Let 1 stick of butter soften at room temperature overnight, or for a few hours.
Preheat oven to 350°F (180°C).
In a saucepan, combine chopped dates, water, and baking soda. Bring to a boil over medium heat, then set aside to cool for about 10minutes. In a large bowl, cream together softened butter and sugar with a hand mixer, until fluffy.
Beat in eggs, 1 at a time, until integrated.
Add Greek yogurt and vanilla extract and beat to integrate.
In a separate bowl, whisk together flour, baking powder, and salt.
Transfer boiled date mixture to a food processor or blender and blend with cinnamon until smooth.
Gradually add blended date mixture and flour mixture into the creamed butter mixture, alternating. Beat well with a hand mixer as you go, until combined.
Grease a 12-cup Bundt pan with cooking spray or butter and dust with flour.
Pour batter into Bundt pan and tap to remove any air bubbles. Bake 1 hour, until a toothpick or skewer comes out clean.
Allow to cool for 20 minutes before removing from pan.
Dust with powdered sugar before slicing. Serve and enjoy!
Cover date cake with plastic wrap or store in an airtight container at room temperature for 3-5 days.
