In a medium bowl combine the filling ingredients. Whisk until combined; set aside.
To prepare the batter:
Preheat oven to 350℉. Lightly grease a 9x5 inch loaf pan and set aside.
In a large mixing bowl whisk together the flour, salt, baking powder, baking soda and 1 cup of granulated sugar. Make a well in the center.
In a medium mixing bowl whisk the eggs until blended. Add the vanilla, milk and oil and whisk until combined. Pour the milk mixture into the flour mixture. Stir with a spoon or spatula until the dry ingredients are just moistened. The batter will be slightly thick.
Pour one-third of the batter into the prepared pan. Sprinkle half the filling over the batter. Carefully spoon half of the remaining batter over the filling. Sprinkle all remaining filling evenly over the batter. Finally, top with the last of the batter. Swirl the batter and filling together using a knife or skewer. Set aside allowing the cake to rest for 10 to 15 minutes before baking.
Bake the loaf cake at 350℉ for 55 to 63 minutes or until a toothpick or skewer inserted in the center comes out with no wet batter. Moist crumbs are okay!
Cool the cake in the pan for 20 minutes then transfer to a platter or wire rack. Serve slightly warm or at room temperature. Dust with powdered sugar or drizzle with the optional vanilla glaze.
To prepare the glaze:
Whisk the glaze ingredients together until smooth. Add more milk or powdered sugar to reach desired consistency. Drizzle over the warm cake, slice and serve.
