Ingredients
- Dry Roasted Peanuts- Dry Roasted Peanuts are the best for this recipe. They are the perfect balance of salty and nutty!
- Granulated Sugar– The brittle mixture is made of melted granulated sugar which can be perfectly melted in the microwave.
- Light Corn Syrup– A little bit of light corn syrup is added for flavor and texture.
- Salt– A bit of extra salt is good to balance the sweetness.
- Vanilla Extract– Vanilla is added for extra flavor.
- Butter– Butter makes the brittle creamier and more like caramel.
- Baking Soda– A little bit of baking soda is added to make the brittle a bit fluffier. It will still be nice and crunchy!

Original recipe from here.
My peanut brittle came out chewy — did I need to cook longer?
It sounds like you needed to cook it longer!
To Bobbi, sometimes I do mine that way on purpose because i like caramel.
Did not turn out good. Taste tough and chewy. What went wrong? Help please.
My guess is something happened in step four. You may have microwaved it a bit too long and it was overheated. I would keep a close eye on it next time, possibly even reducing the microwave time in each step. Your microwave may be stronger than mine. I have a video attached to this post, the visual may help you as well. Hope this helps!
I followed recipe and my brittle came out perfect, I added a little cayenne pepper to spice it up..yummy
I made this recipe exactly like the directions and watched the last minute to be sure it didn’t burn or overcook, however it turned out too light and not say to break into pieces. I made this recipe and another from the web, which cooked l9nger and it came out darker and not as chewy, so I think I maybe should have cooked it longer, it is no doubt my microwave, but it isn’t old, so I figured it would be hotter. The other recipe turned out perfect and I followed those directions exactly as well.
This recipe turned out great. Mine never got a golden color but regardless it had the perfect texture and taste. Easy to make for Christmas.
