Butterscotch Marshmallow Bars

Butterscotch Marshmallow Bars: chewy delicious and addicting!
Oh. My. Gooey. Goodness. These bars are so sinfully delicious that you should NOT even bother making them unless you are okay with eating the whole pan by yourself.

While watching re-runs of Mad Men.

Drinking a giant glass of milk.

In pajamas.

All Mondays should involve dessert. Just sayin.

    Giiiiirl, you be speakin’ my language! How about we make it even more sinful with an avalanche-style scoop of vanilla ice cream on top? Drizzle on some caramel…

    I’ll stop now.

    Any ideas if I can sub Marshmallow Creme for the mini marshmallows as that’s all I have at hand?

    • posted Aug 5, 2012 at 5:57 pm

      I haven’t tried it, but you can certainly try. I wouldn’t use the same amount as marshmallow though, maybe half? So 1 cup? WOrse case scenario is even gooey’er. Not a bad thing.

    I have made these 3 times in the last two weeks, they usually last 1 day and there are only 3 of us. I have found using self rising flour creates the best outcome. It’s the only flour I had the first time so I took a chance and they come out so much better then with flour and baking powder., consistency wise. Delicious.

    I just made these for my kids and, yum! I’m just curious if they need to be refrigerated safety or is that just a cold vs. room temp preferance? I noticed the last step is refrigerate for 1 hour.
    Thanks for sharing! I’m going to try them with a scoop of vanilla ice cream :)

      I found leaving them out turned them even gooier (is that a word??). You can totally leave them out safety wise :) glad you enjoyed them!
