Preheat the oven to 350 degrees F. Spray a 9x13 inch baking dish with nonstick spray.

Stir the flour, sugar and salt together in a large bowl. Add the melted butter and stir until a shortbread-like dough comes together. I even use my hands to bring it together. Press half of the dough into the bottom of the dish.

In another bowl, whisk together the eggs, half and half, sugar, vanilla, cinnamon, salt and cornstarch. Gently fold in in the strawberries. 

Pour the mixture over top of the crust. Crumble the rest of the dough over top of the strawberry mixture. Bake for 40 to 45 minutes, until the bars are set and no long jiggly. Cool completely before slicing into squares!
