Preheat your freezer to prepare for the ice cream layer. Seriously, this is crucial.
In a mixing bowl, combine brewed coffee, protein powder, almond flour, cocoa powder, sweetener, baking powder, vanilla extract, and salt. Mix well until smooth.
Pour the batter into a greased 9-inch round cake pan and spread it evenly.
Freeze for about 1 hour or until the cake layer is firm. Patience is a virtue, my friend!
After freezing, layer the ice cream over the chilled cake, smoothing it out as needed.
Sprinkle chocolate chips on top if you're feeling indulgent, and freeze again for at least 2 hours.
Slice and serve once set. Enjoy every guilt-free bite!
