bright blue batter darkens down when baked |
I recently volunteered to make cupcakes for a baby shower. Our co-worker is expecting a boy so the general consensus was for blue icing.
Being me, I decided to take the opportunity to experiment and tweaked my red velvet cake recipe to make blue cupcakes instead.
There's a misconception that red velvet cake is simply a white cake with red food colouring.
The main ingredients in a red velvet cake are dutch processed cocoa powder, vinegar and buttermilk.
cocoa powder natural vs. dutch processed |
The alkali renders the powder neutral so, unlike natural cocoa powder, dutch processed powder will not activate the leavening agent (the thing that makes the cake rise) in the baking soda which is where the vinegar comes into play.
The very last step in any velvet cake is mixing the baking soda with vinegar and then folding this foaming mixture into the batter. It is important to use fresh baking soda (no more than 30 days old) in this step or you run the risk of falling cake syndrome.
And finally, buttermilk is what gives velvet cake its legendary moist and fine crumb.
making 2 types of cupcakes? extra batter? make an extra cake! |
I am happy to report: the cupcakes were a smashing success!
What's your go-to for deliciously moist cupcakes?
Yields: A 3 tier 8 inch cake or 24 cupcakes
