When I think of summer treats, I think of warm and gooey s’mores! These Protein S’mores Bars are a fun alternative when you don’t have a fire pit or somewhere to roast your marshmallows! And let’s face it, protein treats are never as good as the real deal. That’s a fact. Sometimes it’s nice to just have a buttery, sugar filled treat and move on with your day. However when you want to fit a treat in your day, or satisfy a craving without breaking the macro bank, a treat with added protein that has been lightened up, can be nice. Try these out this summer and see just how yummy they are!

  • 1/2 cup butter, room temperature
  • 1/4 cup swerve brown sugar
  • 1/2 cup swerve sugar
  • 6 tablespoons egg whites
  • 1 tsp vanilla extract
  • 1 cup all purpose flour
  • 3 scoops CSE Simply Vanilla protein powder, 99g
  • 4 graham cracker sheets, crushed
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 3.5 ounces Jet-Puffed marshmallow creme
  • 1.5 Hersheys milk chocolate bars, 110g


  • Preheat oven to 350 degrees. Spray 8×8 inch square baking pan with cooking spray.
  • In a large bowl, cream together with a hand-held electric mixer, butter and sugars until light and fluffy. Beat in egg whites and vanilla.
  • In a small bowl, whisk together flour, protein powder, graham cracker crumbs, baking powder and salt. Add to butter and sugar mixture and mix at low speed until combined.
  • Divide dough in half and press half into an even layer on the bottom of the prepared pan.
  • Spread marshmallow creme over the bottom layer as best you can. Break apart the Hershey’s bar and evenly spread out the pieces.
  • Take the remaining dough and layer it over the top. It’s okay if there are uncovered sections of marshmallow and chocolate.
  • Bake for 20-25 minutes, or until lightly browned. Let cool at least 20 minutes before cutting and serving.


Don’t over cook these! I suggest taking them out right when you’re questioning if they’re cooked enough. If you over cook them, they will be dry, I’d hate for that to happen!
