- 1 teaspoon baking powder — a touch of lift for a soft bite.

Quick note: these bars are ready faster than takeout sweet treats, but the smell that fills your kitchen makes them feel like they took a labor of love.
Step-by-Step Instructions
- Preheat the oven to 350°F (175°C). Line a 9×13-inch pan with parchment or lightly grease it.
- In a large bowl, cream together the softened butter and granulated sugar until pale and fluffy — the rhythm of your mixer should be steady, and the mixture will smell buttery and sweet.
- Beat in the egg and vanilla until glossy and combined.
- In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients into the wet, mixing until a soft dough forms. It will feel tender and slightly sticky.
- Press the dough evenly into the prepared pan; the simple act of smoothing it out will be strangely satisfying. Bake for 18–22 minutes or until the edges are lightly golden and a toothpick comes out mostly clean. Your kitchen will smell amazing at this point.
- Let the bars cool completely in the pan while you make the frosting: beat the softened butter, powdered sugar, vanilla, and enough milk to reach a spreadable consistency. Taste and adjust sweetness or vanilla as desired.
- Spread the frosting over the cooled bars with a spatula and add sprinkles or a light dusting of sanding sugar for sparkle. Slice into squares and serve.
Tips and Variations
- For a festive meal, tint the frosting with gel food coloring for themed parties.
- Add lemon zest to the dough or frosting for a bright, fresh note.
- Make them into a healthier option by using applesauce for half the butter — texture will be slightly different but still delicious.
- Turn them into an indulgent dessert bar by sandwiching a layer of jam or Nutella before baking.

Serving Suggestions
Serve Sugar Cookie Bars warm with a scoop of vanilla ice cream for an indulgent dessert, or pack them in seasonal tins for gifting. They pair beautifully with a simple hot cocoa or a bright cold glass of milk. For a brunch spread, place a tray of bars alongside fruit and a coffee station to create a cozy, celebratory table. If you are serving at a savory dinner, balance the sweetness with a main like brown sugar garlic chicken for a comforting, homey menu that feels both special and familiar.
Storage and Make-Ahead Tips
- Room temperature: Keep in an airtight container for up to 3 days — the frosting will stay soft and inviting.
- Refrigerator: Store for up to 1 week if your kitchen is warm; bring to room temperature before serving for the best texture.
- Freezing: Freeze unfrosted bars for up to 3 months. Thaw, then frost before serving for the freshest result.
- Make-ahead: Bake the bars a day in advance, frost on the day you plan to serve, and sprinkle just before guests arrive.
Pro Tips from the Kitchen
- Don’t overbake — pull the bars when the center is just set; carryover heat will finish them and keep them soft.
- Use room-temperature ingredients for even mixing and a luxuriously tender crumb.
- For a perfectly smooth frosting, sift powdered sugar before mixing to avoid lumps.
- If your frosting is too stiff, add milk a teaspoon at a time until spreadable; if too thin, add more powdered sugar.
- Press the dough evenly into the pan with lightly floured fingers or the bottom of a measuring cup for flawless edges.
FAQs
Q: Can I make these gluten-free?
A: Yes — substitute a one-to-one gluten-free flour blend and add 1/4 teaspoon xanthan gum if your blend lacks it; texture may vary slightly but will still be delicious.
Q: Can I skip the frosting?
A: Absolutely. The bars are delightful plain or simply dusted with powdered sugar. Frosting elevates them to party-ready, but they are still comforting without it.
Q: How thin or thick should I slice them?
A: Aim for about 2-inch squares for a classic treat size. Thicker slices feel more cookie-like; thinner slices are perfect for nibbling.
Q: Can I use salted butter?
A: Yes — if you use salted butter, reduce added salt in the dough by half to keep the balance right.
