Sugar Cookie Bars Recipe
Introduction
Sugar cookie bars are a delightful twist on the classic cookie, offering a soft, chewy texture that’s perfect for sharing. Topped with creamy buttercream frosting and optional sprinkles, they make a festive treat for any occasion.

Ingredients
- 2 3/4 cups (358g) all-purpose flour (measured properly)
- 1/2 tsp baking soda
- 1/2 tsp salt
- 1 cup plus 2 tbsp (252g) unsalted butter, room temperature
- 1 cup (207g) granulated sugar
- 2 tbsp (28g) light brown sugar
- 1 large egg, room temperature
- 2 tsp vanilla extract
- 1/2 cup (112g) unsalted butter, room temperature (for frosting)
- 2 cups (230g) powdered sugar
- 1/2 tsp vanilla extract (for frosting)
- 1–2 tbsp cream or water
- Gel icing color, optional
- Sprinkles, optional
Instructions
- Step 1: Preheat the oven to 350°F (180°C). Prepare a 9×9-inch square baking pan by spraying it with non-stick baking spray or lining it with parchment paper, leaving some overhang for easy removal.
- Step 2: In a medium bowl, combine the flour, baking soda, and salt. Set aside.
- Step 3: In a large mixing bowl, cream the butter, granulated sugar, and brown sugar together on medium speed until the mixture is light in color and fluffy, about 2-3 minutes.
- Step 4: Add the egg and vanilla extract to the butter mixture and mix until fully combined.
- Step 5: Gradually add the dry ingredients to the wet mixture and mix just until combined. Avoid overmixing. Use a rubber spatula to bring the dough together into a cohesive ball.
- Step 6: Press the dough evenly into the prepared baking pan. Bake for 17-23 minutes, or until the edges are lightly golden.
- Step 7: Let the cookie base cool completely in the pan for 2-3 hours to firm up.
- Step 8: For the buttercream frosting, beat the butter in a mixing bowl until smooth. Add the powdered sugar and mix until combined. Stir in the vanilla extract and 1 tablespoon of cream or water. Add more cream or water if needed to reach desired consistency.
- Step 9: If desired, tint the buttercream with gel icing color.
- Step 10: Spread the frosting evenly over the cooled cookie base. Sprinkle with decorations if using.
- Step 11: Use the parchment paper overhang to lift the cookie bars from the pan. Cut into squares and serve.
Tips & Variations
- For a lemon twist, add 1 tsp lemon zest to the dough and vanilla-free buttercream.
- Use a silicone spatula to press the dough evenly for a perfectly flat cookie base.
- Add chopped nuts or chocolate chips to the dough for extra texture.
- Store frosting separately if you want to assemble the bars later to keep texture fresh.
Storage
Store the sugar cookie bars in an airtight container at room temperature for up to 4-5 days. If refrigerated, allow them to come to room temperature before serving for the best texture. Reheat briefly in a low oven or microwave if you prefer them warm.

FAQs
Can I use salted butter instead of unsalted butter?
Yes, but reduce or omit additional salt in the recipe to avoid a salty taste.
How do I prevent the cookie bars from becoming too hard?
Be sure not to overbake them and allow them to cool completely before frosting. The bars will firm as they cool but remain soft and chewy inside.
