Preheat oven to 350℉.
Grease and line a 13"x9" inch cake pan.
In a large bowl, whisk together flour, sugar, cornstarch, baking soda, and salt.
Cut the butter into the flour mixture until it forms crumbly pieces.
Mix in the egg and almond extract until just combined.
Press about ¾ of the dough into the prepared pan, pressing firmly.
Bake in preheated oven for 10 minutes.
Remove from oven and spread cherry pie filling evenly over the crust.
Sprinkle remaining crust mixture over the cherry pie filling.
Bake for 20-25 minutes, until golden on top and cherries are bubbling.
Allow to cool in the pan.
Once cooled, remove from pan and drizzle the glaze over the top.
Cut into squares for serving.
