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

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.
