Crunchy cinnamon-flavored Life Cereal makes a delicious adult-friendly marshmallow crispy treat that kids will love too.
In about ten minutes you can make a batch of these delicious Life Cereal Bars to serve as an afternoon snack, after-dinner dessert, or bedtime treat.
This recipe is quick and easy to make and it’s a great snack for adults and kids alike. I bet Mikey would love them!
Look at all those layers of crispy Life Cereal held together with gooey marshmallows.
The squares of multigrain cereal stay nice and crunchy when blended with marshmallows and butter and they make really unique-looking cereal treats.
To make these treats we started with our BEST rice krispie treat recipe. Our original recipe calls for a ratio of 4 2/3 cups of cereal to 10 ounces of marshmallows.
We had to add more cereal because the Life Cereal squares are much larger than the tiny puffs of Rice Krispies Cereal.
The Life Cereal treats were too sticky with less cereal. 7 cups of cereal made perfectly chewy yet crispy treats.
We always suggest you use European-style salted butter to give your treats the best flavor and this time I added a dash of cinnamon to really enhance the flavor of the Life Cereal in these treats.

how to make Life Cereal Bars
you will need:
- You can use original multi-grain Life Cereal, or the cinnamon, vanilla, or chocolate varieties. If you use the other flavors, you can eliminate the cinnamon from the recipe.
- You’ll need 10 ounces of marshmallows.
- Always use the freshest marshmallows you have on hand. Fresh marshmallows make more delicately chewy treats.
- While different brands of marshmallows weigh slightly differently, you can usually use 40 regular-size OR 6 cups of mini marshmallows.
- Use a scale or the measurement on the bag as a guide.
- We have found that salted European-style salted butter provides the best flavor in our cereal treats recipes. You’ll be amazed at the difference good butter will make in this recipe.
- We recommend using KeriGold or President Butter. Kroger Private Selection French-style Butter is great too.
TOOLS YOU’LL NEED:
- 9-inch or 8-inch square baking pan
- butter or cooking spray to grease your pan (I prefer the flavor of butter, but the non-stick spray works too.)

Let’s make some Life Cereal Bars…
step one: prep your equipment
- Grease a large mixing bowl, your square 8-inch or 9-inch pan, and a silicone spatula with softened butter or spray with baking spray.
- Pour a 13-ounce box (about 7 cups) Life Cereal into the bowl.
step two: melt the butter and marshmallows
- Cut 4 tablespoons of European-style salted butter into 4 pieces.
- Place in a medium saucepan and set over low heat.
- Using low heat is important. It will allow your marshmallows to melt slowly and not overheat.
- If you overheat your marshmallows, the sugars in the marshmallows will begin to caramelize so when you blend them with the cereal they will produce hard treats instead of chewy treats.
- Allow the butter to begin melting, then stir in 10 ounces of marshmallows.
- I prefer using mini marshmallows as they melt quickly but you can use traditional large marshmallows as well.
- Just be sure to stir them often, so they don’t overheat.
- Continue to heat over low heat, stirring often, until about 75% of the marshmallows have melted.
- Then remove the pan from the heat and stir the marshmallows vigorously, smashing them as needed, until melted.
- By taking the pan off the stove at this point, you will ensure your marshmallows don’t overheat and stay nice and soft.
- It may take a minute of stirring before all the marshmallows melt. Just keep stirring and smashing. You’ll thank me when you have delicately chewy treats that are easy to eat.
- If using, stir in 1 teaspoon cinnamon.
- I highly recommend using cinnamon if you are making your Life Cereal bars using original Life Cereal. You can skip it if using Cinnamon Life Cereal.
alternate microwave method:
- In a large, microwave-safe bowl, place 4 tablespoons of salted butter and 10 ounces of marshmallows.
- Microwave on high for 1 minute then remove and stir vigorously, using the residual heat to fully melt the marshmallows.
- Once again, you don’t want to overheat the marshmallows as this causes your cereal treats to be too hard.
- You need to use a large mixing bowl when melting the marshmallows in the microwave as the marshmallows will puff up a lot.
- If needed, you may microwave for additional 15-second intervals, stirring vigorously until melted.
- Stir in the cinnamon.
step three: mix everything together
- Pour the melted marshmallow mixture over the Life Cereal in the bowl.
- Stir gently until all of the cereal is coated evenly.
step four: spread into pan
- Spread the cereal treat mixture into the greased pan and gently press it into an even layer.
- If you press down too forcefully, you will break all the squares of cereal and create hard treats.
- Just press gently until you get the mixture to spread into an even layer.
- Let cool at room temperature for about 1 hour.
- Cut into squares.
