Blend the cherries and chia seeds together. Add to a small pot, and cook over low heat for 5-7 minutes. Pay attention so it doesn't burn!
Allow to cool down, the texture should resemble a jam.
While that's happening, add the pistachios, oats and maple syrup to a food processor. Process until consistent and scoop into a bowl.
Press the pistachio crust evenly to 4, 4oz jars, layer with the cherry jam, and top with whipped cream. Finish off by topping the whipped cream with leftover jam and crushed pistachios. Enjoy!
