Butterscotch Bars with Chocolate and Disappearing Marshmallows

Ahhhhh…these, my friends, are a real treat. Straight from my childhood, a pan of this irresistible goodness was a regular at our house. Mom was (and still is) no slouch in the baking department, and these Butterscotch Bars with Chocolate and Disappearing Marshmallows were always a favorite.

Truthfully, I’m not the biggest butterscotch fan, and rarely bake anything butterscotch-y. But every once in awhile I come across a dessert that makes me question why I don’t use the flavor more. I think the key for me is to not have an overwhelming amount of butterscotch. This recipe fits that thought process perfectly.

These bars are rich with a mixture of butterscotch and chocolate, and chewy from marshmallows you’ll never see again after the pan slides into the hot oven. Once baked, the marshmallows scattered throughout the batter melt into their surroundings, leaving little pockets of ooey gooey chewiness. Paired with a glass of cold milk, I think you’ll agree they’re about the most perfect butterscotch bar you’ll ever have the pleasure to meet.

Mom’s recipe was designed for a 9” square pan. But when I couldn’t find my 9” pans (maybe you heard me tweeting for help?!), I doubled all the ingredients and baked it in a 9” x 13” pan instead, which is what I’m sharing here. This recipe is so good, a smaller pan is just not enough anyway! 

And, yes, I did find my pans. After a couple hours of tearing my hair out, and the house apart. They were in our girls’ art cabinet, being used as trays for their stained glass window projects. It was kinda hard to stay angry after that find.

Kinda.  :wink:

Butterscotch Bars with Chocolate and Disappearing Marshmallows

Yield: 16 bars

Ingredients

  • 1 c. butterscotch chips
  • 1/2 c. unsalted butter
  • 1-1/2 c. all-purpose flour
  • 2/3 c. packed brown sugar
  • 2 tsp. baking powder
  • 1/2 tsp. salt
  • 1 tsp. pure vanilla extract
  • 2 large eggs
  • 2-1/2 c. mini marshmallows
  • 2 c. semi sweet chocolate chips

Preparation

Preheat oven to 350°. Spray the bottom and sides of a 9'' x 13'' pan with cooking spray and set aside.

In a large sauce pan over medium low heat, melt the butterscotch chips and butter, stirring constantly. Remove from heat to cool.

In a medium bowl, whisk together the flour, brown sugar, baking powder, and salt.

Add vanilla and eggs to the butterscotch mixture and stir well. Then add the flour mixture and stir to combine. Fold in the marshmallows and chocolate chips, just until combined. Spread into prepared pan and bake for 20 to 25 minutes, taking care to not over bake. (I think they're best when just slightly under-baked!) The edges should be browned nicely, and the center not quite set. The bars will firm upon cooling.

    what is the baking time for an 8-inch square pan? i don’t trust myself with a 9 x 13 of these

      Hi Natalie – For an 8″ pan, half the ingredients. I’m guessing about 20 minutes, but set your timer a little sooner than that to check on the doneness.

    I’m glad you found your missing pans…what a lovely surprise when you did. The girls stained glass work is great.
    Your mom’s recipe is a keeper! Love the *disappearing* marshmallows. Like you, I’m not a big eater /baker of butterscotch recipes. Knowing this has the perfect balance of that flavour has enticed me to give them a try. Betcha I make them more than once ;)

    Usually butterscotch overpowers anything that it’s in, at least for me, but I do love the flavor.

    I like the idea is disappearing marshmallows :) I like when marshmallows are so soft and gooey and then you take a bite of one and it stretches out. That’s the best :)

    This recipe arrived at just the right time for this Kansas farm wife. I was looking to make a bar cookie to take to the guys working on planting the 2013 wheat crop. They are currently cooling on the kitchen counter, and I couldn’t resist trying a corner before it was cool. Yum! Thanks for sharing in time for the guys’ supper!
