Southern 3-ingredient creamy cheddar squares are the kind of easy, crowd-pleasing bake that earns a permanent spot in the game-day and potluck rotation. Built from just a few pantry and refrigerator staples, they come together with very little effort and bake into rich, cheesy squares with a soft center and crisp golden edges, much like the simple, practical casseroles and snack bakes long favored across Southern kitchens.
Serve these warm as an appetizer with pickle spears, hot sauce, or a little ranch on the side, or add them to a tailgate spread with sausage balls, deviled eggs, and a bowl of chili. They also work well alongside tomato soup, a crisp green salad, or fresh fruit if you want to turn them into a simple lunch or casual supper.
Southern 3-Ingredient Creamy Cheddar Squares
Servings: 12 squares
Ingredients
2 cups baking mix
2 cups shredded sharp cheddar cheese
1 cup mayonnaise
Directions
1. Preheat the oven to 350°F and line an 8-inch square baking pan or small rimmed tray with foil, then lightly grease the foil so the squares release easily after baking.
2. In a medium bowl, stir together the baking mix, shredded cheddar cheese, and mayonnaise until a thick, evenly combined batter forms.
3. Spread the mixture evenly into the prepared pan, pressing it gently into the corners so it bakes in a uniform layer.
4. Bake for 20 to 25 minutes, or until the top is deep golden brown around the edges and the center is set with bubbling cheese on top.
5. Let the pan cool for 10 minutes, then lift out the slab using the foil, cut into 12 squares, and serve warm.
Variations & Tips
Sharper Cheese Flavor: Use extra-sharp cheddar for a more pronounced bite. Since there are only three ingredients, the cheese quality really comes through, so a good block of cheddar shredded at home will usually give the best melt and flavor.
Pan and Cutting Tip: For cleaner squares, let the bake rest long enough to firm slightly before slicing. A parchment layer over the foil can also help if you want especially tidy edges for a party tray.
Add-In Option: If you do not mind moving beyond the classic 3-ingredient version, a pinch of cayenne, a spoonful of chopped pimientos, or a little sliced green onion can add Southern character without changing the easy method.
Make-Ahead Tip: These reheat well in a low oven, which makes them practical for tailgates and potlucks. Avoid microwaving for too long, though, because it can soften the crisp edges that make the squares so appealing.
