Cupcakes are ideal for kids because they're small and easy to run around with (which inevitably happens). We see so many pretty cupcake liners on food blogs, but only seem to find the (blah) foil and pastel liners at our grocery store. Perhaps you have better local options, but if not we have three online sources to recommend...
• Layer Cake Shop has a ton of liners to choose from as well as cupcake decorating kits and pretty much everything you could want to decorate and package up treats from your oven.
• Don't be put off because Cute Cups is based in Singapore. This Etsy shop has liners you won't find anywhere else as well as muffin cups and lots of different sized cups for holding candy. (Shipping is very reasonable too).
• Even if you're an infrequent baker, you may get lost for awhile at Bake It Pretty looking at all the liners, cookie cutters, candy molds and much more.
If you have another great online source for cupcake liners, please add it in the comments!
