Coat the inside of a 9" x 13" baking dish with butter and set aside.
In a large Dutch oven pot, melt the butter on medium heat. Add the mini marshmallows and stir until the marshmallows are almost all melted. Turn the heat off and add the vanilla and coconut extract. Stir.
Add the Fruity Pebbles Cereal and mix until combined.
Pour the cereal mixture into the prepared baking dish. Using the back of a spoon, spread the mixture evenly into the pan.
Get your hands just a little wet or spray with nonstick cooking spray and gently pat down the Rice Krispies Treats. Cool until they hold their shape. Cut into 3" squares and enjoy!
