Best Ever Chocolate Chip Blondies
Instructions
1
Preheat the oven to 350°F.
2
Spray an 8-inch square baking dish with nonstick cooking spray.
3
Combine the softened butter, brown sugar, granulated sugar, and vanilla extract in a large bowl. Beat with a hand mixer until pale and fluffy.
4
Add the egg to the bowl and continue to beat on medium speed until light and fluffy.
5
Add the flour, corn starch, baking soda, and salt to the bowl. Beat the mixture on medium speed, scraping down the sides of the bowl with a rubber spatula as needed, until the ingredients are combined.
6
Scrape down the sides of the bowl with a spatula, and add the chocolate chips to the mixture. Fold the chocolate chips into the dough until they are evenly distributed.
7
Transfer the dough to the prepared baking dish and press it into an even layer.
8
Bake the blondies on middle rack of oven until a toothpick inserted in the center comes out clean, about 25 minutes.
9
Check to see that blondies are done. Remove from oven or add time as needed.
10
Allow the blondies to cool at room temperature for a least 15 minutes. Refrigerate for 30 minutes to an hour, then slice and serve.

Tips & Tricks (5)
- Brown Your Butter First 🧈Melt the unsalted butter and let it brown for 2-3 minutes until it smells nutty, then cool slightly before mixing—this adds incredible depth and richness to your blondies.
- Cornstarch is Your Secret Weapon 🌽The cornstarch prevents over-spreading and creates a chewier, more tender crumb—don't skip it or reduce the amount.
- Chill Your Dough 30 Minutes ❄️Refrigerate the batter before baking to prevent excessive spreading and ensure fudgy centers with slightly crispy edges.
- Use Both Sugars for Complexity 🍯The combination of light brown sugar (molasses) and granulated sugar creates complex flavor and the perfect chewy-to-crispy texture balance—using only one will change the results.
- Underbake Slightly for Fudginess 🍫Remove the blondies when the edges are golden but the center still jiggles slightly—they'll continue cooking as they cool, resulting in that irresistible fudgy interior.
