Ever since the weekend, I’ve been thinking about purple carrot cake. Whether purple carrots would make purple cake. How to maximise the purpleness of the cake. Whether a vegan carrot cake (lacking alkaline egg-white) would get me a better purple cake than one containing eggs. Whether adding orange juice, as some recipes suggest, would counteract the egg-white, and drive the cake over the line into pinkness.
What I really want to do is set up a series of purple cake experiments, in which I test the various variables and see what colours the cakes come out. But that’s a lot of carrot cake for two people to get through, and even amusing colouring will grow old if you have four dozen carrot cupcakes to get through. So I decided instead to start by focus on making the most purple carrot cake I could. Not blue – I wanted to do some vegan (ish – these plans work better if you actually have soy yoghurt in the house) baking for a change, and besides, egg-whites can drive cake over the edge into green, and I’ve already done that. And not pink. Pink is far too easy. So purple it would be, then.
Not to put too fine a point on it, I failed. My batter wound up an alarming (but nonetheless entertaining) shade of deep blue-grey, which I thought was rather promising, but the cooked cake was just a particularly deep brown in colour. Clearly, using brown sugar was a mistake. On the other hand, the flavour was excellent. Hence this blog post – because really, these are some of the nicest carrot cakes I’ve had. And they are very nearly vegan (and dead easy to veganise, as you will see)!
Your Shopping list1/2 cup brown sugar 1/3 cup canola oil 1/3 cup sour cream or soy yoghurt 1 tsp vanilla extract 2/3 cup plain flour 1/4 tsp baking powder 3/4 tsp bicarb of soda, which should make everything more blue! pinch of salt 1/4 tsp cinnamon 1/4 tsp ginger about 2 purple carrots, peeled and grated (you should end up with about a cup of grated carrot) 1/4 cup dried cherries 1/4 cup dried blueberries 1 tbsp cacao nibs (optional) 60 g cream cheese (or soy cream cheese), softened 60 g butter or margarine, softened 1 1/2 cups icing sugar zest of one lemon blue food colouring, if you like
Now what will you do with it?
Preheat the oven to 180 °C and line a 12-cup standard muffin tin with paper cases. You may want to spray the cases with olive oil, as these cakes are sticky. I’m happy to lick cake out of paper cases, so I didn’t bother.
In a medium-sized bowl, mix together the sugar, oil, sour cream and vanilla until smooth. Sift in the flour, bicarb and baking soda, salt and spices. Don’t be afraid to mess with the quantities or types of spices.
Mix in the grated carrot, dried fruit and cacao nibs, and spoon the mixture into paper cases. Doesn’t it look dreadful? Nothing says ‘mad kitchen chemist’ like a blueish-grey cake batter.
Bake for 25 minutes or so, until done.
Let the cakes cool in their cases on a rack, and ice when cool with anything you like, really, but I like cream cheese icing, so that’s the recipe you’re getting here.
Beat together your softened cream cheese and butter (you may need to microwave them a bit to get them soft) with the lemon zest until smooth, then sift in the icing sugar and stir together well. Add some blue food colouring in order to assuage your disappointment over the boring colour of the finished cakes. Spread the icing over the cooled cakes and eat them.
Well, you can veganise this easily enough with soy yoghurt and pretendy cream cheese (it’s late at night when I’m writing this, so I can’t remember the name – yes, this is a pre-written post, I’m afraid. Hello, readers from the future!), and I should think it would work well with any gluten free flour mix you liked, or even with plain quinoa – there just isn’t all that much flour in this recipe, relatively speaking, and it’s not doing much. Almond meal might work, too. And do use whatever dried fruit or nuts appeal to you – I was just trying to maximise my odds of purpleness.
But it would be much more fun to vary this recipe to make it more colourful. I suspect that adding egg whites will only make it greyer, but one might use white sugar, to get more contrast in the batter, and you could see what happens if you added lemon juice. Or orange juice. Or blood orange juice! I may well try this myself, sometime. But if you try it first, do let me know how it turns out…
