Chunky Peanut Brittle

Directions

1. Butter the bottom and sides of a 15x10x1-in. pan with 1-1/2 teaspoons of butter. Sprinkle with 1 cup peanut butter chips; set aside.
2. In a heavy saucepan, bring sugar, corn syrup, water and remaining butter to a boil over medium heat, stirring constantly. Cook and stir until butter is melted. Cook, without stirring, until a candy thermometer reads 300° (hard-cracked stage).
3. Remove from the heat; stir in peanuts. Quickly pour onto prepared pan; sprinkle with chocolate chips and remaining peanut butter chips. With a knife, gently swirl softened chips over top of brittle. Cool before breaking into pieces. Store in an airtight container.
