Preheat oven to 350°F
Grease a 10-cup bundt pan with nonstick spray.
Whisk together flour, baking soda, baking powder, salt, cinnamon, and nutmeg.
With an electric mixer, in a separate mixing bowl, beat together the sugar, eggs, oil, yogurt, and vanilla.
Gradually add the flour mixture into the yogurt mixture, continue to mix on medium low until well incorporated.
Pour the batter into the prepared bundt pan, smooth the top, then bake the cake for 45 to 55 minutes, or until a toothpick inserted into the center comes out clean and the cake has begun to pull away from the sides of the pan.
Take the cake out of the oven and let the cake cool for 10 minutes, then carefully invert it onto a cooling rack.
Cool completely before adding the topping
