Follow these steps carefully to bake the perfect batch of Espresso Ricotta Shortbread. Precision in baking often leads to the best results!

1. Prepare the Ricotta: If your ricotta seems watery, line a fine-mesh sieve with a coffee filter or a double layer of cheesecloth. Place the ricotta in the sieve set over a bowl and let it drain in the refrigerator for at least 30 minutes, or even an hour, to remove excess moisture. Press gently to extract more liquid if needed. This step is crucial for the right dough consistency.
2. Combine Dry Ingredients: In a medium bowl, whisk together the all-purpose flour and salt. Set aside.
3. Cream Butter and Sugar: In a large bowl, using a stand mixer fitted with the paddle attachment or a hand mixer, beat the softened unsalted butter and granulated sugar together on medium speed until light and fluffy. This usually takes about 3-4 minutes. Scrape down the sides of the bowl occasionally to ensure even mixing. This step incorporates air, which contributes to the cookie’s texture.
4. Add Wet Ingredients: Add the well-drained ricotta cheese, instant espresso powder, egg yolk, and vanilla extract to the creamed butter and sugar mixture. Beat on low speed until just combined. Be careful not to overmix at this stage; you just want everything incorporated. The mixture might look slightly curdled due to the ricotta, which is normal.
5. Incorporate Dry Ingredients: Gradually add the flour mixture to the wet ingredients in two or three additions. Mix on low speed until the flour is just incorporated and a soft dough forms. Again, avoid overmixing, as this can develop too much gluten and result in tough cookies. The dough will be soft but should not be overly sticky if the ricotta was well-drained.
6. Chill the Dough (Crucial Step): Divide the dough in half. Shape each half into a flat disc, about 1-inch thick. Wrap each disc tightly in plastic wrap. Refrigerate for at least 2 hours, or preferably overnight. Chilling the dough is essential for several reasons: it allows the flour to hydrate, the flavors to meld, and most importantly, it solidifies the butter, which prevents the cookies from spreading too much during baking and makes the dough easier to handle.
7. Preheat Oven and Prepare Baking Sheets: When ready to bake, preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats. This prevents sticking and helps with even baking.
8. Roll and Cut: Lightly flour a clean work surface. Unwrap one disc of chilled dough (keep the other refrigerated). If the dough is very firm, let it sit at room temperature for 5-10 minutes to become slightly more pliable. Roll the dough out to approximately ¼ to ⅓ inch thickness. Use cookie cutters of your desired shape to cut out the shortbread. Reroll scraps gently and cut more cookies until all the dough is used. If the dough becomes too soft at any point, return it to the refrigerator for 15-20 minutes to firm up.
9. Arrange on Baking Sheets: Carefully transfer the cut-out cookies to the prepared baking sheets, leaving about 1 inch of space between them as they will spread slightly.
10. Chill Before Baking (Optional but Recommended): For extra sharp edges and to further prevent spreading, you can place the baking sheets with the cut-out cookies into the refrigerator or freezer for another 15-20 minutes before baking.
11. Bake: Bake in the preheated oven for 12-16 minutes, or until the edges are lightly golden brown and the centers are set. Baking time will vary depending on the thickness of your cookies and your oven’s quirks. Keep a close eye on them, as shortbread can go from perfectly baked to overdone quickly.
12. Cool: Let the cookies cool on the baking sheets for 5-10 minutes before carefully transferring them to a wire rack to cool completely. They will be delicate when warm but will firm up as they cool.
13. Decorate (Optional): Once completely cooled, you can dust the cookies with powdered sugar or drizzle them with melted dark chocolate if desired. Let any chocolate set before storing.
