Chill the Pan: Place your metal loaf pan in the freezer before you begin.
Separate the Cream: Open the chilled can of coconut cream and scoop the thick, hardened cream into your blender. Reserve any leftover watery liquid at the bottom for smoothies.
Blend the Base: Add the almond milk, maple syrup, vanilla extract, sea salt, and almond butter (if using) to the blender. Blend on high speed for 60 to 90 seconds until the mixture is completely smooth and slightly frothy.
Fold in Mix-Ins: Pour the mixture into your chilled loaf pan. If using mix-ins, gently fold them into the liquid base with a spatula.
The Contact-Wrap Trick: Press a sheet of plastic wrap directly onto the surface of the liquid. This prevents freezer burn and ice crystals from forming on top.
Freeze: Freeze undisturbed for at least 6 hours, or overnight.
Soften and Serve: Remove from the freezer and let it sit at room temperature for 5 to 10 minutes before scooping.
