The Best Ever Chocolate Chip Blondies

04/17/2026 | Bonia Bakery | ,

Let’s be honest for a second: who doesn’t love a good chocolate chip blondie? They’re everything we adore about chocolate chip cookies — buttery, rich, chewy, and packed with melty chocolate — but somehow even easier.

These bars are soft in the center, perfectly golden around the edges, and have that irresistible crackly top that makes you want to grab a square the second they come out of the pan.

I’m calling these The Best Chocolate Chip Blondies for a reason. They’re incredibly chewy, deeply buttery from the brown sugar, and loaded with chocolate chips in every single bite. The centers stay soft and slightly gooey while the edges bake up just enough to give that perfect blondie texture. It’s the kind of dessert that somehow disappears faster than you expected… because everyone keeps “just taking one more piece.”

Another reason these blondies are the best? They’re ridiculously easy to make. No scooping dough, no rolling cookie balls, no baking tray after baking tray of cookies. Everything comes together in one bowl, gets spread into a single pan, and baked all at once. It’s the lazy baker’s dream — and honestly, sometimes blondies are just better than cookies for that reason alone.

They’re also perfect for pretty much any occasion. Bring them to a party, cut them into squares for brunch, pack them for a picnic, or keep a batch on the counter for late-night sweet cravings. They’re simple, nostalgic, and guaranteed to make people happy. Because really… who can resist a warm, chewy chocolate chip blondie?

Why We Use These Ingredients

Each ingredient in these blondies plays an important role in creating that chewy, buttery texture.

  • Unsalted Butter – Melted butter gives blondies their rich flavor and dense, chewy texture.
  • Light Brown Sugar – Adds sweetness and moisture while creating that classic caramel-like blondie flavor.
  • Egg + Egg Yolk – The extra yolk adds richness and chewiness while the egg provides structure.
  • Vanilla Extract – Enhances the warm, sweet flavor of the blondies and pairs perfectly with chocolate.
  • Baking Powder – Gives the blondies just a little lift so they aren’t overly dense.
  • Salt – Balances the sweetness and intensifies the chocolate flavor.
  • All-Purpose Flour – Provides the structure that holds everything together.
  • Chocolate Chips – The star of the show, creating pockets of melty chocolate throughout the bars.

How to Get Perfect Chocolate Chip Blondies Every Time

A few simple tips will ensure your blondies turn out bakery-quality every time.

  • Don’t overmix the batter. Overmixing can make the blondies tough instead of chewy.
  • Use melted butter that has slightly cooled. Hot butter can scramble the eggs if added too quickly.
  • Line your pan with parchment paper. This makes lifting and slicing the blondies much easier.
  • Slightly underbake the center. The middle should look a little soft — it will firm up as the bars cool.

Why You’ll Love These Blondies

There are so many reasons these bars are a favorite.

  • One-pan recipe – No cookie scooping required.
  • Super chewy texture – Soft centers with lightly crisp edges.
  • Loaded with chocolate chips – Every bite is full of chocolate.
  • Perfect for sharing – Great for parties, bake sales, brunch, or dessert.

Pro Tips for the Best Blondies

These small tricks make a big difference.

  • Use good-quality chocolate chips for the richest flavor.
  • Let the blondies cool before cutting so they set properly.
  • Sprinkle extra chocolate chips on top before baking for a bakery-style look.
  • Cut with a sharp knife for clean squares.

Ingredients

Blondies

  • ½ cup unsalted butter, melted (113 g)
  • ¾ cup packed light brown sugar (150 g)
  • 1 large egg, room temperature (50 g)
  • 1 large egg yolk, room temperature (18 g)
  • 2 teaspoons vanilla extract (10 g)
  • ¼ teaspoon baking powder (1 g)
  • 1 teaspoon salt (5 g)
  • 1 cup all-purpose flour (120 g)
  • 1 cup chocolate chips (170 g)

Directions

  1. Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper.
  2. In a large bowl, whisk together the melted butter and brown sugar until smooth.
  3. Add the egg, egg yolk, and vanilla extract, whisking until fully combined.
  4. In a separate bowl, stir together the baking powder, salt, and flour.
  5. Add the dry ingredients to the wet ingredients and fold until just combined and no streaks of flour remain.
  6. Fold in the chocolate chips, being careful not to overmix.
  7. Pour the batter into the prepared pan and spread into an even layer.
  8. Bake for 25–30 minutes, or until the blondies are golden brown, set around the edges, and slightly puffed. The center may still look a little underbaked — that’s perfect, as they will continue to cook as they cool.
  9. Allow the blondies to cool completely, then cut into squares and enjoy.
