I only need a little bit of icing to write on a cake and I don't want to make a whole batch of buttercream. What can I use/do instead?
Colored piping gel?
You could make a smaller batch or a glaze with powdered sugar and water, use chocolate/candy melts, or piping gel (like TexasSugar suggested).
Wilton has small tubes of icing perfect for just writing or small details.
I'd cheat and buy it!
I prefer writing with chocolate so, I use colored compound choc. as well as my baking choc.. Just warm/melt as much as you need. I actually think it's easier to write a fine line with.
i always stock up on chocolate and white canned frosting when our local store offers it for 50-75 cents a can. can always tint the white, and the chocolate is always good to have on hand. Just that last minute to write with or put on a cupcake or something ... (or for that sweet tooth)..lol.
it has saved me so many times just having it on hand.
I normally just mix a little PS, Crisco and water together until I get the consistancy I am looking for
Thanks everyone! I ended up just using PS and water. Was a little tricky but I got it eventually.
