What You’ll Need
- box of brownie mix + ingredients needed on box– I generally use Ghirardelli for the brownie mix.
- red velvet cake mix + ingredients needed on box– Any red velvet cake mix works great such as Duncan Hines.
- canola oil– Oil is added to the brownie mix and cake mix.
- butter– For most of my recipes I use salted, but unsalted works great too.
- large eggs– For consistency I use large eggs in my cooking and baking.
- graham crackers– Full graham cracker sheets are layered between the brownie and cake mix layers.
- mini marshmallows– Mini marshmallows get layered between the graham cracker and cake mix layer.
- sweetened condensed milk- Sweetened condensed milk gets drizzled over marshmallows.
How To Make S’mores Bars
- Preheat oven to 350 degrees F. and line a 9×13 inch baking dish with parchment paper.
- Prepare brownie mix according to package directions and pour into bottom of prepared baking dish. Layer with Sheets of graham crackers, chocolate chips, marshmallows and drizzle evenly with sweetened condensed milk.
- In a large mixing bowl, add red velvet cake mix, melted butter, egg and oil, mixing until dough forms. With a cookie scoop, scoop dough over marshmallow layer then press dough so it’s flattened. Bake for 40-45 minutes, until baked through. Let cool completely. Takes a few hours. Best if prepared at night then let cool overnight. When cool, cut into squares and serve.
Transfer the batter to a 9×13 inch baking dish.
Layer with graham crackers then top with chocolate chips!
Marshmallows next please. Drizzle with sweetened condensed milk.
Scoop the red velvet dough over the marshmallows then flatten out like so. Bake for 40-50 minutes and….
Hello layers.
Such a festive bar. Great for neighbor gifts too! They look great wrapped up. Can’t wait for you to try these! Enjoy.
How To Serve Red Velvet Bars
Serve red velvet bars for any occasion where a dessert is needed. The red colored dessert is perfect for Valentine’s Day and Christmas along with so many other occasions.
How Do I Store These Cookie Bars?
Store any leftover bars in an airtight container for up to 3 days on the counter.
Tips For Making The Best Cookie Bars
- Don’t alter the recipe, use all ingredients as listed.
- Always use butter, not margarine. ALWAYS. I prefer salted butter for my chocolate chip cookies. Try it!
- Don’t overtake your cookie bars. Bars will continue to cook on hot cookie sheet when removed from oven.
- Let cookies cool completely before cutting into squares and storing in containers. This will keep their crispness.
- Store leftover cookies in an airtight container for 3 days room temperature.

I purchase red velvet brownie mix instead of cake mix. will this make a difference?
Oh my…these are a must try. Bet they make a GREAT comfort food.
Personally, I wouldn’t try skipping the condensed milk, Nina – but that’s just me, maybe Jenny has better input on that…
These look amazing! Will skipping the condensed milk make a big difference?
Hi Nina, you could do these without the condensed milk, but they will not have the “gooey” factor that makes these fabulous 🙂
Hi Jenny! I just made these bars tonight. 🙂 We are hosting family dinner tomorrow night and these bars are for our dessert!! Thank you for sharing your awesome talent with us!! I will reply on here tomorrow and let you know how we all liked them. 🙂
Wonderful! Let me know how it goes 🙂
CRAZY AMAZING!!! WOW!!!! HUGE RAVING HIT at family dinner! They are all gone!! The entire 9 x 13 pan! Right now I am wishing I had one leftover for myself. 😉 I made them exactly according to your recipe. I even used parchment paper and lined the baking dish. I really liked that trick. THANK YOU JENNY!! I am looking for a reason to make them again! 🙂
So glad to hear it Kristen 🙂 Thanks for the feedback 🙂
OMG Jenny, these were fantastic! I made them last night (super quick and easy) and brought them to work for Valentine’s Day today, and the whole pan was gone within the hour. Thanks for sharing! 🙂
Going to make these tonight! But can I just use cooking spray instead of the parchment paper?
These look so delish!
Yum! You’re not the only one; I can eat sweetened condensed milk out of the can as well!
Haha! Glad I’m not the only one!
All. These. Things! You had me at the title – love, love, love your bars. Can I have 5, please??
Oh my gosh!! what and amazing creation, Jenny! I cannot wait to bake these up!
OMG, all of my favorite things in a delicious bar! I will be making these for Valentine’s day, thanks for sharing! Pinned 🙂
Ultimate Valentine treats! I can’t wait to try them!
FESTIVE indeed. It’s like a party!
How do you come up with these ideas?? Crazy Good!!!
Everything about this sounds amazing! Love! xoxo
Red velvet and s’mores are two of my all time favorite things! I could have just these bars and nothing else for Valentine’s Day and be totally happy. 🙂
Me too Beth!!
I made these this morning and used a Duncan Hines red velvet cake mix but mine turned out looking more like a chocolate cake mix. Not anywhere near the bright red top layer yours has. Any idea why this happened?
How weird Christina! You didn’t prepare the cake right? You just added the butter, egg and oil from my recipe? My cake mix was super bright red.
Yes I prepared it according to your recipe (not the back of the cake mix). Very weird cuz I used the exact same cake mix. Not sure what happened
Can I please just dive head first into them?! Full of some of my favorite things mmmm!
Yes, I’ll join you 🙂
So going to try this out! It looks way too good. Will report back on how well received it is!
OK! I am sold on these. Perfect for Valentine’s Day!
oh my gosh! these look insanely amazing!!! I love everything about it!!
This looks delish – and so perfect for Valentine’s Day!
OMG! Now, this would be a fabulous Valentine’s Day treat for the hubby!! xoxo
Thanks Lauren 🙂 xo
These look like they’re so jam packed with awesomeness!!
That looks like an over the top dessert dear. Fabulous for sure and I think I’ll be needing my running shoes after this one! 🙂
You and me both!!
Jenny, this is everything I shouldn’t make combined with everything I can’t resist! If ever a holiday demanding a dessert so gooey and over the top, it would be Valentine’s Day 🙂
Haha! I know. One bite and I try to get my goods out of the house, lol!
Wow! What a great treat for Valentine’s Day!
These brownies are fabulous!
These sound fabulous and they are a perfect V-Day treat!
These look insanely incredible!
Jenny, I’ll agree that the sweetened condensed milk is deadly, but the same could be said for you! I just love your creations! 🙂
Haha! Thanks Karly 🙂
Jenny, these are too fun. I’m moving in!
I can’t WAIT to try these. Honestly amazing!
Lol @ getting them out of your house ASAP…that is my life.
Until, I saw these bars. Now, these are my life!
So much ooey gooey chocolate. I am dying. Pinned!
