Instructions
Sugar Cookies
Beat together your sugar and butter until combined. You can use your stand-mixer or a hand-mixer.
Add your eggs and combine. Add remaining ingredients and stir for 1-2 minutes for the dough to really come together. It should stick to the paddle of your mixer attachment when it’s ready and not be sticking to the bowl. *If it is sticking to the bowl you might need to add a bit more flour. It should come off easily with a wooden spoon.
Divide into two parts and roll out your dough. I use two cookie sheets for this amount. Stack them with parchment paper in between the layers. Put in the fridge for a minimum of 30 minutes. Allowing the dough to chill will help it set up and hold the shape of your cutouts.
Once the dough has chilled, cut out your shapes and preheat your oven to 350 degrees. Take the first cookie sheet full of shapes and place in the freezer for 7-10 minutes. This minimizes spread.
Bake for 9-12 minutes. This is a variable that’s really determined by your oven temp and cookie softness preference. Play with it a bit to see what works best for you. Allow the cookies to cool on the cookie sheet, the cookies will finish baking directly on the sheet.
Royal Icing
Combine powdered sugar and meringue powder in bowl or stand-mixer. Allow to stir for 1-2 minutes to combine.
Add your water. Run stand mixer for 2-3 minutes to combine.
Separate into bowls as many colors as you're planning to use, and add your gel food coloring. Mix colors and bag. Clip the end of the bags to begin decorating.
Race Car Design
Start by outlining the body of the car, leaving room for the wheels to be filled in.
Next, fill or flood your cookie with the color of your car. For the cars I used a few shades of blue, red and yellow since they were our main party colors.
Using your white royal icing, fill in a dot in the middle of the race car cookie. You'll let this dry completely and add the car details.
Once the icing has dried completely, add tires with black royal icing. Add a steering wheel by making a line towards the hood of the car.
Finally, write or pipe on (whichever you're more comfortable with!) the number 3 on the size of the car.
