Step 1: Preheat oven to 275 degrees F. Grease and flour a 9x13 inch pan (I just use my Pan Release (recipe posted on this site).
Step 2: In a bowl combine the flour with baking soda and salt. Set aside.
Step 3: In a large bowl using an electric mixer at medium speed cream the butter with both sugars until light and fluffy. Beat in the eggs one at a time. Mix in applesauce and vanilla until combined. Beat in the flour mixture alternately with the buttermilk. Using a spatula or wooden spoon stir in banana mixture and poppy seeds until JUST combined. Pour batter into prepared pan.
Step 4: Bake in preheated oven for 1 hour, or until a toothpick inserted into the center of the cake comes out clean. Remove from oven then IMMEDIATELY place the cake into freezer for 1 hour. (This makes the cake very moist -- make sure not to sit the cake on any frozen food).
Step 5: Frost cooled cake with cream cheese frosting.
