In a large bowl, combine oats, puffed rice cereal and slivered almonds.
In a medium saucepan over medium heat, cook maple syrup, coconut oil, cinnamon and salt until coconut oil is melted, about 3 minutes.
Add mashed bananas in the maple syrup mixture. Mix well.
Pour banana mixture over oat mixture and mix well.
Line two baking sheets with parchment paper and divide mixture between the two.
Bake in top and bottom thirds of oven, switching and rotating baking sheets halfway through and stirring twice, until crisp and golden, 30 to 35 minutes (watch closely after 25 minutes).
Let cool and break up in large chumps.
