Atomic Fireball Cupcakes with Whipped Topping

1. Preheat oven to 350 degrees Fahrenheit and prepare 15-17 cupcake wrappers. Using a hand blender, in a small mixing bowl, beat the egg replacer powder, cream of tartar, 1/4 teaspoon salt, cornstarch and warm water until foamy, about 2-3 minutes. Set aside.
2. Using a hand blender, in a large mixing bowl, beat the oil and sugar well. Add coconut milk, vegan cream cheese, and vanilla extract; beat well. Add in the egg replacer mixture and beat well to incorporate.
3. Sift in all remaining dry ingredients (bread flour, all purpose flour, 1/2 teaspoon salt, baking soda, baking powder, ground cinnamon, and ground cayenne). Mix by hand until there are no lumps. The batter will be relatively thick, but should still be scoopable by spoon.
4. Add in lemon juice and mix by hand until incorporated. Scoop by spoon into prepared cupcake wrappers, filling about 2/3 full. Bake 20-22 minutes, or until a toothpick comes out clean.
These are a spicy kick in the mouth! They are just how I like them, and remind me in all the right ways of the candies they were replicating. If you think they might be too much for you, tone down the cinnamon and cayenne a little bit, and find out what works for you. The whipped topping cools them down significantly.
Bread flour has a very high gluten strength and protein content of compared to other flours, and I used it here to compensate somewhat for the structural integrity that comes from the whipped egg whites in the original recipe. Cake flour, alternately, has the least amount of protein or gluten among flours. So, you can try swapping this out and let us know how it works for you, but the recipe as is gave me a really nice consistency cupcake.
For a topping, I was originally going to go for something marshmallow-y like the original. I decided against it, and I went with a very slightly modified version of Isa Chandra Moskowitz's "Rad Whip," which you can find on her blog, here: http://www.theppk.com/2011/04/rad-whip/ . I modified it by adding 2 additional tablespoons coconut oil. Her recipe gives a phenomenal "Cool Whip" texture, and I wanted something just a little firmer since I wanted it to stay on the cupcakes as a stand-alone topping. (Alternately, I think any fluffy, cool, vanilla topping would probably work to balance the heat of the cupcake, such as 1/4 cup vegan margarine + 1/4 cup vegan cream cheese + 2 teaspoons vanilla extract + 3 1/2- 4 cups powdered sugar.)
