3tablespoons(40grams)vegetable oil(sunflower, canola, or other)
1teaspoon(5grams)baking powder
1lemon(the grated zest)
LEMON FILLING
2cups(500grams)plant milk(almond, oat, rice, soy, or other)

CRUST
Preheat the oven to 350F or 180C. Line the baking pan with parchmentpaper, letting some of the parchment paper go over the edges of the pan so that it will be easier to remove the pie from the pan.
To a bowl, add the grated zest of one lemon, sugar, water, and oil. Mix with a spatula to combine.
Sift in the flour and bakingpowder and mix with a spatula till the flour absorbs the liquids.
With your hands, knead the dough for just a minute. You can do this in the bowl.
Transfer the dough into the baking pan and flatten it and compress it with your hands to create a compact base layer of dough.
Make some holes with a fork, then bake in the oven at 350F or 180C for 15 minutes. Keep the oven turned on once baked.
LEMON CURD
To a medium saucepan, add the peel of one lemon (not the grated zest, the peel),plant milk, sugar, cornstarch and a pinch of turmeric to add a light yellow colour.Stir with a whisk till there are no lumps.
Squeeze the lemons to produce ⅓ cups (80 grams) of lemon juice. Filter it with a sieve and set it aside (you don't want small bits of lemon in the curd).
Bring the saucepan onto medium heat and stir the liquid with a whisk until it thickens.
Add the lemon juice and keep stirring with the whisk to incorporate the lemon juice in it until it's fully absorbed by the custard.
LEMON BARS
Let the crust cool down for 10 minutes, then pour the lemon curd onto the baked crust and level it off with a spatula.
Bake in the oven at 350F or 180C for another 15 minutes.
Let cool down for about an hour before taking it out of the shape.Cut into squares and serve. Right before serving you can sprinkle with powdered sugar, but keep in mind that it will dissolve after a seconds.
