Chocolate Swirl Bars–A Slice of my Life

Most kids love to cook. Once when I was a Cub Scout den mother, I asked the boys whether they would rather do a science experiment or cook something–cooking won by a landslide.  This recipe for Chocolate Swirl Bars meets the kid-friendly test.  The measurements allow you to work a bit on math if you want.  Relatively few ingredients means it is easy to mix up.  And best of all, they LOVE the action of swirling the chocolate into the peanut butter dough.

Note: If you’re making chocolate swirl bars with grandchildren or a group of kids, be sure to check for peanut allergies before you start. Unfortunately, one of my grandsons and one of my great-grandsons would be unable to eat these.

I know they are popular with kids, because my youngest son started making them when he was in eighth grade.  He liked making the chocolate swirl bars, and turned it into a business.  We discussed the cost of the ingredients, which he had to figure out and then return to me from his earnings.

The inspiration for starting a business could have come from Junior Achievement–a school program that helped kids in high school start their own business.  His older son had quite a company going, supervising a group of kids who made macrame’ plant hangers back when macrame’ was all the rage.

At the time, my husband also acted as an advisor for a J.A. group at another high school.  I still have a spatter guard for a skillet and a hamburger press, both made by teens, as reminders of those projects.

But COOKIES! A much better business, in my humble opinion.

My son baked a batch and took small samples of the cookies door to door in our neighborhood, fed them to the neighbors and took orders for a dozen cookies.  I don’t know how long before his interest flagged, but it may very well have been the beginning of a lasting talent in salesmanship.

Whether you cook them yourself, or find some kids to do the baking, you’ll find that the only problem with these chocolate swirl bars is waiting until they are cool enough to come out of the pan. The smell is heavenly. The taste likewise. Can you eat just one?

Easy to make Peanut Butter- Chocolate Chip Swirl Bars look great and taste as good as they look.


  • 1/2 cup Peanut butter
  • 1/3 cup butter (softened)
  • 3/4 cups brown sugar (tightly packed)
  • 3/4 cups white sugar
  • 2 eggs
  • 2 teaspoons vanilla
  • 1 cup flour
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 10-12 oz chocolate chips


1. Beat well the first four ingredients.
2. Beat in eggs and vanilla.
3. Combine flour, baking powder and salt in separate bowl, then beat into the peanut butter mixture.
4. Spread into greased 9" x 13" pan. Sprinkle chocolate chips on top, as evenly as possible.
5. Bake 5 minutes at 350 degrees. Remove from oven, and draw knife through batter to make marbled effect with chocolate.
6. Return to oven and bake for 30-40 minutes in preheated 350 degree oven, until brown on edges, and almost solid in center. (Will continue to firm up out of oven.)
7. Cool on wire rack for ten minutes, then cut in squares. Put cookies on a cooling rack until completely cool. Freeze or store in airtight container.


You can use either semi-sweet or dark chocolate chips and either smooth or crunchy peanut butter in these delicious cookies.  Kids love to make them and get creative with the marbleing.
