about these spooky chocolate peanut butter rice krispie treats
These particular chocolate peanut butter rice krispies treats remind me of my childhood. There are so many rice krispie treats variations out there, but this has to be my favorite!
No, these aren’t something that my mom made every year (we are more of a buckeye kinda family). However they were something that my best friend’s mom made back in elementary school. And I LOVED them.
You get crunchy, sweet, salty, and gooey all in the same bite. Plus they are no-bake and they are totally delicious. I mean the peanut butter chocolate combo is kinda hard to beat, am I right?
Obviously you can make these treats anytime of year, but I thought it would be fun to give them a little spooky twist! It’s so easy to cut these bars into whatever shape you like, and even easier to make them festive for the upcoming spooky holiday.
butter – unsalted butter is key here! Salted butter will throw off the flavor of the treats.
peanut butter – I recommend using smooth creamy peanut butter. Chunky peanut butter and natural peanut butter are not recommended (see my notes below for more details on that!).
cereal – you can use name brand rice krispie cereal for this recipe, or whatever other brand you prefer!
chocolate chips – I used semi-sweet chocolate chips, but you can use milk chocolate or even dark chocolate if you prfer.
oil – all you need is vegetable oil for this recipe.
this recipe’s must haves
To make this recipe, you only need a handful of basic tools! First you will need a large saucepan to make the melted marshmallow mixture.
Finally, a 9×13-inch baking pan. Don’t forget spooky cookie cutters for cutting the treats into fun shapes!
here’s how to make chocolate peanut butter rice krispie treats
In a large saucepan over low heat, add butter, peanut butter, and marshmallows. Stir gently until the mixture is melted. Be careful not to burn the mixture.
Grease a large bowl with cooking spray and add rice krispie cereal. Pour over melted marshmallow mixture and stir together with a spatula (I like to spray mine with cooking spray to avoid a sticky mess!).
Once combined, press the mixture into the bottom of a greased 9×13-inch pan. Set aside.
Melt chocolate in a medium-sized microwave-safe bowl. I put mine in the microwave for 45-second intervals, stirring in between each, until melted.
Once melted, stir in vegetable oil and pour over the bars. Smooth with a spatula.
Place pan in the refrigerator and let harden for 30 minutes until the chocolate is set, but not hardened.
Cut into shapes and decorate as desired. Store in an airtight container at room temperature.
tips for success
don’t store in the fridge. If you store these chocolate peanut butter rice krispie treats in the refrigerator, they will harden too much and be difficult to eat!
too hard or too soft. Don’t let your bars turn out too hard or too soft. Melt the marshmallows together slowly over a lower heat setting so the marshmallows don’t burn! If they burn, that causes the treats to turn out too hard. To make sure your treats aren’t too soft, be sure to firmly pack the treat base into the pan!
can I use natural or chunky peanut butter?
I don’t recommend using natural peanut butter because it could separate and the bars won’t harden.
You can use chunky peanut butter, but I personally feel like it ruins the texture of the bars! It’s up to you though.
how do I decorate these?
I like to use spooky cookie cutters to cut out shapes for these treats! I made mummies out of the circle treats by drizzling white chocolate in random strips over the treats and placing candy eyes on top.
To make the ghosts, I cut out the shape, then added dots of melted white chocolate and pressed candy eyes on top.
Get as creative as you’d like with these treats! You can also simply cut them into squares and drizzle with white chocolate, adding candy eyes all over to make them monster eyeball treats.
how long do these rice krispie treats last?
Chocolate peanut butter rice krispie treats can be stored for up to 3 days at room temperature. Keep them in an airtight container!
