- Chopped peanuts
- Sugar-free chocolate chips
- Coconut
- Sea salt
if desired.
Lightly press toppings into the surface.
Step 6: Chill
Place the pan in the refrigerator.

2 hours
or until fully set.
For faster results, freeze for:
45–60 minutes
What Happens During Chilling?
The fats solidify and create:
- Firm texture
