combined.

Once the brittle is set, it’s time to break it up. To get more natural looking pieces, simply drop the pan from a few inches above your work surface. It should crack on its own into nice big pieces.

What makes brittle hard? ›

Use a candy thermometer!

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 so thick? ›

Not spreading the mixture thinly enough: If the peanut brittle is too thick (usually because you used too small of a pan), it may not cool and harden properly. Be sure to spread the mixture as thinly as possible in the pan. 4. Humidity: Humidity can affect the hardening process of the peanut brittle.

You will want the cookie sheet to be non-stick. Use parchment paper, a silicone baking sheet or a greased cookie sheet. Spread the peanut brittle as thin as you can. Immediately add your sea salt.
