Adjust the oven rack to the middle of the oven and preheat it to 350˚ F.
Add the flour, sifted cocoa powder, salt, baking soda and baking powder to a medium bowl. Set aside.
Add the butter to the bowl of a standing mixer and mix on medium-high for about one minute.
Scrape down the standing mixer bowl, and add the granulated and brown sugars to the butter. Mix on medium-high for 3-4 minutes until light and fluffy.
Add one egg at a time, fully incorporating the egg before adding the next. This will be about 20-30 seconds on medium low after each egg addition. Scrape down the mixing bowl before adding in the vanilla bean paste.
Turn the standing mixer to low, and add about half of the sour cream and then half of the dry ingredients. Add the remaining sour cream and then dry ingredients. Mix until just combined.
Remove the bowl from the standing mixer and pour in the hot coffee or espresso. Use a sturdy spatula to mix in the coffee with a few stirs.
Briefly mix in the Chocolate Chips and make a final turn of the batter to make sure all the of the ingredients are incorporated.
Spray a 10-15 cup Bundt pan generously with baking spray. Transfer the batter into the pan. Smoothe top of the batter with a spatula and give the pan a good bang on the counter to eliminate any air pockets.
Bake for 45-50 minutes. The cake is done when you press the top and it springs back, and when a toothpick comes out with a few crumbs clinging to it.
Let the cake cool for 10 minutes (set a timer). The edges of the cake will start to pull away from the pan while it cools. After 10 minutes, invert the bundt onto a wire rack and lift off the pan. If using a nonstick Bundt pan and it was well greased, the pan should easily release the cake. Let it continue to cool for 1-2 hours before adding glaze.
