These cupcakes were for my sister-in-law’s birthday.
The red and black colouring nearly killed me. I used a couple of bottles of gel colour, as well as at least one or two bottles of liquid colouring, for both the cakes and icing. I based the black cakes on chocolate Betty Crocker cake mix and tub of icing, and the red ones on vanilla Betty Crocker cake mix and tub of icing.
Even using the gel, I never got a true black in either the cakes or icing.
Topped with red candy hearts and black edible glitter.
End result wasn’t too disastrous, though.
