Sweet Caroline (saberina) shows you how to make these vintage quilted cookies in her step-by-step tutorial. This shabby-chic cookie is perfect for a baby shower, easter, bridal shower, or high tea!
Once you have baked your cookies, let them cool completely. With the help of a ruler, paint the grid with an edible pen.
Follow your recipe to make Royal Icing. All the royal icing I used, has flooding consistency. You will need white, 2 shades of green– I used a mix of avocado (Americolor) and Moss (Wilton)– and 2 shades of pink– I used rose (Wilton). All the color are piped with tip 1.
Begin filling the white squares that do not touch each other. Since you will have to work fast to make the flowers on wet icing, feel free to fill in the number of squares you feel comfortable with. I work with four at the same time.
To make the flower effect, ice a big drop of light pink icing and one smaller of dark pink over it. With a toothpick or a scribe tool to swirl the icing until they look like a rose. Make the leaves icing one drop of light green and one little dot of dark dragging with the toothpick.
Continue filling the white squares that do not touch each other, and repeat the process of the flower over the wet icing. At this point, you will have to wait between 20 and 30 minutes to repeat the process with the next batch of white squares and flowers.
Repeat again the last step until you finish all the white squares. Remember to wait 20 minutes between the batches.
After 20 minutes, begin filling the light pink squares that do not touch each other.
Wait 20 more minutes and finish the last pink squares.
