If you’ve been following this blog regularly, you know how I feel about peanut butter and chocolate. This duo is one of my favorites and I am not shy about sayin’ it. In fact, I have tons of recipes on the blog that highlight this love affair of mine. Some of my favorites are:

  • Reese’s Pieces Peanut Butter Cookies – Soft peanut butter cookies loaded with chocolate chips and Reese’s Pieces
  • Chocolate Peanut Butter Souffles – Chocolate cake with a gooey peanut butter center
  • Monster Cookies – Peanut butter, M&M’s, oats, and chocolate chips. Need I say more?
  • Peanut Butter Hot Chocolate – A drinkable version of my favorite combo

I realized that it’s been far too long that I last shared a peanut butter chocolate recipes so I just had to bring you something new today. This recipe is incredibly easy and features this duo in a whole new way.

Check out my Reese’s Crispy Cereal Bars!

This crispy cereal bars are similar to rice krispy treats but with a bigger crunch from the bigger cereal and added richness from the Reese’s Pieces candies sprinkled throughout. I almost added more peanut butter to the melted marshmallow for even more PB flavor, but I held back. These bars stand so great on their own so there’s no need to get crazy just because I can.

These bars come together faster than you can imagine. If you’ve made rice krispy treats, they process for these bars is almost identical. If you have no experience making cereal bars before, have no fear! They are the easiest snack to make – promise!

First, we need to melt up the marshmallows to serve as our “glue” for the cereal. But if you just try to melt marshmallows on the stove or microwave on their own, they will be wayyyy to stiky to handle. So we also add melted butter to make the mixture more manageable.

Next, you add the melted marshmallow to the cereal and move quickly to combine them together with the Reese’s Pieces. As time passes, the marshmallow will cool and become stiff and hard to mix so it’s important to move fast.

The final sets are up to you. If you don’t mind a gooey bar, then go ahead and slice and eat the cereal bars without letting them set. I tend to fall into this category when I’m desperately trying to satisfy my sweet tooth.

But if you want the bars to look neat, with perfect edges, you must let them sit and set until the marshmallow has cooled enough to make the bars solid.

Now, I’ve already given you some pretty great tips above to ensure these bars come out perfectly. However, that didn’t keep me from thinking of a couple more:

  1. Don’t forget to grease you pan before adding the prepared mixture to it. That marshmallow goo is incredibly sticky so you’ll have a hard time taking the bars out of the pan without greasing it first.
  2. I find that a rubber spatula is the best tool to use to mix everything together and spread into the dish since the marshmallow doesn’t stick too much to it.

Okay people, there you have it – you’re next peanut butter chocolate obsession. I can’t wait for you to give it a try.

And hey, let this recipe inspire you to try all kinds of cereals in crispy bars. I’ve also tried them with Lucky Charms and loved it!

    My 3 year old always calls granola bars “cereal bars” – it’s his favorite quick and easy breakfast for his walk to preschool. It would totally blow his little Reeses-loving mind to know that these are also called “cereal bars” and I’ve been holding out on him whenever he asks for a cereal bar.. ha!

    I love this take on a ‘rice krispy treat’. I’ve always thought that the cereal in those really brought nothing special to the dessert. I love the idea of using peanut butter cereal to make this more interesting. I’m going to have to try this next time I’m packing a picnic.

    Could the butter be substituted for peanut butter?

      No the butter is used to keep the marshmallow mixture from sticking while it melts. The peanut butter doesn’t have enough fat to do the same.

    Reese’s Pieces have been one of my favorite candies since I was a kid! (I’d always order the Reese’s Pieces sundae at the ice cream shop.) I love the idea of using them in crispy cereal bars! What a fun and festive dessert to bring to a picnic or potluck. So great for guests of all ages!

Cheeseburger Egg Rolls – ground beef seasoned wi Cheeseburger Egg Rolls – ground beef seasoned with mustard and Worcestershire, stuffed with American cheese and pickles, all wrapped in a crispy wonton wrapper! Served with a tangy burger sauce for dipping! 

Frying foods is not always my favorite thing to do, you guys! But when I decide to, it's gotta be worth it! And these cheeseburger egg rolls are TOTALLY worth it! You just can't get the same crisp on the wonton wrapper in the oven or air fryer!

The filling is just like a classic cheeseburger – ground beef, American cheese, a pickle, and just a hint of mustard! And the burger sauce with ketchup, mustard, and relish rounds out those classic burger flavors!

Pro tip: Drain the beef extremely well! Any excess oil will put holes in the wonton wrapper while it's frying!

Perfect for appetizers, game day, parties, tailgating, or anytime you want cheeseburger flavor in a crispy, fun package! 🍟

Coconut Tres Leches – a tropical twist on the cl Coconut Tres Leches – a tropical twist on the classic! Spongy cake soaked in three milks (including coconut cream instead of heavy cream!) and topped with whipped cream and toasted coconut! 

Despite my Hispanic heritage, tres leches is something I only started loving in my 20s, you guys! And when I did? I was almost ANGRY I had waited so long to try it!

I love taking classic recipes and giving them unique twists! For this one, I replaced the heavy cream with coconut cream and topped it with toasted coconut – because I LOVE coconut cream cake! The result? The best of both worlds – all the tres leches flavor with all the coconut goodness!

Pro tip: Make this cake a day in advance and let it sit overnight! Tres leches gets BETTER over time, and it makes a world of difference!

One of the best desserts I've made in a while – seriously, your mind will be blown with every bite!

Italian Herb Wings with Gorgonzola Dipping Sauce – crispy baked wings tossed in garlic, Parmesan, and Italian herbs, served with a creamy Gorgonzola dipping sauce! 🍗

I've been obsessed with wings ever since high school when we'd have 25-cent wing nights at our local pub, you guys! These are a little bit of a step up from those days! 

Instead of my usual teriyaki wings, these are dry wings (not tossed in sauce) coated in the trifecta of flavor – Italian herbs, garlic, and Parmesan! And the best part? They're BAKED, not fried! You can put away that gallon of vegetable oil!

Pro tip: Dry the wings extremely well before coating – excess moisture keeps them from browning! And don't flip them during baking – the longer they're untouched, the deeper the skin will brown!

Perfect for football Sundays, tailgating parties, game day snacks, or anytime you want incredible wings without the fuss!

Peach Raspberry Cobbler – fresh peaches and rasp Peach Raspberry Cobbler – fresh peaches and raspberries topped with a cakey, cinnamon-sugar crust that's so incredible you won't even need ice cream!

Cobblers have stolen my heart, you guys! The first cobbler I ever loved was blackberry, but after tasting this peach raspberry version at a work potluck, it took the top spot! 

The secret? That cinnamon sugar crust! It's not just a topping – it's the STAR of the show! The combination of fresh peaches, tart raspberries, and that cakey, cinnamon-sugar-coated crust is pure summer magic!

Pro tip: Let the cobbler cool for at least 15 minutes before serving so the filling can thicken up and it'll be much easier to scoop!

Perfect for summer gatherings, July 4th parties, potlucks, or anytime you want a Southern dessert with a delicious twist!

Nutella Macarons – delicate French almond cookie Nutella Macarons – delicate French almond cookies filled with chocolate-hazelnut Nutella spread! Classic macarons made with the proper technique learned straight from a pastry chef! 

You guys remember when I made French macarons for the first time and they were a HOT MESS? The tops were cracked and bumpy and looked more like brownies! I was determined to get them right, so I took a macaron baking class in person – and it changed EVERYTHING! 

The trickiest part? Mixing the dry and wet ingredients together. Under mix = too dry and cracked. Over mix = dense and heavy. But now I know exactly what the batter should look like!

Pro tip: Age your egg whites for 24-48 hours before making the meringue – this helps them get to the perfect consistency!

Perfect for Valentine's Day, gift-giving, special occasions, or anytime you want elegant French macarons at home! 🇫🇷
