I put a summer twist on Fit Foodie’s protein brownies, and it obviously had to include marshmallows, graham crackers, and Hershey’s chocolate. Introducing these yummmmmy protein s’mores brownies 🥰🥰. The s’mores toppings makes you feel like you’re at a campfire and I’m not mad about it.

S’mores is one of my favorite flavors of summer! If I’m not making these peanut butter crunch s’mores cookies or these frozen protein s’mores, you bet I’m making these s’mores brownies 😋😋.
It’s a fun recipe to involve the kiddos: Gus loves helping me add the s’mores toppings to these brownies before baking 🥰.
Chewy, fudgy brownie perfection: I love love love a fudgy brownie, and even though this recipe uses protein powder instead of cocoa powder, they’re still so decadently chewy and fudgy.

Pro Tips for S’mores Brownies
Use a metal baking dish: avoid using a ceramic or glass baking dish if at all possible! A metal baking dish will give you more even heat distribution, which will leave to more evenly baked brownies.
Use whey protein powder: I prefer the taste of Tera’s Whey chocolate protein powder over other whey protein powders, but any whey protein powder will work. I have NOT tested this recipe with plant-based protein powder.
Add more mini mallows at the end: right after the brownies come out of the oven, I love adding more mini marshmallows. They’ll melt and become ooey, gooey delicious as the brownies cool.

Peanut Butter Crunch S’mores Cookies
Love s’mores as much as me? Try these crunchy peanut butter s’mores cookies. Yum!
Let these s’mores brownies cool completely before slicing them into squares and storing them in an airtight container for 3-5 days. If you don’t let the brownies cool before storing them, they will become soggy.
Let the brownies cool and then store them in a freezer-safe container. Freeze them for up to 3 months.
