This nostalgic easy lemon cake—whether made from a boxed mix or from scratch—is bright, comforting, and easy to love. Get tips on ingredients, storage, make-ahead instructions, and fun add-ins to make it your own.

When I was little, my mom always baked stuff for us and the house always smelled great when we came home from school. She was constantly trying new recipes. A lot of times, she would whip up an old favourite – something that my grandmother may have taught her from back home. But, oftentimes, she would try something new that she would find in a magazine or from another mom on the street. There was a cake that she made (that almost every housewife made back in the day) which was made from a boxed cake mix and soaked in rum…like, SOAKED! So, we weren’t allowed to eat that (but I did manage to sneak a few bites in here or there). Once she realized we loved it so much but couldn’t enjoy it like all the adults, she did a deep dive into her magazine subscription and found this beauty! This easy lemon cake starts with …wait for it…a boxed cake mix!! It’s a really delicious cake and a great recipe to have in your back pocket for those days that your best friend says, “Hey, I’m coming by for a coffee…should I pick up a cake?” And you will happily say, “Nahhh, I’ll just whip up a lemony treat!!”
