These copycat Starbucks rice crispy treats (also called marshmallow dream bars) are so easy to make at home. They are gooey, sweet, and loaded with yummy marshmallows.
Reserve about 5 ounces of the mini marshmallows and set aside.
In a medium pot, heat your butter over medium heat. Stir in 10 ounces of the mini marshmallows.
Gently stir, until everything is well melted.
Remove from heat and add the vanilla extract. Stir well.
In a large bowl add the cereal and then add the 5 ounces of mini marshmallows you reserved. Stir well. This will give the treats marshmallows throughout just like the originals.
Add the melted mixture to the cereal and additional mini marshmallows. Mix well.
Add the mixture to the 9 x 9 pan and let sit for about one hour.
