Line an 8×8 inch pan with parchment paper.
Add maple syrup, almond butter, vanilla extract, and salt to a bowl. Stir to combine.
Add the puffed cereal to the bowl and stir until the rice cereal is well-coated.
Spread the mixture in the pan and press down firmly with a spatula.
Melt the chocolate chips with the coconut oil in a saucepan and pour the melted chocolate over the almond butter cereal mixture. Spreading it evenly.
Put the pan in the fridge for about 30 minutes.
Cut into 9 bars (which works best with a large chopping knife) and enjoy! Store leftovers in an airtight container in the fridge.
