Because I didn’t get blue cake, when I made my naturally colored rainbow cake, I tried to make blue cake again. I followed this recipe for rainbow cake with homemade natural food dyes. It’s a different recipe than the one I used last time: It’s made with egg whites and yogurt. The blue cake layer is naturally colored with blueberry juice.
I made three muffins: One is colored with blueberry juice according to the recipe, another is colored with red cabbage juice (without baking soda) and the third is colored with my homemade natural blue food coloring (made with red cabbage and baking soda) + extra baking soda.
Here are the results: The blueberry muffin didn’t turn blue, it’s just purple! 🙁 It’s also very dense. But the red cabbage & baking soda muffin turned a beautiful turquoise! Yay! 😀 The muffin was also very delicious – it didn’t taste of red cabbage at all. I think I’ll experiment a bit more with red cabbage colored cake, when I find the time.
I also made natual blue polka dot cake! 😀 After baking, I just colored the cake with drops of natural blue food coloring. It’s such a dark blue, isn’t it?
Here you’ll find part 2 of my natural blue cake experiment.
