cake batter rice krispie treats

I came across this recipe over at kaitlin's blog and it really caught my attention. These look super yummy and i cannot wait to make them.

Ingredients:
3 Tablespoons Butter or Margarine (I always use margarine in mine, as I think butter makes them way too rich)
1 10 oz. Package of Regular Marshmallows or 4 Cups Miniature Marshmallows
6 Cup Rice Krispies
1/3 Cup White Cake Mix
1/3 Cup Rainbow Sprinkles

Directions:
Melt butter or margarine in a large sauce pan, add marshmallows and constantly stir until they are melted, then add in your cake mix and stir until it is dissolved in the marshmallows. Add your Rice Krispies and your sprinkles and mix until all of the cereal is evenly coated in marshmallow. Transfer mixture into a greased casserole dish and let cool before cutting.
