Put the cream in a bowl together with the allulose, and beat for a few minutes with an electric beater until it gains more consistency.
Add the cream cheese, Greek yoghurt, and coconut milk little by little, and beat until smooth.
Finish with the lemon juice, vanilla extract, and then the unfrozen blueberries.
Put in the freezer for 3 hours. Take out and decorate with blueberries! And done.
