Chocolate pound cake is a moist and velvety old fashioned chocolate pound cake, tooped with a deliciously decadent chocolate glaze for even more rich chocolate flavor.
Beat in the butter and sugars together until light and fluffy. This takes about 2 - 3 minutes at medium speed. On low beat in the eggs and vanilla extract one at a time, waiting until the previous ingredient is just combined before adding the next. Mix until well combined.
By hand or on the lowest mixing speed, sift the dry ingredients into the wet alternating with the brewed espresso and sour cream until the batter is just combined.
Evenly scoop the chocolate pound cake batter into the prepared bundt pan. Bake the pound cake bundt for 60 - 70 minutes. Cool the cake in the loaf pan for 10 minutes. Remove the cake from the pan to cool to room temperature.
