To make the chocolate ganache, heat the cream in a small saucepan until hot (do not boil). Add the chopped chocolate and stir until smooth. Set aside to cool.
In a large bowl, add the cooled chocolate ganache, melted butter, Greek yogurt, eggs, and sugar. Beat until smooth. Add the flour mixture and beat to combine.
Then add coffee and milk, beat until smooth, and stir in chocolate chips. Spoon into the prepared bundt pan and bake for approximately 45–50 minutes; test with a toothpick for doneness.
