25 Vintage Bar and Square Desserts

If you grew up in the 70s or 80s like I did, you probably remember potluck dessert tables lined with pans of bars and squares. No fancy decorating, no fussy layers—just simple, comforting sweets baked in 9x13 pans, cut into squares, and shared with love. My grandma always had a pan cooling on the counter, whether it was gooey lemon bars dusted with powdered sugar or rich brownies tucked into a tin for church socials.

These 25 vintage bar and square desserts are straight from those memories. Some were Depression-era staples, some came out of mid-century recipe contests, and many became holiday traditions we still bake today.
