Preheat the oven to 325-degrees. Spray 2 large loaf pans, 9" x 5", with a cooking spray and line with a sheet of parchment paper, pressing into the bottom and edges of the pans.
Beat the butter on low speed until it becomes very creamy. Raise the speed to medium and continue beating the butter until it is very light and fluffy, looking much like whipped cream. Scrape down the sides of the mixing bowl to make certain all the butter is whipped thoroughly.
On medium speed, add the sugar, about ¼ cup at a time, allowing the sugar to blend into the butter before adding more. Once all the sugar has been blended into the butter, add the eggs one at a time, followed by the sour cream.
Using separate bowls, sift together the flour, baking soda, and kosher salt. Sift the dry ingredients three times. Don’t’ skip this step it does make a difference in the texture of your cake.
On low speed slowly add the dry ingredients to the batter, blending in about ⅓ cup at a time, beating just until the flour disappears. Add both the vanilla and almond extracts along with the Cognac, stirring into the batter on low speed.
Divide the batter evenly between two large loaf pans, which have been greased and floured. If the weather is humid you can also line with parchment paper, lightly grease and flour the parchment as well for a clean release from the pan.
Bake on the center rack of your oven at 325-degrees for about 60 to 65 minutes, or until the cakes are golden and they test done with a toothpick inserted in the center.
Let the cakes cool in the pans for about 15 minutes, then turn them out onto a wire rack to cool completely.
