More About This Recipe

  • This is what you get when you mix a s'more, a marshmallow cereal treat and a cupcake!

    Using Peanut Butter Toast Crunch cereal, a little vanilla cake mix and a delicious marshmallow frosting, you can create this amazing, crunchy and very tasty treat. We call 'em PB S'mores Treats!

    Start with Peanut Butter Toast Crunch. It adds the peanut butter taste and the ... crunch!

    Then mix up the crispy bar part. Melt the marshmallows and butter, then add cake mix, vanilla and chocolate. Mix in the cereal and voila!

    Press the crispy chocolate mixture into greased muffin cups and refrigerate while you whip up the marshmallow-fluff frosting.

    Pop the crispy rounds out of the muffin tins. They have the taste of peanut butter s'mores and the texture of a marshmallow cereal treat. A winning combination!

    The marshmallow fluff frosting is lightly sweetened so it balances out the sweet crispy bottom. I think they turned out super cute and very tasty!

    It's a great no-bake dessert and adorable for a kid's party, as the party goers will totally love them!
