Preheat oven to 350 F. In a bowl, beat together the egg, egg yolk, and coconut sugar until creamy (the mixture should almost double in size). Add the vanilla, coconut oil, and almond butter and continue to beat until well incorporated.
1 egg, 1 egg yolk, ⅔ cup coconut sugar, 1 teaspoon vanilla, ¼ cup coconut oil, ¼ cup almond butter
Fold in the almond flour and baking soda with a rubber spatula until no flour clumps remain. Add the chocolate chips and continue to fold into the batter.
2 cups almond flour, ½ teaspoon baking soda, ¾ cup dairy-free chocolate chips
Spoon batter into a greased 9-inch springform pan**. Use the bottom of a measuring cup to press the batter into the sides of the pan. Add a few more chocolate chips on top if desired. Bake in oven for 20 - 22 minutes until golden brown. Let cool completely.
Remove the cookie cake from the spring form pan by first slipping a small knife around the sides to ensure the cake isn't stuck. Then release the "buckle" to release the cake from the pan.
Prepare the Chocolate Ganache Frosting (or vegan buttercream, see notes section below). Transfer the icing into an icing bag fitted with a star-shaped tip. Pie stars along the edges of the cookie cake and dust with sprinkles if desired.
