Simple Citrus Slice Cookies

These zesty sugar cookies can easily decorated with royal icing. They’re fun and easy to make!

List of Materials

  • NFSC – No Fail Sugar Cookie Recipe (add citrus juice & zest of your choice)
  • Royal Icing (Antonia 74′s Recipe)
  • Round Cookie Cutters (size your choice)
  • Piping Bags
  • Couplers
  • Piping Tips (#3)
  • Yellow, Orange & Green Gel Coloring (colors your choice)
  • Toothpick


- Outlining – Using a #3 piping tip, outline your cookie with royal icing. I like using a larger piping tip to outline and fill in larger areas, as the ‘flooding’ goes faster.


– Flooding – Fill in the center of your cookie with the same piping bag and icing, either right away to help the icing melt into each other, or 10 minutes later if you’d like to see a distinct outline. I use the same icing to outline and fill in, as it saves time.


- Shaking – Shake gently to help smooth icing over. A couple of tips – You need to be gentle with the cookie while you’re shaking it, so that it doesn’t break, and working quickly is important so that the base doesn’t start to dry.


– Wet on Wet Technique; The 2nd Layer – Using a #6 piping tip and white icing, pipe a circle close to the perimeter of your cookie and a dot in the center. (You can use a smaller piping tip here, it’s personal preference. I liked the look of a thicker white line).


- Marbling – Drag a toothpick through the wet icing, starting from the outside and working your way to the center of the cookie. If you’re particular about every line being perfectly white, with no little dabs of color, wipe your toothpick between each drag. Working quickly is important as the royal icing starts to set almost immediately.


- Shaking – Shake gently to help smooth icing over.


– Drying – Let your icing dry for 12-24 hours, depending on the humidity in your area. Package in cellophane bags or serve and enjoy!

Thank you for sharing this! My kids and I have been wondering what we can make for the other kids in our neighborhood. I believe these cookies are just the thing. Thanks, again!


Thanks so much!

What I love about these is that they're really quite simple to make, and the marbling is fun (my kind of fun, haha).

@mo63 The cookies don't seem to go stale for the time period that the icing dries. The icing acts as a sort of sealant.


These came right on time!!!! I'm doing cookies for a Summer get together and was thinking of doing lemon cookies for it.... Thanks again for the tutorial!


The following is the recipe I use to ice cookies. It hardens nicely and leaves a slightly shiny sheen. It is opaque, it's not a glaze.

• 1 cup confectioners' sugar • 2 teaspoons milk • 2 teaspoons light corn syrup • 1/4 teaspoon almond extract • assorted food coloring Directions 1. In a small bowl, stir together confectioners' sugar and milk until smooth. Beat in corn syrup and almond extract until icing is smooth and glossy. If icing is too thick, add more corn syrup. 2. Divide into separate bowls, and add food colorings to each to desired intensity. Dip cookies, or paint them with a brush. 3. Add water ½ tsp. at a time until consistency you need


The truth is, I decided to go for it and try it. My daughter was excited to cash in her coupon for Mommy time and she wanted to make sugar cookies. It didn't take much convincing for her to agree to these. I'll let you know how it works.



They were ok; probably the royal icing would be better. I also have to experiment with how thin the icing would be. I might have to try them again in the future.


That's great @cookiekisses. You can find Antonia74's royal icing recipe here on cake central and I've shared it on my site in the recipe section. If you like, I also have a video on finding icing consistency. Have fun decorating!
