What Are Peanut Butter Rice Krispie Bars?

Rice Krispies Treats are a no-bake dessert commonly made through binding Kellogg’s Rice Krispies or another crisp rice cereal together with butter or margarine and marshmallow. Though they are traditionally home-made, Kellogg’s began to market the treats themselves in 1995.

Homemade Rice Krispie Treats are also known as Rice Krispie Bars and Rice Krispie Squares.

Our favourite recipe adds another breakfast favourite, creamy peanut butter. Peanut Butter Rice Krispies are a chewy dessert which can be served as a sweet snack when sliced into bars or squares.

We add additional nutty flavour by topping the squares with roasted peanuts or candied peanuts and peanut butter chips.

What Are Rice Krispies?

Rice Krispies are a breakfast cereal, marketed by Kellogg’s in 1927 and released to the public in 1928.

Rice Krispies are made of crisped rice (rice and sugar paste that is formed into rice shapes then cooked, dried and toasted), and expand forming very thin and hollowed out walls that are crunchy and crisp. When milk is added to the cereal the walls tend to collapse, creating the brands signature “snap, crackle and pop” sounds.

While it is most commonly enjoyed at brunch in a bowl with milk and fresh fruit, this Peanut Butter Rice Krispies recipe is our favourite way to eat the crunchy cereal. A simple and satisfying dessert!

Peanut Butter Rice Krispies Recipe Tips

If it’s your first time making Peanut Butter Rice Krispie Bars at home be sure to review our detailed step-by-step recipe below. Here are some helpful tips and tricks to get you started:

We suggest using a high quality rubber spatula so you can easily stir and scrape down the side of the bowl as the melted marshmallows can easily stick to a wooden spoon. Spatula is always best!
You can prepare the marshmallow mixture in a pot over the stove or in a microwave using a microwave-safe bowl. We always use a microwave as it makes cleanup much easier.
Prepare the recipe in a non-stick square cake pan.
We’ve used butter in this recipe but you can substitute with any flavourless vegetable oil like canola oil, or melted margarine.
We’ve used creamy peanut butter but you can use crunchy peanut butter for additional texture.
We like to use mini marshmallows as they melt quicker but you can purchase large marshmallows and use a knife or scissors to cut them into smaller pieces.
We’ve topped the squares with roasted peanuts but you can use candied peanuts or beer nuts if you prefer.
We’ve added peanut butter chips to the squares but you can use chocolate chips if you’d like to add a cocoa flavour to the dessert.

What To Serve with Peanut Butter Rice Krispies

Rice Krispie Treats can easily be enjoyed on their own as a grab and go snack or late night dessert. The fact you don’t need to use any cutlery to eat them means it’s easy to sneak a slice without anyone knowing!

If you’re offering them as an after dinner treat, serve a chewsy square or bar with a hot pot of tea or coffee.

You can also serve a decadent ice cream sundae by placing a Peanut Butter Rice Krispie Bar in a bowl and adding a scoop of Chocolate Chip Caramel Banana Nut Ice Cream. Squirt with whipped cream, sprinkle with chopped peanuts and drizzle with chocolate fudge sauce.

You can also make Rice Krispie Treat Sandwiches by sandwiching two of the squares around a scoop of ice cream or gelato.

These Rice Krispie Bars are chewy thanks to marshmallows and peanut butter.

Is It Cheaper To Make Rice Krispies Or Buy Them?

Do some number crunching and you’ll find store-bought Rice Krispies Treats cost more than twice as much as a homemade recipe. They’re quick to make at home and especially fun to prepare with kids. We also love eating them fresh, still warm out of the tin.

Can You Make Rice Krispies With Stale Marshmallows?

Lack of moisture means old marshmallows don’t melt properly. Instead, the dehydrated marshmallows congeal into a thick mass. When making Rice Krispies treats, always opt for fresh marshmallows.

What Happens If You Put Too Much Butter In Rice Krispie Treats?

The best Rice Krispie Treat requires the perfect ratio of butter to marshmallow to rice cereal. Too much marshmallow and butter can make a super sticky, wet or soggy slice, while too little makes a hard, dry or crumbly one.

How Long Should Rice Krispie Treats Cool Before Cutting?

While you might be tempted to eat the chewy squares immediately after making them, let them cool for at least 30 minutes before cutting into squares or bars. The cooled marshmallow-cereal mixture will be much easier to cut. For easy cutting, unmold the pan of treats onto a cutting board.

Why Are My Rice Krispies Treats Hard?

It’s likely you left the marshmallow mixture on the stove or in the microwave for too long. Since the marshmallows have sugar in them, leaving it on the heat for a long period of time can cause the sugar to harden. To prevent this, make sure to remove it from the heat completely after melting down the marshmallows and peanut butter.

Why Are My Peanut Butter Rice Krispies Falling Apart?

You likely added too much butter, too many marshmallows, or you used a natural peanut butter with more liquid and oil in it causing the mixture to break down. If you follow the measurements in our recipe you should have no problem. Don’t eyeball ingredients be sure to measure them out exactly.

Can I Make Rice Krispie Treats The Night Before?

Homemade Peanut Butter Rice Krispie Bars are at their best the day they’re made. However, they can be enjoyed for up to 2-3 days if stored properly. Store Rice Krispie treats at room temperature, in a container or bag that seals airtight.

Can I Freeze Rice Krispie Squares?

If you want to store the bars for longer than two days, try freezing them! To freeze rice krispies, allow them to cool completely and cut them into squares. Wrap each square in a piece of wax paper and place them in a large freezer bag. Freeze for up to 3 months.
