Classic Sugar Cookies Recipe for a 9x9 Pan

Classic sugar cookies baked in a 9×9 pan are perfect for a quick, sweet treat or a fun baking project. Their soft, buttery texture and just-right sweetness make them a versatile choice for any occasion, from casual snacking to festive gatherings. This recipe yields a deliciously tender cookie bar that’s easy to prepare and customizable with your favorite toppings or decorations.

Ingredients

1 cup (227 grams) unsalted butter, softened
1 1/2 cups (300 grams) granulated sugar
2 large eggs
1 teaspoon vanilla extract
2 1/2 cups (310 grams) all-purpose flour
1 teaspoon baking powder
1/2 teaspoon salt

Instructions

Preheat your oven to 350°F (175°C). Grease or line a 9×9-inch square baking pan with parchment paper for easy removal.
In a large mixing bowl, beat the softened butter and sugar together using an electric mixer on medium speed until the mixture is light and fluffy, about 2-3 minutes.

Add the eggs one at a time, beating well after each addition to ensure they are fully incorporated. Mix in the vanilla extract.
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Do not overmix, as this can make the cookies tough.
Pour the batter into the prepared pan, spreading it evenly with a spatula or the back of a spoon to ensure a uniform thickness.

Bake in the preheated oven for 25-30 minutes or until the edges are golden brown and a toothpick inserted into the center comes out clean.
Remove from the oven and let the cookies cool in the pan for about 10 minutes. Then, transfer to a wire rack to cool completely before cutting into squares.
Once cooled, cut into 9 evenly sized squares. Serve as is or decorate with icing, sprinkles, or other toppings as desired.

Tips

For softer cookies, do not overmix the batter; mix just until ingredients are combined.
If you prefer a more buttery flavor, increase the butter to 1 1/4 cups but keep the flour ratio the same.
Store the cookies in an airtight container at room temperature for up to 3 days, or freeze for longer storage.

To prevent the cookies from spreading too much, ensure the butter is softened but not melted, and do not overmix the dough.

Serving Suggestions

Serve these sugar cookie bars plain for a classic treat, or add a dusting of powdered sugar, drizzle with melted chocolate, or top with colorful sprinkles for a festive touch. They pair beautifully with a glass of milk, a cup of tea, or coffee, making them perfect for casual gatherings or afternoon snacks.

Variations

Want to customize your sugar cookies? Try these ideas:

Lemon Sugar Cookies: Add 1 tablespoon of lemon zest and 1 tablespoon of lemon juice to the batter for a citrus twist.

Cinnamon Sugar Bars: Mix 1 teaspoon ground cinnamon into the dry ingredients, and sprinkle cinnamon sugar on top before baking.
Almond Flavor: Substitute vanilla extract with almond extract for a nutty aroma.
Decorated Cookies: Once cooled, decorate with royal icing, colored frosting, or edible glitter for special occasions.

Storage and Reheating

Store the sugar cookie bars in an airtight container at room temperature for up to 3 days for optimal freshness. If you need to keep them longer, wrap tightly in plastic wrap and refrigerate for up to a week or freeze for up to 3 months. To reheat, warm individual servings in the microwave for 10-15 seconds or until soft and warm. For best texture, enjoy the cookies at room temperature or slightly warmed.

Frequently Asked Questions

Can I make these cookies gluten-free?

Yes, substitute the all-purpose flour with a gluten-free baking flour blend that measures cup-for-cup the same as regular flour. Be sure to check that your baking powder is gluten-free if necessary.

Can I double this recipe for a larger batch?

Absolutely. Doubling the ingredients will work well, but ensure you use a larger pan, such as a 9×13-inch, and adjust baking time to around 30-35 minutes, checking for doneness.

What if my cookies turn out too dry?

This can happen if overbaked or if the dough was too dry. To prevent this, measure ingredients carefully, avoid overmixing, and bake just until edges are golden. Adding a touch more butter or a tablespoon of milk to the batter can also improve moisture.

Can I add chocolate chips or nuts?

Yes, fold in 1 cup of chocolate chips or chopped nuts into the batter before baking for added flavor and texture. Reduce the flour slightly if adding a large amount of mix-ins to maintain proper batter consistency.

Is it necessary to chill the dough?

For this particular recipe, chilling isn’t required. However, if you prefer thicker bars or want to prevent spreading, chilling the batter for 30 minutes in the refrigerator can help.

How thin should the batter be spread in the pan?

The batter should be spread evenly to about 1/2 to 3/4 inch thick. Use a spatula to smooth the surface for uniform baking and consistent thickness across the bars.
