In a food processor/blender, add the oats, dates, tapioca flour, coconut oil, baking powder, and salt. Blend for a couple of minutes until well combined.
Take a pan with a loose bottom and brush it with oil. Add the oat mixture and start pressing on it, spreading the crust on the walls of the pan (see video instructions below). Make some holes with a fork in the crust.
In a preheated oven (175 C / 350 F), add the crust and bake it for 15-20 minutes.
Meanwhile, in the same food processor, add the tofu, maple syrup, coconut oil, lemon zest, lemon juice, salt, and vanilla paste/extract. Blend, blend, blend. Taste the filling and see if you want it lemonier. If so, add more lemon zest.
When the crust is ready, take it out of the oven. Pour the filling into the crust and spread evenly.
Bake at 160 C / 320 F for about 30 minutes.
Let it cool, remove the “walls” of the pan and enjoy!
