  • 1 1/4 lb. raw Spanish peanuts
  • 1 Tbsp. vanilla
  • 1 rounded tsp. baking soda
  • 1 c. white Karo syrup
  • 1 Tbsp. butter

  4. Fold in baking soda and pour onto three buttered cookie sheets.

Tips & Substitutions

To ensure even cooking, stir the mixture frequently while boiling. If you prefer a different nut, almonds or cashews can be great substitutes for peanuts. Always use a candy thermometer to check the temperature; the mixture should reach the hard crack stage, around 300°F. For a twist, consider adding a pinch of sea salt at the end to enhance the sweetness.

Serving Suggestions

Peanut brittle makes a delightful snack on its own or can be served alongside coffee or tea for a cozy treat. You can also chop it up and use it to top desserts like ice cream or brownies, or even incorporate it into recipes like Christmas Amber Rum Cake for added crunch.

Storage & Reheating

Store leftover peanut brittle in an airtight container at room temperature for up to two weeks. If it becomes sticky, you can re-crisp it in the oven at a low temperature, around 200°F, for a few minutes. Make sure to separate pieces to prevent them from sticking together.

Frequently Asked Questions

Can I use roasted peanuts instead of raw?

Yes, you can use roasted peanuts, but be cautious as they will brown faster. If using roasted peanuts, reduce the boiling time slightly to avoid overcooking them.

What can I do if my peanut brittle is too soft?

If your brittle is too soft, it may not have reached the correct temperature. To fix this, you can reheat the mixture slowly, stirring until it reaches 300°F. Be careful not to burn it.

Is there a way to make the brittle more flavorful?

Absolutely! You can enhance the flavor by adding spices like cinnamon or nutmeg, or even a splash of bourbon for a unique twist. Just incorporate these ingredients after removing the mixture from the heat.
