Pastel Sugar Cookie Sandwiches

The first time I made these pastel sandwich cookies was for my niece's spring birthday party. I'd planned to make simple sugar cookies, but something about the rainy April morning made me want to add color and whimsy. When she saw the tray of pink, yellow, and blue sandwiches, her eyes lit up like I'd handed her a rainbow.

Last spring I made these for a baby shower and the mom-to-be cried when she saw them. She said they reminded her of the cookies her grandmother used to make, but with a modern twist that felt perfect for celebrating new beginnings. The pastel colors became the centerpiece of the whole dessert table.

Ingredients

• 2 ½ cups all-purpose flour: I've learned that weighing the flour makes a huge difference in texture, preventing cookies from spreading too thin
• ½ teaspoon baking powder: This small amount gives just the right lift without making the cookies cakey or puffy
• ¼ teaspoon salt: Don't skip this, it balances the sweetness and makes the vanilla flavor pop
• ¾ cup unsalted butter, room temperature: I always leave mine out overnight because properly softened butter incorporates air beautifully for a tender cookie
• 1 cup granulated sugar: Creaming this thoroughly with the butter creates those delicate crisp edges we want
• 1 large egg: Bring this to room temperature too, or it won't emulsify properly with the butter
• 1 teaspoon pure vanilla extract: Splurge on the good stuff here since vanilla is the star flavor
• ½ cup unsalted butter for filling: Again, room temperature is non-negotiable for silky smooth buttercream
• 2 cups powdered sugar, sifted: Sifting prevents lumps and makes the frosting impossibly smooth
• 1 ½ tablespoons milk: Add this gradually until you reach your perfect spreading consistency
• Pastel gel food coloring: Gel colors are more concentrated than liquid, so start with a tiny toothpick drop

Instructions

Whisk the dry foundation:

In a medium bowl, combine the flour, baking powder, and salt until everything is evenly distributed. I like to use a whisk instead of a sifter because it's faster and still aerates the flour beautifully.

Cream butter and sugar until pale and fluffy:

Beat the butter and sugar on medium speed for a full 2 to 3 minutes, stopping to scrape down the bowl halfway through. The mixture should look noticeably lighter and feel like whipped cream.

Add the egg and vanilla:

Crack in the egg and pour in the vanilla, mixing for another minute until the batter looks glossy and smooth. If you see any butter streaks, keep mixing.

Incorporate the flour gently:

Turn the mixer to low and gradually add the dry ingredients, mixing just until you no longer see white flour streaks. Overmixing at this stage makes tough cookies, so stop as soon as it comes together.

Chill the dough:

Divide the dough in half, press each piece into a flat disc, and wrap tightly in plastic. Refrigerate for at least 30 minutes, though I've found that an hour makes rolling even easier.

Preheat your oven:

Heat the oven to 350°F and line two baking sheets with parchment paper. I reuse my parchment sheets for both batches, just let them cool slightly between batches.

Roll and cut the cookies:

On a lightly floured surface, roll one disc to ¼ inch thickness, rotating the dough frequently to prevent sticking. Cut rounds with a 2-inch cutter and place them 1 inch apart on the prepared sheets.

Bake until barely golden:

Bake for 8 to 10 minutes, watching closely after the 8-minute mark. You want the edges to just start turning pale golden while the centers still look slightly soft.

Cool completely:

Let the cookies rest on the baking sheets for 2 minutes, then transfer to a wire rack. They must be completely cool before filling or the buttercream will melt right off.

Make the buttercream:

Beat the butter until creamy, then gradually add the powdered sugar, milk, vanilla, and pinch of salt. Whip on medium-high speed for 2 minutes until the frosting is light and fluffy.

Create pastel magic:

Divide the buttercream into 3 or 4 small bowls and add a tiny amount of gel food coloring to each. Mix thoroughly, adding more color drop by drop until you reach soft pastel shades.

Assemble the sandwiches:

Spread a generous layer of buttercream on the flat side of half the cookies, then top with remaining cookies. I like to vary the colors so each sandwich has two different pastel sides.

Let them set:

Allow the assembled cookies to sit at room temperature for 20 minutes. This lets the buttercream firm up slightly so they're easier to handle and transport.

Save

My daughter now asks to help make these every Easter, and I've learned to accept that half the sprinkles end up on the floor and her fingers inevitably turn blue from the food coloring. The messy kitchen is worth it when she proudly presents the platter to guests like she created a masterpiece.

Making Ahead

You can prepare the dough up to 3 days in advance and keep it tightly wrapped in the refrigerator. The baked cookies also freeze beautifully for up to a month, though I recommend filling them after thawing for the best texture.

Color Variations

Beyond traditional pastels, try coordinating colors with seasons. Deep red and green for Christmas, orange and yellow for fall gatherings, or stick to monochromatic shades using different intensities of a single color for an elegant wedding shower dessert.

Serving Suggestions

These sandwiches shine when displayed on a vintage cake stand or arranged by color on a white platter. They're substantial enough to stand alone, but I love serving them with fresh strawberries or alongside vanilla bean ice cream for an extra special dessert course.

• Arrange them in a rainbow pattern on the platter for maximum visual impact
• Dust lightly with edible glitter for holiday sparkle
• Package individually in clear bags tied with ribbon for thoughtful party favors

There's something deeply satisfying about biting through that crisp buttery cookie into the cloud-soft filling, like a little moment of joy that feels both nostalgic and brand new.

Questions & Answers

→ How far in advance can I make these?

You can prepare the cookie dough up to 3 days ahead and store it wrapped in the refrigerator. The assembled sandwiches stay fresh at room temperature for up to 3 days in an airtight container, making them perfect for preparing a day before your event.

→ Can I freeze the dough or assembled cookies?

Yes, freeze the cookie dough discs for up to 3 months. Thaw overnight in the refrigerator before rolling and baking. Assembled cookies can also be frozen for up to 2 months—just wrap individually or layer with parchment paper in a freezer-safe container.

→ What other fillings work well?

Beyond classic vanilla buttercream, try adding lemon curd, raspberry jam, chocolate ganache, or cream cheese frosting. You can also flavor the buttercream with almond extract, mint extract, or freeze-dried fruit powder for variety.

→ Why did my cookies spread too much?

This usually happens when the dough becomes too warm. Always chill the dough for at least 30 minutes before rolling and baking. If your kitchen is warm, rechill the cutouts on the baking sheet for 10 minutes before popping them in the oven.

→ How do I achieve the perfect pastel colors?

Use gel food coloring rather than liquid, as it provides vibrant color without thinning the buttercream. Start with a tiny amount on a toothpick—you can always add more. For soft pastels, aim for 1-2 drops per bowl of frosting.

→ Can I make these without a cookie cutter?

Absolutely. Use a drinking glass with a 2-inch opening, or simply roll the dough into small balls and flatten slightly with the bottom of a glass. The shapes might vary slightly but will still taste delicious.
