Mix the crust ingredients in a food processor then press into the bottom of a springform pan and bake for 10 min. (I like to wrap Reynolds wrap around the outside of my pan to prevent any butter leaks).
Cream cheeses together then add sugar and melted chocolate and Greek yogurt.
Then add in eggs and vanilla mix well.
Add cacao powder, salt, zest and orange juice. Mix well then pour into crust.
Bake at 350 for about 45 min. Or until set.
Drizzle a little melted dark chocolate on top just for looks! Enjoy!!
