Tender, chocolatey Vegan Chocolate Cupcakes frosted with a sumptuous vegan chocolate buttercream are out-of-this-world good! This one-bowl recipe is easily adapted to being gluten-free.
Preheat oven to 350℉. Line a 12-cup cupcake tin with cupcake liners.
Whisk together the flours, sugar, cocoa, baking soda and salt. Add the oil, vanilla, vinegar and water. Whisk and mix together until smooth.
Pour into prepared pan and bake for about 20-25 minutes, until a tester inserted in the middle of a cupcake comes out clean.
Remove from oven and cool in pan for 5 minutes, then turn out onto a rack to cool completely.
For the Frosting
Heat chocolate a double boiler until melted. Let cool to room temperature.
In a bowl, of an electric mixer fitted with the flat beater, combine the powdered sugar, margarine, nondairy milk, and vanilla and beat on low speed until combined, about 1 minute. Stop the mixer and scrape down the sides of the bowl. Increase the speed to medium and beat for 2 minutes, then reduce the speed to low.
Add the chocolate and beat until combined, then increase the speed to medium and beat for 1 minute more.
