You can substitute with the same amount of allulose or 1:1 stevia. Mix in two pinches of salt, 6 drops of vanilla oil (combine all except for the nuts and chocolate).
Add 10g of crushed mixed nuts - 1.5 tablespoons (20g) of sugar-free chocolate chips (can be substituted with dark chocolate, preferably 80% or higher), and mix well.
Shape into cups (make them round and press down the center slightly) and freeze for 10 minutes.
Air fry at 150°C (302°F) for 5 minutes, then bake at 160°C (320°F) for another 5 minutes. Let cool completely before eating. *Do not remove immediately from the air fryer or they may crumble; let cool before removing!
