Step-by-Step: The BEST Blondie Recipe

Step 1: Prepare Your Pan
Start by preheating your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, allowing some overhang on the sides for easy removal later. This will also help prevent sticking.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, combine the melted butter, brown sugar, and granulated sugar. Whisk together until smooth. Then, add in the eggs and egg yolk, followed by the vanilla extract. Mix until everything is well combined.
Step 3: Combine the Dry Ingredients
In another bowl, whisk together the all-purpose flour, corn starch, baking powder, and salt. This step ensures your blondies will have the right texture and rise.
Step 4: Combine Wet and Dry Mixtures
Gradually add the dry ingredients to the wet mixture. Use a rubber spatula to fold the ingredients together gently, being careful not to overmix. This will keep your blondies chewy.
Step 5: Fold in the Chocolate Chips
Once the batter is just combined, fold in your choice of chocolate chips. This is where you can get creative! Use a mix of your favorites for a unique flavor explosion.
Step 6: Bake
Pour the batter into your prepared baking pan and spread it evenly. Bake in your preheated oven for 20-25 minutes, or until the edges are lightly golden and the center is set but still soft. A toothpick inserted into the center should come out with a few moist crumbs.
Step 7: Cool and Serve
Allow the blondies to cool in the pan for about 10 minutes, then lift them out using the parchment paper overhang. Transfer to a wire rack to cool completely before cutting into squares. Enjoy the aroma wafting through your kitchen!
Dairy-Free/Gluten-Free Swaps

- Use dairy-free butter or coconut oil in place of unsalted butter.
- Swap all-purpose flour with a gluten-free 1:1 baking flour blend.
- Ensure chocolate chips are dairy-free if you’re following a dairy-free diet.
Missteps & Fixes
If your blondies turn out too dry, it could be due to overbaking. Keep an eye on them towards the end of the baking time. If they are too gooey, they may need a few more minutes in the oven. Remember, they will continue to cook as they cool.
- Too crumbly? Make sure the butter is melted but not too hot when mixing with sugars.
- Blondies not rising? Check that your baking powder is fresh.
Keep It Fresh: Storage Guide
Store your blondies in an airtight container at room temperature for up to 5 days. For longer storage, you can freeze them for up to 3 months. Just ensure they are wrapped well in plastic wrap and then placed in a freezer bag.
FAQ
Can I add nuts to the blondie batter?
Absolutely! Chopped nuts like walnuts or pecans make a great addition. Just fold them in along with the chocolate chips.
How do I know when my blondies are done baking?
The edges will be golden brown, and the center should be slightly soft. A toothpick inserted into the center should come out with a few moist crumbs.
Can I double this recipe?
Yes! Just use a larger baking pan, such as a 12×18 inch, and adjust the baking time accordingly. Keep a close eye on them as they bake!
Can I use other types of chips or mix-ins?
Definitely! Feel free to experiment with different types of chips like dark chocolate, caramel bits, or even dried fruit. The possibilities are endless!
