Prepare the Cake: Follow the instructions on the cake mix box to bake your cake. Allow it to cool completely once finished.
Gather the Ice Cream: Let your vanilla ice cream sit at room temperature for about 10 minutes, making it easier to spread.
Layer the Ice Cream: Once your cake is cooled, cut it in half horizontally, and place one layer back in the pan. Spread an even layer of softened vanilla ice cream on top.
Add Crunch: Sprinkle crushed waffle cones and drizzle with hot fudge sauce over the ice cream layer.
Top and Chill: Place the second cake layer back on top, pressing down gently. Cover the entire cake with a layer of whipped cream, and freeze for at least 4 hours, or until firm.
Final Touches: Before serving, drizzle with hot fudge, add chopped nuts, and any other creative toppings you desire!
