Stir in the butter and vanilla extract. Microwave again for 1 ½ minutes. At this point, the syrup should be golden in color like honey, not too pale or too golden-brown. If it looks pale, microwave another 1-2 minutes.

Finally, quickly but carefully stir in the baking soda. The mixture should foam up and create bubbles. These bubbles are VERY important for the light airy texture of the brittle. Try not to deflate them.

Recipe Variations

There are SO many fabulous ways to tweak and customize this basic microwave peanut brittle recipe! Here are just a few ideas to get you going:

  • Make the brittle with other nuts. Pecans, cashews, and almonds are all great options! You can even chop up and us a bit of each.
  • Add extra goodies. You can mix in cooked and chopped bacon, pumpkin seeds or pepitas, or chopped pretzel pieces… Or just about any yummy crunchy add-ins you like! Just note that chocolate treats can be tricky to mix in to the hot brittle mixture. A better option to make brittle with chocolate candy pieces is to sprinkle on the goodies after the brittle has been spread on the parchment paper but has not yet gotten a chance to cool.
  • Make this a vegan peanut butter brittle recipe. Simply swap dairy butter for your favorite plant-based spread.
  • Easily double or halve the recipe as you need.

Frequently Asked Questions

Can you make this peanut brittle recipe without corn syrup?

You can make nut brittles with agave syrup or honey. However, these are quite expensive options because of how much you need. You also won’t get the same classic texture or shine.

Why did my peanut brittle not harden?

It’s possible that you did not microwave the syrup mixture until hot enough. The ideal temperature of the brittle syrup is 300 degrees Fahrenheit. If you have a candy thermometer I recommend you check the temp right before you stir in the baking soda.

How long does homemade brittle last?

Nut brittles will keep well for up to 3 weeks stored in an airtight container at room temperature. You can also store it in a sealed container and keep it in the freezer for up to 3 months.
