Preheat oven to 350 degrees F (180 degrees C).
Grind Walnut (1/2 cup) and Pistachios (1/2 cup) in a food processor until desired texture is achieved. Add in Butter (2 tablespoon) , Ground Cinnamon (1/2 tablespoon), Honey (2 tablespoon) & Salt (1 pinch), pulse to combine with nuts.
On a floured surface, roll out Puff Pastry (1) into a slightly larger rectangle & cut out 12 squares.
Taking one square of puff pastry at a time, slightly stretch it with your hands into a square & place into the well of a muffin pan. Repeat with all squares.
Evenly add nut filling to each well of the muffin pan & then bake baklava in the oven for 15-20 minutes, until nicely golden, but without over browning the nut filling.
While baklava bakes, add Water (3 tablespoon) to Honey (1/3 cup) & stir until thoroughly combined.
When baklava is done baking, immediately remove the baklava pieces from the muffin pan & onto a serving platter.
Drizzle 1 tablespoon of honey syrup over each piece of baklava while still hot & then serve. Enjoy!
