But what is a cookie stamp exactly? Well, cookie stamps are embossers, and they create a raised 3D effect in fondant.
The stamps are suitable for professional and home bakers alike, and you can also get suitable cutters to crisply frame your cookies, just like this.
They're used to take the look of your baked goods to the next level, and are perfect for just about any event.
The best part? You don't need to be a skilled baker or decorator to use the stamps. You simply sprinkle corn flour on your surface, then you'll be ready to roll out your fondant with a rolling pin.
Then place the stamp on the fondant, and press down over the stamp, and once you remove the stamp, you'll be left with a raised design.
You can also frame your cookie with a suitable cutter, so that your cookies are shaped just how you want them.
Home cooks everywhere are just about obsessed with the cookie stamps and cutter, which you can buy here, and can't get over how creative the designs can be.
