There are desserts that quietly satisfy a sweet craving, and then there are desserts that announce joy the moment you see them. Funfetti Shortbread Sandwich Cookies with Frosting fall proudly into the second category. With their buttery, tender shortbread texture, pops of colorful sprinkles, and a rich vanilla frosting tucked between two delicate cookies, these treats are pure celebration—no special occasion required.

These cookies combine the timeless elegance of classic shortbread with the playful nostalgia of funfetti. The result is a dessert that feels both sophisticated and whimsical, perfect for birthdays, baby showers, holidays, bake sales, or simply brightening an ordinary afternoon. Each bite melts in your mouth, delivering buttery richness balanced by sweetness and a creamy center that ties everything together.

Unlike traditional sugar cookies, shortbread relies on butter as the star, giving these sandwich cookies a delicate crumb and rich flavor. Adding sprinkles directly into the dough ensures that every cookie is colorful without compromising texture. The frosting is smooth, lightly sweet, and spreadable, making assembly easy while creating bakery-style results at home.

This recipe is designed to be approachable for home bakers while delivering professional-looking cookies. With simple ingredients, clear steps, and helpful tips, you’ll find yourself returning to this recipe again and again—especially when you need a dessert that looks as good as it tastes.

Ingredients

Cookie Dough

1 cup unsalted butter, softened
¾ cup powdered sugar
1 teaspoon vanilla extract
½ teaspoon salt
2 cups all-purpose flour
½ cup rainbow sprinkles (jimmies work best)

Frosting Filling

½ cup unsalted butter, softened
1½ cups powdered sugar
1 teaspoon vanilla extract
2–3 tablespoons cream or milk
Pinch of salt

Instructions

Prepare the Dough
In a large mixing bowl, beat the softened butter and powdered sugar until smooth, pale, and fluffy. This step is essential for achieving a tender shortbread texture.
Add Flavoring
Mix in the vanilla extract and salt until fully incorporated.
Incorporate the Flour
Gradually add the flour, mixing on low speed just until a soft dough forms. Avoid overmixing to keep the cookies tender.
Fold in Sprinkles
Gently fold in the rainbow sprinkles using a spatula, distributing them evenly throughout the dough.
Chill the Dough
Wrap the dough in plastic wrap and refrigerate for at least 30 minutes. Chilling helps prevent spreading and ensures clean edges.
Preheat and Prepare
Preheat your oven to 325°F (165°C). Line baking sheets with parchment paper.
Shape the Cookies
Roll the dough out on a lightly floured surface to about ¼-inch thickness. Use a round cookie cutter to cut out shapes and place them on prepared baking sheets.
Bake
Bake for 12–15 minutes, or until the bottoms are just lightly golden. Do not overbake—shortbread should remain pale.
Cool Completely
Transfer cookies to a wire rack and allow them to cool completely before frosting.
Make the Frosting
Beat the softened butter until creamy. Add powdered sugar, vanilla extract, salt, and cream one tablespoon at a time until smooth and spreadable.
Assemble the Sandwich Cookies
Spread or pipe frosting onto the flat side of half the cookies. Top with remaining cookies to form sandwiches, gently pressing together.

Tips for Perfect Shortbread Sandwich Cookies

Use room-temperature butter for smooth mixing and even texture
Choose jimmies over nonpareils, as they bleed less color
Chill before baking to keep cookies from spreading
Pipe frosting for bakery-style presentation
Match cookie sizes for neat, uniform sandwiches

Fun Variations to Try

Birthday Cake Version: Add almond extract to the dough and frosting

Chocolate Funfetti: Dip half of each assembled cookie in melted white or dark chocolate

Serving Suggestions

Storage and Make-Ahead Tips

Store assembled cookies in an airtight container for up to 4 days
Unfilled cookies can be frozen for up to 2 months
Frosting can be made a day ahead and refrigerated
