This 10 Minute Peanut Brittle is buttery and crunchy and takes only 10 minutes to make in the microwave.  It’s so delicious and it’s a great candy to make for the holidays.  I make several batches of this easy candy and gift it. But why make it just for the holidays? It’s great anytime!

You can forget making Peanut Brittle the old fashioned way of standing over the stove and using the candy thermometer.  I am the first person to say, that I don’t use a microwave for anything but defrosting, reheating or melting butter or chocolate.  That is except for making this Ten Minute Peanut Brittle.

I stopped cooking peanut brittle over the stove years ago when my sister gave me this easy and delicious recipe for Peanut Brittle.  I will never go back.  I make several batches of this at Christmas to give as gifts.  This is the easiest candy recipe you will ever make.  I promise!

Easy steps for this easy peanut brittle

Start by combining some sugar, salt and corn syrup in a large bowl and microwave it for exactly 5 minutes.  The bowl will be hot so be careful…

Add some raw Spanish peanuts. Using a heatproof spatula, mix the peanuts into the sugar mixture, making sure to cover all the peanut with the wet mixture. Microwave for exactly 2 minutes.

Remove the bowl from the microwave. Again, be careful, it will be very hot. Using a spatula, stir the mixture for about 30 seconds, giving the peanuts time to slightly brown. It won’t be much of a change. Now microwave for 1 additional minute.

Remove the bowl from the oven, add some butter and vanilla and mix to incorporate.

Sprinkle some baking soda over the mixture.

Now mix the baking soda in and allow the baking soda to perform its magic.  See how it magically makes the candy foam up? This is what makes the Peanut Brittle light and airy…

Immediately scoop the mixture onto a baking sheet covered with a piece of parchment paper. Spread it out quickly with the spatula.

Place the peanut brittle in a freezer for about 10 minutes to completely cool before trying to break into pieces. In the winter, I place mine outside on my deck. Once the candy is cooled, place it in a 1 gallon freezer, use the handle of a butter knife and break it into pieces.

Note:  The times I used were based on an 1800 watt microwave.  If yours is lower, your candy might take 1 or even 2 minutes longer based on the wattage.  I recommend doing one test batch first. 

Tip

The hardest thing about making this candy is cleaning the bowl. You can soak the bowl with hot tap water, but it will take quite a long time to soak and clean it. Here’s my easy tip. Before you start making this candy, bring a pan of water to a boil and set aside. As soon as the candy is done and you transfer it from the bowl, place the bowl in a sink and fill it with the extremely hot water. After 10 minutes, you can easily clean the bowl.
