Instructions
Cut and Bake the Cookies
Roll the cookie dough out to ¼-inch thickness.
Cut the rolled dough with a sombrero cookie cutter.
Bake the cookies on parchment lined cookie sheets according to your recipe's instructions.
Allow the cookies to cool to room temperature before starting the royal icing.
Outline the Cookies
Using yellow icing in a disposable piping bag fitted with a small round tip, such as a #2, outline the cookies. Allow the icing to dry for at least 1 hour before flooding.
Cap or seal off the tip of the yellow outline-consistency frosting, and set it aside for later.
Flood the Cookies
Thin yellow icing with small amounts of warm water to flood consistency icing. Transfer the icing to a disposable piping bag fitted with a large round tip or the tip cut off of the bag.
Flood the icing inside the outline. Use a toothpick or a scribe tool to guide the icing to the edges and to swirl the wet icing to remove any bubbles.
Allow the icing to dry until set, up to 24 hours. How quickly it dries will depend on the temperature and humidity of your workspace.
Add the Details
Fill disposable piping bags fitted with small round tips with outline consistency icing in the colors of orange, blue, pink, and green. Squeeze a small amount of the outline consistency yellow icing out on a paper towel to ensure it is flowing the tip properly.
Pipe outline consistency red icing around the brim of the hat as show in the photo.
Pipe an upside-down "U" shape of yellow outline consistency icing to represent the part of the hat that fits on a head.
Pipe a line of red outline consistency icing across the top of the hat, then pipe a line of blue outline consistency icing underneath the red.
Pipe alternating orange, blue, pink, and green dots underneath the red line representing the brim of the hat.
Pipe a squiggle of orange icing at the top of the hat, then pipe blue dots above the squiggle and pink dot below.
Allow the icing to dry completely before storing or packaging in treat bags.
Notes
Cut Out Sugar CookiesShortbread CookiesEasy Royal IcingStorage:Once the icing has dried completely, store them in an airtight container at room temperature in a single layer. I do not recommend stacking the cookies unless you place aluminum foil between the layers to prevent grease transfer from the top cookie to the bottom cookie.You're Gonna Bake It After Allbakeitafterall.com
