Icing and frosting can be naturally colored blue with homemade blue food coloring! This beautiful baby blue frosting is dyed with a vegetable! 😀
I used the natural blue frosting and icing for mini cakes. I think that they look like little blue clouds! 😀
Natural Blue Frosting:
- natural blue custard
- 200g butter
- 50g powdered sugar
Natural Blue Icing:
- powdered sugar
- boiling water
- some drops of homemade natural blue food coloring
For the natural blue frosting, make the custard and let it cool completely. Using an electric mixer, beat butter and powdered sugar until creamy. Add custard, 1 – 2 tbsp at a time, beating after each addition.
Because red cabbage dye is ph-sensitive, butter changes the color of the frosting: While natural blue custard is rather teal, the frosting is baby blue!
For the natural blue icing, stir together powdered sugar and boiling water. Color icing with some drops natural blue food coloring. Here I used the natural blue icing to make speckled blue robin egg truffles.
