Key Ingredients
These brown sugar cinnamon bars are made with classic baking staples. The full measurements are included in the recipe card below, but here is a helpful look at the most important ingredients and why they matter.

Variations

How to Make Brown Sugar Cinnamon Bars
This is a quick overview of the process. The complete step-by-step instructions are included in the recipe card below.

- Beat the butter until light and fluffy. Add the vanilla extract, powdered sugar, and egg, then mix in the flour and salt until a soft dough forms.

- Stir together the brown sugar cinnamon filling until evenly combined.

- Press half of the dough into a parchment-lined 8×8-inch baking dish, then spread the cinnamon filling over the base.

- Add the remaining dough on top and gently press it into an even layer. Bake until the center is set and a toothpick comes out clean or with a few crumbs.

- Allow the bars to cool in the pan while you prepare the cinnamon icing.

- Spread the icing over the cooled bars. Let it set slightly, then lift the dessert from the pan and slice into bars.
Expert Tips
- Use room temperature butter so the dough mixes smoothly and evenly.
- Do not overmix the dough after adding the flour. Overmixing can make the bars less tender.
- If the dough feels sticky, lightly oil your hands or use the bottom of a greased measuring cup to press it into the pan.
- Let the bars cool before adding icing so the topping does not melt completely into the dessert.
- For a slightly gooier texture, serve the bars while the icing is just barely set.
- Use parchment paper with overhang to make lifting and slicing the bars easier.
