These lemon meltaway cookies will melt in your mouth as you eat them. They are an easy and delicious cookie that you can make ahead of time for gifting or events.
Preheat oven to 350°F (177°C). Line a large baking sheet with parchment paper or a silicone baking mat.
In a large mixing bowl, mix together softened butter and condensed milk with a spaula until butter is completely incorporated and your mixture is smooth.
Stir in the lemon juice and zest. Add in 3/4 cup of cornstarch (reserving the last 3 tbsp). Mix in the cornstarch until a soft dough forms. If your dough is too sticky, add in 1 tbsp of cornstarch at a time, checking the dough after each addition. You want the dough to be very soft but not super sticky. To check if dough is ready, take a piece and roll between your palms. If you can form a smooth ball, then your dough is ready. If it's too sticky, add a little more cornstarch.
Scoop dough with a 1 tbsp cookie scoop and release onto prepared cookie sheet. Roll the dough between the palm of your hands until i forms a smooth ball. Place back onto prepared cookie sheet. Repeat with remaining dough, spacing cookies at least one inch apart. Press down very lightly on each dough ball with the palm of your hand, just so the surface is flat rather than round. Don't press down too much on the dough ball. Your disks should be quite thick (about 1/2 inch).
Bake cookies for about 13-15 minutes or until the cookies are puffed and edges are just starting to brown. Let cookies cool before serving. If desired, you can dust the tops with powdered sugar before serving.
Notes
Please note, these cookies are a lemon flavored version of a traditional Brazilian cookie, sequilhos also known as Brazilian cornstarch cookies. They do contain a lot of cornstarch and if you've never had sequilhos or did not grow up eating cornstarch based cookies, it may be a bit different from cookies you are used to because you will taste some of the cornstarch. The cookies are not that sweet and have a biscuit cookie-like texture. Because they use a lot of cornstarch, they do dissolve easily in your mouth which is why they are often called meltaway cookies. The texture profile may not be for everyone. I grew up eating very similar type of biscuit cookies so I enjoy these and many readers who grew up eating sequilhos love these. However, many readers who did not ever eat cornstarch based cookies before don't like that they taste like cornstarch. If you're looking for a meltaway cookie that uses regular flour and butter, we recommend you try our lemon melting moment cookies.
The butter must be completely softened before using. I usually leave mine on the counter for a few hours and let it come to room temperature. If your kitchen is particularly cold, you may need to place the butter somewhere else to warm it up.
When measuring the cornstarch, measure it like you should measure flour. Don't dip the measuring cup directly in. Instead, use a spoon to add the cornstarch to the measuring cup and the level off the top. This will prevent your cup from being overpacked.
I have only tested this recipe with full fat sweetened condensed milk. I don't know if it works with fat free condensed milk.
Don't add extra lemon juice or zest. Doing so will add too much moisture to the dough and you will have to add a lot more cornstarch to make the dough form which will result in crumbly and dry cookies.
The dough should be very soft and may even look sticky. The best way to test if it is ready is to roll a piece between your palms and see if you can form a ball. If you can, then your dough is ready.
