These chocolate rice Krispies treats are rich, gooey, and loaded with chocolate flavor that takes classic marshmallow squares to the next level. With cocoa powder and chocolate chips swirled into melted marshmallows and butter, then mixed with crispy cocoa rice cereal, these bars set up soft and chewy with deep chocolate taste in every bite. They're easy to make in one pot and perfect for parties, bake sales, or any time you want a fun, nostalgic dessert that's a bit more chocolate-forward than the original.

The classic American rice krispies treat is something that is simple, quick, and easy to make. My nieces and nephews love making the gooey marshmallow treats. A few weeks back we decided to test out a chocolate version. I started off by analyzing my brown butter rice krispies treat recipe and built this recipe from there.
This recipe calls for both cocoa powder and chocolate chips for an intense chocolate flavor! I use this combo in my chocolate rice pudding recipe too!
Why Two Marshmallow Additions Matter
A couple notes on the ingredients:
- Mini Marshmallows. You'll need to divide the marshmallows as you will add them at two different times, after testing I found this is the best way to guarantee a gooey RKT . Don't miss my chocolate marshmallow cookie recipe- so good!
- Cocoa Powder. Since the cocoa powder does not need to react with baking soda or baking powder like it does in my chocolate cake recipe, you can use natural cocoa powder or Dutch-process cocoa powder. Just make sure it's unsweetened cocoa powder. My preference is Dutch-processed cocoa! Adding the cocoa powder helps give an enhance
- Chocolate Chips. I like to use whatever I have on hand- sometimes it's milk chocolate chips others semi-sweet chocolate chips.
- Cocoa Rice Krispies. Now since we are using melted chocolate and cocoa powder there is a lot of chocolate flavor going but I also like to use cocoa rice Krispies! You could use normal rice Krispie cereal in a pinch!

Melt, Mix, Set, Slice








To cut them I use a sharp knife, I sometimes coat the knife in cooking spray to help them easily cut through the gooey marshmallow.
I also find it easier to remove the rice Krispy block out of the pan and put it on a cutting board then cut the bars. Some people like to line the pan with parchment paper for easy removal but I find it easy to remove the one large piece and cut it.

They're chock a block full of delicious chocolate flavor, they are soft, gooey, and downright scrumptious!

Seriously Chocolatey Rice Krispies Treats
These chocolate rice Krispies treats are rich, gooey, and loaded with chocolate flavor that takes classic marshmallow squares to the next level. With cocoa powder and chocolate chips swirled into melted marshmallows and butter, then mixed with crispy cocoa rice cereal, these bars set up soft and chewy with deep chocolate taste in every bite. They're easy to make in one pot and perfect for parties, bake sales, or any time you want a fun, nostalgic dessert that's a bit more chocolate-forward than the original.
- Total Time: 1 hour 20 minutes
- Yield: 20 Bars 1x
Ingredients
- 6oz Salted Butter
- 16oz Mini Marshmallows, divided
- ⅓ cup Cocoa Powder
- 1 ¼ cup Chocolate Chips
- 8.5oz (8 Cups) Cocoa Rice Krispies
Instructions
- Place 10oz marshmallows in a large bowl and leave the rest in the bag and your Cocoa Rice Krispies in another large bowl set aside. Grease a 9X13 pan with non-stick spray.
- In a large pot over medium heat add the butter and cook for a few minutes, stirring frequently until just melted. Add the 10oz of marshmallows to butter, stirring until melted.
- Once the majority of your marshmallows have melted add your chocolate chips and cocoa powder. Mix until fully melted then add the cocoa rice cereal and remaining marshmallows.
- Continue mixing until every rice cereal is coated, you will still have chunks of marshmallows- thanks to the ones you just added. Pour into the prepared pan. And using a spatula press down evenly. Cover with plastic wrap and let cool for an hour before cutting.
Notes
Freezing: Once the chocolate rice Krispies are cooled and cut wrap them individually in plastic wrap then store them in a freezer-safe container for up to one month. You want them "double-wrapped" to help prevent freezer burn and keep the flavor strong. When you want to serve them let them thaw at room temperature for 30 minutes.

These are sooo good! When I was making them, my son kept eating them while they were warm, safe to say we almost didn't even get to the bars LOL

I haven't made this yet. But curious as to if you have this where the ounces are converted to other measurements? Like cups, Tablespoons, and teaspoons etc.
Elizabeth Waterson says
Hi JP, thanks for reaching out. If you press the toggle between the M/US button on the recipe card it shows metric vs us measurements. Please let me know if that helps and if you try the recipe would love to know what you think!

Help! I really want to make this, but is the chocolate chip gram unit really 280? The reason I'm asking is that other sites show chocolate chips weighing in a 170g per cup.
Thank you. (This looks really yummy.)
