Halloween treats don’t have to be complicated to be fun—and these Oreo Protein Rice Krispie Treats prove it. They’ve got everything you love about the classic gooey marshmallow squares, but with a festive twist: crushed Oreos, candy eyes, and a boost of protein to keep them a little more balanced. The best part? They come together in just a few minutes, no baking required.
I love recipes like this for parties, school events, or just a fun family night at home. The decorating is simple enough for kids to help with, and the end result is equal parts spooky and delicious. Plus, adding protein powder makes them a little more filling, so you’re not left with a sugar crash after enjoying one. Trust me, these will disappear from the tray faster than you can say “boo”!
