Melt coconut oil with cacao powder in small saucepan on low heat. Add maple syrup, vanilla, and a pinch of salt and mix well.
Add rice cereal to a bowl and then add the chocolate mixture and mix well so that the cereal is completely covered.
Line a loaf pan or a square baking pan with parchment paper. Pour in rice cereal and chocolate mixture and flatten into an even level.
Place in freezer for 20-30 minutes or until it is completely set.
Lift parchment paper out of pan and separate the bar from paper. Cut into bars (of your choice of size) and enjoy!
Keep in freezer or fridge until ready to serve.
Notes
Cut into 9 inch bars or even smaller bite sizes! Store in fridge or freezer - they can get a little melty when warm so best to keep refrigerated until serving.
