Preheat oven to 350ºF and line a 9x13 baking sheet with parchment paper. In a large mixing bowl, combine ingredients for crust. Mix using a hand mixer or food processor until combined and crumbly.
Press dough into baking sheet. Bake for 10-12 minutes until crust is just a light golden brown.
While crust bakes, combine ingredients (except coconut flakes) for topping. Whisk until well combined.
Pour topping onto crust and sprinkle with coconut flakes. Return to oven 20 minutes or until coconut is lightly toasted.
Allow bars to cool at room temperature for 1 hour before slicing.
Notes
Tip: Paired with a hot cup of tea or coffee, I have found that these lemon bars are equally delicious served warm or chilled!
