Preheat oven to 350 degrees. Grease a 10” bundt pan.
In a small bowl, combine the topping ingredients and set aside.
In a medium bowl, whisk together the flour, baking powder, baking soda and salt.
In a large bowl, cream together the butter and sugar at medium speed until fluffy. Then add the eggs, one at a time, beating until light and creamy.
Add dry ingredients alternately with the Greek yogurt and vanilla to the creamed mixture, stirring with a large spoon.
Spread half the batter in the prepared bundt pan, spoon 3/4 of the topping over batter. Cover with the remaining batter and then top with the remaining topping.
Bake for approximately 50 to 55 minutes or until inserted toothpick comes out clean. Cool slightly then serve.
