These pastel sugar cookie sandwiches bring a burst of color and sweetness to any occasion. The tender, crackly cookies paired with silky vanilla filling create a dessert that's as beautiful as it is delicious. I've made these countless times for birthday parties, baby showers, and whenever I need a cheerful treat to brighten someone's day.
These cookies have become my signature dessert for springtime gatherings. My niece once declared them "too pretty to eat" before promptly devouring three in one sitting.
Ingredients
- FOR THE SUGAR COOKIES
- Unsalted butter: softened to room temperature for the perfect texture
- Granulated sugar: creates that classic crackly top
- Large egg: binds everything together
- Vanilla extract: provides that warm familiar flavor
- All purpose flour: use unbleached for best results
- Baking soda and baking powder: the perfect leavening combination
- Salt: enhances all the flavors
- Milk: adds moisture without thinning the dough too much
- Gel food coloring: produces vibrant colors without changing consistency
- FOR THE VANILLA FILLING
- Unsalted butter: softened for maximum creaminess
- Powdered sugar: sifted for a smooth texture
- Heavy cream: creates that melt in your mouth quality
- Vanilla extract: choose pure not imitation for best flavor
- Salt: balances the sweetness perfectly
Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to 350°F and line baking sheets with parchment paper. An accurately preheated oven ensures even baking and those characteristic sugar cookie cracks.
- Cream Butter and Sugar:
- Beat the butter and sugar together until extremely light and fluffy, about 2 full minutes. This step incorporates air and creates the foundation for a tender cookie. The mixture should look almost whipped and significantly lighter in color.
- Add Wet Ingredients:
- Mix in the egg and vanilla until fully incorporated. Make sure to scrape down the sides of the bowl to ensure everything is evenly mixed. The mixture should look smooth and silky.
- Add Dry Ingredients:
- Gradually incorporate the whisked dry ingredients on low speed. This prevents flour from flying everywhere and ensures even mixing. The dough will look thick and slightly sticky at this stage.
- Add Milk and Color:
- Mix in the milk until the dough becomes soft but manageable. Divide the dough into five equal portions and work the gel coloring into each one. Knead gently but thoroughly until the color is completely uniform with no streaks.
- Shape and Bake:
- Roll tablespoon sized portions into perfect spheres between your palms. The smoother the ball, the more even the cookie. Space them well apart as they will spread during baking. Bake until the edges are set but the centers still look slightly underdone for that perfect soft texture.
- Make the Filling:
- Beat the butter until extremely smooth before gradually adding powdered sugar. This prevents lumps and creates a silky texture. Add the remaining ingredients and whip until the filling looks light and fluffy, about 3 minutes of mixing.
- Assemble Cookie Sandwiches:
- Match cookies of similar size and shape for the most professional looking result. Pipe or spread a generous amount of filling on one cookie before gently pressing the second cookie on top. Apply even pressure to distribute the filling to the edges.

The vanilla filling is my absolute favorite part of these cookies. I often catch myself making a little extra just so I can sneak a spoonful while assembling. My daughter always knows when I've done this because I inevitably end up with a telltale smudge of buttercream on my apron.
Color Techniques
The key to achieving perfect pastel colors is starting with just a tiny amount of gel coloring. Dip a toothpick into the gel color and then into your dough, then knead thoroughly before adding more. This gradual approach prevents oversaturated colors that can look artificial. For the most cohesive presentation, stick with colors in the same tonal family rather than mixing primary and pastel shades.

Make Ahead Instructions
These cookie sandwiches actually improve with a little rest time. The filling slightly softens the cookies, creating a perfect tender bite. You can make the cookie dough up to 48 hours ahead and refrigerate it tightly wrapped. Just bring it back to room temperature before coloring and shaping. Fully assembled cookie sandwiches can be stored in airtight containers with parchment between layers to prevent sticking. For gifting, place each sandwich in a small cellophane bag tied with coordinating ribbon.
Serving Suggestions
These colorful treats shine as the centerpiece of a dessert table. Arrange them in a spiral pattern on a white cake stand for maximum visual impact. They pair beautifully with tea, coffee, or a glass of cold milk. For special occasions, match the cookie colors to your event theme or season. Yellow and lavender for spring, blues and greens for baby boy showers, or pinks and purples for little girl birthdays.
Troubleshooting Tips
If your cookies spread too much during baking, your butter might have been too warm. Pop the remaining dough in the refrigerator for 15 minutes before continuing. For cookies that come out too thick or puffy, gently tap the baking sheet on the counter immediately after removing from the oven to help them settle. If your filling seems too stiff, add cream a half teaspoon at a time until you reach the desired consistency.
Frequently Asked Questions
- → How can I achieve pastel colors in the cookies?
Use gel food coloring to tint each portion of the dough. Gel colors provide vibrant pastel shades without altering the texture of the dough.
- → What can I use if I don't have gel food coloring?
If gel food coloring is unavailable, you can use liquid food coloring, but use it sparingly to avoid changing the dough consistency.
- → Can I make the filling in advance?
Yes, you can prepare the vanilla filling ahead of time. Store it in an airtight container in the refrigerator and bring it to room temperature before assembling the sandwiches.
- → How do I store the cookie sandwiches?
Store the cookie sandwiches in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. Allow chilled cookies to come to room temperature before serving for the best texture.
- → What is the best way to assemble the sandwiches?
Match cookies of similar size, then spread a generous amount of filling on the flat side of one cookie. Top with another cookie and press gently to distribute the filling evenly.
