Vegan cupcake with Cashew frosting

I found a post about the vegan frosting made from cashews on a food blog, Roost and it sounded very interesting! What a clever idea.
I gave it a try and it turned out very good. It's a good alternative to buttercreme.
I followed the recipe below, but replaced coconut oil with Tahini.

The cashew cream (The recipe from Roost)

2 cups raw cashews, soaked for 3 hours, drained and rinsed
juice from 3 lemons
4 dates, pits removed
1 TBS coconut oil (this does not need to be warmed just scoop it right out of the jar)
1 tsp vanilla extract
1/4 tsp salt
orange juice

Place all ingredients in a high speed blender (a rinky dink blender will not do the trick!) and blend until you have a very smooth consistency. Add more OJ if you need to thin it out.

Since the frosting is vegan, I wanted to make some kind of vegan cupcakes.
I was browsing around for it and found this interesting cupcake recipe on a Japanese website!
This recipe requires no egg, no milk(even soy milk)........ but the chemical reaction of baking soda and vinegar to increase the volume!!
I've used this reaction for cleaning......
When those two are combined, it starts bubbling up and breaks down stains.
Well you might say "Seriously? Vinegar for cupcakes?".
But trust me! It doesn't taste vinegar at all.
I changed some ingredients of the original recipe to make it healthier.

Vegan cupcakes

100g Whole what flour
3TBS Cocoa powder
3TBS Brown sugar
1.5tsp Baking Powder
1/2tsp Baking Soda
2TBS Oil
110cc Water

Preheat oven to 350F.
Combine dry ingredients.
Add wet ingredients except vinegar and mix well.
Add vinegar and mix quickly.

*Don't try to make many at a time.. You might not be able to get the volume you want.
The softest cupcake I've ever had! Enjoy:)
