Photo tutorial
In a large bowl using a hand or stand mixer fitted with a whisk or paddle attachment mix the butter and brown sugar just until combined for about 1 minute.
Add the egg and vanilla and mix just until combined, which takes about 1 minute.
Then add graham cracker crumbs, flour, baking powder, and salt and mix just until combined, another 1 minute.
Using a rubber spatula or wooden spoon, fold in the mini marshmallows and chocolate until incorporated.
Spoon 12 evenly sized cookies on the prepared baking sheets with about 4-inch space in between.
Bake the cookies for about 9-11 minutes. Please don't overbake your cookies. Remove them from the oven as soon as they start looking dry on the tops, puffed, and pale.
Let them cool on the baking sheet for about 10 minutes. Then transfer the cookies to a wire rack and let them cool completely.
Baker's Tips
- Don't overmix the batter at any point.
- Make sure not to overbake them.
Substitutions
Graham crackers
You can make them without graham crackers if you'd like. Simply replace the ground graham crackers with any other favorite cookie like a wafer. You could also substitute regular graham crackers for a chocolate variety of graham crackers too.
Just note that the graham crackers give the cookies that traditional s'more flavor, so substituting will change the flavor a little.
Chocolate bars
You can also make them with chocolate chips instead of chocolate bars. Simply substitute the same amount of chocolate chips (¾ cups - 135 g) in place of the chocolate candy bar. You can choose any variety of chocolate you prefer, but milk chocolate is what I usually use.
Additional flavors
Fold any of these ingredients into the dough when you add chocolate and marshmallows.
- 1 cup (125g) nuts - Almonds, pecans, pistachios, or walnuts would be great!
- ½ cup (88g) white chocolate chips
- 1 cup (175g) crushed mint chocolate candy
FAQ's
Should I Flatten The Cookies Before Baking?
No, you do not need to flatten out them before baking. While some recipes do require you to smash the cookies down, these cookies will flatten naturally as they bake.
Do I Need To Grease The Pan For Cookies?
No, as a matter of fact, if you do grease the cookie sheet, then the result is going to be thin and flat cookies. Grease causes the cookies to spread out more than they usually would, so skip greasing the pan.
What Happens If You Overmix Cookie Dough?
When making this recipe, be careful not to overmix the dough. If you do overmix it, then you will end up with tiny air bubbles in the batter. This will cause the cookies to become flat and not as delicious.
Storage
You can store them in an airtight container for 4 days at room temperature. Make sure they have cooled all the way before putting them in a storage container because otherwise, they will become mushy from condensation.
Freezing
Typically, marshmallows do not freezer well, but because of the sugar content in the cookies, you shouldn't have any issues.
Make sure to store the cookies in an airtight freezer bag or container to keep them from freezer burn. They will last around 3 months.
