S’mores Brownie Bars

By  | 

Mike has a wonderful family. Although I knew it before, I’m seeing up-close and personal just how wonderful they really are. You see, our former house sold and our new house wasn’t quite ready for us to move in. What to do? Show up on your sister-in-law’s doorstep, with child, dog and a bag of belongings. Look pitiful. It worked for us! They let us move in for several weeks.

S'mores Brownie Bars

Well, really it wasn’t quite like that. I’m not sure how pitiful I looked but I do know that Sam smiled his most charming smile and his brown eyes danced at the thought of being at his aunt’s house. Although we are determined not to wear out our welcome, we have been made very comfortable in our temporary quarters.

Easy Brownie Hack Recipe

Sam asked his aunt if we could “borrow” her kitchen for a little bit, all the while practically jumping with excitement. She knew he was up to something! He wanted us to bake something for Auntie Alison as a special thank-you. We already had a stash of Pillsbury™ Cake and Brownie Mixes from our last Walmart run so all we needed was a functional kitchen. (Save on Pillsbury™ before you shop!) The “something” we made was S’mores Brownie Bars. They were a hit.

Prep Time: 1 hour 10 minutes
Cook Time: 1 hour 10 minutes
Calories: 7387kcal


  • 1 box Pillsbury Brownie Mix
  • 2 eggs
  • 2/3 cup oil
  • ¼ cup water
  • 2 ½ cups graham cracker crumbs
  • 2/3 cup of butter
  • ½ cup sugar
  • 40 marshmallows


  • Melt butter and stir in sugar and graham crackers crumbs. Press into the bottom of a 9x13 pan lined with parchment paper. Make sure the parchment paper overlaps so you can easily remove the bars from the pan. (Note: This recipe is doubled to make a thick crust. If you want a thinner graham cracker crust then cut crust ingredients in half.)
  • Freeze for 5-10 minutes until set.
  • In a large bowl, stir together the brownie mix, eggs, oil and water until well mixed. Pour onto graham cracker crust.
  • Bake according to package directions.
  • Remove brownies from oven and immediately layer the top with marshmallows and return to oven for 2-3 minutes. For the last minutes, turn on broiler to brown the marshmallow tops.
  • Allow to cool and carefully move from pan onto a serving tray or cutting board.

The next time you want to express heartfelt thanks—and you don’t have a lot of time—or your own oven—remember to mix up a moment with Pillsbury. They make it easy. And so does a nice sis-in-law.

He has taught her that it's okay to jump first and look later, to wear a dirty shirt to the park and to decide that today is a good day to take a nap in your rubber boots.
