In a medium saucepan, melt two sticks of butter. Continue stirring the butter over medium heat until it starts to brown and smells nutty.
Add the marshmallows to the pan and melt them down while stirring together. In the beginning the marshmallows will look like they aren’t mixing together with the butter, but after about 5 minutes they will.
Add the sweetened condensed milk to the melted marshmallow mixture and stir together.
Remove from the heat and add the vanilla and blue food dye. Add as many drops as it takes to get your desired shade of blue.
Pour the mixture on top of the rice crispy cereal and mix together until all of them are completely coated.
Add ½ cup of the white chocolate chips, ¾ cup of the crumbled chocolate chip cookies and ¾ cup of the crumbled Oreos to the Rice Krispie mixture and stir together.
Coat a 9x11 inch pan with butter or cooking spray to prevent the Rice Krispie treats from sticking.
Pour the mixture into the pan and spread evenly. Sprinkle the remaining chocolate chips cookies, Oreos, and white chocolate chips on top of the pan and gently press into the Rice Krispies.
Cover the pan and let the treats rest for at least 20 minutes, then cut and enjoy.
Notes
● Store in an airtight container in the refrigerator, or take each Rice Krispie treat square and wrap individually in plastic wrap.
