  • your favourite sugar biscuit recipe and its ingredients
  • cookie cutter set
  • rolling pin
  • parchment paper
  • thick dowels, 2 each
  • white fondant
  • can of white icing
  • offset spatula
  • unused paint palette
  • assorted pastry brushes (recommended) OR unused craft paint brushes
  • clear vanilla extract
  • gel food colouring in your choice of shades
  • toothpicks
  • paper towels


Step 1: Create your sugar biscuit dough according to the recipe instructions, omitting baking powder if it is included in the recipe. Baking powder causes the cookies to spread during baking, and omitting it will help the cookies retain their original shapes.

Step 2: Roll out your dough using the dowel method: on a clean surface covered with parchment paper, place a ball of dough and two 1/4″ dowels on ether side of it. These dowels will serve as the “guides” for the rolling pin to ensure the cookies are about ½ cm thick throughout. Place your rolling pin on top of the two dowels, and roll the dough out as normal. Cool your dough on a cookie sheet in the fridge for 10–15 minutes, then cut the shapes out of the dough. Let the shapes cool in the fridge for another 10–15 minutes (or as directed by the recipe), then bake according to the recipe instructions. Set the cookies aside to cool, then store in an airtight container until ready to use.

Step 3: Roll out the fondant to 1 mm thick using the dowel method. If you’re using a fondant roller (recommended for a truly flat surface to the fondant), dowels will likely not be necessary. Most fondant rollers come with plastic ring guides that have set thicknesses. Remove all of the rings except the ½ cm rings from either side of the rolling pin, and roll out the fondant as usual. If you are using the same rolling pin you used to roll out the dough, clean and dry it first to ensure no grease or moisture transfers to the fondant.

Step 4: Cut the fondant using the same cookie cutter you used to cut the cookies. Like the rolling pin, it should be cleaned and dried before use to prevent grease and moisture from transferring over. Set aside the fondant on baking paper and allow it to air dry for an hour or two so that the top firms up a bit. It can be left out overnight, as well.

Step 5: Turn the dried fondant shapes upside down and spread a thin layer of white icing over the back with an offset spatula. Gently flip the fondant shape over and centre it on top of a sugar cookie. Cover the cookie with a small bit of baking paper and, with the palm in your hand, rub in small, gentle circles to “glue” the shape onto the cookie. Set the finished cookies aside and allow icing to air dry to “set” the fondant shape in place.

Step 6:  While the fondant is setting, mix your food colouring watercolours. Because gel food colouring is very concentrated, you need very little for this project. Dip a toothpick into the gel food colouring to control how much is coming out, and dilute the food colouring with clear vanilla extract. (Note: Do not use water. The alcohol content in extract helps it evaporate faster in the air so your fondant and cookie won’t get soggy. It also adds some yummy extra flavour!) Test the colours by dipping the paintbrush and painting on a white paper towel.

Step 7:  Paint the cookies as desired! Experiment with mixing colours, layering colours, and even removing colour after it has been applied with a clean paper towel! Allow to dry for up to 30 minutes after being painted, and enjoy!
