Preheat the oven to 160 degrees Celsius.
Blend the cottage cheese, Greek yoghurt, cacao, egg, maple syrup, corn starch and vanilla essence until smooth.
Line an oven-safe ramekin with parchment paper to prevent sticking, then pour in the batter.
Bake for about 40-50 minutes (middle should still be jiggly and sides more solid!)
For the topping, add the raspberries and chia seeds to a microwave-safe dish.
Heat in 30-second intervals, mashing with a fork each time, until the berries are soft and have a jam-like consistency.
Let the mixture cool to allow it to thicken.
Once the cheesecake has cooled slightly, spread the raspberry jam on top.
Refrigerate for at least 8 hours or overnight—this step is essential, as it tastes best when fully chilled!
