Get a baking tray and line it with parchment paper. Set it aside.
In a large bowl, mix together maple syrup, cashew butter, vanilla extract, and melted coconut oil until you achieve a creamy, smooth consistency, and the cashew butter has slightly thinned down.
Slowly add the puffed brown rice crispies, gently folding them into the mixture until everything is well combined. Feel free to add more rice crispies if you desire extra crunch.
Now, it's time to roll the mixture into bite-sized balls of yumminess. Take 1 tablespoon of the mixture and roll it in the palm of your hands, then place it on the lined baking tray. Repeat this process until you've used up all the mixture.
TIP: Keep a small bowl of warm water nearby while rolling the balls to prevent your hands and fingers from getting too sticky from the mixture.
Now, place the tray in the freezer to set for 15-20 minutes or until it hardens. NOTE: You could try coating the balls with the melted white baking chips immediately, but there's a chance they may fall apart. To prevent this from happening, it's best to place them in the freezer.
