Preheat the oven to 350 degrees. Spray a bundt pan with cooking spray.
In a large bowl whisk together the flour, baking soda, baking powder and salt. Set aside.
In the bowl of a stand mixer, beat the butter and sugar on medium speed until light and fluffy, about 4 minutes.
Add in the eggs, one at a time, followed by the Greek yogurt and vanilla.
Slowly pour the flour mixture into the mixer and mix until just combined.
Pour half of the batter into the prepared bundt pan.
Divide the Nutella in half and drizzle ¾ of a cup on top of the batter. Top with the remaining batter.
Swirl batter with a knife.
Bake for 55 minutes or until a toothpick inserted in the center comes out clean.
Remove from the oven and let rest for 10 minutes before inverting the bundt pan over a plate.
Allow cake to cool completely.
Microwave remaining ¾ cup of Nutella for 1 minute or until it reaches a consistency where it can be easily drizzled.
Drizzle Nutella on top of the cake.
Slice and serve.
