My dad’s coworker made these for every office potluck

These oven baked 4-ingredient cheese puff squares are the definition of office potluck legend. My dad’s coworker used to bring a foil-lined tray of these to every work event, and people would literally hover by the table waiting for them to come out of the break room. They’re salty, cheesy, soft in the middle with crisp, golden tops, and they disappear faster than anything else on the spread. With just four basic ingredients and a simple stir-and-bake process, they’re perfect for busy weeknights, game days, or any time you need a reliable crowd-pleaser that feels nostalgic and homemade without a lot of effort.

Serve these cheese puff squares warm, right off the baking sheet, when the tops are golden and the centers are still a little soft and steamy. They pair perfectly with a simple green salad, tomato soup, or a big pot of chili if you want to turn them into more of a meal. For parties or potlucks, set them out on the foil-lined pan they baked on and add a small bowl of marinara or ranch for dipping. They’re also great alongside a veggie platter or charcuterie board—the salty cheese and buttery base balance out fresh crunchy vegetables and cured meats really well.
