In a small mixing bowl, combine crushed Oatmeal Raisin cookies and melted butter. Press mixture onto the bottom of a 9-inch springform pan. Pre-bake the crust for 8 minutes. Set aside to cool.
In a large mixing bowl, beat the cream cheese and sugar until light and fluffy. Add the coconut milk, chia seeds, and vanilla extract. Mix until well combined. Add eggs one at a time, beating well after each addition.
Pour the filling over the cooled crust.
Bake for about 50 minutes or until the center is almost set.
Cool for 15 minutes before carefully running a knife around the edge of the pan to loosen the cheesecake.
Cool completely at room temperature, then cover and chill in the refrigerator for at least two hours.
To make the topping, combine berries and sugar in a pan and heat until sugar dissolves. Let it cool.
When ready to serve, remove cheesecake from the pan and decorate the top with whipped cream and berries mixture.
