Preheat your oven to 325°F (165°C) and lightly grease a 4-inch springform pan or oven-safe ramekin.
In a small bowl, mix the almond flour with a few drops of water until it reaches a sandy consistency, then press it firmly into the bottom of the pan to form a crust.
In a separate mixing bowl, whisk together the Greek yogurt, protein powder, whole egg, egg white, monk fruit sweetener, and vanilla extract until the batter is completely smooth and lump-free.
Pour the cheesecake batter over the almond crust and smooth the top with a spatula.
Bake for 25 to 30 minutes, or until the edges are set and the center has a slight, firm jiggle.
Remove from the oven and let it cool at room temperature for 30 minutes, then transfer to the refrigerator to chill for at least 2 hours.
While the cheesecake chills, place the mixed berries in a small saucepan over medium heat, stirring occasionally until they break down into a jammy sauce.
Spoon the warm berry compote over the chilled cheesecake just before serving.
