Preheat your oven to 325°F and lightly grease a small 4-inch springform pan or oven-safe ramekin.
In a small bowl, combine the almond flour and melted coconut oil until it reaches a sandy consistency.
Press the almond mixture firmly into the bottom of the prepared pan to form an even, compact crust.
In a medium bowl, whisk together the Greek yogurt, protein powder, egg, and maple syrup until the batter is completely smooth and free of lumps.
Pour the cheesecake batter over the crust and smooth the top with a spatula.
Bake for 25 to 30 minutes, or until the edges are set but the center still has a slight, soft jiggle.
Remove from the oven and let it cool to room temperature, then refrigerate for at least 2 hours to set fully.
While the cheesecake chills, gently warm the mixed berries in a small saucepan over medium heat until they release their juices and thicken into a light sauce.
Top the chilled cheesecake with the juicy berry compote just before serving.
