Adapted from Nigella Lawson's recipe in How to be a Domestic Goddess
1 1/3 c flour
2/3 c sugar
3/4 tsp baking powder
1/4 tsp baking soda
1/2 tsp salt
3/4 c plus 2 tbs soft Earth Balance
3 tbs cocoa powder
1/2 c plus 2 tsp Better than Sour Cream
1/3 c hot water mixed with 1 tsp instant espresso powder and cooled
3 tsp Ener-G powder, mixed into the cooled espresso
1 tsp vanilla
Beat Earth Balance and sugar, then add wet ingredients. Add the dry all at once, and stir until just combined. Liberally spray/butter a loaf pan or higher-edged 9" cake pan (I used the loaf with good results). Bake in a pre-heated 350 oven for about 20-25 minutes, until a tester comes out clean. Leave the cake in the pan for about ten minutes, then flip out to cool. My cake sunk a bit, and wasn't very stable, so be careful with this step (or prepared to fix it with the frosting!).
3 oz. dark chocolate bar (semi-sweet is best)
3 tbs Earth Balance
1/4 c Better than Sour Cream
1/2 tsp vanilla
1/2 tbs light corn syrup
2 c confectioners' sugar, sifted
Melt the chocolate and Earth Balance in the microwave (careful to stir it frequently and not let the chocolate burn). Let cool a bit, then stir in the sour cream, vanilla, and syrup. Add the confectioners' sugar, blending until smooth. You want it thick enough to spread, so add hot water to thin it or more sugar to thicken. Frost the cake.
This fed about six of us for dessert, and we served it with fresh strawberries.
