What is Peanut Brittle?

Peanut Brittle has been around for as long as anyone can remember but its exact origin is unknown. Brittle is essentially hard caramel candy embedded with peanuts, almonds, pecans, or any nuts of your choice. It is the perfect balance of sweet and salty.

It gets the name brittle because the candy itself is very brittle. It is made in a sheet and easily broken into pieces. The candy is made to break from the air pockets created by baking soda.

This delicious treat is sometimes called Christmas candy because it makes a wonderful gift for the holidays.

Microwave Peanut Brittle Ingredients

You only need 6 simple ingredients for this easy microwave peanut brittle. All of which you should have already, so you should be good to go! However, just in case, here’s a list:

  • Sugar
  • Light corn syrup
  • Vanilla extract
  • Peanuts or your favorite nuts
  • Butter
  • Baking soda

Why Does Peanut Brittle Have Baking Soda and What Does it Do?

Baking soda is actually very important to create the perfect peanut brittle. The baking soda is what creates the bubbly, carbon effect that gives the brittle the best crunch and crack.

You can make brittle without it, but you will find it difficult to get the right consistency. You need baking soda to get airy brittle that cracks easily and prevents it from becoming too hard.

What Do You Need to Make Peanut Brittle?

Surprisingly enough, you will not need a candy thermometer for this recipe. Here’s the equipment you’ll need:

  • Measuring cups and spoons
  • Microwave safe bowl
  • Spatula
  • Nonstick cooking spray
  • Cookie sheet

That is it! Nothing too crazy, just ordinary kitchen supplies.

How to Make Peanut Brittle in a Microwave

Making peanut brittle can be a family tradition. It’s the perfect treat for any time of year. This quick and easy microwave peanut brittle recipe proves candy making doesn’t have to be difficult.

  1. In a microwave-safe bowl, combine sugar and corn syrup until all of the sugar is wet. Microwave on high for 4 minutes.

Recipe Notes and Substitutions

The name of the game is quickness for this recipe. You need to move fast with all of the steps so the brittle doesn’t harden before you spread it out on the baking sheet.

You can substitute coconut sugar for the sugar.

Want to make peanut brittle without corn syrup? You can substitute it with golden syrup or maple syrup.

Why Would Peanut Brittle Not Harden?

If you are finding that your brittle is not hardening properly, chances are that the peanut brittle mixture did not heat up enough to reach the hard-crack stage.

Once it reaches the hard-crack stage, brittle will be drier and less sticky allowing it to harden properly.

Why Did My Brittle Turn Out Chewy?

This will again go back to the heating process. If the brittle was not heated up enough to reach the hard-crack stage, when the brittle cools down it will still be soft, sticky, and chewy.

While the flavor might still be good, brittle should not be chewy. It should have a nice hard crisp when it is broken. So when you are making brittle, be sure the consistency is more dry and stringy before you cool it down.

How to Store Peanut Brittle

Wondering how do you store peanut brittle? It’s simple:

After you are done cooking and breaking up the peanut brittle, store the pieces in a glass or plastic airtight container. Then place the container in a cool dark area for the best results.

How Long Does Peanut Brittle Last?

One of the really nice things about this amazing peanut brittle recipe is the longevity of the brittle. As long as you store it properly, this brittle can last up to two months. It will be just as good as when it was freshly made.

You should store it in a completely dry, air-tight container. Any plastic container or glass jar with a lid will work great. You can even store it in a zip-top bag as long as it closes.

I think that is why brittle is popular to make around the holidays. You can make it ahead of time and give it as a gift and it will last a while.
