Preheat your oven to 325°F (165°C) and lightly grease a 4-inch springform pan or small oven-safe ramekin.
In a small bowl, stir together the almond flour and melted coconut oil until it reaches a sandy consistency, then press it firmly into the bottom of your prepared pan.
In a separate mixing bowl, whisk the Greek yogurt, vanilla protein powder, egg white, and maple syrup until the batter is completely smooth and free of lumps.
Pour the cheesecake mixture over the almond crust and tap the pan on the counter to release any air bubbles.
Bake for 25 to 30 minutes until the edges are firm and the center has a slight, custard-like jiggle.
While the cheesecake bakes, place the mixed berries in a small saucepan over medium heat and simmer for 5-8 minutes until they burst and form a thick sauce.
Remove the cheesecake from the oven and let it cool to room temperature, then refrigerate for at least 2 hours to set.
Top the chilled cheesecake with the berry compote before serving.
