Preheat your oven to 350°F (175°C). In a large mixing bowl, cream together butter and sugar until light and fluffy, about 3-5 minutes. Add eggs one at a time, mixing well until combined. Gradually incorporate flour until a smooth dough forms.

Press two-thirds of the dough into the bottom of a greased baking pan. Bake for 15 minutes or until edges are lightly golden and center is set.

Spread cherry pie filling evenly over the baked crust, leaving a small gap at the edges. Crumble the remaining dough on top.

Return the pan to the oven and bake for an additional 25 minutes, or until the topping is golden brown.

Remove from the oven and place on a wire rack to cool completely. Once cooled, slice into squares.
