You’re gonna need to stop what you are doing right now and make these.

Sorry, it’s true.

I mean, finish reading this post, THEN go make them…first things first.

And I might tell you I am currently on a diet. Which is annoying.

I am sure there are some of you out there who don’t have to diet and just burn off the all the calories by chasing your kids around yada yada.

Well, that’s not me.

I am constantly dieting. Except the past 6 months where I was consciously NOT dieting. In fact I was doing just the opposite…

So yeah, I am dieting and trying to write a blog about sweet, delicious treats that contain gooey marshmallows and white chocolate.

I am pretty sure I deserve a medal or something.

 

So yes, I tried these, almost died at how good they are and then promptly got them out of my house ASAP. Because I start acting shady around desserts.

Like I sneak a bite here and there until there is nothing left in the pan.

Like a thief.

When actually the only person I am stealing from is myself…which makes no sense…or does it make ALL the sense? Dr. Phil, can you HEAR ME?!

Anyhow, I strongly suggest you make these Marshmallow blondies because they are so good your diet can take a break for a bite. Mine did.

How to Make Marshmallow Blondies

I loaded the batter for these up with some butterscotch chips. Now before you decide butterscotch isn’t for you, hear me out.

I don’t like butterscotch chips. Sue me. I feel like the flavor is too strong or something. Anyhow, melt them down with some butter and mix them into blondies and you get a delicious batter that no one can top. I swear.

Of course add a pinch of salt. Or two.

Then mix up your batter. No mixer necessary.

Now, add those marshmallows. They melt right into the batter when baked and create a flaky, crispy top to the blondies, but add gooey pockets throughout. Even my husband who claims he doesn’t like marshmallows loved these.

Mix your batter up with some white chocolate too. Because…

Spread it into a foil lined pan.

And bake them until the tops are just set and they are crackly golden perfection…

And cut them when they’re cooled. Of course!

    Update: After letting them sit for 35 mins, I put them in the fridge for another 35 mins. They don’t look exactly like the picture, but they can be cut into squares! My husband can’t stop eating them! So yummy!

  2. Vanessa

    Poop! Mine didn’t set up either! Followed it exactly, put them back in the oven for even 10 mins longer and they are a runny, but delicious mess.

  3. Cheryl

    Just made these for the first time and they turned out perfect. I did not alter the recipe at all and used an 11 x 7 pan.

  4. Liz

    Made these yesterday and they set up just fine! I baked them for 25 minutes and while they are slightly sticky, they cut into bars perfectly. Thanks for a great recipe!

  5. I also tried this recipe today. …as the majority of the comments mine did not set up either, my batter & everything looked just like the pictures had nice brown crackling top. They did have a wonderful taste but gooey enough to roll into balls. I might try baking with out the foil, I typically do not bake using foil on the bottom. Thanks! !!

  6. Oh dear, I’m afraid mine are not setting either! I currently have them in the oven and they have already been baking for 45 minutes and are still very gooey. I doubled the quantity and put them in an 11 x 7 so perhaps they are a bit to thick. I’ve covered the top with aluminium foil and will keep baking until they are set. I’m determined!! Lol!

    I made these for dessert for Superbowl supper. I let them bake A LOT longer, and they were wonderful! We ate them while they were still a little warm and they were gooey, as you would expect because they were warm. However, they were “set” enough. After they cool, they are perfectly “set”.

  8. Mayagodez

    As I read through the comments on here I was a bit leery to make this because so many people had said that it didn’t set. The recipe looked so delicious I couldn’t resist. I made it and lo and behold….IT DIDN”T SET!! A gooey mess….tasty but still gooey enough that you had to have a spoon. Something is way off on this recipe for this many people to have the same issue.

  9. Baker

    I just made these for a party and quadrupled the recipe and made in a 11 by 17 bar pan. They came out excellent. When baking bar cookies, I always use a heavy duty ceramic pan and it seems to help with texture.

    Unfortunately, I experienced the same problem as some of these other readers. First, I doubled the recipe and tried it with gluten free flour. It was a DISASTER–like soup. “Hmmmm…” I thought “probably my fault for changing the recipe so much.” I tried the recipe again exactly as the directions say and still they did not set. I cooked them 20-25 minutes and waited until they were cooled to cut them and still no luck! Darn it.

    1. Shelly

      Sorry about your experience.. all ovens are a bit different, so the bake time might vary from person to person. The recipe says bake 20 minutes or until center is set, so I would maybe just suggest to continue baking them until they set up.. even if you have to add on a bit of time.

  11. Ellen

    Made these yesterday and they are IRRESISTABLE!! So glad tomorrow is Monday so that I can unload them on my coworkers. For those of you that couldn’t get them to set up-I actually baked them about 25 minutes in an 11×7-perhaps the fact that it was a thinner blondie made them easier to set?

    Next time, I think I may omit the white chips, add a little more salt, and do more marshmallows? This is a recipe I want to play with!

    YOU ARE SO ON MY ZIPLIST LADY!! 😀 which means I’ve got a TON of your recipes saved in that list. 😀 Thanks for everything you post. 😀

  13. Valentina

    Hi! They look amazing.
    You know if there’s any substitute for the butterscotch chips or any recipe to make them from scratch?
    Sadly, i can’t get them here in my country 🙁
    Thanks.

  14. Amanda

    I had the same problem with them not setting up. Flavor is delicious but they are gooey blobs you have to eat with a spoon. I will try again but super sad because we were going to take them to a father’s day barbeque. I cooked them 20 minutes, edges were crispy and top was set.

    1. Mayagodez

      Same here Amanda. Crispy edges and the top was set. We waited until it was completely cooled which wasn’t easy considering 4 boys were anxiously waiting for dessert. It’s too bad because the flavor is great.

  15. Shannon

    I also love all things marshmallow (going to read your S’mores recipe collection in a minute), but had never made Blondies so definitely wanted to try these. I loved how quick and easy they were to prepare. Unfortunately mine took a little longer to set and then I got distracted and ended up overcooking them a little, but they were still fantastic! I can just imagine how much better they’ll taste when I pay attention 🙂

  16. Danielle

    I made these yesterday and omg! I’m trying not to eat the whole pan since I am also trying to eat healthier but boy is it hard to do! I’m usually not a butterscotch fan either but the flavored blend really well!

  17. Alyssa

    I’m dyyyyingggg… okay, I have to make these at my first available excuse! I’m thinking Memorial Day picnics…. omnomnom. Oh but I want them now.

  18. These look incredible! Totally worth breaking the diet for! I know what you mean though, it’s so hard to bake delicious treats for the blog and only have a sliver or a pinch, so not fair! But like you said then I’m only cheating myself if I don’t get them out of the house! 😉

  19. OMG, these were amazing.. I saw this recipe, I knew my family would love them and I had everything on hand… Super easy to whip up…. I subbed out all purpose flour for GF flour and they enjoyed a delicious dessert! Thank you!

  20. Mara

    Sadly these did not ‘set’, I questioned the amount of flour being too little….
    They taste amazing, but…..need some tweaking, IMO.
    I am an experienced baker and followed recipe to a ‘t’.

    1. Shelly

      That’s so strange… how long did you bake them? I have made these a number of times and never had any issue. Did you allow them to cool completely before cutting?

      1. Mara

        Thanks for the reply 🙂
        I cooked them for 20 min. Yes, they were cooled.
        Do you have any tips to make them more of a brownie consistency? You can’t pick it up, and my daughter loves them and wants to bring them to school for her birthday.
        Thanks for you’re time….

  21. I sneak eating desserts all day long. The strange thing about it is….I’m the only one home. I’m only lying to myself….pathetic.
    I love the crackly top! I’m loving the flavor combo in these buttery looking bars!

  22. Those look AMAZING! So so good, I can see why you had to get them out of the house pronto. I also struggle with having two much sweets on hand, but its so hard when baking is your passion! Ah well, all things in moderation…

  23. The combo of marshmallows, butterscotch and dense rich buttery bars is awesome. I’ve done some sort of like this but with PB, too. Defi not diet food. LOL Good for you for doing your best around all your treats. And re-homing desserts is almost mandatory when you bake 5+ days a week like we do! pinned
