Whisk together melted butter, sugar, maple syrup, vanilla extract, and salt together in a bowl. Add the flour and combine.
Pour dough into greased pan and even it out in the pan with a spatula. Place in the oven for 15-20 minutes or until edges are turning golden brown.
For the Lemon Filling
After 10 minutes of the crust cooking, to a saucepan add lemon zest, lemon juice, coconut cream, sugar, lemon extract, vanilla extract, and salt. Turn heat on medium and whisk together until well combined and all the sugar as dissolved.
While constantly whisking, pour in cornstarch and quickly work to dissolve at the powder. Whisk until gravy starts to thicken and coats the back of a spoon/spatula. Don't overheat or it will get too thick.
Remove cookie base from the oven and adding the lemon mixture over top and spread into an even layer carefully with a spatula. Place back in the oven and allow to cook for another 15 minutes.
Pull out and allow to cool completely on a baking rack. Once cooled add powdered sugar over top using a sifter to serve immediately. Or store in fridge until ready to serve and do not add powdered sugar until ready to serve.
