Preheat oven to 350 degrees Fahrenheit.
In a large mixing bowl, whisk together flour, cornstarch, baking powder, salt, turmeric, and lemon zest.
In a separate mixing bowl, whisk together lemon juice, granulated sugar, oil, almond milk, applesauce, vanilla, and lemon extract.
Pour wet ingredients into bowl of dry ingredients, and whisk (or use mixer) everything together until just combined.
Oil and flour a large bundt pan (needs to hold 10-15 cups of batter).
Pour batter into bundt pan and bake at 350 degrees Fahrenheit for 50-55 minutes, or until a toothpick comes out clean.
Once baked, remove cake from oven and allow to rest in bundt pan for about 5 minutes before turning pan over onto rack, plate, or platter to cool.
