I think my particular recipe for these 5-ingredient Peanut Butter Rice Krispie Treats is the absolute perfect balance between chewy and crunchy and peanut butter. FREQUENTLY ASKED QUESTIONS: Can I use other cereals with this recipe? I have made this recipe with the store brand cereal, marshmallows, butter and peanut butter and these treats still turn out delicious. You do not need to use name brand. Also, Cocoa Krispies work perfectly with this recipe too! They’d be a fun chocolate and peanut butter flavor combination that we know so many people enjoy. What if I want a thinner bar? If you prefer a slightly thinner Rice Krispies treat, use a 9×13-inch baking dish instead of a 9×9-inch baking dish will do the trick. What else can I add to these? Options are endless here guys. Over the years, you know you’ve made thousands of these things. You can add sprinkles, top with any baking chip like white chocolate chips, peanut butter chocolate chips, mini chocolate chips, dark chocolate chips, etc. You can add crushed candies into the mix. Additionally, you could melt some chocolate and pour it over the treats before you cut them. You know the deal, you can get creative and add anything you like the flavor of peanut butter with! Why did my Rice Krispie Treats with Peanut Butter turn out hard? Usually this happens if you used too much heat. Using low heat to melt the butter and marshmallows is key. I know it can be tempting to turn up the heat to speed up the process but that’s risky. You could burn the butter, marshmallows or just make hard treat bars and nobody wants that! Just take the time you need to make these correctly. Can I make these in advance? Of course you can. Just be sure to hide them well so you don’t end up eating them all before you plan to serve them. Just kidding, you can make them up to a day in advance and store them appropriately. It is worth mentioning that these do taste best the day that you make them, but they do make a good make ahead treat if needed. How so I store Rice Krispies treats? As with all Rice Krispies treats, they are best eaten the day they are made.Store in an airtight container if you don’t eat them all the same day. I like to warm them up in the microwave for about 5-10 seconds when they start getting a little stale.
