Preheat your oven to 325°F (163°C).
In a small bowl, combine the almond flour and melted coconut oil until it reaches a sandy consistency.
Press the almond flour mixture firmly into the bottom of a 4-inch springform pan or a large oven-safe ramekin to create the crust.
In a separate mixing bowl, whisk together the Greek yogurt, egg whites, and vanilla protein powder until the batter is completely smooth.
Pour the cheesecake batter over the prepared crust and smooth the top with a spatula.
Bake for 25 to 30 minutes until the edges are firm but the center still has a slight jiggle.
Remove from the oven and let it cool to room temperature, then refrigerate for at least 2 hours to set.
While the cheesecake chills, place the mixed berries in a small saucepan over medium heat.
Simmer the berries for 5 to 8 minutes, stirring occasionally, until they break down into a thick, syrupy compote.
Spoon the warm berry compote over the chilled cheesecake before serving.
