Add all cheesecake ingredients to a blender and blend until completely smooth.
Pour the batter into a parchment-lined 6-inch round baking dish. Spoon about ¼ cup of the chopped pistachios over the top and gently swirl them into the batter.
Bake at 325°F (165°C) for 40–45 minutes, until the edges are set and the center still has a slight jiggle.
Transfer to the fridge and chill for at least 8 hours. Overnight is best for the perfect texture.
While the cheesecake chills, blend ¼ cup pistachios with ½ cup cottage cheese and 2 tablespoons maple syrup until smooth.
Spread the topping over the chilled cheesecake and finish with the remaining chopped pistachios.
Notes
The center should look slightly underdone when it comes out of the oven. It will fully set as it chills.
This recipe is designed for a 6-inch pan. Using a larger pan will thin the batter and change the bake time and texture.
For a less sweet version, reduce the sweetener slightly, but note that lower sugar can make the cheesecake firmer once chilled.
Swaps: To make this dairy-free, use dairy-free cottage cheese and yogurt alternatives.
