Healthy Lemon Bars

Preheat oven to 350°F (175°C) and lightly grease a 9x9-inch baking pan.

Combine flour, ½ cup butter, and ¼ cup brown sugar in a mixing bowl, then press the mixture evenly into the prepared pan to form the crust.

Bake the crust for 12 minutes until lightly golden, then remove from oven and let cool slightly.

In a large bowl, beat the 3 well-beaten eggs with 2 cups brown sugar and salt until well combined.

Fold the shredded coconut, raisins, lemon juice, and grated lemon rind into the egg mixture until evenly distributed, adding walnuts if desired.

Pour the lemon-coconut filling over the cooled crust, spreading it evenly across the surface.

Bake for 20-23 minutes until the filling is set and the top is light golden brown.

Remove from oven and allow to cool completely in the pan before cutting into bars and serving.
