Ingredients

Scale
  • 1 cup (227g) unsalted butter, browned and slightly cooled
  • 1 ½ cups (300g) granulated sugar
  • ½ cup (110g) light brown sugar
  • 2 large eggs, room temperature
  • 2 tsp vanilla extract
  • 2 ¾ cups (345g) all-purpose flour
  • 2 tsp cream of tartar
  • 1 tsp baking soda
  • ½ tsp salt
  • 2 tbsp cinnamon, divided
  • Optional: powdered sugar for dusting

Instructions

  1. Brown the butter: In a medium saucepan over medium heat, melt the unsalted butter. Stir frequently with a wooden spoon as the butter foams and then starts turning golden brown with a nutty aroma (about 5–7 minutes). Remove from heat and let cool for 5 minutes.
  2. Mix sugars and eggs: In a large bowl, combine granulated sugar and light brown sugar. Add the slightly cooled brown butter, then beat in the eggs one at a time, followed by vanilla extract. Mix until smooth and glossy (about 3 minutes).
  3. Combine dry ingredients: In a separate bowl, whisk together all-purpose flour, cream of tartar, baking soda, salt, and 1 tablespoon of cinnamon.
  4. Incorporate dry into wet: Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. Avoid overmixing.
  5. Prepare the pan: Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides.
  6. Spread the batter evenly in the prepared pan and smooth the top gently.
  7. Add cinnamon sugar topping: Mix the remaining 1 tablespoon cinnamon with 2 tablespoons granulated sugar and sprinkle evenly over the batter.
  8. Bake: Preheat oven to 350°F (175°C). Bake bars on center rack for 25–30 minutes until edges are golden and a toothpick inserted comes out with moist crumbs but no wet batter.
  9. Cool and slice: Let bars cool in the pan on a wire rack for at least 20 minutes. Lift out using parchment overhang and slice into squares or rectangles.

Notes

Use medium heat and stir constantly when browning butter to avoid burning. Avoid overmixing the batter to keep bars tender. Let bars cool completely before slicing; refrigerate for 10-15 minutes for cleaner cuts. Optional variations include gluten-free flour, adding spices like nutmeg or cardamom, chocolate chips, nuts, or dairy-free substitutions.
