Small bowls (for coloring)

Importance of Each Tool

Mixing bowl: A good-sized bowl allows you to mix ingredients thoroughly without spills.
Whisk or spoon: Essential for achieving a smooth consistency in your icing.
Measuring cups and spoons: Ensures precise measurements for consistent results every time.

Ingredients

Ingredients:
– 2 cup powdered sugar
– 1 & 1/2 tbsp corn syrup
– 1/2 tsp vanilla extract
– 1 & 1/2 tbsp milk or water (cold)
– gel food coloring

Step 1: Prepare the Mixture

Sift the powdered sugar in a medium/large bowl to remove any lumps.
Add in the corn syrup, vanilla extract, and milk or water.
Stir vigorously until the mixture is smooth and has no clumps.

Step 2: Adjust Consistency

Check the consistency of your icing. If it’s too thick, add a little more milk or water, one teaspoon at a time.
The ideal icing should slowly fall off the spoon while leaving a thick layer behind.

If you want multiple colors, divide the icing into smaller bowls.
Add gel food coloring to each bowl until you achieve your desired shades.

Step 4: Decorate Your Cookies

Use the colored icings to decorate your sugar cookies creatively.
Allow the decorated cookies to set at room temperature before storing them in an airtight container.

With this easy-to-follow recipe for Sugar Cookie Icing That Hardens, you’ll be ready to impress friends and family with beautifully decorated cookies all year long!

When it comes to serving sugar cookies decorated with icing that hardens, presentation is key. Here are some creative ways to showcase your beautifully iced treats.

Arrange a selection of iced sugar cookies on a large platter. Use different shapes and colors to create a visually appealing display.

Gift Boxes

Place individual cookies or small stacks in decorative boxes. This makes for a delightful homemade gift during the holiday season.

Fill clear jars with your decorated cookies. This not only looks attractive but also keeps the cookies fresh longer.

Dessert Table Centerpiece

Include your iced sugar cookies as part of a larger dessert table spread. Pair them with other sweets for a festive look.

Party Favors

Wrap cookies in cellophane bags tied with ribbons. These make excellent party favors for guests to take home.

To achieve the best results with your sugar cookie icing, consider these helpful tips.

Sift the powdered sugar: Sifting helps remove lumps and ensures a smooth icing consistency.
Adjust liquid carefully: Add milk or water slowly until you reach your desired thickness; too much can make the icing runny.
Use gel food coloring: Gel colors provide vibrant hues without altering the icing’s consistency significantly.
Let it dry completely: Allow your decorated cookies to set at room temperature for several hours for the best hardening effect.
Store properly: Keep completed cookies in an airtight container to maintain freshness and prevent moisture from affecting the icing.

While sugar cookies are delightful on their own, pairing them with side dishes can enhance your dessert experience. Here are some tasty options to consider.

Hot Cocoa: A warm cup of hot cocoa complements sweet cookies perfectly, especially during chilly days.
Fruit Salad: A fresh fruit salad offers a refreshing contrast to the sweetness of the cookies.
Cheese Platter: Include various cheeses; their savory flavors balance out the sweetness of the icing.
Milk Shooters: Small glasses of cold milk are classic companions that pair beautifully with sugary treats.
Coffee Bar: Set up a coffee station where guests can enjoy their favorite brews alongside iced sugar cookies.
Ice Cream Sundae Station: Let everyone create their own sundae, making it a fun and interactive dessert experience.
Nut Mix: A savory nut mix adds crunch and flavor, creating an interesting combination with sweet and soft sugar cookies.
Chocolate Fondue: Provide fruit and marshmallows for dipping alongside your iced sugar cookies for an indulgent treat.

Common Mistakes to Avoid

When making sugar cookie icing that hardens, it’s easy to make a few common mistakes. Here are some tips to help you achieve the perfect icing.

Incorrect Consistency: If your icing is too runny or too thick, it won’t set properly. Adjust with more powdered sugar or milk until you reach a thick but pourable texture.
Skipping Sifting: Failing to sift powdered sugar can lead to lumps in your icing. Always sift before mixing to ensure smoothness.
Not Letting It Set: If you don’t allow the icing to dry properly, it may smudge when stored. Be patient and let it set at room temperature for optimal results.
Using Non-Quality Ingredients: Cheap ingredients can affect the flavor and texture of your icing. Use good quality powdered sugar and pure vanilla extract for the best taste.
Neglecting Color Mixing: Adding food coloring all at once can lead to uneven colors. Gradually add gel food coloring and mix until you achieve the desired shade.
Rushing Storage: Storing cookies too soon after decorating can ruin your hard work. Ensure the icing is fully set before placing cookies in an airtight container.

Storage & Reheating Instructions

Refrigerator Storage

Store leftover sugar cookie icing in an airtight container.
It will last up to one week in the refrigerator.

You can freeze the icing for up to three months.
Use a freezer-safe container or bag, removing as much air as possible.

Oven: Preheat to a low temperature and place the container inside until soft.
Microwave: Heat in short bursts (5-10 seconds) until just warm, stirring between intervals.
Stovetop: Use a double boiler method, gently heating while stirring until smooth.
