For the lemon cake I tried a flour buttercream from The Tough Cookie. It was good although it tasted rather like vanilla pudding and got soft easily.
Vegan Chocolate Buttercream (not pictured)
Mix 1/2 c water, 1/2 t salt, and 2 T cornstarch. Cook stirring constantly until cornstarch thickens. Mix in 1 c sugar and stir until dissolved. Keep cooking to thicken further, watching closely and stirring while reducing heat if necessary.
Cool to room temperature.
With a mixer, beat in 3 T shortening (helps to stabilize it) and 3 T coconut oil (helps it set in the cold). Add 1/4 c cocoa powder, 1 t cinnamon, 1/8 t cayenne, 2 t vanilla. Chill in refrigerator for 10 minutes. Beat again (chilling should help it stiffen properly if the room is warm) and gradually beat in 1 c of vegan margarine and 3 oz of melted dark chocolate. Continue beating, alternated with chilling time, until fluffy and creamy. Store in the fridge but warm to soften before use. Note that it must be kept cooler than room temp or it will melt and possibly sag and lose the fluffy texture. The cake should be refrigerated after frosting. (and in between layers if needed)
Next time:
Try more cornstarch. Possibly more sugar. Maybe more cocoa. And vary the other flavors as desired.

The cake is fully frosted. I just have to remove the parchment shields from the tray. |
