Make the baklava nut mixture. Use the food processor or a knife to chop all the nuts into a coarse mixture and add to a bowl. (You can use more of the walnuts, pecans, or pistachios instead of almond flour). Add in the salt, lime zest, cinnamon (if using) and mix in. Add in the maple syrup and mix to make a slightly sticky mixture.
Make the oat mixture. Heat the non-dairy milk so that it is hot. You can heat it in a saucepan or microwave it. In a bowl, add the oats, chia seeds, maple syrup, vanilla, yogurt, lime zest, and ¾ cup of the heated non-dairy milk. Mix until well combined, then fold ¼ to ⅓ of the nut mixture into the overnight oats mixture. Let it sit for 5 to 10 minutes for the oats to absorb some of the liquid. If the oat mixture becomes too thick, add in a little bit more milk, 1 to 2 tablespoons at a time.
Prep your mason jars or other jars/cups/bowls that you are planning to serve the overnight oats in, and transfer the oat mixture to the jars. Top with the remaining nut mixture. You can also add some hemp seeds to the topping. Add some sliced oranges or other fruits of choice, like strawberries, sliced banana or blueberries, and then store these jars in the fridge for up to four days.
