Chocolate Peanut Butter Cereal Marshmallow Treat
These chocolate peanut butter cereal marshmallow treats are quick and easy to make. Plus, it's a treat that doesn't need to be baked! Perfect for the summer (or any other time of year!).
I have recalculated the ingredients for marshmallow cereal treats so that you don't have partial containers of ingredients leftover that you have to store??
This cereal treat was very popular with my kids. Who doesn't like something with both chocolate and peanut butter flavors! It was a great snack to take along. During crazy mornings, I sometimes also allowed this as a cereal on-the-go breakfast. It certainly is cheaper than the prewrapped cereal bars you buy at the grocery store!

I used the whole box of cereal and the whole bag of marshmallows. The cereal treats were so nice and 'marshmallowy' and nice thick pieces. I made a point of cutting the pan into individual pieces once it was cooled (but not cold - as in refrigerated). This is easier to cut once it has cooled to room temperature.

Super quick.
Ingredients
5 TBS. butter, melted in a large pot (I use a heavy stockpot). Heat at about medium.
16 oz bag of marshmallows - melt in the butter and stir until all melted and smooth.
1 13 oz box of Reeses Puffs cereal (chocolate & peanut butter flavor)
Instructions
Melt butter
Add marshmallows in butter
Add box of cereal
Press into a 9 x 13 pan sprayed with nonstick spray. I usually put a baggie on my hand and spray it. Then press the cereal down. It protects my hand from the stickiness and the hot melted marshmallow.
I wait for the cereal bars to cool a bit but cut them while they are still a little warm. Enjoy these delicious cereal treats!

These cereal treats are so marshmallowy! Is that a word? But you know what I mean!

Great idea and so simple too. Just like rice krispie treats we used to make but with the delicious taste of chocolate and peanut butter.
