Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking pan to prevent sticking.

In a large mixing bowl, cream together the softened butter and sugar until light and fluffy. Beat in the eggs one at a time, then blend in the vanilla extract.

In a separate bowl, mix the flour and salt, then gradually add to the butter mixture until fully incorporated.

Spread 3 cups of the batter evenly across the bottom of the pan, then layer the cherry pie filling on top. Drop small clumps of the remaining batter over the cherry layer.

Bake for 35-40 minutes until the top is golden brown. A toothpick inserted in the center should come out clean.

Let the bars cool completely on a wire rack before adding the glaze.

Mix powdered sugar, milk, and vanilla extract to form a glaze. Drizzle over the cooled bars.

Let the glaze set, then slice into bars and enjoy!
