Description

Discover the key differences between chewy blondies and marbled brookies, plus how to bake each at home! This guide offers step-by-step instructions, ingredient tips, and expert tricks for dessert bars everyone will love.


Ingredients

Scale
  • 1 cup (225g) unsalted butter, melted
  • 1 ½ cups (300g) brown sugar, packed
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 2 cups (250g) all-purpose flour
  • 1 teaspoon baking powder
  • ¼ teaspoon salt
  • 1 cup (175g) chocolate chips (optional)
  • 1 cup (150g) chopped nuts (optional)
  • For Brookies (if making the hybrid):
    (Prepare a basic brownie batter and classic chocolate chip cookie dough. Can use your favorite recipes for each, or use ready mixes for speed!)

Instructions

  1. Preheat oven to 350°F (175°C). Grease and line an 8×8-inch (20×20 cm) baking pan with parchment paper for easy removal.
  2. In a large bowl, whisk melted butter and brown sugar until smooth and creamy.
  3. Beat in eggs and vanilla extract until fully combined.
  4. In a separate bowl, mix flour, baking powder, and salt. Gradually add to wet mixture, stirring until just combined.
  5. Fold in chocolate chips and/or nuts if using.
  6. Pour batter into prepared pan and spread evenly.
  7. Bake for 25–30 minutes, or until golden brown and a toothpick comes out mostly clean.
  8. Let cool in pan for 10 minutes, then transfer to a wire rack. Cut into squares and enjoy!

For Brookies:

  1. Prepare brownie batter and chocolate chip cookie dough separately.
  2. Spread brownie batter in a lined 8×8-inch pan.
  3. Drop spoonfuls of cookie dough on top, swirl lightly with a knife for a marbled effect.
  4. Bake at 350°F (175°C) for 30–35 minutes. Cool, slice, and enjoy!

Notes

  • Underbake by 1–2 minutes for extra gooey centers.
  • Add flaky sea salt on top before baking for a flavor boost.
  • Both bars freeze well—wrap tightly and store for up to 3 months.
  • For gluten-free or vegan options, substitute flour and use plant-based replacements for eggs and butter.
