Prepare the Crust:
In a large bowl, combine graham cracker crumbs, melted butter, and flour. Mix until the crumbs are evenly coated and the mixture starts to form.
Press the mixture into a greased 9×9-inch pan, forming an even base.
Bake at 275°F (135°C) for 5 minutes. Remove from the oven and let it cool.
Prepare the Topping:
In a medium bowl, mix together sweetened condensed milk, shredded coconut, and chopped pecans.
Spread the coconut mixture evenly over the cooled crust.
Bake the Bars:
Increase the oven temperature to 325°F (163°C) and bake the bars for 20-25 minutes or until the coconut topping turns golden brown.
Make the Lemon Icing:
In a medium bowl, beat together softened butter, heavy cream, and fresh lemon juice.
Gradually add icing sugar and beat until smooth and creamy. Add a few drops of pink food coloring to achieve the desired pale pink shade.
Finish the Bars:
Once the bars have cooled, spread the lemon icing over the top. Allow it to set for a few minutes.
Slice into squares and enjoy!
