Lemon sugar cookie sandwiches with raspberry buttercream make a bright, cheerful treat for a spring table, birthday tray, or afternoon cup of tea. The cookies are soft in the middle with lightly golden edges, scented with fresh lemon zest. Between each pair sits a tart-sweet raspberry filling made from freeze-dried berries, so it tastes like fruit rather than food coloring.
The cookies need a short chill before rolling, which helps the cut rounds keep their shape in the oven. Plan on about 90 minutes total, including cooling, and you will have 12 generously filled sandwiches. If you like a little contrast in a dessert, the lemon cookie and berry buttercream balance each other beautifully.
Why You’ll Love These Lemon Sugar Cookie Sandwiches with Raspberry Buttercream
This recipe pairs two flavors that are easy to recognize but feel a little more special together. Lemon zest perfumes the dough without making it sour, and a spoonful of lemon juice keeps the sweetness lively. The raspberry buttercream gets its color and flavor from finely ground freeze-dried raspberries, so there is no extra moisture to loosen the filling.
- Soft and tender: The dough is rolled just thick enough to stay soft after baking.
- Real berry flavor: Freeze-dried raspberries make a vivid, tangy filling without artificial coloring.
- Good make-ahead steps: Bake the cookies a day early and fill them when you are ready to serve.
- Easy to customize: Cut the cookies into rounds, hearts, or scalloped shapes to fit the occasion.
Ingredients You’ll Need
For the lemon sugar cookies
- 2¾ cups all-purpose flour, spooned and leveled
- ½ teaspoon baking powder
- ½ teaspoon fine salt
- 1 cup unsalted butter, softened
- 1 cup granulated sugar
- 1 large egg, at room temperature
- 1 large egg yolk, at room temperature
- 1 tablespoon finely grated lemon zest (from about 2 lemons)
- 1 tablespoon fresh lemon juice
- 1 teaspoon vanilla extract
For the raspberry buttercream
- 1 cup unsalted butter, softened
- 3½ cups powdered sugar, sifted
- 1 ounce freeze-dried raspberries, ground to a fine powder
- 1 teaspoon vanilla extract
- 1 to 2 tablespoons heavy cream or milk
- Pinch of fine salt
Use softened butter that yields slightly when pressed but does not look shiny or melted. If your freeze-dried berries have a few seeds, sift the powder through a fine mesh sieve before mixing it into the frosting.
How to Make Lemon Sugar Cookie Sandwiches with Raspberry Buttercream
- Whisk the dry ingredients. In a medium bowl, combine the flour, baking powder, and salt. Set it aside while you mix the butter and sugar.
- Cream the butter and sugar. In a large bowl, beat the softened butter and granulated sugar with a hand mixer on medium speed for about 2 minutes, until creamy and a shade lighter. Scrape down the bowl once.
- Add the egg and lemon. Beat in the egg and yolk until smooth. Mix in the lemon zest, lemon juice, and vanilla. The mixture may look slightly curdled from the juice; it will come together when the flour is added.
- Make and chill the dough. Add the dry ingredients in two additions and mix on low just until a soft dough forms. Divide it into two disks, wrap, and refrigerate for 30 to 45 minutes. The dough should be cool and easy to roll, not rock-hard.
- Heat the oven and roll. Heat the oven to 350°F and line two baking sheets with parchment. On a lightly floured counter, roll one disk to about ¼-inch thick. Cut 2½-inch rounds and place them 1 inch apart on the sheets. Gather and reroll scraps once.
- Bake the cookies. Bake for 9 to 11 minutes, rotating the sheet halfway through. Take them out when the edges are set but still pale; the bottoms should be only lightly golden. Cool on the sheet for 5 minutes, then transfer to a rack to cool completely.
- Make the raspberry buttercream. Beat the softened butter for 1 minute until fluffy. Add the powdered sugar in two additions on low speed, then beat in the raspberry powder, vanilla, and salt. Add cream a teaspoon at a time until the frosting is thick but pipeable. Beat for another minute to make it airy.
- Fill and sandwich. Turn half the cooled cookies bottom-side up. Pipe or spread about 1½ tablespoons buttercream over each. Top with the remaining cookies and press gently until the filling reaches the edges without squeezing out.
Let the assembled cookies sit for 20 minutes before serving so the buttercream can settle. For neat edges, use a small offset spatula or piping bag and keep the filling about â…› inch from the edge before sandwiching.
Tips and Variations
Keep the cookies tender
Measure flour by spooning it into the measuring cup and leveling the top. Scooping directly from the bag packs in too much flour and can make the cookies dry. Mix only until the dough comes together, and avoid adding extra flour while rolling; a lightly dusted counter is enough.
Adjust the lemon and berry balance
For a brighter lemon flavor, add another teaspoon of zest to the dough. If you prefer a softer raspberry note, begin with ¾ ounce of berry powder and add more after tasting. Do not add fresh raspberries to the frosting; their moisture can make the filling runny.
Try a different shape or finish
- Heart-shaped: Use a small heart cutter and chill the cut cookies for 10 minutes before baking.
- Extra tart: Spread a very thin layer of raspberry jam beneath the buttercream.
- White chocolate: Drizzle the tops with melted white chocolate once the sandwiches are filled.
- Mini cookies: Use a 1½-inch cutter and reduce the baking time to 7 to 9 minutes.
For another citrus-and-berry bake, see the site’s lemon raspberry swirl cookies. If you like decorating cut-out cookies, soft Easter sugar cookies use a similar cheerful approach. The lemon curd frosting is another way to bring citrus into a dessert, and a raspberry white chocolate muffin makes a sweet companion for brunch.
Storage and Freezing
Store filled sandwiches in an airtight container in the refrigerator for up to 4 days because the buttercream contains dairy. Let them sit at room temperature for 15 to 20 minutes before serving so the cookie softens and the filling loses its chill. If you prefer to make them ahead, keep the baked cookies in an airtight container at room temperature for up to 3 days and refrigerate the buttercream separately; fill them the day you plan to serve.
Unfilled cookies freeze well for up to 2 months. Place parchment between layers in a freezer-safe container and thaw while still covered to prevent condensation. Buttercream can also be frozen for about a month; thaw overnight in the refrigerator, then beat briefly to restore its fluffy texture. For safe handling, refrigerate filled cookies promptly and follow the FoodSafety.gov guidance for chilling perishable foods.
Frequently Asked Questions
Can I make lemon sugar cookie sandwiches with raspberry buttercream ahead?
Yes. Bake the cookies up to 3 days ahead and store them unfilled at room temperature. Make the buttercream up to 2 days ahead and refrigerate it. Let the frosting soften, beat briefly, and assemble the sandwiches a few hours before serving.
Can I use fresh raspberries in the buttercream?
Fresh berries add too much moisture and can thin the filling. Freeze-dried raspberries provide concentrated flavor and color without changing the buttercream texture. A small spoonful of seedless raspberry jam is fine as a thin layer between the cookies.
Why did my sugar cookies spread?
The butter may have been too warm, or the dough may not have chilled long enough. Chill the disks until cool and firm, and place cut cookies on a cool baking sheet. If the kitchen is warm, chill the cut rounds for 10 minutes before they go into the oven.
Do I need to sift the freeze-dried raspberry powder?
Sifting is helpful if your berries leave coarse seeds or small pieces. A fine powder blends evenly and gives the buttercream a smooth texture. Use a food processor or clean coffee grinder to pulverize the berries.
Can I tint the cookie dough pastel colors?
You can, but the lemon zest and raspberry filling already give the sandwiches a bright look. If you tint the dough, use a small amount of gel food coloring so the dough does not become sticky.
