    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!). My kids loved this because it was a little more flavorful than the traditional cereal marshmallow treats.

    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 occasionally also allowed this as a cereal on-the-go breakfast treat.  It is cheaper than the prewrapped cereal bars you buy at the grocery store!

    Some of my kid's other favorite cereal treats include these Easy Scotcheroos, these peanut buttery Special K Bars, and these Easy Cheerio Cereal Bars

    Why I love these Reese's Puff's marshmallow treats

    • This is a delicious peanut butter and chocolate-flavored cereal. That's just such a great flavor combination!
    • This is a no-bake recipe. That's especially great when you don't want the oven on in the summer.
    • This recipe for these peanut butter and cereal treats is easy! Melt the butter, melt the marshmallows, add the cereal. You've done most of the work!
    • The prep time is less than 10 minutes. Then you need to wait for them to cool. That's it! Quick, easy, and delicious!!

    Ingredients

    I have recalculated the ingredients for marshmallow cereal treats so that you don't have partial containers of ingredients left over that you need to store.

    Butter - I use salted, but unsalted is fine.

    16 oz bag of marshmallows  - Use fresh marshmallows.

    13 oz box of Reeses Puffs cereal (chocolate & peanut butter flavor).
    The picture above shows the box you should be looking for.

    Marshmallow tips - It doesn't matter what brand you buy, but get fresh marshmallows. That will help with ensuring that the final cereal treat isn't hard. Also, the small marshmallows melt quicker and easier.

    Instructions

    Step 1
    Melt butter in a heavy pot. The heat should be at medium-low.

    Step 2
    Add marshmallows into the butter. Stir until the marshmallows are just melted and then turn the heat off.

    Step 3
    Add the whole box of cereal. Stirring quickly so that cereal is covered with marshmallows is important. It gets harder as the mixture cools.

    Step 4
    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.

    The cereal treats were so nice and 'marshmallowy' and nice thick pieces.   I cut 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.

    Enjoy these delicious cereal treats!

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

    Storage

    Room Temperature - Keep in a sealed zip-type bag or a well-sealed container. I find the cereal treats are good up to about 5 days.

    I recommend you do not refrigerate. They get hard and taste stale.

    Freezer - I recommend you wrap in plastic wrap and then place in a freezer bag. Typically, these types of treats are fine in the freezer for 3 to 4 months.
    Make sure to thaw at room temperature (sitting on the counter for about 1 hour). Frozen cereal marshmallow treats are hard, and I wouldn't recommend biting into them until thawed.

    FAQs

    Why do my cereal treats turn out hard?

    Make sure you don't overcook the butter and marshmallows. You need to work quickly once the butter has just melted and turn the heat off as soon as the marshmallows have melted.

    Can I use the jarred marshmallows?

    Yes, the marshmallow fluff works well. Make sure you do not overcook since these are already melted.

    Ingredients

    • 5 Tbs. butter
    • 16 oz marshmallows
    • 1 box Reese's Puffs cereal 13 oz box

    Instructions

    • Melt butter at low-medium heat.  You don't want to brown it.
    • Stir in 16 oz bag of marshmallows.  They will melt into the butter.  Stir continually until the marshmallows are all melted and the mixture is smooth. Turn off stove.
    • Add the full 13 oz box or Reeses Puffs cereal (chocolate and peanut butter flavor, of course!)
    • Press into a 9 x 13 pan (I use a casserole dish)
    • I like to cut the pieces after the cereal treats have cooled a bit but are still warm.

    Notes

    ***tip - Put your hands in a food baggie and spray the outside with cooking spray.  Makes it much easier to press the cereal down.  Your hands don't get as messy

      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.
