Instructions Checklist
  • Coat two 12-by-17-inch baking sheets with vegetable spray.

  • In a heavy 5-quart saucepan with lid, combine sugar, corn syrup, and water. Cover pot, and bring to a boil over high heat, about 5 minutes. Dissolve sugar by carefully swirling pot often over burner. Keeping lid on will prevent sugar crystals from forming; however, should crystals form, wash down sides of pot with a wet pastry brush.

  • Once steam just begins to escape from pot, remove cover and reduce heat to medium. Insert candy thermometer, and continue to boil until temperature reaches 230 degrees (thread stage), about 1 minute.

  • Add peanuts, stirring constantly with a metal spoon until mixture reaches 300 degrees (hard crack stage) and is a rich golden brown, 13 to 18 minutes.

  • Immediately remove from heat, and quickly add butter, vanilla, and baking soda. Stir with a metal spoon until butter melts; mixture will become foamy. Pour half of mixture down center of each pan, spreading evenly with a spatula. Allow to cool for at least 1 hour.

  • Turn brittle out of pan, and snap it into shards.

Cook's Notes

Store in an airtight container for several weeks.

Excellent recipe. I wouldn’t expect anything but perfect from Martha Stewart. This is so much easier to work with than recipes that call for adding nuts at the end!

This is the perfect, classic peanut brittle. I made this to give as gifts this year and my husband kept stealing pieces when I wasn't looking. Don't change a thing about the recipe and it will turn out perfectly.
