Heat oven to 350 degrees. Line 1 large cookie sheet with cooking parchment paper.
Mix whoopie pie ingredients in a bowl until a stiff dough forms.
Add eggs, extra almond flour, and green food coloring. Beat with an electric mixer until well-blended. Scoop mixture into a decorating bag with fitted tip, or freezer bag with a small corner snipped off. Pipe the batter into 30 2-inch circles set 1 inch apart.
Bake 8 to 10 minutes until the cookies spring back when touched. Allow to cool completely before applying frosting.
While the cookies are cooling, make keto cream cheese frosting. In a medium bowl, beat cream cheese until smooth with an electric mixer on high. Add sweetener, butter, vanilla extract and beat until smooth and whipped. Refrigerate for 30 minutes to make it easier to work with before adding frosting to the pies.
Scoop the frosting into decorating bag or freezer bag with small corner snipped off. Pipe frosting between two cookies to make a complete whoopie pie.
