Colorful, sweet, and easy to make fruity pebble rice krispie treats will be a hit wherever you serve them! These treats take minutes to assemble, are easy to transport, and require only 6 ingredients.
Line a 9×9 pan with parchment paper with an overhang for easy removal. Spray parchment paper with cooking spray. Set aside.
Grab your biggest NONSTICK pot and melt the butter over low heat. Once the butter is completely melted, add in ALL BUT 2 and 1/2 cups of the marshmallows. Stir constantly, keeping the heat on low, until the marshmallows are completely melted.
As soon as the marshmallows are just melted, remove the pot from the heat. Stir in the salt and vanilla extract. Next stir in the rice krispie cereal and fruity pebbles very gently. Lastly, stir in the reserved 2 and 1/2 cups marshmallows. Stir until combined.
Pour the mixture into lined and prepared pan. Lightly spritz your hands with cooking spray and gently (do not press hard/compact or you'll get hard bars) press the bars in evenly into the pan.
Allow the bars to cool and set up before using the overhang to pull the bars out and cut them into squares. Bars best enjoyed same day.
Note 1: You can use ALL fruity pebbles instead, but I found it to be a little too sweet. Plain krispies aren't sweetened while fruity pebbles are sweetened.
