Stir until creamy and combined. It should have the texture of a frosty. You may add more soy milk if you prefer it thinner.
Stir in vanilla wafers and bananas.
Top with cool whip and a cherry.
Notes
*Note* You can add in more pudding if you prefer a sweeter, stronger banana taste. If you do that you will also need to increase the soymilk and ice cream as well. Otherwise, you run the risk of just have pudding. (Made that mistake a lot during my recipe testing)
