Conversation Heart Cookies

Valentine’s Day always stirs up mixed feelings for me. On one hand, there’s the whole over-the-top pressure of roses, expensive dinners, and shiny gift boxes.

On the other hand, I love the idea of making someone feel special in a simple, thoughtful way.

And let’s be real—anything heart-shaped is automatically adorable. That’s where these conversation heart cookies come in!

Buttery, melt-in-your-mouth, and totally customizable, these cookies are the perfect way to share a sweet (or funny!) message with someone you care about.

Instead of grabbing a generic box of chocolates, why not create something personal? You can write heartfelt notes, inside jokes, or even silly puns right on the cookies.

They’re as fun to make as they are to eat, and they’ll definitely bring a smile to anyone’s face. Here’s how you can make these cookies the star of your Valentine’s celebration with a simple, step-by-step recipe!

Conversation Heart Cookies Recipe

Ingredients

For The Shortbread

2 cups all-purpose flour
1 cup (2 sticks) softened unsalted butter
1 cup powdered sugar
1 teaspoon salt

For The Icing

4 egg whites (pasteurized recommended)
3 pounds powdered sugar, sifted
2 teaspoons lemon juice
Food coloring
Piping bag
Small round piping tip (size No. 2)

Instructions

Making The Shortbread Cookies

In a mixing bowl, use a hand or stand mixer with a paddle attachment to beat the butter on high speed for 1–2 minutes until smooth and fluffy.

Lower the speed and slowly add powdered sugar, allowing it to mix thoroughly. Increase the speed again and beat until the mixture is creamy.
Add salt, then gradually mix in the flour on low speed. The dough will be crumbly at first but should hold together when pressed.
Shape the dough into a ball, then roll it out evenly to about 1/4 inch thickness. For convenience, roll the dough directly onto a parchment-lined baking sheet.

Use a heart-shaped cookie cutter to create shapes. Place the entire tray in the refrigerator for 30 minutes to firm up the dough.
Preheat the oven to 300°F (150°C). Carefully remove excess dough from around the shapes and spread the cookies slightly apart. Bake for 18–20 minutes, just until the edges turn lightly golden. For smaller shapes, reduce baking time. Allow cookies to cool completely.

Making The Icing

In a bowl, whisk egg whites and lemon juice on low speed until frothy.

Add powdered sugar half a cup at a time. Continue mixing until soft peaks form.
Increase the speed and add more sugar, a little at a time, until the icing reaches a thick, toothpaste-like consistency. This will be used for piping.
Divide the icing into small bowls and mix in food coloring until you achieve your desired shades.

Transfer a portion of the thick icing into a piping bag fitted with a No. 2 tip. Pipe a neat border around the edges of each cookie.
Add small amounts of water to the remaining icing until it thins out to a smooth, pourable texture. This should flow easily but not be too watery.
Spoon the runny icing inside the piped borders. Use the back of a spoon or a toothpick to spread it evenly.

Once the base icing is completely dry, use the reserved thick icing to pipe messages or designs onto the cookies.

Tips For Perfect Conversation Heart Cookies

Making shortbread cookies can be a fun and easy process with just a few simple tips. Here’s how you can make sure they turn out perfectly every time:

Use cold butter for the best texture. If the butter is too soft, the dough can spread too much while baking.

Chill the dough before cutting the cookies. This helps maintain their shape and prevents them from puffing up in the oven.
Don’t overmix the dough. Mix only until combined to keep the cookies tender.
Use a sharp cookie cutter to get clean edges, which helps make the cookies look even better.

Watch the baking time closely. Shortbread cookies can brown quickly, so keep an eye on them in the last few minutes of baking.

How To Properly Store Conversation Heart Cookies?

To keep your shortbread cookies fresh and tasty for longer, here are some easy storing tips:

Room temperature: Place the cookies in an airtight container, and they will stay fresh for up to a week.

Freezing: You can freeze the cookies by laying them flat in a container, separated with parchment paper. They’ll keep well for up to 3 months.
Avoid humidity: Make sure to store them in a cool, dry place away from heat and moisture to maintain their crispness.
