Line a 9-inch square baking dish with parchment paper. Set aside.
In a large saucepan, melt butter over medium heat. Once melted, add in all but 1 cup of the marshmallows. Reduce heat to low and continue stirring until completely melted.
Remove from heat and stir in the vanilla. Add the cereal and the remaining 1 cup of marshmallows and gently stir until combined.
Pour into the prepared baking dish. Press GENTLY with your fingertips just until completely spread out (the harder you pack them in, the harder they are to eat).
Allow to set, about 1 hour. Cut and enjoy!
Notes
How many marshmallows do I need? One 16 ounce bag of marshmallows is about 8-9 cups. You’ll melt all but one cup of the marshmallows in the butter, reserving the last cup for adding with the cereal.
Line a 9-inch square baking dish with parchment paper. This way you don’t have to worry about extra butter on your fingertips, or the other extreme of your bars sticking to the pan! Use binder clips to help the parchment paper stay in place.
Use fresh marshmallows. Seriously, they make a difference. Don’t grab that bag that’s been in your pantry for months and months thinking it will be okay since you are melting them. It won’t be okay.
Add my secret ingredient. VANILLA EXTRACT. Not imitation vanilla, but PURE VANILLA extract. It makes a difference in creating the illusion that you’re using homemade marshmallows.
DO NOT (I repeat) DO NOT press these bars into your pan firmly. Using your fingertips, GENTLY press them in just until they are spread out. The harder you pack them in, the harder they are when it’s time to eat them!
The trick to pressing them in your pan without sticking to your hands is to run your fingers in water, shake off the excess, and press. Voila. No sticking!
Store in an airtight container for two days. If they last that long, I’d be shocked!
Make these gluten free by choosing a crispy rice cereal labeled Gluten Free (and check your marshmallow labels too just in case).
