Ingredients for Microwave Peanut Brittle

• Unsalted Peanuts – I personally like unsalted peanuts so I can control the sweet n’ savory level of the peanut brittle. The salt level of salted peanuts can be overwhelming in peanut brittle.
• Vanilla – A little splash of vanilla helps elevate the flavor of this easy microwave peanut brittle.
• Butter – You can use salted or unsalted, both will work great!
• Corn Syrup – This is what makes peanut brittle candy-like. It helps give a smooth texture and sweetens the peanut brittle.
• Sugar – When used this microwave peanut brittle recipe, the sugar caramelizes to create that sweet, crunchy, brittle.
• Baking Soda – Baking soda will help create the little air pockets and bubbles that microwave peanut brittle needs to stay light and crunchy.

How to make Microwave Peanut Brittle

Before making anything, be sure to grease a baking sheet thoroughly with butter. You’ll want this ready to go so you’re not rushing later when you’re ready to spread the microwave peanut brittle mixture out to set.

In your microwave safe glass bowl, mix together the corn syrup, sugar, salt and heat in the microwave for 3.5 minutes.

Stir in your unsalted peanuts and then microwave again until light brown. Then, stir in the butter and vanilla and microwave for another minute and a half.

Add the baking soda and stir it thoroughly and then quickly pour onto your butter baking sheet.

Let the peanut brittle set, and then break into pieces and serve!

How to Store Peanut Brittle

Store your microwave peanut brittle in an airtight container at room temperature. Avoid storing in the fridge because any condensation could make the brittle chewy.

My peanut brittle got stuck to the baking sheet. What do I do?

If you find that your peanut brittle is getting stuck, you could try spreading it onto parchment paper or a buttered slip mat.

Why Is My Peanut Brittle Chewy?

You may end up with chewy peanut brittle if you did not cook the mixture long enough. If your peanut brittle is chewy after being stored, there is most likely excess moisture where you are storing it that has made it chewy.

How long does peanut brittle take to harden?

I like to let my microwave peanut brittle set for about 20-30 minutes before breaking it into pieces.

I love this super simple, crowd favorite, classic. Three cheers for easy peanut brittle that is light and crispy and won’t break your tooth!

Cook ModePrevent your screen from going dark

Instructions

• Butter a rimmed cookie sheet and set aside.
• In a glass bowl stir together sugar, syrup and salt in a glass safe bowl. Microwave for 3.5 minutes.
• Stir in the peanuts and microwave for an additional 3 minutes or until light brown.
• Stir in butter and vanilla and microwave an additional 1.5 minutes.
• Add baking soda and gently stir until light and foamy. Quickly pour mixture onto prepared cookie sheet. Gently rotate the pan to spread mixture until it's a 1/2'' thick.
• Let the peanut brittle cool until it's set. Break the candy into small pieces and store in an airtight container.

Tips

• Have your cookie sheet buttered before you make the peanut brittle because it sets up fast. 
• You can also use parchment paper to pour your brittle onto. 
• Wondering why we use baking soda? Baking soda makes the brittle tender by adding air bubbles, giving it a porous texture.
• To store this candy simply layer the brittle in an air tight container and place parchment or wax paper between the layers. 
• Peanut Brittle will keep in an airtight container for up to two months so it’s a great make ahead candy.
• Switch things up and substitute the peanuts for cashews, walnuts, hazelnuts or pecans.
