Equipment

large pot for melting butter, marshmallows, and mixing ingredients together
9x13" pan

Ingredients

4 tablespoon butter
5-6 cups mini marshmallows or 300 grams of any marshmallow you want
2 scoops protein powder
5 cups high protein cereal see notes

Instructions

Put a large pot on the stove under medium-low heat (I used my Dutch oven). Add the butter and let it melt.
Add the marshmallows to the melted butter and stir. Cook on medium-low heat until melted. If your stove doesn't run as hot, you can use medium heat. Just be careful not to burn the marshmallows. As the marshmallows melt, prep the dry ingredients so they're ready to go.
Measure out the cereal into a large bowl and set aside. Add 2 scoops of protein powder to another small bowl. Once the marshmallows are melted, you need to work quickly, so having these prepped is important.
When the marshmallows are melted, turn off the heat. Add the protein powder and stir continuously until it is dissolved.
Add the cereal to the melted marshmallow/protein mixture. Stir, stir, stir. Work quickly and don't stop! You're on a short timeline until this marshmallow mix starts to get hard.
Scrape the cereal mixture out of the pot into a greased 9x13" pan. Press mixture into an even layer. If needed, lay a piece of parchment on top and press firmly with your hands to even it out.
Feel free to cut the bars immediately. You can cut & serve right away, but they will continue to get firmer as they sit.

Notes

-I am using Three Wishes high protein cocoa cereal, but you can use any brand and any flavor.

-I am using Legion Whey Chocolate protein. This has only been tested with whey protein, but would most likely work with other types if you'd like to try it.

-After the marshmallows are melted, be prepared to work quickly. Have the protein powder, cereal, and a greased 9x13 pan ready to go so there's no delay. These bars start to harden very fast! As they harden, they're harder to work with.

-If the bars are starting to harden before you have them pressed in the pan, lay a sheet of parchment paper on top of the cereal mixture and press firmly with your hands to even them out in the pan.

-There may be a sticky mess left over in your pot. Get it soaking in warm soapy water shortly after pressing the bars into the pan.

-Store these bars in an airtight container at room temperature. They will be firmer on day 2 and beyond. I recommend eating within 3 days for optimal texture.
