Ingredients
For the Homemade Lemon Curd
- 4 large egg yolks
- ¾ cup granulated sugar
- ½ cup fresh lemon juice
- 1 tablespoon lemon zest
- 6 tablespoons unsalted butter, cut into cubes

For the Shortbread Cookies
- 1 cup unsalted butter, softened
- ½ cup powdered sugar
- 2 cups all-purpose flour
- ¼ teaspoon salt
- 1 teaspoon vanilla extract
How to Make Homemade Lemon Curd
1. Separate the Egg Yolks
Carefully separate the egg yolks from the whites. The yolks create the rich, creamy texture that makes homemade lemon curd so luxurious.
2. Combine the Ingredients
In a heatproof bowl, whisk together:
- Egg yolks
- Sugar
- Fresh lemon juice
- Lemon zest
- Pinch of salt
Whisk until everything is well combined.
3. Cook Using a Double Boiler
Place the bowl over a saucepan filled with gently simmering water. The bowl should not touch the water.
Cook while whisking continuously for about 10–15 minutes.
Using a double boiler keeps the eggs from scrambling and creates an exceptionally smooth curd.
4. Watch for the Perfect Thickness
Your lemon curd is ready when it coats the back of a spoon and leaves a clean line when you run your finger through it.
Patience is key during this step.
5. Finish with Butter
Remove from the heat and stir in the butter one cube at a time.
The butter melts into the curd, giving it a glossy finish and rich, silky texture.
Allow the curd to cool completely before using.
How to Make the Shortbread Cookies
- Cream the butter and powdered sugar until light and fluffy.
- Mix in the vanilla.
- Add the flour and salt until a soft dough forms.
- Wrap and chill the dough for 30 minutes.
- Roll the dough to about ¼-inch thickness.
If you don’t have a cookie cutter, simply use a drinking glass or jar lid to cut perfectly round cookies—a simple kitchen hack that works beautifully.
Bake at 325°F (163°C) for 12–15 minutes, or until the edges are just beginning to turn golden.
Cool completely before assembling.
Assemble the Cookies
Spread a generous spoonful of cooled lemon curd onto one shortbread cookie.
Top with another cookie and gently press together.
For an elegant finish, dust with powdered sugar just before serving.
Tips for Perfect Lemon Curd Every Time
- Always use freshly squeezed lemon juice for the brightest flavor.
- Don’t skip the lemon zest—it adds incredible citrus aroma.
- Whisk constantly while cooking to prevent lumps.
- Cook gently over a double boiler instead of direct heat.
- Stir in the butter after removing from the heat for a silky finish.
- Chill the curd before filling the cookies.
Storing Your Lemon Curd

The baked shortbread cookies can be stored in an airtight container for 5 days.
Once assembled, refrigerate the cookies and enjoy them within 2–3 days for the best texture.
Frequently Asked Questions

Why use a double boiler?
A double boiler provides gentle, even heat that prevents the eggs from scrambling while producing an incredibly smooth curd.
Can I freeze lemon curd?
Yes. Freeze it in an airtight container for up to 3 months. Thaw overnight in the refrigerator before using.
