Alpha-Bits Marshmallow Cereal Bars

Blend alphabet-shaped cereal with melted butter and marshmallows to create fun cereal treats for an after-school snack.

Making Alpha-Bits Marshmallow Cereal Bars is so easy using just 3 ingredients. Kids of all ages will love making and eating these treats. 

Making marshmallow cereal treats using a variety of kid’s cereals has been so much fun. 

I always start by using our Best Rice Krispie Treat recipe as a guide, but when using cereal with larger pieces, I always need to adjust the ratio of cereal to melted marshmallows. 

Starting with the best-tasting European-style salted butter and fresh marshmallows is the key to making these Alpha-Bits cereal treats taste great!

Our original recipe calls for a ratio of 4 2/3 cups of cereal to 10 ounces of marshmallows.

We had to add 8 cups of the Alpha-Bits Cereal because the pieces are much larger than the tiny puffs of Rice Krispies Cereal. 

The treats are still nice and chewy but they aren’t overly sticky.

how to make Alpha-Bits Crispy Treats

you will need:

ALPHA-BITS CEREAL

• Alphabet-shaped, frosted multi-grain cereal made from whole-grain oat and corn flour. 

MARSHMALLOWS

• 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. 

BUTTER

• We have found that 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: 

• 9×13-inch baking pan 
• large mixing bowl
• silicone spatula or large mixing spoon
• butter or cooking spray to grease your pan, bowl, and spatula (I prefer the flavor of butter, but the non-stick spray works too.)

Let’s make some Alpha-Bits Cereal Bars…

step one: prep your equipment 

• Grease a large mixing bowl, a 9×13-inch pan, and a silicone spatula with softened butter or spray with baking spray.
• Pour  8 cups of Alpha-Bits Cereal into the bowl.  

step two: melt the butter and marshmallows 

stovetop method:

1. Cut 4 tablespoons of European-style salted butter into 4 pieces. 
2. 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. 
3. 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. 
4. Continue to heat over low heat, stirring often, until about 75% of the marshmallows have melted.
5. 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. 

alternate microwave method:

1. In a large, microwave-safe bowl, place 4 tablespoons of salted butter and 10 ounces of marshmallows.
2. 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. 
3. If needed, you may microwave for additional 15-second intervals, stirring vigorously until melted. 

step three: mix everything together 

1. Pour the melted marshmallow mixture over the Alpha-Bits Cereal in the bowl.
2. Stir gently until all of the cereal is coated evenly.

step four: spread into pan

1. Spread the cereal treat mixture into the greased pan and gently press it into an even layer.
2. Let the pan of treats cool at room temperature for about 1 hour. 
3. Remove from the pan and cut into squares.
