Line a tin with parchment paper.
In a food processor place every dry ingredient for the base and process until well processed. Add wet ingredients and process until it resembles wet sand. Add more coconut oil if your mixture is too dry. ⠀
Press the base into the bottom of the tin.
In a high speed blender place every ingredient for the matcha cheesecake layer and blend well until smooth. Add more sweetener or lemon juice if you need. Layer the filling above the base and place bananas on the top. Freeze until set.
Take out the cake from the tin and cut with a warm knife
