Fancy a fluffy cupcake?

If you'd prefer your cupcakes or cakes fluffy, airy and light as compared to moist, dense and heavy... This is it. 

The part of this recipe that makes me happy? 

Only 5 tablespoons of unsalted butter, and no yolks at all! 

I'd reckon pairing this delicate baby with a summery frosting. Thinking of strawberry or mango buttercream frosting. Something that isn't too sweet.
