👩‍🍳 How to Make Cocoa Krispies Treats

These step-by-step instructions are accompanied by detailed photos for enhanced clarity and guidance.

Step 1. Spray a Baking Dish

The first step is to spray a 9×13-inch baking dish or baking pan with cooking spray, or you can also line the dish or pan with aluminum foil, or spread some butter on the pan if you prefer. Then, set the baking dish or pan aside for now.

Note: We are using a baking dish, but there is no baking done in this recipe. You can use any 9×13-inch pan you have.

Step 2. Melt the Butter

Secondly, put 4 tablespoons of butter in a saucepan. Melt butter over medium low heat until it is just about melted.

Step 3. Add the Marshmallows

Keep the heat on medium-low and add 16 ounces of mini marshmallows to the saucepan together with the melted butter.

Note: You can use the big marshmallows, a 16-ounce bag, about 64 marshmallows, with no problem, just as long as it is equivalent to this recipe. The only difference I see in using mini marshmallows is they melt faster. I mean they taste the same, right? A marshmallow is a marshmallow, after all. 🙂

Step 4. Melt the Marshmallows and Butter

Then, melt the marshmallows with the butter until the mixture is completely melted. Remember to keep stirring while it is melting. After that, turn the heat off.

Step 5. Add the Cocoa Krispies

After turning the heat off, slowly add all 7 cups of Cocoa Krispies cereal to the saucepan together with the marshmallow and butter mixture. Adding the cereal all at once can be difficult to mix it up.

Step 6. Mix the Cocoa Krispies and the Marshmallow Mixture

Next, using a spatula or spoon, stir the Cocoa Krispies cereal together with the marshmallow mixture until all the Cocoa Krispies cereal is coated with melted butter and marshmallow cream. Be careful not to smash up the cereal.

Step 7. Spread the Cocoa Krispie Mixture in the Dish

With a spatula or spoon, spread the Cocoa Krispie mixture evenly into the baking dish, or you can use your hands to spread it around. It is easier to spread if you put a little bit of butter on your hands, then spread the mixture around.

When done spreading the Krispie mixture around in the dish, gently flatten the mixture down just a tiny bit. Do not press too hard. I like my Krispie treats ooey gooey and soft, but not falling apart. So that’s why you press ever so lightly, but just firm enough so they won’t fall apart when it’s time to eat them.

Note: Remember, the harder you pack them, the harder they are to eat.

Step 8. Let the Cocoa Krispie Treats Set

Allow the Krispie Treats to set for about an hour to cool. If the Krispie treats aren’t cooled, they will fall apart when you try to cut them (in step 9), and also fall apart when you eat them.

Step 9. Cut the Cocoa Krispie Treats

After the Cocoa Krispie treats have cooled, cut them into squares, serve, and enjoy!

Note: It is best when the Krispie treats are served the same day. They are good for just a couple of days in an airtight container on the countertop, but the longer they sit, the harder they get.

So eat ’em up within that time, or you can freeze them for up to about two months in the freezer if you choose to, however, it is not recommended since the texture will change and the Cocoa Krispie treats can become soggy when thawed.

❓ FAQs

Can You Freeze Cocoa Krispie Treats?

Yes, to freeze Cocoa Rice Krispie treats, place them in layers, separated by wax paper, in an airtight container. When doing this, you can freeze them for up to 6 weeks. To thaw, let the Krispie treats sit on the countertop at room temperature for 15 minutes before serving. But be aware that they can become soggy after thawing.

Why is My Cocoa Krispie Treats Soggy?

Using too little rice cereal will make your treats soggy, and using too much will make it hard to keep the rice cereal stuck together.

Is There Anything Else I Can Add to Cocoa Krispie Treats?

Yes, you can make chocolate Rice Krispies treats by adding about 2 to 3 tablespoons of cocoa powder together with the melted butter and marshmallow.

Or how about 1/2 of a cup of chocolate chips, or 2 to 3 tablespoons of peanut butter, or both? Peanut butter and chocolate chips sound amazing to add to Cocoa Krispies treats.

To make peanut butter Cocoa Rice Krispies, you can add peanut butter to the butter marshmallow mixture while it is melting on the stove or it can be spread on top when the Cocoa Krispies are cooling.

The chocolate chips can be added to the butter marshmallow mixture while it is cooking on the stove or added after the marshmallow cream has melted. You don’t necessarily need to have the chocolate chips melt completely in this mixture. Some will melt while the mixture is still hot, but if some don’t melt, that’s even better yet, if you know what I mean. You can also spread some melted chocolate chips on top of the Krispie treats.
