For the ice cream base, combine the softened ice cream, whipped topping, and cinnamon in a large bowl. Use a stand mixer, hand beater, or blender to combine. Spread ice cream mixture evenly in a 9 x 13 inch pan and place in the freezer.
For the topping: In a large skillet over medium heat, melt butter. Add cornflakes and sugar and fry for about 5 minutes, stirring occasionally. Remove from heat and set aside to cool.
If you're freezing this ahead of time, layer the cornflake mixture on the ice cream as soon as it's cool then freeze for 2 hours or overnight.
If you want the topping to be warm, wait to prepare the cornflake topping until 30 minutes before you're ready to serve, then pull the pan from the freezer, top with warm topping, and serve immediately.
Either way, cut the dessert into squares and serve with honey or chocolate sauce.
For a fancier presentation, scoop ice cream mixture into individual serving bowls or glasses then sprinkle with cornflake mixture.
