Preheat your oven and line your baking dish if desired. Mix the graham crumbs together with the melted butter until well combined, then press the mixture firmly into the bottom of the dish to form a crust layer. Bake for about 8–9 minutes to set the crust, then remove and let it cool slightly.
In a large bowl, beat the softened light cream cheese until smooth. Add Greek yogurt, honey (or maple syrup), the egg, and vanilla extract, mixing until creamy. Stir in the shredded coconut, then pour the mixture over the baked crust, smoothing the top for even baking.
Bake the cheesecake bars in the pre-heated oven for about 20 minutes until the edges are set but the center still has a slight jiggle. Remove from the oven and while it’s still warm, toast the topping coconut in a small pan until lightly golden and then sprinkle this toasted coconut on top. Chill the bars in the refrigerator for at least 4 hours (or ideally overnight) before slicing into squares.
