Make-Ahead, Storage & Reheating
Make-Ahead: You can assemble the dough, press it into the pan, and refrigerate it (covered) for up to 24 hours before baking. Brush with butter just before sliding into the oven, and add a few extra minutes to the bake time to account for the chilled dough.
Storing Leftovers: Keep cooled squares in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. Place a paper towel in the container to absorb any excess moisture.
Reheating: For the best texture, reheat squares in a 350°F oven or toaster oven for 5–7 minutes, or in an air fryer for 3–4 minutes, until warmed through and slightly crisp on the outside. The microwave works in a pinch but will soften them.
Freezing: These squares freeze beautifully. Arrange cooled squares on a baking sheet and freeze until solid, then transfer to a freezer-safe bag. They’ll keep for up to 3 months. Reheat directly from frozen in a 350°F oven for 10–12 minutes.
Frequently Asked Questions
Can I make this recipe with all-purpose flour instead of self-rising?
Yes. For each cup of all-purpose flour, whisk in 1½ teaspoons of baking powder and ¼ teaspoon of fine salt. For this recipe, that’s 3 teaspoons baking powder and ½ teaspoon salt total.
What if I don’t have Greek yogurt or sour cream?
Plain regular yogurt (not Greek) can work, but it’s thinner and may require a couple of extra tablespoons of flour to achieve the right dough consistency. You can also use a thick, plain plant-based yogurt for a dairy-free version along with dairy-free cheese and butter.
Can I use a different cheese?
Absolutely. Sharp cheddar is classic, but a Mexican blend, Colby Jack, Gruyère, or even smoked Gouda are all delicious. Avoid very soft cheeses like fresh mozzarella, which release a lot of water.
My dough is too sticky to handle. What should I do?
Lightly flour your hands or the back of the spatula you’re using to press it into the pan. A little extra flour on the surface won’t hurt. Sticky dough often yields the softest biscuits.
Why didn’t my squares rise much?
Self-rising flour loses its leavening power over time. If your flour is old, the baking powder may be expired. Also, overmixing can deflate the dough. Make sure your oven is fully preheated to 400°F before baking.

Ingredients
- 2 cups self-rising flour
- 1½ cups shredded sharp cheddar cheese
- 1½ cups Greek yogurt or sour cream
- ¼ cup melted butter, for brushing
Optional Flavor Boosters:
- ½ teaspoon garlic powder
- 1 tablespoon chopped fresh parsley or 1 teaspoon dried herbs

Instructions

- Mix dry ingredients and cheese. In a large bowl, stir together the self-rising flour and shredded cheddar until the cheese is coated.
- Add yogurt or sour cream. Add the Greek yogurt or sour cream and stir just until a thick, soft dough forms. Do not overmix.

- Cool and cut. Let rest in the pan for 5 minutes, then lift out using the foil or parchment and cut into squares. Serve warm.
Notes
- For homemade self-rising flour: whisk together 2 cups all-purpose flour, 3 teaspoons baking powder, and ½ teaspoon salt.
