Place fruit in a large mixing bowl and toss with cornstarch, white sugar, lemon extract, and lemon zest.
Pour the coated fruit mixture into the greased pie dish. Then in that same mixing bowl, add all of the dry ingredients: brown sugar, oats, flour, cinnamon, and salt.
Toss them together, and then pour in the MELTED coconut oil. Fold together until all dry ingredients are coated with the oil. It will be a crumble-like texture. Spread onto fruit.
Cover the fruit crisp with tin foil and bake for 25 minutes. Then another 20 minutes without foil. Top with ice cream and enjoy!
