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.

Here’s what you’ll need to make it

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.

Pour onto a parchment lined cookie sheet. Be careful because this stuff is hot and the cookie sheet will get hot pretty quickly. Spread the mixture into an even thickness and allow it to set for at least an hour.

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.

You can continue to do this if you want or you can break the pieces by hand into smaller pieces. Store the brittle in an airtight container with parchment or wax paper between any layers. And, that’s it!

Can I vacuum seal peanut brittle? ›

Does weather affect making peanut brittle? ›

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 baking soda added to peanut brittle? ›

Add baking soda to the mixture.

It's going to foam and the mixture will “grow” as you stir it, doubling in volume. Don't leave out the baking soda. The carbon dioxide that is created when the mixture foams is what gives the brittle its texture.

The soda reacts with the acid to make bubbles, and the syrup foams. When the cooked syrup is poured out and begins to harden, many of the tiny bubbles are trapped before they can escape (another reason the baking soda is added at the end).

What is the purpose of adding baking soda to Duff? ›

In summary, the purpose of adding baking soda to dough is to generate carbon dioxide gas, which causes the dough to rise and become light and fluffy. This is important because it makes the dough easier to work with and results in a better texture and flavor in the final baked product.
