De Buyer Silicone Macaron Templates
If you feel like splurging you can buy these French macaron silicone mats for easier piping. I bought these at E. Dehillerin in Paris. These mats are available at some international specialty cookware stores online, but if you aren’t making macarons very often the templates below work just as well, especially since you will be laying parchment paper over the templates anyway.
Print this template as is for mini macarons, or scale up when printing for larger macarons. Print two copies per half sheet pan (13″ x 18″). Happy piping!

Thank you for this! I’ve been having trouble keeping my macarons circular… I kept getting ovals. But I suppose it can’t be helped with just using store-bought zip-lock bags with a hole cut out in one of the corners, instead of true piping bags with a real, metallic tip.
Try mixing the batter with 1 or 2 less strokes. This will make the batter thicker, where they might have pointy tips after you pipe them, but then you can fix that with 1 or 2 more counter slams. And of course, a tip will certainly help too. 🙂 I feel like I need to make some macarons now!! 😉
