Ingredients needed for these S'mores bars
Notes
- Brown sugar: Both light brown sugar and dark will work here.
- Chocolate chips: I use milk chocolate chips but semi-sweet chocolate chips are fine to use or even chopped Hershey bars.

- Step 9: Sprinkle chocolate chips on top.
- Step 10: Place the remaining cookie dough on top of the marshmallow layer, sprinkle graham cracker pieces, chocolate chips, and extra mini marshmallows bake until golden brown and bubbly.
Recipe Tips
- Allow the bars to cool completely before cutting them into squares. This will help them set properly and make it easier to slice without making a mess.
- Make sure you line your baking pan with parchment paper or foil it helps to remove them from the pan to cut.
- Use a wet knife to spread the marshmallow layer, it can be pretty sticky.
- You can make your own graham crackers crumbs by using a food processor, takes about 9 graham crackers to make one cup.
Recipe Faq's
Yes, Once completely cooled place it in a large ziplock freezer bag and freeze for up to 3 months.
No regular marshmallows will just melt into your cookies. Marshmallow fluff makes these cookies super gooey and delicious!
I prefer milk chocolate chips, but semi-sweet works great also. You can use chocolate chips, Hershey's chocolate bars, or even chocolate chunks.
