Step by Step Instructions
Step 1: Preheat your oven to 350°F (177°C). Line a 9×9-inch square baking pan with parchment paper and lightly grease it.
In a large bowl, whisk together the room-temperature butter and granulated sugar until creamy and smooth (about 3 minutes). Add the eggs and vanilla extract, whisking until the mixture is pale, thick, and fully combined.
Step 2: In a separate bowl, whisk together the flour, cream of tartar, baking soda, cinnamon, and salt until evenly mixed. This ensures the leavening and spice are distributed throughout the dough.
Step 3: Gradually add the dry ingredients to the wet ingredients, mixing on low or by hand until a thick, soft dough forms — don’t overmix.
Transfer the dough to the prepared pan and press it evenly into the corners using a spatula or your fingertips to create a smooth, level surface.
Step 4: In a small bowl, combine the granulated sugar and ground cinnamon for the topping. Sprinkle evenly over the dough from about 8–12 inches above for even coverage.
Bake for 23–25 minutes, or until the edges are set and the center still looks slightly soft.
Let the bars cool completely in the pan, then lift out using parchment and slice into squares.
Expert Tips
- Slightly underbake for chewiness: The center should look soft when you pull them from the oven.
- Room temperature ingredients: Butter and eggs mix more evenly, giving you that perfect texture.
- Measure flour correctly: Spoon and level (or weigh) for accuracy — too much flour makes bars dry.
- Even sugar crust: Sprinkle the topping from a height for that signature crackly look.
- Cool before cutting: This helps the bars set cleanly for beautiful slices.
