Preheat the oven to 325 degrees F. Spray a 10-inch standard sized bundt pan with baking spray. Use a pastry brush to brush the spray evenly on the pan, set aside. Or coat with vegetable shortening and sprinkle with flour moving your pan around making sure the flour coats the whole band.
Add the flour, sugar, butter, eggs, buttermilk, and vanilla into the bowl of a stand mixer fitted with the paddle attachment
Mix on low speed for about 2 minutes until the ingredients start to combine.
Place the mixer on medium speed and mix for 2 more minutes until smooth and fully combined
Add the chocolate chips and with spatula or spoon, stir them in until incorporated.
Add the batter to the prepared bundt pan and smooth out the top.
Place in the oven and bake for 80-90 minutes, until a toothpick inserted into the center comes out clean. If you notice the pound cake browning too quickly, you can tent with foil (we usually do this halfway through baking).
Remove from the oven and let cool in the pan for 10 minutes, then turn out the pound cake onto a wire wrap and let it cool completely.
Transfer bundt cake onto your serving platter and dust with powdered sugar if using, slice and serve.
