The night before making your individual tiropita, make sure to remove your phyllo dough from the freezer. Allow thawing in the fridge.
In a large pot, heat 2 tbsp butter on medium heat for around 30 seconds.
Add the onions and saute until softened, about 4-5 minutes. Stir often to avoid burning.
Once the onions have softened, remove from the heat. Add them to a bowl with the crumbled feta, shredded graviera cheese, egg, cream, salt and pepper. Mix together to combine.
Preheat the oven to 375F and prepare 2 baking sheets with parchment paper.
Melt 1/2 cup butter and set it aside. Have it ready with a brush to gently coat your phyllo.
It is best to keep your phyllo dough moist, so I suggest laying it out flat then covering with a damp cloth.
Gently place one sheet of phyllo dough onto a large cutting board or flat surface. This is a very delicate ingredient, so be patient.
Using your brush, coat the whole thing with melted butter.
Scoop approximately 1 heaping tbsp of the filling 1 – 2 cm away from the edge of one strip.
Use a pizza cutter or knife to cut the layered phyllo dough into 4 long strips. Roll the phyllo dough directly over the filling to fully cover it.
Next complete a diagonal fold towards one side, to begin a triangle formation.
Continue this type of diagonal fold down the entire strip, making sure to alternate the sides of each fold.
Arrange onto the baking tray and lightly brush with any of the leftover melted butter (if there isn't any use olive oil). Top each with a pinch of sesame seeds.
Complete these steps until all of the filling is used.
Bake for 20 – 25 minutes, until golden brown and crisp. Drizzle with honey and sprinkle on some chili flakes if desired. Enjoy!

Notes
You can make and then freeze these so they're all prepped to be baked for a great make-ahead appetizer! Make the tiropita triangles (except for brushing butter on top of the triangles) and lay on a parchment paper lined baking sheet. Freeze fully on the baking sheet. Once fully frozen, transfer to freezer bag and freeze for up to one month.
To bake from frozen, preheat the oven to 375F. Lay the tiropita on parchment lined baking sheets. Brush the tops with melted butter or olive oil. Sprinkle sesame seeds on top and bake for 30-35 minutes until golden brown. Let them cool for a few minutes before serving topped with a drizzle of honey and chili flakes.
Graviera cheese can be found at most local Greek stores. In a pinch, you can substitute with gruyere cheese or parmesan cheese.
