Ingredients and Substitutions
What you need:
unsalted butter – we’ve used both unsalted butter and salted butter interchangeably in this recipe, so I don’t believe it’s going to matter a lot.
granulated sugar – we use Dixie Crystals sugar, but you can use whatever sugar you happen to have.
eggs – for the purposes of this recipe, we used large size eggs.
all purpose flour – while I am sure there are other flours that would work just fine, we have only tested this recipe with all purpose flour.
baking powder – do not confuse baking powder and baking soda. They are definitely not the same and will do very different things in this recipe.
salt – if you use salted butter, you can eliminate this extra salt if you desire.
freshly squeezed key lime juice – we used Key Limes from Melissa’s produce, but this recipe would be just as good with regular limes.
grated key lime peel – same with the juice, regular lime juice would work just fine.
powdered sugar – if you decide not to make the icing for the top, this isn’t necessary.
milk – if you decide not to make the icing for the top, this won’t be necessary.
I listed substitutions above.
While I’m sure there are other substitutes for those ingredients listed, any major changes are going to change the original flavor and texture of the cookies.
How to Make Key Lime Sugar Cookies
There is a printable recipe below, but here is a brief summary of how to make these cookies.
Preheat your oven to 350 degrees F.
Prepare your cookie sheet.
Combine butter, sugar and eggs. Add key lime juice and grated lime peel.
In a separate bowl, whisk together the dry ingredients.
Combine all ingredients, just until combined.
For the best results refrigerate the dough for about 1 hour. If you don’t have that much time, you can freeze the dough for about 25 minutes.
This keeps the cookie dough from running or softening too quickly in the oven and becoming a large mess.
Form the dough into balls and place on your prepared cookie sheet.
Bake for 8-10 minutes.
Make up icing and spoon and spread on top.
How to Store Key Lime Sugar Cookies
The dough can definitely be made ahead. We often make it up the day before and refrigerate overnight.
For best results, form into balls, but that isn’t necessary.
Store these cookies in an airtight container for up to one week.
