Jack’s Million Dollar Bars

  • Author: Jodi
  • Prep Time: 15 mins
  • Cook Time: 10 mins
  • Total Time: 25 minutes
  • Yield: 20 to 24 bars 1x


Units Scale

Cookie Base:

  • 4 cups old fashioned oats
  • 3/4 cup butter
  • 1/4 cup light corn syrup
  • 1 cup brown sugar
  • 1/4 cup peanut butter
  • 1 teaspoon vanilla


  • 1 package (11 ounces) butterscotch chips
  • 1 package (12 ounces) semisweet chocolate chips, see note
  • 2/3 cup peanut butter
  • 1 1/2 cups salted, dry-roasted peanuts



  1. Preheat oven to 350 degrees. Spray a 9-by-13-inch baking pan with cooking spray.
  2. Measure oats into large mixing bowl. Set aside.
  3. In a saucepan, combine butter, brown sugar, corn syrup, peanut butter and vanilla. Cook over low heat until melted, stirring frequently. Pour mixture over oatmeal and mix until combined.
  4.  Press oatmeal mixture into the prepared pan. Bake for 10 to 12 minutes or until lightly brown on the edges. Cool for 30 minutes.


  1. In a small saucepan, combine butterscotch chips, chocolate chips and peanut butter. Cook over low heat until melted. Stir in peanuts. Spread evenly over base.  Refrigerate for at least 1 hour or until firm enough to cut into squares. 


  1.  One package of chocolate chips has about 2 cups in it. For this recipe I like to mix both milk and semisweet for the topping. I use about 1 1/3 cups milk and 2/3 cup semisweet chocolate chips.  Feel free to use all semisweet or a combination of both milk and semisweet. These bars are fairly sweet, so I wouldn’t suggest using all milk chocolate.
