Kitchen Tools for Classic Blondies
- 9×13-inch baking pan
- Mixing bowls
- Whisk or spoon
- Parchment paper
Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon salt
- 1 cup unsalted butter, melted and slightly cooled
- 1 cup light brown sugar, packed
- ½ cup granulated sugar
- 2 large eggs, room temperature, lightly beaten
- 2 teaspoons vanilla extract
- 1¼ cups white chocolate chips
- ½ cup chopped walnuts or pecans (optional)

How to Make Classic Blondies
Step 1. Begin by preheating your oven to 350 degrees. While the oven heats, lightly coat a 9×13-inch baking pan with nonstick cooking spray. For easy removal later, line the pan with parchment paper, leaving some overhang. This will provide enough lift to take the blondies out once they’ve cooled.
Step 2. In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. This mixture is essential as it helps to bring some structure to the blondies while allowing them to rise gently in the oven.
Step 3. In a larger bowl, combine the melted butter with the packed light brown sugar and granulated sugar. Stir them together until the mixture is smooth and fully blended. Adding the beaten eggs and vanilla extract at this stage will add moisture and a rich flavor, enhancing the overall taste of your blondies.
Step 4. Gradually incorporate the dry ingredients into the wet mixture. It’s best to do this in several intervals, stirring gently just until combined. You want to avoid overmixing here, as that can lead to a denser texture, instead of the deliciously chewy blondies we’re aiming for.
Step 5. Once your batter is mixed, fold in 1 cup of the white chocolate chips and the chopped walnuts or pecans if you’re using them. This step adds not only flavor but also a bit of crunch. After everything is evenly combined, spoon the batter into your prepared baking pan, spreading it out evenly.
Step 6. To finish, sprinkle the remaining white chocolate chips on top of the batter before you place the pan in the oven. Bake until the edges are lightly browned and pulling away from the sides of the pan. When done, a toothpick inserted into the middle should come out mostly clean, with just a few moist crumbs clinging to it.
Step 7. It’s important to let the blondies cool completely before slicing them into squares. This waiting period ensures that they set properly, giving you that perfect chewy texture.

Serving Ideas for Classic Blondies
These blondies make for a fantastic snack any time of day, whether you want a sweet treat to go with your afternoon coffee or a simple dessert after dinner. They can also be an easy addition to a potluck spread. Leftover blondies, stored in an airtight container, can be enjoyed for several days, making them a convenient option for when you need a quick indulgence. Serve them plain, or add a scoop of vanilla ice cream on the side for extra sweetness.
Practical Tips for Classic Blondies
- Use room-temperature eggs for better incorporation into the batter.
- Ensure your butter is slightly cooled before mixing to prevent cooking the eggs.
- Avoid overmixing the batter to keep the texture light and chewy.
- Allow the blondies to cool fully in the pan for the best slicing results.
- Experiment with different nuts to find your favorite combination.
- Store in an airtight container to maintain freshness.
Common Mistakes to Avoid
- Overmixing the Batter: Overmixing can lead to tough blondies. Stir just until the dry ingredients are incorporated for a soft, chewy result.
- Not Measuring Flour Correctly: Packing flour can lead to denser blondies. Use the spoon-and-level method: spoon the flour into the measuring cup and level it off with a straight edge.
- Skipping Parchment Paper: If you skip lining the pan, you might have a hard time getting your blondies out intact. Always use parchment for easy removal.
- Using Cold Eggs: Cold eggs can cause the batter to seize up, creating uneven baking. Always use room temperature eggs for the best results.
- Not Allowing to Cool: Cutting into the blondies too soon can result in them falling apart. Patience is key; let them cool before slicing for neat squares.
- Inaccurate Baking Time: Every oven is different. Keep an eye on your blondies towards the end of the baking time to avoid overbaking and drying them out.
Simple Variations
If you enjoy different flavor profiles, consider adding a mix of dark chocolate chips or toffee bits in addition to the white chocolate. For a touch of spice, a pinch of cinnamon or nutmeg can elevate the overall flavor. Feel free to swap out the nuts or adjust the amount of chocolate chips based on preference.
Storage & Reheating
Store your blondies in an airtight container at room temperature for up to five days. If needed, they can also be kept in the refrigerator, though this may alter their texture slightly. For long-term storage, wrap them tightly in plastic wrap and place in the freezer. To enjoy, simply thaw at room temperature or microwave for a few seconds to regain that fresh-baked warmth.
