Mix oatmeal raisin cookie crumbs and melted butter in a bowl until well combined. Press onto the bottom of a greased 9-inch springform pan.
Bake for 10 minutes. Remove from oven and let cool while preparing the filling.
In a large mixing bowl, beat the softened cream cheese until smooth. Add the Greek yogurt, honey, and vanilla extract, and beat until well combined.
Add the eggs one at a time, beating after each addition. Pour filling into the cooled crust.
Bake for 35-40 minutes, until the cheesecake is set but still slightly jiggly in the center. Let cool to room temperature, then refrigerate for at least 2 hours or overnight.
To make the topping, whip the heavy cream until soft peaks form. Spread on top of the cheesecake and top with mixed fresh berries.
