Cream together butter, sugar and salt in a large bowl until fluffy.
Add the eggs, one at a time, mixing well after each.
Add vanilla, mix until thoroughly blended.
Gradually mix in flour.
Spread about 3 cups of the batter into a greased 15x10x1 baking pan. Reach the corners too..
Spread with pie filling.
Drop the rest of the batter by spoonfuls on top of filling. It won't cover completely..
Bake 30 minutes until lightly browned.
Cool for at least 15 minutes, preferably longer, then glaze.
To make the glaze, mix powdered sugar, vanilla and 2 tablespoons of milk.
Add more milk if necessary until the frosting is just thin enough that can drizzle it over the top. Using a spoon, lightly pour frosting over the pan of uncut cookies
After drizzling, let set before cutting. If you aren't plating it for serving right away, I suggest cutting into larger squares until you are ready to use. If freezing wrapping it snugly in plastic wrap, then stack in a ziplock bag and freeze.
