Line an 8x8 inch baking pan with parchment paper and preheat the oven to 350F.
Mix the gluten free graham cracker crumbs and melted butter in a bowl, press firmly into the bottom of the pan, and bake for 10 minutes, then let it cool.
In a large bowl, whisk the full fat coconut milk and instant vanilla pudding mix until smooth and thickened.
In a separate bowl, whip the heavy whipping cream until stiff peaks form, then gently fold the whipped cream and shredded coconut into the pudding mixture.
Spread the creamy filling over the cooled crust, cover, and chill in the refrigerator for at least 3 hours before slicing.
