I made this sweet, peanut-packed candy for Christmas and sent some with my husband to work. His co-workers liked it so much they asked for more. It has a lovely glossy look and the cinnamon is a delightful surprise. You've got to try this peanut butter brittle recipe. —Grace Miller, Mansfield, Ohio

  • 1 cup sugar
  • 1/2 cup light corn syrup
  • 2 cups salted peanuts
  • 1 teaspoon butter
  • 1/2 teaspoon ground cinnamon
  • 1 teaspoon baking soda
  • 1 teaspoon vanilla extract


  1. In a 2-qt. microwave-safe bowl, combine sugar and corn syrup. Heat, uncovered, on high for 3 minutes; stir. Heat 2-1/4 minutes longer. Stir in peanuts, butter and cinnamon.
  2. Microwave, uncovered, on high until mixture turns a light amber color (mixture will be very hot), 20-30 seconds. Quickly stir in baking soda and vanilla until light and foamy.
  3. Immediately pour onto a greased baking sheet and spread with a metal spatula. Refrigerate until firm, about 20 minutes; break into small pieces. Store in an airtight container.

Test Kitchen Tips
  • Unless otherwise specified, Taste of Home recipes are tested with lightly salted butter. Unsalted, or sweet, butter is sometimes used to achieve a buttery flavor, such as in shortbread cookies or buttercream frosting. In these recipes, added salt would detract from the buttery taste desired.
  • Cinnamon comes in two basic types: Ceylon and cassia. Ceylon cinnamon’s delicate, complex flavor is ideal for ice creams and simple sauces. The spicy, bolder cassia cinnamon (often labeled simply as cinnamon) is preferred for baking.
