Buttermilk Sugar Cookies
Making great sugar cookies begins with a great recipe and this one is absolutely fantastic. This soft buttermilk sugar cookie is a recipe I recently found on the back of the sugar package that looked interesting. Yes, I look at the recipes on the back of the sugar package, don’t you?!
I did however, make some small changes and honestly, these are easily one of the best sugar cookies I have ever had! They are soft and pillow-like and they have amazing flavor. I have brought these to several family gatherings now and they disappear so fast. Even my son who does not like cookies raves about them, they are that good! Give them a try, you will love them too!

Is there a substitute for buttermilk?
Here are several ideas for substitutes to buttermilk in this recipe. You can instead use plain yogurt, greek yogurt or sour cream instead. First measure out 3/4 cup, then add 3 TBSP of milk and whisk to combine.
How to make buttermilk at home
You can make buttermilk at home by combining milk with either plain white vinegar or lemon juice. First measure out 1 TBSP of either vinegar or lemon juice into a 1 cup measuring cup. Then add enough milk to yield 1 cup. Stir and let mixture sit for 10 minutes, then proceed with your recipe.
Can you freeze buttermilk sugar cookies?
Yes you can either freeze the sugar cookie dough prior to baking or you can bake the cookies, then freeze them to frost and eat later on. I like to scoop the dough into balls and line a cookie sheet with them, then placing the entire sheet in the freezer. Once frozen, remove the dough balls and place in an airtight container. Freeze up to 2 months. Before baking, place dough on cookie sheets and let sit 15 minutes to thaw. Bake as directed.
How long should I let these cookies cool?
Cookies are best left to cool on the baking sheet they’re cooked on for 3-4 minutes, then you can transfer them to a cooling rack to cool further. This way, they don’t fall apart as cookies are pretty soft still when they’re pulled out of the oven. After a couple minutes on a cooling rack, cooking are usually cool enough to eat! Warm cookies are the best!
Buttermilk Sugar Cookies are a cookie lovers’ dream come true! This sugar cookie with buttermilk is seriously so soft and delicious.

My grandmother made this for her xmas cookies every year. When I was old enough, she taught me and we’ve had it always. It was a tradition passed down in our family to every generation. I am now the family matriarch. My mother passed 1and1/2 years ago at 95 yrs old. Our lineage was southern from North Carolina. My oldest daughter is the one who makes them (hundreds) every xmas and sends them all over the country. I am now almost 76 and my son’s daughter and I w/ her Mom are starting the latest version here in Ohio. We’ve decided to have a competition with the N C. Family this year… It’s a wonderful memory AND tast tradition to carry on in your family. ONLY CHRISTMAS COOKIE I’LL EAT! LOVE THEM.🥰
