Ingredients

Scale

  • 1/2 cup granulated sugar
  • 2 cups all-purpose flour
  • 1 cup brown sugar
  • 3 large eggs
  • 1/2 cup corn syrup or maple syrup
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 1/2 cup chopped pecans or walnuts (optional)

  2. Cream 1/2 cup butter with granulated sugar until light and smooth.
  3. Mix in flour until a soft dough forms.
  4. Press dough evenly into the prepared pan.
  5. Bake crust for 12–15 minutes until lightly set.

  7. Add eggs one at a time, mixing gently.
  8. Stir in corn syrup, vanilla, and salt.

  • Let squares cool fully before cutting for clean slices.
  • Maple syrup adds deeper flavor if substituted for corn syrup.
  • Store layered with parchment paper to prevent sticking.
