Gooey S’mores Crumbl Cookies (Vegan copycat!)
These gooey s’mores Crumbl-style cookies are made for dramatically breaking apart, melting slightly in your hands, and eating while warm. Thick and vegan, this cookie recipe is packed with graham cracker flavour, pools of melted chocolate, and soft, stretchy marshmallows baked right into the centre. Crispy on the edges, and soft in the middle, they bring the campfire nostalgia perfect for baking days in the kitchen with friends.

I’ve been cooking for over 15 years, but my wife’s been baking for even longer. I still pick up on things from time to time, and her world famous cookies happens to be one of them. I was never a big sweets guy, but I always had a sweet spot for cookies, and with the success of the best chocolate chip cookie recipe ever, I wanted to mimic that base so that I could be sure of an instant cookie victory.
My Crumbl copycat cookies were developed because I wanted the crumbl experience. Thick, bakery-style indulgent cookies without the dairy or eggs. They also lack the disappointment that frequently accompanies vegan copycat recipes!
Countless batches later, each one taught me a thing or two about how fat, sugar and heat behave when you’re trying to come up with something that tastes familiar, and in my opinion, better!
Big cookies over small cookies, any day
My kind of cookie isn’t dainty or crumbly (pardon the pun), they’re intentionally oversized, rich and built for being gooey. A lot of s’mores desserts miss the mark, in my opinion, because they lean too hard on sugar and forget some of the basics (that’s doubly true for some vegan baking recipes). Here’s what makes my cookies work:
- The graham cracker flavour is baked separately from the dough. This helps the dough to rise perfectly and set before the toasted nuttiness of the homemade graham cookie can be added afterward.
- My chocolate is always added in chunks, not chips! you want uneven chocolate-y pools that melt at different rates for texture and eye appeal? Chunks every time.
- Placement of marshmallow matters. I always try and tuck as much of any exposed mini marshmallow into the dough before baking. Any exposed bit runs the risk of burning and drying out.

Chill if you want a thick cookie
Chill my shaped cookie dough briefly before baking… even if you’re impatient! The short rest firms up some of the fat and slows the spread of the cookies. One of the keys to a thick cookie like mine.
Cookie dough is a delicate thing!
But that doesn’t mean it’s complicated. After multiple test runs and taste tests. Lots of taste tests… I learned when my dough is pushed a little too far. Over-mixing led to a few dense batches, and under-mixing led to a cookie that quickly collapsed from weak, uneven spots.
You want this dough to be slightly tacky, and perfectly combined. This takes a bit of intuition, but I have a few tests will help you determine when this dough is at its best.
- They hold together when squeezed, but break cleanly in my hand when pulled apart.
- When I press a finger into it, I want the imprint to stay without any of it coming back off onto my finger.
- Visually, I just check for well rounded, even balls and no pockets of dry flour that went unmixed.

Adding crunch without ruining the gooey centre
One things that I pivoted to early in my testing was moving the texture from the inside of the cookie, to the outside. By that I mean, keeping the integrity of the soft centre intact, and adding a layer of crumbly sugar cookie to the outside for the iconic s’mores crunch.
This decision was to avoid a dry centre to my cookies. Sprinkled over warm cookies, my sugar cookie crumbles add a toasty, sweet crunch you get from real graham crackers without messing with the flavours of the marshmallow, chocolate and cookie dough base.

Description
These gooey s’mores Crumbl-style cookies are made for dramatically breaking apart, melting slightly in your hands, and eating while warm. Thick and vegan, this cookie recipe is packed with graham cracker flavour, pools of melted chocolate, and soft, stretchy marshmallows baked right into the centre. Crispy on the edges, and soft in the middle, they bring the campfire nostalgia perfect for baking days in the kitchen with friends.
Ingredients
- 1/2 cup vegan margarine, vegan butter or coconut oil (SEE NOTE*)
- 1 cup brown sugar
- 1/3 cup non-dairy milk (like almond or soy)
- 1 tsp vanilla
- 2 cups all-purpose flour
- 1 tsp baking soda
- 1 tsp baking powder
- pinch of salt (about 1/4 tsp)
- 1/3 to 1/2 cup dairy-free chocolate chips
- 12–15 mini marshmallows (or 4 large marshmallows)
- 3–4 tbsp of vegan chocolate syrup
Instructions
- preheat oven to 350 F (SEE NOTE**)
- In a mixing bowl, cream together vegan margarine and brown sugar. Add almond milk and vanilla and stir to combine.
- In a separate bowl, whisk together flour, baking soda, baking powder and salt.
- Add dry mixture to wet in two parts, stirring to form a dough. set aside approximately 3 tbsp of dough and spread thinly on a baking sheet to brown for crumbling on top of the cookie.
- Add chocolate chips to the dough and stir to combine.
- Use an ice cream scoop size of dough and roll into balls. Rip each ball in half turning the raw sides upwards before gently sticking back together for a crumbly textured top. place on a cookie sheet next to the thinly spread cookie dough. Bake 9-11 minutes or until golden. Bake on broil for extra 1-2 minutes if you want the cookies and marshmallows to be more browned.
- Let cool a few minutes and crush up the flattened hard cookie to a crumble. Sprinkle on top of the cookie and add vegan chocolate sauce before devouring!
Notes
I use soft tub margarine for my cookies (Becel brand- the vegan one). If you are using vegan butter or coconut oil I suggest adding an extra tbsp or two of the plant-based milk because they will have less moisture than a soft tub margarine. I notice that my cookies always flatten out nicely, but some of you have had trouble with the cooking not spreading and I think it is just due to your fat having less moisture! I hope this helps. 🙂
I started baking them at 375 F and this helps them get more golden brown and slightly crispy on the outside. Baking at 350 F results in chewier cookies that are lighter in colour and take a little longer to cook)
Best cookies ever, loved by non-vegans who have no clue!!
so glad you loved them! They’re my absolute favourite right now!
When do we add the marshmallows?
Add on top of dough right before baking 🙂
