👨‍🍳 Step-by-Step Instructions:

Step 1: Preheat the Oven

• Preheat your oven to 325°F (165°C) .
• Line two baking sheets with parchment paper.

Step 2: Cream the Butter and Sugar

• In a large mixing bowl, add softened butter and powdered sugar .
• Using a hand mixer or stand mixer, beat on medium speed until light and fluffy — about 2–3 minutes .

💡 Tip: Make sure the butter is at room temperature for smooth blending.

Step 3: Add Flavoring

• Mix in vanilla extract (if using).
• Scrape down the sides of the bowl with a spatula to ensure everything is well combined.

---

Step 4: Add Dry Ingredients

• Gradually mix in flour and salt on low speed until just combined.
• Do not overmix — the dough will be crumbly but should hold together when pressed.

---

Step 5: Shape the Dough

• Turn the dough out onto a lightly floured surface.
• Gently press or roll it into a ball, then divide into two equal portions.

Pro Tip: For uniform cookies, use a cookie scoop (about 1 tbsp per ball), roll into balls, and place on prepared baking sheets.

Step 6: Bake the Cookies

• Flatten each ball slightly with the palm of your hand or the bottom of a glass dipped in sugar.
• Bake one sheet at a time for 15–18 minutes , or until the edges are lightly golden.

❗ Do not overbake — shortbread should stay pale with just a hint of color.

Step 7: Cool the Cookies

• Let the cookies cool on the baking sheet for 5 minutes , then transfer to a wire rack to cool completely (about 30 minutes ).

---

Step 8: Prepare the Filling

• While the cookies cool, prepare your filling:
  • Spread jam or jelly on the flat side of one cookie.
  • Top with a second cookie to form a sandwich.

🔄 Alternative Fillings:

• Whipped cream + fresh berries
• Chocolate hazelnut spread
• Buttercream frosting
• Lemon curd

Step 9: Finish & Serve

• Optional: Dust the top of the sandwiches lightly with powdered sugar for a more elegant look.
• Store in an airtight container for up to 5 days , or freeze unfilled cookies for up to 1 month .
