What are Blondie Bars (Brownies)

Blondies are a twist on classic chocolate brownies. They have a golden color with a deep vanilla and caramel flavor and a dense, chewy texture. Instead of cocoa, chocolate chips are stirred into the batter for pockets of melty chocolate.

Think of blondies as cookie bars—familiar, comforting, and universally loved. They’re easy to adapt and always a crowd-pleaser.

Reasons to Love Them

This is a small-batch blondie recipe made for an 8″ x 8″ pan. You can double the ingredients and bake in a 9″ x 13″ pan if you need more. A smaller batch is perfect for home because they disappear fast.

Kids enjoy helping with this recipe since it requires no electric mixer—just a bowl, a whisk, and some measuring. Remember to supervise children whenever an oven or stove is in use.

Serve warm with a scoop of vanilla ice cream or a drizzle of caramel for an extra-special treat.

Ingredients You’ll Need

Here’s what you’ll need to make classic blondie bars:

Ingredients measured out in individual containers.

Butter — use real butter for best texture and flavor.

Light brown sugar — light is preferred for a milder molasses note; dark brown will add a stronger molasses flavor.

Egg — binds the ingredients and adds richness.

All-purpose flour — do not substitute self-rising flour.

Salt and baking powder — provide lift and balance the sweetness.

Vanilla extract — pure vanilla gives the best flavor.

Chopped pecans — use walnuts or omit nuts if preferred.

Chocolate chips — semi-sweet or milk work well.

Recipe Tips

For easy removal, line the pan with a strip of parchment paper that overlaps the sides, then spray it with non-stick spray. Once cooled, use the parchment “handles” to lift the blondies from the pan.

When a recipe calls for nuts, choose unsalted nuts unless otherwise specified to avoid adding extra salt.

Serving Tips

Blondies are delicious on their own, but you can dress them up with:

  • A scoop of vanilla, caramel, or butter pecan ice cream on a warm blondie.
  • A dollop of freshly whipped cream.
  • A drizzle of warm caramel sauce.
  • Sliced fruit such as strawberries, raspberries, or bananas for freshness.
  • A cup of coffee or tea to balance the sweetness.

Presentation Tips

Simple presentation ideas to make blondies look special:

  • Cut into classic squares or use a round cutter for circles.
  • Arrange on a wooden board or pretty plate and garnish with a dusting of powdered sugar, fresh mint, or edible flowers.
  • Layer small cubes in mason jars with whipped cream or caramel for parfait-style servings.

Recipe FAQs

Here are answers to common questions about blondies.

Equipment

  • 8″ x 8″ metal baking pan
  • large mixing bowl
  • measuring cups and spoons
  • whisk

Ingredients

  • ½ cup butter
  • 1 cup light brown sugar, packed
  • 1 egg
  • ¾ cup all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • ½ teaspoon vanilla extract
  • ½ cup unsalted chopped pecans
  • ½ cup chocolate chips

Instructions

  • Preheat oven to 350°F. Spray an 8 x 8-inch pan with non-stick spray. For easy removal, line the pan with a strip of parchment paper that overlaps the sides and spray the parchment as well.
  • Melt the butter in a microwave-safe bowl for about 30 seconds—do not boil. Blend in the brown sugar and egg with a whisk until combined; avoid overmixing.
  • Add the flour, baking powder, salt, and vanilla, and mix until just blended.
  • Stir in the chopped pecans and chocolate chips.
  • Spread the batter into the prepared pan and bake 15–20 minutes, until the edges are golden and the center is just set. Cool before slicing into squares. If you used parchment, lift the blondies from the pan using the parchment handles.

Notes

How to Avoid Sunk-In Blondies

Common causes of underbaked or sunken centers:

(1) Pan type: glass pans bake slower than metal. If using glass, increase oven temperature by 25°F and add 5–15 minutes to the bake time.

(2) Pan size: a smaller pan than 8 x 8 requires more bake time. Check for doneness in 5-minute increments.

(3) Oven temperature: ovens can run cool or hot—adjust bake time accordingly. An oven that’s too hot can set the edges before the center cooks.

(4) Ingredient variations: small changes in butter or flour amounts affect structure, so measure accurately.

Best tip: Bake until the edges are golden and the center looks just set; they will firm up as they cool.
