Best Blueberry Lemonade Cupcakes

Last summer, I was hunting for an easy bake to celebrate my daughter’s last day of middle school. A mom in a Facebook baking group shared a photo of cupcakes dotted with blueberries, crowned by swirls of pale-yellow frosting and topped with zesty lemon zest. The caption said, “Best end-of-year treat ever.”

I laughed—how could something so pretty taste good? But when I dug in that afternoon, the cake was tender, bright with citrus, and bursting with blueberries in every bite.

I adapted the recipe using what I had at home, just butter, plenty of lemon, a handful of fresh blueberries from the farmers’ stand, and lemonade concentrate later on as frosting. My extroverted self brought them to the neighborhood potluck, and they disappeared faster than any chocolate cake I’d ever made.

At home, my husband declared it the perfect spring bake, and my youngest daughter asked if I could make them for every celebration. Now I whip up these cupcakes anytime we need a simple, joyful dessert that feels fresh, fun, and totally family-approved.
