The Sour Cream Cookie recipe this is based off of, is probably the first cookie I REALLY remember helping to make. My favorite part was running my finger under the cooling rack and picking up all the glaze that had landed on the newspaper underneath it. Ahhh……I probably didn’t even NEED to eat a cookie by the time I was done doing that! At least now I can do that without getting a major blood sugar spike-and-crash. 🙂
This recipe was inspired by a good old classic family favorite recipe, given to my mom by one of my aunts. The original was misplaced, and we made a few variations through the years, never finding the original, stained, & much-loved index card of the original recipe. I did finally come across one that was just as good as hers, so I’ve stuck with that one…until now!
I’ve trimmified this favorite family recipe and named it in honor of my aunt, because without her, I wouldn’t have this recipe to share with you all!
It really is a family favorite, because once upon a time several years ago, I made a triple batch, I believe of these cookie (white flour & sugar filled ones!) which yielded about 12 dozen LARGE cookies….they were GONE within 2 days.
