I’m not sure why or how these lemon shortbread cookies came into my life, but they’ve been in my Christmas baking rotation for years. They’re a welcome change from the heavy, rich desserts of the holiday season, while still feeling very festive, thanks to the contrast between the white chocolate and pops of green from the pistachios.
These cookies are made with a classic shortbread base, infused with a bright and tangy lemon flavour that comes from the addition of both lemon zest and juice. While you can make these into any shape you like, clearly, I’m quite partial to stars. They keep well, travel nicely in tins, and make a lovely edible gift — if you can bear to part with them, that is.
Chocolate Tips 🍫
Choosing the Right Chocolate
I recommend using a high-quality bar of real white chocolate. Choose a brand like Nestle Plaistowe, Lindt, or just about any European-made chocolate. Avoid chocolate chips, chocolate melts, or anything labelled as “compound chocolate” which contain stabilisers and vegetable fats. These won’t melt into the same, silky, smooth texture as real white chocolate — and they often taste too sweet and artificial.
The best method for melting chocolate
White chocolate is a very delicate creature. Due to its low melting point, it’s incredibly sensitive to heat and more prone to scorching than milk or dark chocolate. And if even a single drop of water sneaks in, it can seize up instantly, leaving you with a clumpy, unusable mess. Now that I’ve successfully scared you into submission, here’s the best way to melt it.
For this recipe, I stand by the microwave as the quickest and most reliable method. When working with small amounts of chocolate (I’m talking a couple hundred grams or so), the microwave gives you much better control than a double boiler while also keeping moisture safely out of the way. The key is to heat in short bursts, no longer than 30-seconds at a time, with a quick stir in between. So much easier than fiddling with pots of simmering water.
How to dip like a pro
- Cool cookies completely – If the cookies are still warm, the chocolate will slide right off. Let them come to room temperature first.
- Use a small, deep bowl – You need good depth to ensure to you can submerge your cookies halfway. If the chocolate level drops too much, try tilting the bowl to pool it to one side. Or as a last resort, spoon the chocolate over the cookies, coating it to the halfway point.
- Check the consistency – Your chocolate should be smooth, silky, and on the runny side. If it’s too stiff, stir in a tiny bit of neutral oil to loosen it. If it starts to thicken again as it cools, pop it back in the microwave for 10-15 seconds.
- Get rid off excess chocolate – After dipping, hold the cookie above the bowl for a few seconds to let the excess chocolate run off.
- Decorate before the chocolate sets – Add the pistachios while the chocolate is still wet to ensure they stay in place.
What You’ll Need
This shortbread follows the traditional Scottish formula of 3 parts flour, 2 parts butter, and 1 part sugar (by weight). It’s the same base recipe that I use for my Fairy Shortbread, just without the egg yolk. And of course, with lots of lemon!
- Butter: this needs to be softened to room temperature. I typically use unsalted butter, but salted works too — just leave out the added salt in the recipe. Most importantly, choose a good quality butter. New Zealand or European butters are usually the best for baking thanks to their higher fat content and richer flavour.
- Icing sugar (AKA powdered sugar) — the best sugar for a tender, melt-in-your-mouth shortbread. Make sure to sift it first to remove any lumps!
- Vanilla extract: it might seem counterintuitive to add vanilla to a lemon cookie, but it helps to soften the sharpness of the citrus and rounds out the overall flavour.
- Lemon zest + juice: lemon zest adds an aromatic citrus-y note, while lemon juice adds a subtle tang.
- Plain flour: use regular, all-purpose flour and measure carefully to avoid a dry dough.
- Salt: just a pinch makes the lemon flavour pop.
- White Chocolate: break or chop your chocolate into small pieces so that it melts evenly. As for the best white chocolate to use, see my chocolate tips above.
- Pistachios: I like to buy unshelled purely for convenience. I also prefer mine unsalted, but salted will work too, especially if you’re a fan of the sweet-and-salty combo.

How to Make Lemon Shortbread Cookies
1. Cream the butter and sugar – Place the softened butter and sifted icing sugar into a bowl. Using a handheld mixer or stand mixer, beat for about 2 to 3 minutes until pale and creamy.
2. Add flavourings – Add in the lemon zest and juice, followed by the vanilla extract. Beat until combined, and scrape down the sides of the bowl as needed to make sure everything is incorporated.
3. Mix in the flour – With the mixer on low-speed, add the salt, then gradually add the flour. It will look a little dry or sandy at first — just keep mixing until it starts to clump together, forming a rough dough.
4. Roll and cut – You can roll your dough out either on a lightly-floured work surface or between two pieces of parchment paper. Bring the crumbly dough together with your hands until it forms a cohesive ball, then flatten it into a disc. Roll the disc out to about 0.6 cm (1/4 in) thick. Punch out shapes with a floured cookie cutter, then carefully transfer the cookies to a lined baking sheet, leaving at least a 2-3 cm (1 in) gap between each. Gather the scraps, re-roll, and cut more cookies as needed. Chill for 30 minutes in the fridge to prevent spreading. While you wait, preheat your oven to 160°C (140°C/325°F).
5. Bake the cookies – Remove the chilled cookies from the fridge and bake for about 15-18 minutes on the middle rack. The exact time will depend on the size and shape of your cookies. Keep a close eye on them and remove when they’re just beginning to turn lightly golden around the edges. They might look a little underdone in the centre, but they’ll firm up as they cool. Leave them on the baking sheet for 5 minutes, then transfer to a wire cooling rack. Allow to cool completely before decorating.
6. Melt the chocolate – Place the white chocolate pieces into a small microwave-safe bowl and heat for 30 seconds at a time, giving it a stir in between bursts. White chocolate scorches easily, so be careful not to heat for longer stretches. Continue until the chocolate is just melted — if a few small lumps remain, continue stirring and these should melt from the residual heat. If the chocolate feels too thick for dipping, you can stir in a neutral-flavoured oil (such as vegetable oil) one tsp at a time to help thin it out.
7. Dip and decorate – Before you begin, line a couple of baking sheets with parchment paper or silicone mats. Dip each cookie halfway into the white chocolate, lift it out and allow any excess chocolate to drip off. Place carefully on the baking sheet and sprinkle chopped pistachios over the wet chocolate. Once all the cookies have been dipped, place them in the fridge until the chocolate has hardened (about 15 minutes).

Equipment
- hand mixer, or stand mixer with the whisk attachment
- rolling pin
- 5-7 cm (2-3 in) cookie cutter
- baking sheet(s)
Ingredients
- 170 g (⅔ cup) butter, softened
- 85 g (½ cup) icing sugar, sifted
- 1 tsp vanilla extract
- 2 tsp lemon zest, tightly packed
- 2 tsp lemon juice, freshly squeezed
- 260 g (2 cups) plain flour, spooned and levelled if using cups
- ¼ tsp salt
- 200 g (7 oz) white chocolate, chopped or broken into small pieces
- 2 tbsp shelled pistachios, finely chopped
Instructions
- In a mixing bowl, cream together the softened butter and icing sugar until pale and creamy (2-3 minutes).
- Add the vanilla extract, lemon juice, and lemon zest and beat until combined.
- Add the salt, then begin gradually adding the flour with the mixer on low speed. The mixture will look very dry at first, but after a minute or two it will start to come together. Keep mixing until a soft, crumbly dough forms.
- Turn the dough onto a lightly floured surface and bring it together with your hands to form a ball. Press it into a disc, then roll it out with a floured rolling pin to an even 0.6 cm (¼ in) thickness. If the dough feels soft or sticky at any point, chill it in the refrigerator for 5-10 minutes to firm up. Use a floured 5-7 cm (2-3 in) cookie cutter to cut out your desired shapes, then transfer them to a lined baking sheet and chill for 30 minutes. As the cookies chill, preheat your oven to 160℃ (140℃ fan/325℉).
- Bake for about 15-18 minutes or until lightly golden around the edges. Bake times will vary depending on the size and shape of the cookies, so watch them closely from around 10 minutes. Allow to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
- Place the white chocolate pieces in a microwave-safe bowl and heat in 30-second intervals, stirring between each, until fully melted. If the chocolate is too thick (this will depend on the brand), stir in a neutral-flavoured oil, one tsp at a time, until it reaches a dippable consistency.
- Line a baking sheet or two with parchment paper. Dip each cookie half way in the melted chocolate and allow any excess to drip off. Carefully place on the baking sheet and immediately sprinkle with chopped pistachios. Chill in the fridge until the chocolate has set.
