this is the recipe i used, from the blog bake bake bake - but maybe don't read this until the end because the picture may give you unrealistic expectations! as the number one thing i learnt (or reaffirmed) during this bake is that english food colouring just is not the same as american, as you will see.
as with a normal red velvet cake, this recipe required buttermilk so remember the trick to make your own - one cup of milk mixed with one teaspoon lemon juice, left to stand for 10-15 minutes will be a fine substitute.
being by creaming the butter and sugar - then add your eggs one at a time
then in a separate bowl you want to make the blue suede part by mixing together the food colouring and coco powder. if you're using a liquid food colouring this will seem a bit strange at first because the two ingredients really separate - you'll have a layer of coco powder with the food colouring underneath. there will be a sciencey explanation for this i'm sure, but if you mix it hard enough (use a creaming action) they will eventually come together
you can just about see the blue coming through in the right hand photo
reading back over the recipe now, i feel like i might have freestyled from this point onwards - but it came out fine so no fear! you want to alternate adding the milk and dry ingredients (flour, baking powder) to the sugar mix so it never goes too dry or wet.
you want a nice fluffy mixture - mine went super glossy which made it hard to resist
then came the fun part of adding the food colouring mix in. as you can see, this went rather more green than blue - i kept adding more food colouring in but i don't feel it made that much difference and it does begin to add a weird taste so try to resist doing this!
my super glossy, but rather green mixture
then it is in to the oven for baking, when it comes out it's hard to tell what the final colour is. you can get a hint through the cracks but the big reveal is saved for later.
while the cake is cooling you want to make your cream cheese frosting. personally i find cakes completely smothered in this too sickly, so i decreased the quantity and 'just' iced the middle and top (i say just, this was still three thick layers)
ice your bottom layer, then add a covering of blueberries. then ice over these - i decided this was easier than icing and flipping over the other cake layer, that just seemed like a recipe for disaster.
then place the next cake layer on, ice and decorate with any leftover blueberries.
this cake did turn out to be a bit of a monster!
now if you aren't put off by the sheer size of this cake, you will be rewarded by cutting in to it and getting the colours and layers.
i think it's really cool to get the blueberries running through the centre, and they add a much needed zing against the sweetness of the cream cheese frosting.
have you made any unnaturally coloured bakes recently? perhaps it's time to crack out the food colouring to add a little pizzaz to your normal bakes!
next time it's back to brownies (not again i hear you groan but, trust me, these are worth it). until then bakers!
love,
