Why These Strawberry Banana Cheerios Rice Krispie Squares Are a Must-Try

These fruity cereal squares aren’t just fun — they offer a slightly more nourishing twist on the classic Rice Krispies treat. Using Cheerios that are made with whole grain oats, this also makes them gluten-free.

1. Made with Whole Grain Oats

Cheerios are made primarily from whole grain oats, which means they naturally contain more fiber than traditional puffed rice cereal. Whole grains help support digestion, keep little tummies fuller longer, and provide steady energy — especially helpful for school days and active afternoons.

2. Naturally Contains More Fiber

Compared to classic rice cereal, oat-based cereals typically contain more dietary fiber. Even a small bump in fiber can help balance out a sweet treat and make it feel more satisfying. Each 40g serving contains about 3g of Fiber.

3. Strawberry Banana Cheerios Offer a Unique Flavor

Strawberry Banana Cheerios tend to be lower in sugar than many brightly colored breakfast cereals. When combined with marshmallows and butter, the overall sweetness is still balanced without becoming overpowering.

4. Provides Iron & B Vitamins

Many Cheerios varieties are fortified with iron and B vitamins, which support energy production and overall development in children. While this is still a treat, it carries a little more nutritional value than traditional rice cereal squares.

5. A Treat with Staying Power

Because oats digest more slowly than refined rice cereal, these squares may feel more satisfying and less like a quick sugar spike. That makes them a better option for lunchboxes or mid-afternoon snack breaks.

Unlike traditional treats, these Strawberry Banana Cheerios Rice Krispie Squares (Easy No-Bake Treat and only Simple 4-Ingredient Treat) are a fun and fruity alternative that kids will love.

While these Strawberry Banana Cheerios Rice Krispie Squares are still very much a sweet treat, using an oat-based cereal adds a little more substance compared to traditional puffed rice squares. They’re not meant to replace a wholesome meal, but they can be a fun, homemade option that feels just a bit more balanced. Around here, we love finding small ways to make classic favourites a touch more nourishing — without taking away the joy.

Ingredients You’ll Need (Just 4 Simple Pantry Staples)

Before you get started, you will want to gather your supplies and ingredients. Here is a full list of everything you will need:

Supplies

• 1 large stainless steel pot
• 1 9×13 baking dish greased with butter
• Large measuring cup (8 cup)
• wooden spoon – These are my favorite wooden utensils, the flat-bottomed one is great for scraping the bottom of pots

Ingredients

• 1 400g bag of big marshmallows
• 8 cups of Strawberry Banana Cheerios (one 317g box)
• 1/4 cup of butter
• 2 tbsp of sweetened condensed milk

How to Make Strawberry Banana Cheerios Rice Krispies Square

1. Prepare the Pan

The first thing you must do is grease the 9×13 baking dish with butter or your favorite oil.

2. Melt the Butter

Place the large pot on the stove, add the butter, and melt it over medium heat, making sure not to let it burn.

3. Add the Marshmallow

Once the butter has melted, add the marshmellows stirring frequently using a wooden spoon. Allow the marshmallow to melt 90% before turning off the heat. Add the 2 tbsp of sweetened condensed milk and stir to combine.

4. Add in the Strawberry Banana Cheerios

Next, add the strawberry Banana Cheerios, all 8 cups at one time. Mix it until fully combined.

5. Pour into Baking Dish

Carefully add the Strawberry Banana Cheerios Rice Krispie Squares (Easy No-Bake Treat and only Simple 4-Ingredient Treat) mix into the greased baking dish. Be sure to press it into each corner, making it as even as possible. These Strawberry Banana Cheerios Rice Krispie Squares (Easy No-Bake Treat and only Simple 4-Ingredient Treat) are best when chilled for a bit before serving.

6. Let it Set

Cover and the Strawberry Banana Cheerios Rice Krispie Squares (Easy No-Bake Treat and only Simple 4-Ingredient Treat) set on the counter for a few hours or overnight is best. Once set, cut into desired sizes and enjoy.

How to Store These Strawberry Banana Cheerios Rice Krispie Squares (Easy No-Bake Treat and only Simple 4-Ingredient Treat)

Proper storage of these Strawberry Banana Cheerios Rice Krispie Squares (Easy No-Bake Treat and only Simple 4-Ingredient Treat) makes all the difference in keeping them soft and chewy. Room temperature is the best in an airtight container.

Refrigeration isn’t recommended. The fridge tends to dry out marshmallow squares and can make them firm and less chewy. If your kitchen runs very warm in the summer, a cooler pantry space is better than the refrigerator.

Freezing them is a great option. I often make a double batch and freeze half for busy homeschool days — having a homemade treat ready to pull out makes afternoons feel just a little easier. Here’s how I freeze them:

• Wrap individual squares tightly in parchment or plastic wrap.
• Store in a freezer-safe container or bag.
• Freeze for up to 6 weeks.

Let them thaw at room temperature for about 20–30 minutes before serving. They’ll return to that soft, gooey texture.

More Variations on Strawberry Banana Cheerios Rice Krispie Squares

What Makes Strawberry Banana Cheerios Rice Krispie Squares So Special?

One of the best things about cereal marshmallow squares is how easy they are to customize. Once the marshmallow mixture is melted, you can quickly stir in a few extras to create a completely new flavour. Here are a few fun ideas to try:

These delightful Strawberry Banana Cheerios Rice Krispie Squares (Easy No-Bake Treat and only Simple 4-Ingredient Treat) are perfect for sharing at parties or as an after-school snack!

Add a Little Chocolate

Stir in a handful of white chocolate chips after the mixture has cooled slightly, right before you put it in your baking dish. The chocolate will soften just enough to create little pockets of sweetness throughout the squares.

Mix in Dried Fruit

Add a small handful of chopped dried strawberries, banana chips, or even dried cranberries to boost the fruity flavour and add a bit of texture and a pop of color.

Sprinkle with Coconut

Unsweetened shredded coconut adds a light tropical flavour that works beautifully with the strawberry banana cereal.

Drizzle with White Chocolate

Once the squares have cooled, melt a little white chocolate and drizzle it over the top. This adds a pretty finish and pairs especially well with the strawberry banana flavour.

Make Them Extra Marshmallowy

If your family loves gooey squares as we do, simply stir in an extra handful of mini marshmallows right at the end before pressing the mixture into the pan. This is the best way to get extra gooey squares.

Frequently Asked Questions

Can I use a different flavor of Cheerios?

Yes! This recipe works well with many Cheerios flavours. Honey Nut Cheerios, Apple Cinnamon Cheerios, or even plain Cheerios will all create delicious cereal squares. Each one gives the bars a slightly different flavour while keeping the same chewy marshmallow texture.

Can I use regular Cheerios instead of Strawberry Banana Cheerios?

Absolutely. Plain Cheerios will still work perfectly in this recipe. If you use plain Cheerios, you can mix in a small handful of dried fruit like chopped dried strawberries or banana chips to add a fruity flavour.

Why are my cereal squares hard instead of soft?

This usually happens when the marshmallows are melted over too much heat. Marshmallows should be melted slowly over low heat and removed from the stove as soon as they are smooth. Overheating can cause the squares to become firm once they cool.

How do I keep my Rice Krispie-style squares soft?

The key is storing them in an airtight container at room temperature. Keeping air out prevents the marshmallow from drying out and helps the squares stay soft and chewy.

Can I make these cereal squares dairy-free?

Yes. Simply substitute the butter with a dairy-free butter alternative or coconut oil and omit the sweetened condensed milk. The texture and flavour will still work well with the marshmallow mixture.

Are these cereal squares good for lunchboxes?

Yes! These squares hold together well and make a fun homemade lunchbox treat. Once cooled and cut, they can easily be wrapped individually or stored in a container for quick snacks throughout the week.

Can I double this recipe?

I don’t recommend doubling this recipe, as it can be very hard to get the marshmallows to melt evenly. It also becomes very hard to mix in Cheerios when the recipe is doubled. If you need a double batch, I would recommend doing it in two batches.
