There’s something about the tangy sweetness of key lime cookies that transports me back to my childhood kitchen in Chicago, where my babcia would whip up the most delightful treats. Growing up with a Polish-American family, our kitchen was always filled with the comforting aroma of freshly baked goods, and while key lime cookies aren’t exactly a traditional Polish dessert, they’ve become a beloved favorite in our household. These cookies are a perfect blend of tart and sweet, with a buttery texture that melts in your mouth. They remind me of the times my kids, Ella and Peter, would sneak into the kitchen, hoping to nab a cookie or two before dinner. Today, I’m excited to share this recipe with you, hoping it brings a touch of joy and nostalgia to your home as it does to mine.
