USE a 6-7” nonstick springform pan. Cut a parchment paper circle for the bottom using the bottom of the pan as a guide and line the bottom of the pan with the parchment circle. If you do not have a pan that small, a plastic storage container or bowl of roughly that size can be used.
FOR THE CRUST, combine the almond flour, shredded coconut, cocoa powder, swerve, optional stevia, and melted butter in a small bowl. Mix until well combined and press into the bottom of the prepared pan. Place the crust in the freezer until ready to fill.
FOR THE FILLING, steam the cauliflower in the microwave or on the stovetop for about 5 minutes, until tender. Allow to cool completely OR Instant pot instructions: manual high pressure for 5 minutes.
COMBINE the cooled cauliflower, chilled coconut milk, Swerve, peppermint extract, and spinach* in a high-speed blender or food processor and blend until smooth and creamy.
STIR in about 2/3 of the chopped chocolate or cocoa nibs and pour over the crust. Sprinkle the remaining chopped chocolate/cocoa nibs over the top of the cake and return to the freezer for at least 5 hours, preferably overnight.
TO SERVE, carefully lift the cake from the pan/mold and slice into 6 pieces. If the cake has been frozen overnight, allow to sit at room temperature for about 5-10 minutes prior to slicing. (Tip: To ease in slicing, run a sharp knife under hot water, wipe dry, slice, and repeat.) Recall that for the leaner version of the P3 menu for yourself you will cut your slice into half once again and eat just one half of your slice.
