Peanut Butter Saltine Brittle

1/2 cup butter
3/4 cup creamy peanut butter
1 cup granulated sugar
1 sleeve (4 ounces) regular saltine crackers
2 cups milk chocolate chips
1/2 cup peanut butter chips
1/2 cup roughly chopped, dry-roasted, salted peanuts

Heat oven to 400 degrees. Line 10-by-15-by-1-inch pan with aluminum foil. Spray foil with butter-flavored nonstick cooking spray; set aside.

Put butter, peanut butter and sugar in heavy-duty, 1-quart saucepan over medium heat. Stir constantly until butter and sugar are melted; bring ingredients just to a boil. Boil mixture 3 minutes, stirring frequently.

While mixture cooks, lay saltines in single layer on prepared pan.

Pour cooked mixture evenly over saltines. Place in oven and cook 5 minutes. Remove from oven and sprinkle chocolate chips over top. Let cool for 3 minutes, then spread chocolate completely over top of saltines.

Sprinkle peanut butter chips evenly over top of chocolate. Return pan to oven for 1 minute to soften chips. Pulling tines of a fork through softened chips, partially cover chocolate. Sprinkle peanuts over top and gently press peanuts down.

Let cool on rack for about 15 minutes, then place in freezer for 3 minutes. Remove from freezer and break into pieces. Store in airtight container.
