Preheat the oven to 350°F (175°C).
In a medium bowl, combine the flour, sugar, and salt.
Stir in the melted butter and egg, mixing until combined.
Press the mixture into the bottom of a greased 8x8-inch baking pan to form the crust.
Bake the crust for 15 minutes, until lightly golden.
While the crust bakes, prepare the cherry filling.
In a medium bowl, combine the cherries, lemon juice, almond extract, cornstarch, and sugar.
Pour the cherry filling over the pre-baked crust, spreading it evenly.
Bake for an additional 25-30 minutes, until the filling is bubbly and the bars are slightly firm.
Allow the bars to cool completely in the pan before slicing and serving.
