Ingredients

  • 1 cup sugar
  • 1/2 cup light corn syrup
  • 1/8 teaspoon salt
  • 1 to 1 1/2 cups salted peanuts
  • 1 tablespoon butter
  • 1 teaspoon baking soda

Instructions

  1. Combine sugar, corn syrup, and salt in a 2-quart mixing bowl. Microwave on High for 5 minutes.
  2. Stir in salted peanuts.
  3. Microwave for an additional 2 to 5 minutes, stirring after the 2nd and 4th minute until the syrup and peanuts are lightly browned.
  4. Stir in butter, vanilla, and baking soda until the mixture is light and foamy.
  5. Spread the mixture to a 1/4-inch thickness on a large, well-buttered cookie sheet (work quickly).
  6. Allow to cool, then break apart into pieces.
  7. For very thin peanut brittle, cool on the cookie sheet for 3 to 5 minutes, then lift from the sheet and pull or stretch the mixture to the desired thinness.

Tips & Substitutions

For best results, ensure your mixing bowl is large enough to accommodate the mixture expanding while cooking. You can substitute light corn syrup with golden syrup or honey, although the flavor may slightly vary. If you prefer a nut-free version, you can use sunflower seeds instead of peanuts. Be cautious with the microwave timing to prevent burning the sugar.

Serving Suggestions

Peanut brittle makes a delightful snack on its own, but you can also pair it with a scoop of vanilla ice cream for an indulgent dessert. For an exciting twist, consider serving it alongside Grilled P B & J for a nostalgic flavor combination. This treat can also be crumbled over yogurt or used as a topping for desserts.

Storage & Reheating

Store any leftover peanut brittle in an airtight container at room temperature. Avoid refrigerating, as moisture can make it sticky. If it does become soft, you can re-crisp it in a low oven for a few minutes. This treat is perfect for sharing or enjoying alongside a cup of coffee or tea.

Frequently Asked Questions

Can I use unsalted peanuts instead of salted?

Yes, you can use unsalted peanuts if you prefer less salt. Just keep in mind that the overall flavor will be slightly different. You may want to add a pinch more salt to the mixture to enhance the taste.

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

If your peanut brittle turns out too hard, try microwaving it for a few seconds to soften it slightly before breaking it into pieces. Alternatively, you can store it in a warm, humid area for a short time to help it become less brittle.

How can I make this recipe vegan?

To make this recipe vegan, simply substitute the butter with a plant-based alternative, such as coconut oil or vegan butter. Ensure that the peanuts you use are also free from any animal-derived ingredients.
