If you’re entertaining for the Opening Ceremony, try setting up a festive USA S’mores station with these delicious homemade marbled marshmallows, HERSHEY’S Milk Chocolate Bars and some cracker or cookie base!

We also love using this electric S’mores maker. It is pretty awesome and uses hot air to toast the marshmallows. I actually never knew that it existed until I tried this one and was super impressed. So fun to have a little S’mores station inside and obviously a hit for kids and adults!

    • Hi! I will update this! You add it at the end once it’s pretty much already a thick marshmallow texture. You can just pour it in and then give it one more good mix!
