Crumbl Copycat: S’mores Brownie Cookies
Brownies and cookies are my 2 all time favorite treats! So when a follower messaged me on Instagram and requested I make this Crumbl Copycat recipe, I couldn’t resist.
Half decadent, chocolatey brownie, half graham cracker flavored cookie, topped with marshmallow and overflowing with S’more’s flavor. These cookies they will have you singing Kumbaya in no time!
Best news yet- you don’t have to make two separate cookie doughs for this one cookie! That’s right, we will make one dough, separate at the last minute and add in a few last items to make two completely different cookie doughs.
Ingredients in Crumbl S’mores Brownie Cookies
- Butter- You can use salted or unsalted. I always use salted because that is what I have on hand.
- Granulated sugar
- Brown Sugar- Using both types of sugar will give you cookies the best texture, and the brown sugar helps keep the cookies nice and soft.
- Flour- The flour in the recipe is divided. Make sure to not add it all to the dough initially.
- Baking Soda
- Baking Powder
- Salt- Using salt in desserts helps bring out the sweetness, desserts fall a little flat with out it!
- Crushed Graham Crackers- About 1 1/2 cups worth (exactly one package crushed!), plus a little extra for garnish
- Cocoa Powder
- Chocolate Chips- You will need sweet and semi-sweet chocolate chips in this recipe.
- Marshmallow Cream
How To Make S’mores Brownie Cookies
Start by preheating the oven to 350 degrees.
In a stand mixer cream together the butter and sugars until light and fluffy. Add the eggs and vanilla and mix until combined.
Add 3 1/2 cups flour, baking soda, baking sugar and salt and mix until just combined. Be careful not to overmix once you have added the flour or your cookies will become tough and cakey.
Take half your dough and place it in a separate bowl.
Add the graham cracker crumbs and chocolate chips to the stand mixer and mix again. Once your cookie dough is combined, remove it from the stand mixer.
Return the remaining dough to the stand mixer and add the cocoa powder, and the remaining flour and stir to combine.
Divide the brownie cookie dough into 12 equal parts. This makes huge cookies, if you want smaller cookies you can do that too, but you will need to adjust the bake time.
Roll each chocolate portion into a ball and place on a cookie sheet, (6 per pan, the dough will spread a little bit) and flatten with the palm of your hand.
Now divide your graham cracker cookie dough into 12 equal parts. Roll them into a ball, flatten the dough with your palm and place on top of your brownie cookie.
Bake at 350 for 12-15 minutes being careful not to overbake. You will know they are done when there is no longer a wet spot on the top of the cookie.
Allow the cookies to cook on the cookie sheet for 10 to 15 minutes before spooning the marshmallow cream on the center of the cookie and garnishing with graham cracker crumble. (also, hi there Mr. Twix bar!))
How to store Leftover Crumbl Cookies
Store any leftover cookies in an air tight container- I usually put them in a deep 9×13 pan and then cover tightly with plastic wrap. This will keep them fresh at room temperature for 3 or so days. If you’d like them warm again, just pop them in the microwave for a few seconds.
