Preheat the oven to 350°F
Place the graham crackers in a zip-top bag, remove the air, and seal. Crush the crackers into fine crumbs using a mallet or rolling pin
Transfer the crumbs to a bowl and mix with the melted butter or coconut oil until the mixture is slightly sticky
Grease a springform pan. Press the graham cracker mixture evenly into the bottom of the pan and halfway up the sides, pressing firmly to set the crust
In a large bowl, combine the Greek yogurt, cream cheese, eggs, maple syrup, and salt
Mix with a hand mixer until smooth. A blender can also be used if you don't have a mixer
Pour the cheesecake batter into the crust and smooth the top
Bake for 45-50 minutes, until set
Remove from the oven and allow the cheesecake to cool completely
Once cooled, wrap the pan and refrigerate overnight
Before serving, top with raspberry jam or fresh berries
