Pastel Sugar Cookie Sandwiches

My kitchen counter looked like an explosion of Easter eggs the first time I attempted pastel buttercream. I had grand visions of soft mint greens and baby pinks, but somehow ended up with muddy teal and what my sister called 'bruised peach.' We ate them anyway, laughing through the imperfect colors, and I learned that gel food coloring requires a featherlight touch.

Last spring I made these for my daughter's classroom celebration and sent home extras with her teacher. She emailed me that evening asking for the recipe, mentioning her husband had already eaten three. Theres something impossibly nostalgic about sandwich cookies that brings out the kid in everyone.

Ingredients

• 2 ½ cups all-purpose flour: Spoon and level instead of scooping directly to avoid packing too much flour into your dough
• ½ teaspoon baking powder: Just enough to give the cookies a subtle lift without making them cakey
• ¼ teaspoon salt: Balances the sweetness and enhances vanilla flavor
• ¾ cup unsalted butter: Room temperature butter should give slightly when pressed but still hold its shape
• 1 cup granulated sugar: Cream this thoroughly with the butter for that melt-in-your-mouth texture
• 1 large egg: Bring to room temperature to prevent the dough from seizing up
• 1 teaspoon pure vanilla extract: Dont skimp here since vanilla is the primary flavor
• ½ cup unsalted butter for filling: Cold butter creates air pockets when beaten so start with room temperature
• 2 cups powdered sugar: Sifting prevents lumps that would make your buttercream grainy
• 1 ½ tablespoons milk: Add drop by drop until you reach your desired consistency
• 1 teaspoon pure vanilla extract: Use the same quality vanilla as in the cookie dough
• Pinch of salt: Cuts through the sweetness of the buttercream
• Pastel gel food coloring: Start with a toothpick amount and add gradually

Instructions

Whisk the dry ingredients:

Combine flour baking powder and salt in a medium bowl and set aside

Cream butter and sugar:

Beat on medium speed for 2 to 3 minutes until pale and fluffy scraping the bowl halfway through

Add egg and vanilla:

Mix until fully incorporated stopping to scrape down the sides of the bowl

Combine wet and dry:

Add the flour mixture gradually mixing just until no dry streaks remain

Chill the dough:

Divide in half flatten into discs wrap tightly and refrigerate for at least 30 minutes or until firm

Prepare for baking:

Preheat oven to 350°F and line baking sheets with parchment paper

Roll and cut:

Roll dough to ¼ inch thickness on a floured surface and cut with a 2-inch round cutter

Bake to perfection:

Bake for 8 to 10 minutes until edges are just beginning to turn golden then cool completely

Make the buttercream:

Beat butter until creamy then gradually add powdered sugar milk vanilla and salt until fluffy

Create pastel colors:

Divide buttercream among small bowls and tint each with a tiny amount of gel coloring

Assemble the sandwiches:

Spread buttercream on half the cookies and top with remaining cookies

Let them set:

Wait 20 minutes before serving so the filling firms up slightly

These have become my go-to when I need something that looks impressive but actually comes together in stages. The dough can be made ahead the filling waits patiently in the fridge and the assembly feels like play time instead of work.

Getting That Perfect Pastel Shade

Start with a toothpick dipped in gel coloring and add a single dot to your buttercream. Mix thoroughly and assess from there. Remember the color will deepen slightly as it sits so stop a shade lighter than your target.

Rolling Without Sticking

If your dough keeps sticking to the rolling pin try rolling between two sheets of parchment paper. You can also flip the dough onto the counter and peel off the top paper before cutting.

Making Them Ahead

The baked cookies freeze beautifully for up to a month and the buttercream can sit in the fridge for three days. Just bring everything to room temperature before assembling.

• Store assembled cookies in single layers separated by parchment paper
• These actually taste better on day two when flavors have melded
• A light sprinkling of edible glitter makes them feel extra festive

Theres nothing quite like biting into a cookie sandwich you made yourself. Happy baking.

Recipe FAQs

→ How long should I chill the cookie dough?

Refrigerate the dough for at least 30 minutes. This step prevents spreading during baking and makes rolling easier. For even better results, chill up to overnight—just let soften slightly before rolling.

→ Can I make these ahead of time?

Absolutely. The baked cookies can be stored in an airtight container for up to 3 days. You can also freeze undecorated cookies for up to 3 months. Fill shortly before serving for the freshest texture.

→ What's the best way to achieve pastel colors?

Use gel food coloring rather than liquid—start with a tiny amount on a toothpick and gradually increase until you reach your desired soft shade. Pastels require just a touch of color, so less is more.

→ Why did my cookies spread too much?

This usually happens when dough isn't chilled thoroughly or the butter was too soft before mixing. Ensure your butter is at room temperature but not melted, and don't skip the chilling step. Measuring flour accurately also helps.

→ Can I use different flavors?

Certainly. Swap vanilla extract for almond, lemon, orange, or coconut extract in either the cookies or filling. You can also add citrus zest to the dough for bright notes that complement the sweet buttercream beautifully.
