Preheat your oven to 375°F (190°C). Line an 8x8 or 9x9 baking dish with parchment paper and spray with nonstick spray.

In a large mixing bowl, combine flour, sugar, baking powder, and salt. Mix in room temperature butter until it resembles coarse crumbs. Add egg and milk, stirring until combined.

Press about two-thirds of the dough into the bottom of the lined baking dish to form a crust.

Mash the fresh cherries until slightly chunky. Strain excess juice and mix with sugar and cornstarch. Layer over the crust.

Crumble the remaining dough over the cherry filling.

Bake for 32-36 minutes until golden brown on top.

Cool completely at room temperature for 2-3 hours before slicing.
