Grease and flour a bundt pan. I always just use Pam baking spray to coat my bundt pan with and my cakes always come out perfectly.
In a bowl, beat the the sugars and eggs together until light. Then blend in the applesauce, oil and vanilla until smooth.
Add in the remaining cake ingredients and fold in just until combined.
Pour batter into the prepared bundt pan and bake at 350 degrees for 45 minutes or until a toothpick inserted in the center comes out clean.
Allow cake to cool for 10 minutes then invert and allow to cool completely.
Once the cake is cooled, then make the glaze. Add butter, brown sugar, cream, and salt to a sauce pan and cook over medium heat. Stir until it comes to a boil. Boil for 1 minute and remove from heat.
Add the powdered sugar to the pan and whisk together until smooth. You may have to put a little muscle into it, but it will get smooth.
Place a piece of foil under the a cooling rack with the cake on it. The pour the glaze over the cake doing your best to evenly coat the entire cake. Makes 12 servings.
