These gorgeous Valentine’s Day cookies are sure to impress anyone this Valentine’s Day. Whether you are making these cookies for a teacher, friend, coworker, or your hubby, I am sure they will love these cookies! I love the marbled effect on sugar cookies! The design is so elegant yet so simple to make!

How to Bake Sugar Cookies

‍

Preheat oven to 350°F 

‍

Combine ¾ cup shortening  and 1 cup sugar together and then add in 2 eggs and ½ tsp vanilla. In a separate bowl, mix 2 ½ cups flour, ¾ tsp baking powder and 1 tsp salt together. Add the dry ingredients to the wet and mix until a smooth dough ball is formed. Roll out the dough about a ¼ inch thick onto a baking sheet with either parchment paper or a silicone baking mat. Bake cookies for 10 minutes at 350°F. Let them fully cool before dipping in royal icing. 

‍

Pro Tip: Make sure the dough is rolled out somewhat thick so that the cookies are easy to grasp when dipping in royal icing. 


Using Heart Cookie Cutters 

‍

I have a few different heart shaped cookie cutters I have collected over the years. I like to use cookies that are in the 3” to 4” size for dipping. Heart-shaped cookies are one of the easiest shapes to dip. The smooth curves help the icing drip off nicely, so you get clean edges without much effort. They’re easy to hold and easy to dunk.

How to Make Royal Icing (Base)

‍

Mix 4 cups of sifted powdered sugar, 3 Tbs meringue powder and gradually add in 5 Tbs room temperature water. Next add in1 Tbs of white gel food coloring and 2 Tbs corn syrup. The consistency of the royal icing should be thick like toothpaste. This is the base icing so that you can add color to it, and thin it out as needed. 

‍

Pro Tip: It helps to prepare the royal icing a day in advance to allow air bubbles to come to the surface.

‍

Create Colors for Marbling

‍

You can make marbled cookies with any colors, but for Valentine’s Day, I am using two colors: white and pink. I use a pasta bowl for dipping the sugar cookies into the royal icing. 

First, add 3 tablespoons of the base icing to a small dish and thin it by gradually mixing in 1 tablespoon of room-temperature water. Next, take a small amount of the base royal icing and tint it lightly with pink gel food coloring. Spoon or pipe the pink icing in thin stripes over the base icing.Reserve a little of the pink icing and add more pink gel coloring to create a darker shade. Add a few more thin stripes of the darker pink over the lighter pink and base icing. If you like, you can take a toothpick or a cookie scribe tool to gently swirl the icing to create a marbled effect without overmixing. This is not necessary because dipping in the cookies in the icing will naturally create a marbled look once the cookie is lifted from the icing.

‍

Pro Tip: Be careful not to thin the icing too much. It should be thick enough that it doesn’t run right off the cookie, but still thin enough for a little excess to drip off smoothly.

‍

Dipping the Cookies 

‍

Hold the cookie by the edges and gently place it flat into the icing. Slightly move the cookie around to make sure all sides are fully coated. Lift the cookie and let the excess icing drip off, then place it icing-side up. Gently shake to smooth the icing, or use a cookie scribe tool to fill in any bare spots.

‍

Pro Tip: Use a shallow dish for dipping your cookies. That way you aren’t wasting excess icing, and it is easy to dip the cookies in and out.

‍

Letting the Cookies Dry

‍

Allow your cookies to dry completely—this usually takes about 8 hours. If you're in a hurry, you can speed things up by popping them in a dehydrator at 95°F for 20 minutes. This creates a "crust" on the surface, which is perfect if you want to pipe lettering over your marbled design.

With the use of the dehydrator, they might finish drying in about 4 to 6 hours, but keep an eye on the humidity. I’ve found that cookies dry beautifully in the winter (January and February), but summer humidity can be tricky. During those humid months, I like to run a fan over the cookies before they go into the dehydrator to prevent any rippling.

‍

Storing Cookies 

‍

Once your cookies are fully dry, they’re ready for the finishing touch! Place them in clear cellophane bags and secure them with a ribbon or twist tie. For the best taste and a soft texture, they should be enjoyed within 2 to 4 days.

If you're planning ahead, these cookies freeze really well. Simply place them in a freezer-safe Ziploc bag, gently press out the air, and lay them flat in the freezer. They can be stored this way for up to 6 months. When you're ready to serve, take the bag out and let it sit on the counter until the cookies reach room temperature before opening as this prevents any condensation from ruining the icing.

How to Make Beautiful Marbled Valentine's Day Cookies

Makes
24-36 cookies

Ingredients

Dough

¾ cup shortening

1 cup sugar

2 eggs

½ tsp vanilla

2 ½ cups flour

¾ tsp baking powder

1 tsp salt

Royal Icing

4 cups powdered sugar, sifted

3 Tablespoons meringue powder

9 Tablespoons room temperature water

2 Tablespoons corn syrup

1 TBS of white gel food coloring

Instructions

Dough

Preheat oven to 350°F. Line a baking sheet with parchment paper or a reusable silicone mat.

In a large bowl, beat the ¾ cup shortening and 1 cup sugar together until smooth and lighter in color (about 1–2 minutes by hand, 30–60 seconds with a hand mixer).

Add the 2 eggs, one at a time, beating briefly after each until incorporated. Stir in the ½ tsp vanilla.

In a separate bowl whisk together 2½ cups flour, ¾ (or ½–¾) tsp baking powder, and 1 tsp salt so the baking powder and salt are evenly distributed.

Gradually add the dry mixture to the wet ingredients, mixing just until a soft dough forms. Don’t over mix. Stop when there are no large streaks of flour.

Roll out the cookie dough onto the prepared baking sheet, and use any cookie cutter of your choosing and remove the excess dough. Space cookies about 2 inches apart.

Bake in the preheated 350°F oven for 10 minutes. Start checking at 7–10 minutess to prevent cookies from getting brown edges. Cookies will be done if you no longer see a "translucent" center.

Remove from oven and let cookies sit on the baking sheet for 2–3 minutes, then transfer to a wire rack to cool completely.

Once cooled, store cookies in an airtight container at room temperature for up to 4–5 days, or store in freezer for up to 6 months.

Royal Icing

Mix sifted powdered sugar and meringue powder in a medium bowl.

Add in corn syrup.

Add in water gradually, one tablespoon at a time.

Add in white gel coloring as a base before adding in other colors.
