Chocolate and peanut butter are a dominating flavor combination but with Dilly Bars, you add marshmallows & Rice Krispies to create a flavor bomb that ultimately reigns supreme!
I’m pretty sure chocolate and peanut butter is the world’s most famously paired flavors (or at least in my world!). But when you add marshmallows into the mix with Rice Krispies, you create a flavor bomb that’s ready for world domination with just 5 ingredients, 1 bowl, and a microwave!
Growing up, my grandma used to make these chocolate peanut butter Rice Krispies treats for me because she knew how much I loved chocolate and peanut butter. At the time, she called them Dilly Bars.
I have no idea. I did a bit of research and can’t find any Dilly Bars similar to these. Other Dilly Bar recipes that pop up simply result in recipes for Rice Krispie treats that have been frosted with a thin layer of chocolate. And trust me, those recipes ain’t got nothin’ on my grandma’s Dilly Bars!
I remember eating Dilly Bars all summer long while visiting my grandparent’s cottage on Lake Ontario. My favorite way to eat them (and still is!) is cold, right out of the refrigerator. I remember running straight out of the lake and eating 2 or 3 of these at a time with my hands still wet. They really did make the best post-swim snack!
I absolutely love these chocolate peanut butter Rice Krispie treats because unlike traditional Rice Krispie treats, Dilly Bars have the texture of a bar cookie — probably because of all the chocolate melted into them! Rather than being gooey and sticky like traditional treats, these are fudgy, full of peanutty crunch, and melt in your mouth delicious!
The best part! Dilly Bars can be made with just 5 ingredients and mixed up in 1 bowl in the microwave in less than 20-minutes! And if you have a dishwasher, it will make the chocolatey, marshmallow clean-up that much easier. #winning (is that still a thing?
The only downside of Dilly Bars is the hour-long wait to eat them while they chill in the ‘fridge. As long as you can hold off an hour, I promise you’ll be delivered a chocolatey, peanutty flavor bomb!
Feel free to lick the bowl while you wait out their chill time, I sure did!
- ¼ cup unsalted butter
- 2 cups semisweet chocolate chips
- 1½ cups extra crunchy peanut butter*
- 16 ounces marshmallows, large or small
- 4-5 cups Rice Krispie cereal
- ½ teaspoon sea salt**
- Using the cut ¼ cup of butter, lightly grease the bottom, edges, and corners of a 9x13 pan then it set aside
- In a large mixing bowl (that fits in your microwave!) melt the butter remaining butter, ~1 minute on high
- Into the melted butter, add the chocolate chips
- Place the melted butter and chocolate chips into the microwave and heat for 20-seconds on power level 7-8***
- Remove the bowl and stir vigorously for 10 seconds
- Repeat the 20-second heat followed by stirring until your chocolate chips are melted (~2 minutes total)
- When most of the chocolate is melted, you should be able to stir the remaining chips until they too melt into the rest of the chocolate
- Once the butter and chocolate are fully melted, stir in the peanut butter.
- On top of the chocolate peanut butter mixture, add all of the marshmallows.
- Heat the marshmallows in the microwave for 20-seconds on power level 7-8
- Remove the bowl and stir vigorously for 10 seconds.
- Repeat the 20-second heat followed by stirring until your marshmallows are melted (~2 minutes)
- Add in 4 cups Rice Krispie cereal (and salt if using) and stir until combined -- you may have to use your hands and massage the mixture to ensure all of the cereal is fully coated. If the mixture looks a little wet, add in the additional cup of Rice Krispie cereal (I prefer 4.5 cups when making these)
- Turn the mixture out into the prepared pan
- Using a spatula, smooth the mixture into the corners of the pans, ensuring an even, flat layer across the bars
- Refrigerate the bars for at least 1 hour
- Let bars sit at room temperature for 5 minutes before slicing
- Dilly Bars will keep in the refrigerator, covered for up to one week
** If you use unsalted peanut butter, then I suggest adding salt to your Dilly Bars. Or if you simply enjoy saltier desserts, add this in, you won't be disappointed!
*** Using a high power setting may risk burning the chocolate, it's better to use a lower setting and go slower than melt them too quickly and burn the chocolate.
