Cake Batter Marshmallows

Cake Batter Marshmallows | Cookies and Cups

These Cake Batter Marshmallows are simple to whip up! I used mine for Cake Batter S’mores!

Homemade marshmallows.




I know people have been saying it forever, but really, they are so amazingly amazing.

Worlds better than store-bought.

Actually, it’s hard  to even compare them, because they are completely different.


So anyway, I busted out Shauna’s book Marshmallow Madness again.

I am, and have been obsessed with this book for the past year.


Most recently I made these S’mores Fudge Bars using her recipe for Homemade Fluff.  You guys need to make those before the summer ends.  Honestly.


But I decided I needed to make some Cake Batter Marshmallows.  Because I also decided I needed to make a Cake Batter S’mores.  We’ll get to those in a minute.


Of course I knew Shauna probably did all the leg work for the marshmallows already, so I studiously consulted the book.

Yep. She did.


She calls them Birthday Cake Marshmallows.  Tomato-patahto.

Cake Batter Marshmallows | Cookies and CupsThese marshmallows are so fun.  They are a basic vanilla marshmallow, but I added dry cake mix into the mallow AND extra sprinkles.

I even took it one step further and added some cake mix into the coating.

It all worked.


There’s a few steps to these, but if I can so it, do can you.  Pinky promise.


First you’ll need unflavored gelatin…

 photo IMG_2854_zps48e89a55.jpgLet it sit for 5 minutes or so.  It will get jello-ish… It’s called “blooming”.

 photo IMG_2855_zpse52d4995.jpgMeanwhile mix together some sugar syrup in a small saucepan.  Bring it to 240°.

While that is boiling, melt your gelatin in the microwave for 30 seconds and turn it back to a liquid.


Pour that into the bowl of your stand mixer with some corn syrup and let your mixer stir it together on low speed while you’re syrup is boiling.

It will look like the picture in the upper right-hand corner.

Then turn mixer up again and let it mix for another 5 minutes.   It will look like the picture in the LOWER right-hand corner.

Then sift some dry cake mix into the mallow…

 photo IMG_2889_zps8981b027.jpgLet it sit for 6 hours.  I know it’s hard.


Then whisk together some powdered sugar, cornstarch and a little more cake mix. This is your coating.

 photo IMG_2948_zps20fc6cf7.jpgCoat them pretty thoroughly with the coating you prepared…

 photo IMG_2954_zpsf6eaccfa.jpgI seriously love these things.

Cake Batter Marshmallows
makes 24 marshmallows
  • 4½ tsp unflavored gelatin
  • ½ cup cold water
  • ¾ cup granulated sugar
  • ½ cup light corn syrup, divided
  • ¼ cup water
  • ¼ tsp salt
  • ¼ cup white cake mix
  • 3 Tbsp rainbow sprinkles, plus more for garnish
Coating ½ cup powdered sugar
  • ⅓ cup cornstarch
  • 2 Tbsp white cake mix
  1. Line an 8x8 pan with foil and spray lightly. Set aside.
  2. In a small bowl combine ½ cup water and the gelatin. Whisk together and let sit for 5 minutes.
  3. Meanwhile combine the sugar, ¼ cup of the corn syrup, ¼ cup water and salt in a small saucepan over high heat. Boil until the temperature reads 240° on a candy thermometer.
  4. While syrup is boiling pour remaining corn syrup in the bowl of your stand mixer, fitted with whisk attachment. Place the gelatin, which will now be fairly solid in to the microwave and heat for 30 seconds, turning it back into a liquid. Pour that into the mixing bowl with the corn syrup and turn mixer on low and let it run.
  5. When the syrup is 240* slowly pour it in to the running mixer and turn speed up to medium. Beat it for 5 minutes. THEN increase speed to medium high and continue beating for another 5 minutes. Lastly turn mixer up to high and beat for 1 minute more. It will be opaque and fluffy.
  6. Sift in cake mix and fold sprinkles in, until evenly combined.
  7. Pour mixture into prepared pan, garnish with more sprinkles and and let sit in a cool, dry place for at least 6 hours.
  8. When ready to cut the marshmallows, make the coating by whisking together the powdered sugar, cornstarch and cake mix together.
  9. Remove the foil from the pan and peel back from the marshmallow.
  10. Dip your knife into the coating mixture and cut the marshmallows into squares.
  11. Coat each cut marshmallow with coating, to prevent sticking.
Store in a cool, dry place in single layer inside an airtight container fro up to 2 weeks. You will need to toss these again with more coating the longer they sit.

Cake batter marshmallows are the next up on my list of marshmallows I want to make! I bet they would be good in white hot chocolate


Girlfriend! These look spectacular. Adding more mix to the coating? INSPIRED! Love it all. xo

Think of all the desserts you can make with these! these are telling me to make them in to a triple cake batter stuffed cookie. You are a mad genius!

Angelyn @ Everyday Desserts

Ummm …. I really need that cake batter s’more in my life right now.


Can you believe I’ve never made marshmallows?! I need to fix that! I would probably eat the whole pan, but who cares, it’s cheaper than therapy!


Maybe I’ll make a batch of these for the next time I go to the.boy’s parents so we can have FUN s’mores instead of plain ones.

Nancy P.@thebittersideofsweet

I have never made marshmallows. I have attempted and failed miserably but that was before I got my Kitchenaid. Think it is time to try again!!


Homemade marshmallows are truly the best and I LOVE you cake batter ones. So fun!!

I’ve been seriously wanting to make homemade marshmallows for a few years and I finally made them this past week. I wanted to make an all-honey version, but I was making them at my mom’s and she has the most limited kitchen possible! I didn’t have a candy thermometer so I tried to guesstimate soft ball stage and I don’t think I let the syrup cook enough because when I tried to cut the marshmallows, they disintegrated into nothing! I’ll have to try them again now that I’m back in my well-stocked kitchen 🙂

So close! These sound like real diet-killers!

Ashley @ Wishes and Dishes

I agree – this might be your best invention ever 🙂 YUMMMMM!!!

Chung-Ah | Damn Delicious

Oh man I could have a bucket of these marshmallows for lunch!


These super fun marshmallows look so Fruity Pebble like! Super, suppppeeeerrr, cute!!

Melissa @ Treats With a Twist

Oh my gosh!! I LOVE homemade marshmallows! I love making them as gifts. But I have to try cake batter ones! These look amazing! And I just love Shauna. She’s brilliant!

Last year, “pinspired” by the devil’s playground aka Pinterest, I attempted homemade marshmallows. The kids were so excited, I was so excited, it was a joyous occasion. Until it wasn’t, because I failed miserably. I can bake, cook and follow directions like nobody’s business so I have no idea what went wrong but it did, very wrong and all our marshmallow hopes and dreams were crushed, er, flattened. But this recipe, just might be the ticket to helping me recover from my Post Traumatic Marshmallow Experience. You PROMISE that it’s easy?!? 🙂


Gorgeous!! I want some!!

I had some cake mix left over from the Grown-Up Cake Batter Milkshakes that I made a couple weeks ago, but I used it to top a peach cobbler! Now I’m wishing I’d seen this first!

Kate L

So, I generally don’t have cake mixes. Is there something I can substitute?

Sommer @ ASpicyPerspective

These are amazing, Shelly!

Melanie @ Just Some Salt and Pepper

These look insanely delicious!

Jamie @lifelovelemons

Cake batter smores?! Oh. My. God.

Stephanie @ Macaroni and Cheesecake

Homemade Marshmallows are the jam! And this version looks so fun and festive!! These would be awesome on s’mores!

Rachel Cotterill

I’ve been trying to make vegetarian marshmallows… it’s much harder when you can’t eat gelatine! I haven’t quite managed it yet but I’m getting closer, need to try it when the humidity is lower, I think. Yours look so cute and colourful 🙂

Ali | Gimme Some Oven

Um, these are BRILLIANT. Love the sprinkles too!


YUM-O!!! Cake batter & marshmallows together- I’m all over it.


Can this recipe be doubled for a 9″ x 13″ pan? I am embarrassed to admit that I never owned an 8″ x 8″ pan!! That size is just too small for my family and all their friends that hang out at my house! Thanks for sharing-can’t wait to make them!!
