These sugar cookie bars are soft, flavorful, and slightly chewy. They’re delightful to make, decorate, and enjoy.

Why it works
These bars have a tender, soft crumb with a pleasant chew and bursts of color from sprinkles in both the cookie and the frosting. A small amount of cornstarch keeps the dough light, puffy, and tender—it’s a simple trick I use in many soft cookie recipes. The cornstarch helps control structure without weighing the bars down.
Cream cheese contributes tang, richness, and moisture while helping maintain that soft, slightly chewy texture. Using cream cheese in both the dough and the frosting elevates the flavor and mouthfeel.
Another advantage is that the dough does not require chilling before baking. Because you press the dough into the pan, spread isn’t a concern. If you prefer to bake later, you can chill or freeze the dough—see the storage section for details on saving the dough for later use.

Ingredients
This recipe uses common pantry staples—most of these you likely already have on hand.
- Flour — All-purpose or white whole wheat flour works fine. Bleached or unbleached is okay.
- Cornstarch — Adds tenderness and helps the bars stay light and puffy. Arrowroot can be used as a substitute.
- Sugar — Granulated sugar is used in the cookie; powdered sugar is used for the frosting. I don’t recommend brown sugar or substitutes for this recipe.
- Butter — Unsalted butter provides richness and flavor. Avoid margarine for best results.
- Cream cheese — Adds moisture, tang, and a soft texture. Use full-fat block cream cheese for best results.
- Eggs — Provide structure, moisture, and chew.
- Leavening — A small amount of baking powder helps prevent a dense texture.
- Vanilla — Pure vanilla extract is the primary flavor in both cookie and frosting.
- Salt — Salt enhances flavor and balances sweetness; fine sea salt is recommended.
And of course, sprinkles—add as many as you like. (The original recipe author notes a homemade sprinkle recipe is available elsewhere.)

Tips
Use real unsalted butter, softened to room temperature; margarine generally won’t produce the same texture or flavor. Use full-fat block cream cheese—lower-fat versions contain more water and can make the dough or frosting runny.
FAQs
Yes. Add about two tablespoons of lemon zest when creaming the butter and sugar, and add about one tablespoon of lemon juice when beating in the eggs. The bars can also serve as a thick cookie base for lemon bars.
Yes. Bake the batter in two 9×13 pans or on a half-sheet pan; a larger pan will reduce baking time, so watch closely.

Storage
This recipe stores very well. Chilling the dough can deepen the flavor if you want to bake later. Unbaked dough can be refrigerated up to three days or frozen for up to a month—wrap tightly in plastic wrap and place in an airtight container.
Once baked and cooled, bars can be kept at room temperature in an airtight container for up to a week when frosted. Refrigerating cut bars is not recommended because it dries them out; instead, freeze cut bars if you plan to store them longer. For freezing, place cut bars on a baking tray to freeze solid, then transfer to an airtight container or freezer bag. Thaw at room temperature in a single layer.
