Grease a 10-inch springform pan with butter. In a small bowl, combine nuts, butter, 1 tablespoon peanut butter, and honey. Press into the base of the pan in an even layer and transfer to freezer until firm, 10-15 minutes.
Combine coconut cream, frozen bananas, remaining ½ cup peanut butter, and ricotta in the bowl of a blender. Blend until smooth, scraping down the sides as necessary. Pour over crust. Drizzle with melted chocolate and transfer to freezer until entirely frozen, about 3 hours. Carefully remove springform mold, running a knife along the edges if necessary. If desired, sprinkle with additional chopped chocolate, cut into wedges, and serve.
