Ingredients
Before you start to make this lemon coolers recipe, measure and prepare your ingredients so the cooking process will go smoothly and easily.
Butter- use unsalted butter for this recipe. Only butter will work for this recipe, no margarine, and no coconut oil. Margarine has a weird taste and can ruin the flavor of these delicious cookies.
Egg yolk- you will need 1 egg yolk for this recipe. Make sure that your egg yolk is at room temperature.
Lemon juice- use fresh lemon juice for this recipe. Fresh lemon will give you the best result. We don't recommend using store-bought lemon juice. This will make the flavor pop!
Lemon zest- you will need ½ teaspoon of lemon zest. We recommend zesting the lemon first and then juicing it.
Flour– we used all-purpose flour for this recipe. cake flour will work great as well.
Cornstarch-Â cornstarch helps to create a tender texture for these cookies, plus, it keeps the cookie thick and soft.
Baking powder– baking powder allows the cookies to spread. Make sure that your baking powder is not expired.
Granulated sugar– we like to use granulated sugar, also the most common sugar used in baking. Caster sugar will work great as well.
Vanilla extract- adds extra flavor.
Lemon extract- for extra lemony flavor. This is optional.
Kosher salt- you will need about ¼ teaspoon of kosher salt for this recipe.
Powder sugar(for assembly)- you will need powder sugar for this recipe. you don’t have to buy powdered sugar, you can simply make it at home by blending granulated sugar in a blender or food processor.
Instructions
Into a medium mixing bowl, add the room temperature butter, lemon zest, granulated sugar, kosher salt, and vanilla extract, and cream it with an electric hand mixer until creamy and smooth.
Add the egg yolk, and fresh lemon juice, and mix well until combined.
Into a medium mixing bowl, add the flour, cornstarch, and baking powder, and mix with a whisk until combined.
Add the flour to the butter mixture and mix with a spatula until just combined and there are no flour pockets visible.
Cover the bowl with a plastic wrap tightly and let it chill in the fridge for at least 1 hour.
Scoop out about 1 tablespoon of the batter and shape it into a ball. We used a small cookie scoop to scoop out the cookies, this way they are even in size and will bake evenly.
Place the cookie dough balls on a parchment paper-lined baking sheet, flatten them out a little bit with the palm of your hand, and bake in a 180c (350f) preheated oven for 9-11 minutes.
Let the cookies cool until they are safe to touch. Fill a medium mixing bowl with powdered sugar and roll each cookie in the powdered sugar. Serve and Enjoy!
Expert Tips
- Use room temperature ingredients. It is important that you use room-temperature ingredients like eggs and butter. This step ensures that your mixture mixes into a homogenous mixture and bakes perfectly.
- Don’t overmix the batter, you don’t want to develop the gluten in the flour. This step ensures you have moist cookies and not dense and dry cookies.
- Make sure that your butter is at room temperature. An hour or two before making these cookies, take the butter out of the fridge and let it come to room temperature. The butter should be soft to the touch. If your butter is too cold, it will be harder to mix and there will be lumps of butter in the dough.
- Measure your flour correctly! When measuring your flour, avoid scooping it with a measuring cup. Instead, stir the flour with a spoon to create as many air pockets as possible, and spoon it into your measuring cup. Finally, level it with a back of a knife.
- Line your sheet pan with parchment paper or a silicone mat! This step helps the cookies to bake evenly, and it makes sure that your cookies release easily from the pan.
- Before you start to make this recipe, measure and prepare your ingredients so the cooking process will go smoothly and easily.

Hi,
Do the cookies store well at room temperature or should they be refrigerated? Also, are the cookies sturdy enough for to be mailed if packed securely in a box?
