Homemade Microwave Peanut Brittle

I had been telling my mom that she needed to get a new microwave since I was a teenager. It took FOREVER to heat things up. I knew it was old and loosing power but she wouldn’t hear it. Needless to say, 10 years later when she finally moved to a new home and tried to make her microwave peanut brittle recipe in her new microwave it burnt! The cook time was far too much in a fully powered microwave. HAHA!

The old microwave happened to be located in our basement yet seeing we are the ones who bought their old house. After her first failed attempt, she immediately requested her old microwave back. She could gladly have it.

Now every Christmas season, my Dad has to haul the old microwave upstairs from the basement storage room just so Mom can make her amazing Microwave Peanut Brittle!

How to Make Peanut Brittle in a Microwave

Needless to say, I had to rework the cook times so it would work in a normal microwave. After a few different tests, I figured it out so it tastes just like my Mom’s peanut brittle and will work in everyone’s normal microwave.

Everything comes together in a glass casserole or mixing bowl. The first step is to stir the corn syrup and granulated sugar together and microwave for 3.5 minutes. Next, stir in peanuts and microwave for 3 more minutes, until light brown. Add the butter and vanilla to mixture and stir until well combined. Microwave for an additional 1.5 minutes.

You will need to work quickly for the next step, so be sure to have your buttered baking sheet already to go. Add the baking soda to the mixture and gently stir until light and foamy. Quickly pour the foamy mixture onto the greased cookie sheet. Do NOT use a spoon to spread the mixture around. Instead, gently rotate the pan to spread the mixture around until it is about 1/2 inch thick.

Let the peanut brittle cool for 1/2 hour. When it is cooled, break the candy into small pieces and store in air-tight container.
