Preheat the oven to 350°F. Lightly coat bundt pan with cooking spray or vegetable shortening. Set aside.
Sift or whisk together the flour, pumpkin pie spice, salt, baking soda and baking powder. Set aside.
In the bowl of a stand mixer fitted with a paddle attachment or a large mixing bowl with an electronic hand mixer, cream the sugar, vanilla Greek yogurt and eggs. Add the pumpkin puree and vanilla, blend until just mixed.
Slowly add the dry ingredients to the wet ingredients. Do not over mix, this can result in your bread being tough.
Pour the cake batter into the greased bundt pan. Bake for 1 hour to 1 hour 15 minutes, or until it passes the toothpick test. If the top starts brown, loosely cover with a sheet of aluminum foil.
Remove the cake and allow it to cool for 10 minutes. Place a serving dish over the top and flip. Knock the top (bottom of the bundt pan) with a knife to loosen the cake inside.
Glaze:
After the cake has fully cooled, whisk together the powdered sugar with milk and cinnamon until smooth. You might need a little more powdered sugar or milk to make the mixture “drizzle-able”. Drizzle over the Pumpkin Pound Cake. Top with the pepitas while glaze is still tacky.
Slice and serve with a heaping scoop of vanilla ice cream and a cup of coffee.
