Ingredients

Scale
  • 1 cup (2 sticks or 227g) unsalted butter, browned
  • 1 cup (200g) granulated sugar
  • 1/2 cup (packed, 100g) light brown sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 1/2 cups (180g) all-purpose flour
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/4 cup (50g) granulated sugar (for cinnamon sugar swirl)
  • 2 teaspoons ground cinnamon (freshly ground preferred)

Instructions

  1. Brown the butter: Place 1 cup (2 sticks or 227g) unsalted butter in a medium saucepan over medium heat. Stir frequently as it melts, then begins to foam and brown. Watch carefully for a nutty aroma and golden color, about 5-7 minutes. Remove from heat and pour into a mixing bowl to cool slightly (around 5 minutes).
  2. Mix sugars and eggs: To the warm brown butter, whisk in 1 cup (200g) granulated sugar and 1/2 cup (packed, 100g) light brown sugar until smooth. Add 2 large eggs (room temperature) one at a time, whisking well after each. Stir in 2 teaspoons vanilla extract. This should take about 3 minutes.
  3. Combine dry ingredients: In a separate bowl, sift together 1 1/2 cups (180g) all-purpose flour, 1 teaspoon baking powder, and 1/4 teaspoon salt.
  4. Fold dry into wet: Gradually add the dry ingredients to the wet brown butter mixture, folding gently with a spatula just until combined. Avoid overmixing to keep the blondies tender. This step should take about 2 minutes.
  5. Prepare cinnamon sugar swirl: In a small bowl, mix 1/4 cup (50g) granulated sugar and 2 teaspoons ground cinnamon until evenly combined.
  6. Assemble in pan: Pour half of the blondie batter into your parchment-lined 8×8-inch baking pan, smoothing it evenly. Sprinkle half the cinnamon sugar mixture over the batter. Add the remaining batter on top, then sprinkle the rest of the cinnamon sugar. Using a butter knife or skewer, gently swirl the cinnamon sugar through the batter to create a marbled effect without overmixing.
  7. Bake: Place in a preheated oven at 350°F (177°C) for 25-30 minutes. Start checking at 25 minutes; the blondies should be golden on top and a toothpick inserted near the center should come out with a few moist crumbs but not wet batter.
  8. Cool and serve: Allow the blondies to cool completely in the pan on a wire rack before slicing, about 30 minutes.

Notes

Watch the butter closely when browning to avoid burning. Use room temperature eggs for smooth batter. Do not overmix the batter to keep blondies tender. Swirl cinnamon sugar gently to create pretty ribbons without fully mixing. Tent with foil if edges brown too quickly. For gluten-free, substitute flour with gluten-free blend. For dairy-free, use vegan butter and flax eggs.
