Directions
<ol class="no-list-style"> <li class="MethodStepper"> <h4 class="step-title">Step 1</h4> Preheat your oven to 180°C and line two baking sheets with parchment paper. In a medium bowl, whisk together the flour, cocoa powder, espresso powder, baking soda, and salt until well combined. The espresso powder not only adds flavor but also enhances the chocolate notes in the cookies. </li> <li class="MethodStepper"> <h4 class="step-title">Step 2</h4> In the bowl of your stand mixer fitted with the paddle attachment, cream the butter and both sugars on medium-high speed for 3-4 minutes until light and fluffy. This extended creaming creates air pockets that help give structure to your cookies. The mixture should lighten in color and increase in volume. </li> <li class="MethodStepper"> <h4 class="step-title">Step 3</h4> Add the egg and vanilla extract to the butter mixture and beat until fully incorporated, scraping down the sides of the bowl as needed. The mixture should look smooth and glossy. </li> <li class="MethodStepper"> <h4 class="step-title">Step 4</h4> With the mixer on low speed, gradually add the dry ingredients to the wet ingredients, mixing just until combined. Be careful not to overmix, which can develop the gluten in the flour and result in tough cookies. The dough will be fairly stiff but should hold together when pressed. </li> <li class="MethodStepper"> <h4 class="step-title">Step 5</h4> Divide the dough in half, form each half into a disk, and wrap in cling film. Refrigerate for at least 30 minutes. Chilling the dough firms up the butter, preventing the cookies from spreading too much during baking and intensifying the flavor. </li> <li class="MethodStepper"> <h4 class="step-title">Step 6</h4> On a lightly floured surface, roll out one disk of dough to about 5mm thickness. Use your cookie cutter to cut out rounds and transfer them to the prepared baking sheets, leaving about 3cm between each cookie. Gather the scraps, reroll, and cut out more cookies. Repeat with the second disk of dough. </li> <li class="MethodStepper"> <h4 class="step-title">Step 7</h4> Bake the cookies for 10-12 minutes, rotating the pans halfway through. The cookies should be set around the edges but still slightly soft in the center—they'll firm up as they cool. Look for a matte finish on top rather than shiny patches, which would indicate they're underbaked. </li> <li class="MethodStepper"> <h4 class="step-title">Step 8</h4> Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to wire racks to cool completely. The cookies need to be completely cool before filling, or the buttercream will melt. </li> <li class="MethodStepper"> <h4 class="step-title">Step 9</h4> While the cookies cool, prepare the espresso buttercream. In the clean bowl of your stand mixer, beat the softened butter on medium speed until creamy and pale, about 2 minutes. This creates the base for a smooth, light filling. </li> <li class="MethodStepper"> <h4 class="step-title">Step 10</h4> Gradually add the sifted powdered sugar, about 60g at a time, mixing on low speed until incorporated after each addition. Sifting the sugar ensures a silky-smooth buttercream without any lumps. </li> <li class="MethodStepper"> <h4 class="step-title">Step 11</h4> Add the dissolved espresso, heavy cream, vanilla extract, and salt. Beat on medium speed for 3-4 minutes until the buttercream is light and fluffy. If the buttercream is too thick, add a teaspoon of heavy cream; if too thin, add a tablespoon of powdered sugar. </li> <li class="MethodStepper"> <h4 class="step-title">Step 12</h4> To assemble the sandwich cookies, turn half of the cooled cookies upside down. Either pipe or spread about 1 tablespoon of buttercream onto each upside-down cookie, then top with another cookie, right side up, pressing gently to spread the filling to the edges. </li> <li class="MethodStepper"> <h4 class="step-title">Step 13</h4> Allow the assembled cookies to rest for about 30 minutes so the filling can set. This resting period also allows the flavors to meld together, creating a more harmonious taste experience. The cookies will keep in an airtight container at room temperature for up to 3 days, or refrigerated for up to a week (bring to room temperature before serving for the best flavor and texture). </li> </ol>
