Ingredients and Variations
For the thumbprint cookies, you will need:

Egg yolk - Use room temperature eggs.
Vanilla extract - Optional, but a great flavor enhancer.
Salt - To balance the sweetness.
Flour - All purpose flour works best for these cookies. Make sure to weigh your flour using digital kitchen scales for accuracy. Use room-temperature flour.
For the homemade lemon curd, you will need:
Lemon Zest + Juice.
Sugar - Granulated or caster.
Eggs - You will need one egg and one egg yolk for the small batch lemon curd.
Butter - Use unsalted butter (cubed).
How to Make Thumbprint Cookies
Preheat the oven to 350°F (177°C) and line 2 large baking sheets with parchment paper.
Cream together the softened butter and sugar (using a stand or handheld electric mixer) until pale and fluffy.
Add egg yolks, vanilla extract, and a pinch of salt and mix well. Scrape any ingredients from the sides of the bowl.
Finally, add the flour. Note: the mixture might be a little crumbly at first, but the dough will come together as you keep mixing it.
Use a cookie scoop (or one tablespoon) to measure the cookie dough.
Roll into dough balls and roll each ball into granulated sugar, then transfer to prepared cookie sheet, leaving a 2-inch space between each one.
Using your thumb or the back of a rounded measuring spoon, press an indentation into the center of each cookie dough ball.
Repeat these steps for the remaining cookie dough.
Bake cookies in a preheated oven for 11-13 minutes or until set and the bottoms are lightly browned.
Remove from the oven. At this point, you can repeat the indentation step (pressing very lightly) if the dough has risen slightly and the previous indentation is gone. Be careful as the cookies will be hot!
Cool the cookies on the baking sheet for 10 minutes, then carefully transfer the cookies to a wire rack to cool completely.
Make sure the cookies have cooled down completely before filling with lemon curd.
How to Make Homemade Lemon Curd
This easy lemon curd recipe yields a small batch of lemon curd filling, enough to fill 18-22 thumbprint cookies.
Feel free to double or triple the amounts for a larger batch or storing.
Beat together the egg, egg yolk, sugar, lemon zest, and lemon juice in a medium bowl.
Transfer the mixture to a small saucepan and stir over medium-low heat until the sugar dissolves.
Add cubed cold butter gradually and stir after each addition until butter is melted.
Do not let the lemon curd bubble or boil at any point!
Continue cooking the mixture for a few minutes. Use a wooden spoon to stir the mixture frequently.
Lemon curd is ready once the mixture has thickened and coats the back of the wooden spoon or when it leaves a coating on the side of the saucepan when tilting it.
Once ready, pour the mixture through a fine-mesh strainer into a glass bowl to remove any bits of lemon zest.
Allow the mixture to cool for 15-20 minutes before filling the cookies. Lemon curd will continue to harden as it cools.
Transfer 1-1½ teaspoons of cooled lemon curd into each indentation of your thumbprint cookies. Dust with powdered or icing sugar as desired. Then leave to set for around 15 minutes, then serve and enjoy!

This applies for flour, butter, and sugar.
Digital scales are more accurate than cups as ingredients are measured by their actual weight.

Remember though, that lemon curd will continue to thicken as it cools down.
