Cream Cookie Sandwich Recipe

Prep

Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats. Measure and have ingredients ready.

Whisk together the dry ingredients: in a medium bowl combine 2 cups all-purpose flour, 1 tablespoon unsweetened cocoa powder, 1 teaspoon baking soda, and 1/2 teaspoon salt. Set aside.

Cream the fats and sugars: in a large bowl or the bowl of a stand mixer fitted with the paddle attachment, beat 3/4 cup softened unsalted butter, 1 cup granulated sugar, and 1/2 cup packed light brown sugar on medium speed until light and fluffy, about 2 to 3 minutes.

Add egg and vanilla: beat in 1 large egg until incorporated, then add 1 teaspoon vanilla extract and mix until smooth.

Combine wet and dry: with the mixer on low speed, gradually add the dry mixture to the butter mixture until just combined. Do not overmix.

Portion cookies: using a tablespoon or small cookie scoop (about 1 tablespoon per cookie), drop rounded portions of dough onto the prepared baking sheets, spacing them about 2 inches apart. For sandwich cookies, make about 24–28 small rounds (12–14 sandwiches).

Bake: bake in the preheated oven for 9–11 minutes, until edges are set and centers are slightly soft. The cookies will firm as they cool. Rotate sheets halfway through if needed.

Cool: remove from oven and let cookies cool on the sheet for 3–4 minutes, then transfer to a wire rack to cool completely. Ensure cookies are fully cooled before assembling sandwiches to prevent filling from melting.

Beat fats: in a clean large bowl or stand mixer bowl, beat 1/2 cup softened unsalted butter and 1/4 cup shortening (if using) on medium speed until smooth and creamy, about 1 minute.

Add powdered sugar gradually: reduce mixer speed to low and add 2.5 cups powdered sugar in three additions, mixing until incorporated after each addition to avoid a sugar cloud. Scrape down the bowl as needed.

Add flavor and adjust texture: add 1 teaspoon vanilla extract, 2 tablespoons heavy cream, and 1/8 teaspoon salt. Beat on medium-high for 1 to 2 minutes until the filling is light, airy, and spreadable. If the filling is too stiff, add additional cream 1 teaspoon at a time; if too soft, add a little more powdered sugar (1–2 tbsp) until desired consistency is reached.

Taste and adjust: taste and adjust salt or vanilla to balance sweetness. The filling should hold shape but be easy to pipe or spread.

Pair cookies: match cooled cookies into like-sized pairs so sandwiches are even.

Fill cookies: transfer the cream filling to a piping bag fitted with a round tip or use a spoon. Pipe or spoon about 1 to 1.5 tablespoons of filling onto the flat side of one cookie, then top with its matching cookie and press gently to spread filling to the edges. Repeat until all sandwiches are assembled.

Optional drizzle or dip: if using melted chocolate, drizzle or dip the tops of sandwiches. To drizzle, melt 1/4 cup chocolate gently and use a spoon to create thin lines over the sandwiches. Allow chocolate to set at room temperature or chill briefly (5–10 minutes).

Optional sea salt: sprinkle a light pinch (about 1/8–1/4 tsp distributed over several sandwiches) of sea salt flakes on the chocolate before it sets for contrast.

Serve or store: serve immediately or store in an airtight container at room temperature for up to 3 days, or refrigerate for up to 1 week. If refrigerated, bring to room temperature 15–30 minutes before serving for best texture.
