These crispy, chewy and colorful rice krispie treats made with green sour apple marshmallows are a fun and delicious twist on a classic finger food treat.  

Sour Apple Rice Krispie Treats

Marshmallow krispie treats are the best. 

They’re comfort food, finger food, super easy to make, have a little salt (in the butter), sweet (from the marshmallow), and crunch (from the cereal).  The perfect combination.

Marshmallow krispie treats can be fun to make too because cereal comes in so many pretty and vibrant colors.

In this recipe, the krispie treats are made with rice krispies cereal with “spring colors” which has 2 additional colors in it, a light blue (similar to turquoise), and light green (similiar to a light lime color).

Here are more marshmallow krispie treat recipes you may like “Easter Krispie Treats“, “Captain Crunch and Pretzel Marshmallow Krispie Treats” and “Captain Crunch and Froot Loop Marshmallow Krispie Treats“.

To add some sparkle, these krispie treats are topped with candy sugar crystals (sprinkles) that come pretty close to matching the blue and green colors in the cereal. 

It kind of looks like jewels on top of the krispie treats and adds a nice crispiness to each bite.

I haven’t mentioned the best part yet, it’s the sour apple marshmallows

I found these at walmart and they actually taste like sour apple candy and are the perfect color to match the light green in the cereal and candy sprinkles.

Sour Apple Rice Krispie Treats

As an option, the top of each of these krispie treats can be decorated with half of one of the sour apple marshmallows.  

Since these marshmallows are in the shape of an apple, decorating the krispie treat is a nice touch.  

A dollop of marshmallow creme can be used on the back of the marshmallow so it will stick on the krispie treat.

Since an entire package of sour apple marshmallows is used to make the krispie treats, there aren’t any leftover for decorating so you would just need to get an extra package of them.  

These krispie treats are really good

The sour apple flavor is just right, not too strong or overbearing.

Let’s check out the ingredients.
