Marshmallow Peanut Butter Double Chocolate Pillowtop Bars

I was stumped coming up with a name for these bars.  There is so much good stuff in them and I didn’t want to omit any key words from the title.

I almost called these Everything-In-Your-Cupboard-Bars but decided that didn’t have a great ring to it.

White and dark chocolate chips, marshmallow creme, peanut butter, oats, a can of sweetened condensed milk and plenty of vanilla extract.

And oh boy, these are my newest favorite bar.


After baking the sweetened condensed milk. marshmallow creme, and peanut butter solidifies into a semi-firm, frosting-ish layer but it’s not really frosting.

It’s more like a Pillowtop.

Just like with a pillowtop for the bed, that top layer is smooth, soft yet firm, comforting, luxurious.

I would love to take a nap on that pillowtop.

Or sink my teeth into it, which I’ve done plenty of already.

They bottom layer is mixture of melted white chocolate, oats, sweetened condensed milk, and vanilla.  Rich, chewy, dense.

If you like white chocolate or sweetened condensed milk, you’re going to love the bottom layer because these bars are bursting with those two flavors.

I didn’t add any eggs and being that there’s no flour, these make for an easy egg-free and gluten-free dessert.

So as long as you’re not sugar free, I’m thinking you’ll like these.



Marshmallow Peanut Butter Double Chocolate Pillowtop Bars (Gluten Free, Egg Free, with Vegan Option)


2/3 c marshmallow creme

2/3 c peanut butter

1 can (14 oz) sweetened condensed milk, divided

1 tsp vanilla extract + 1 tsp vanilla extract

1 1/4 c white chocolate chips (this is most of a 10 oz bag)

1/4 c butter

1 tsp vanilla extract

2 c whole rolled oats

1/2 c (or more) chocolate chips

Optional: 1/4 c+ of other chips such as white chocolate chips, butterscotch chips, peanut butter chips, toffee bits, sprinkles etc)


1. Preheat oven to 350F and line an 8 x 8 or 9 x9 pan with foil and spray with cooking spray.

2. Place marshmallow creme, peanut butter, half of the 14 ounce can of sweetened condensed milk, and 1 tsp vanilla extract into a medium bowl and mix with a spoon until well combined.  Set aside.  This is the marshmallow/peanut butter layer.

3. Place butter and white chocolate chips into a saucepan and heat over the stove top to melt.  Note that the white chocolate and the butter will melt fast, possibly within 30 seconds.  Take care not to scorch it by taking it off the heat source as soon as it shows signs of melting and just keep stirring it with a spoon to encourage full melting.  After the white chocolate chips and butter have melted, add the remaining half of the 14 ounce can of sweetened condensed milk and 1 tsp vanilla extract.  Stir again.  Add in the oats and stir.  Pour this white chocolate/oats mixture into the prepared baking pan.

4. Add the marshmallow/peanut butter layer over the top of the white chocolate/oats layer.  Gently spread it over the top with a spatula.

5. Lightly layer the chocolate chips (or other/additional chips) over the top.

6. Bake for 20-22 minutes at 350F or until edges begin to pull slightly away or brown a big.  Center may seem somewhat jiggly, but will set up while cools.  Don’t overbake.  You want these gooey.  Allow to cool well before slicing and serving.  Expedite this by placing in the fridge or freezer.


Use certified GF oats if needed rather than conventional oats and read all labels on all other products to check for trace gluten.

To make this vegan, use margarine in place of butter.  Use full fat coconut milk sweetened with agave rather than sweetened condensed milk.  Use vegan white chocolate and vegan marshmallows<– Lots of tweaks, yes, but not impossible.



The recipe I used is very forgiving so if you have most of the ingredients, you’ll be okay.

Most people, or more specifically, most blog readers have oats, peanut butter, and chocolate chips on hand, right?

Thought so.

If you like the sound of today’s bars, I also recommend…

White Chocolate Vanilla Marshmallow Cake Bars.  They are more white-chocolate-meets-cake tasting because I used cake mix as the base layer rather than oats.

And if you want something that’s vegan and gluten free, a bit less sweet, very robust and flavorful because of the pumpkin, I suggest Pumpkin Peanut Butter Oatmeal Bars

Magic 8 Bars also have white and dark chocolate and sweetened condensed milk.  If you’ve never had a Seven Layer bar, try…eight.

Back to the Pillowtop Bars and how good it feels to make teeth marks in them.

You’ll thank me later that you tried these even if it means a little extra time on the treadmill.

They’re worth it.

They’re probably my newest favorite dessert.  The runner up is probably these cookies but you can’t really compare cookies and bars, apples and oranges.


1. Are you a fan of white chocolate, dark chocolate, peanut butter, vanilla, marshmallows?  What makes you say…ahhhh….What’s your current favorite dessert?

2. Ever tried a pillowtop topper for your mattress or have a mattress with a pillowtop that’s attached?

Once I bought a pillowtop layer add-on from Bed Bath & Beyond for a rock hard mattress and it helped tremendously.  It was a much cheaper alternative than buying a new softer mattress for a bed that was in our guest room (when we had a guest room).

There’s a difference between firm and rock-like.  Some firmness is fine, but not too much.  I’d prefer soft and squish to that sleeping on concrete feel.  What about you?

Hope you all had a fabulous Thanksgiving if you celebrate and a great weekend.   Have a great week!

  1. Daaaaaaaaaaaaaaaaaaaaaaaaaaaaaamn. I bet the marshmallow/PB combo is perfect!! They look so smooth and creamy… my mouth is super watering over here!

  2. I need to remember to not come here when I’m hungry! lol Now I want one of each of those bars!

  3. These look amazing… and simple enough for me to try with my students! I teach high school special ed and we are always looking for forgiving recipes to try with them.

    • My mom taught special ed for 30 years. My hat is off to you, my friend.

      I have lots of no-bake desserts in my dessert recipes tab that may be even easier. These are really good but there are a few bowls and steps, not hard by any stretch, but I have other ones too. Whatever you make, you are amazing for cooking with your students :)

  22. LOL – everything in your cupboard would certainly be memorable for a title, thought not exactly as descriptive as pillow top!

  23. I’m trying to use up everything in my cupboard right now so these are quite perfect! I only have a bag of marshmallows though. Can I use marshmallows instead of marshmallow cream? I never buy that stuff & don’t really want to start now. Is there a way to make my own?

    • You could probably melt the marshmallows over the stovetop or gently in the microwave, then stir in the PB and SCMilk. I haven’t tried it that way but it will probably be okay as long as you make sure to not overheat the marshmallows so you can stir in the PB and SCM.

  24. Thanks Averie! I ended up googling it and came up with a ratio of 8-10 large marshmallows to 1tsp white corn syrup will make 1cup mallow creme melted over a double boiler. When I tried it I found it difficult to fully melt the marshmallows so I ended up adding more syrup for a total of approx 1 tbsp, then added the peanut butter and melted it all together till smooth. I let the mixture cool to slightly warmer than room temp and then used it as recipe directed. It didn’t look like a full cup like google findings had said but maybe very rough 1/2c? It seemed to work well in the recipe though as consistency/ thickness was perfect. My peanut/mallow layer looked thicker than your though. I’ve made many of your recipes in the last couple weeks to clear out my pantry and all but one have been a hit at work and with the family! These were chewy and good but I think I prefer blondies, magic cookie bars, classic peanut marshmallow bars though. I never use to find things too sweet but apparently things are changing… this could be good or bad?? Can’t wait to try more of your recipes out!

    • Sounds like you improvised as much as possible and this is one of those recipes that truly is amazing with the ingredients I have access to and wish you could try it that way but sounds like you pulled off something pretty wonderful!
