- For the Lemon Filling:1. In a medium saucepan, whisk together your lemon juice, lemon zest, sugar, and cornstarch until everything is nice and smooth. No lumps allowed here!
- 2. Now, add in those egg yolks and give it another good whisk until everything is beautifully combined.
- 3. Place the saucepan over medium heat. Keep whisking constantly! You'll notice it start to thicken up. This usually takes about 5–7 minutes. You're looking for a consistency that coats the back of a spoon.
- 4. Once it's thickened, take it off the heat. Stir in the butter until it's all melted and makes your filling wonderfully smooth and glossy.
- 5. Pour the filling into a bowl. To prevent a skin from forming, gently press a piece of plastic wrap directly onto the surface of the filling. Then, pop it into the refrigerator to cool completely.
- For the Cookies:6. Grab a large bowl and cream together your softened butter and sugar until the mixture is light and fluffy. This is key for tender cookies!
- 7. Add in your egg, vanilla extract, and that glorious lemon zest. Mix it all up until it's really well combined. The aroma is already amazing!
- 8. In a separate bowl, give your flour, baking powder, and salt a little whisk together. This ensures the leavening agent and salt are evenly distributed.
- 9. Now, gradually add the dry ingredients to your wet ingredients. Mix until a lovely dough forms. It should hold together nicely.
- 10. Divide your dough into two equal discs. Wrap them up snugly in plastic wrap and let them chill in the refrigerator for about 30 minutes. This makes the dough easier to handle.
- 11. Preheat your oven to 350°F (175°C). While the oven heats up, line your baking sheets with parchment paper. Parchment paper is a baker's best friend for preventing sticking!
- 12. Roll out your chilled dough to about ¼-inch thick. Use your favorite cookie cutters to cut out your shapes. Now, for the fun part: take half of your cookies and cut a small hole in the center – this is where our delicious filling will peek through!
- 13. Carefully place your cookies onto the prepared baking sheets. Bake them for about 10–12 minutes, or until they're just lightly golden around the edges. We don't want them too brown!
- 14. Let the cookies cool on the baking sheets for a couple of minutes before transferring them to a wire rack to cool completely. Patience is a virtue here, especially before filling!
- Assemble the Cookies:15. Once everything is cooled, it's time to bring these beauties together! Spread about 1 teaspoon of that wonderful lemon filling onto the bottom of one of your full cookies.
- 16. Gently place one of the "cut-out" cookies on top to create a lovely sandwich.
- 17. If you like a little extra flair, dust them with powdered sugar. It gives them that extra special touch, almost like a dusting of snow on a sunny day!
Notes
Want to put your own spin on these lemony delights? I love experimenting in the kitchen, and here are a few ideas! For the Filling: If you don't have cornstarch, you could try a similar amount of all-purpose flour, but cornstarch generally gives a smoother texture. You could also add a tiny drop of yellow food coloring to make the filling even brighter if you like. For the Cookies: Feel free to add a pinch of cinnamon or cardamom to the cookie dough for a warmer flavor profile. For a really decadent treat, try adding some white chocolate chips to the dough before chilling. Decorations: Instead of powdered sugar, you could make a simple glaze with powdered sugar and a little lemon juice. Or, for a fun twist, dip the edges of the filled cookies into some melted white chocolate! If you're a fan of lemon and berry flavors, you might enjoy my recipe for Strawberry Lemonade Cupcakes. Flavor Boost: A touch of almond extract in the cookie dough can add a lovely complementary flavor to the lemon.
