13x9 Blondies Recipe: Easy, Chewy, and Perfectly Rich

Blondies are a delightful alternative to traditional brownies, offering a rich, buttery flavor with a chewy texture and gooey centers. This 13×9 blondies recipe is straightforward to make and results in a batch that’s perfect for sharing at gatherings or enjoying as an indulgent treat any time. Whether you’re a novice baker or an experienced cook, this recipe guarantees consistently delicious blondies every time.

Ingredients

1 cup (226 grams) unsalted butter, melted
1 1/2 cups (300 grams) packed brown sugar
2 large eggs
1 teaspoon vanilla extract
2 1/2 cups (310 grams) all-purpose flour
1 teaspoon baking powder
1/2 teaspoon salt
1 cup (175 grams) chocolate chips or chunks (optional)
1/2 cup (50 grams) chopped nuts (walnuts, pecans, optional)

Instructions

Preheat your oven to 350°F (175°C). Grease or line a 13×9-inch baking pan with parchment paper for easy removal.
In a large mixing bowl, combine the melted butter and brown sugar. Stir well until smooth and glossy.

Add the eggs one at a time, mixing thoroughly after each addition. Stir in the vanilla extract.
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add this dry mixture to the wet ingredients, mixing just until combined. Do not overmix, as this can lead to tougher blondies.
Fold in the chocolate chips or chunks and nuts if using, ensuring they are evenly distributed throughout the batter.

Pour the batter into the prepared pan, spreading it evenly with a spatula.
Bake in the preheated oven for 25-30 minutes. The blondies are done when the edges are golden brown and a toothpick inserted into the center comes out with moist crumbs—avoid overbaking to keep them chewy.
Allow the blondies to cool in the pan for about 15 minutes, then transfer to a wire rack or cut directly in the pan once cooled for clean slices.

Tips

Substitutions: Use melted butter or margarine if you prefer; for a dairy-free version, substitute with coconut oil or vegan butter.
Mix-ins: Feel free to customize with dried fruits, white chocolate chips, or peanut butter chips for added flavor.
Prevent overbaking: Start checking for doneness at the 25-minute mark to keep blondies moist and chewy.

Storage: Store in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. For longer storage, freeze wrapped portions for up to 3 months.

Serving Suggestions

Serve these blondies as they are for a simple treat, or pair them with a scoop of vanilla ice cream for an indulgent dessert. They also go well with a cup of coffee or tea, making them perfect for brunch or afternoon snacks. For added flair, dust with powdered sugar or drizzle with caramel or chocolate sauce.

Variations

Looking to switch things up? Consider adding swirls of peanut butter or caramel before baking for extra richness. You can also incorporate shredded coconut or dried cranberries for a fruity twist. For a gluten-free version, substitute the all-purpose flour with a gluten-free baking blend that contains xanthan gum.

Storage and Reheating

Stored properly, blondies will stay fresh for up to 3 days at room temperature in an airtight container. If you want to keep them longer, refrigerate for up to a week. To reheat, microwave a single blondie for 10-15 seconds until warm, or reheat the entire batch at 350°F (175°C) for about 10 minutes. Reheated blondies will regain some of their original gooey texture, making them just as delicious as fresh out of the oven.

Frequently Asked Questions

Can I make blondies ahead of time?

Yes, blondies can be baked a day in advance. Store them in an airtight container at room temperature or refrigerate. To enjoy them at their best, bring them to room temperature before serving or warm slightly in the microwave.

How do I know when blondies are done?

The blondies are ready when the edges are golden brown and a toothpick inserted into the center comes out with moist crumbs. They should be slightly soft in the middle but not wet. Overbaking can make them dry, so check early if you’re unsure.

Can I double this recipe for larger gatherings?

Yes, simply double all ingredients and bake in a larger pan, such as a 15×10-inch sheet. Adjust baking time slightly, checking for doneness around 30-35 minutes. Keep an eye on the edges to prevent overbaking.

Are blondies suitable for gluten-free diets?

Traditional blondies are made with all-purpose flour, so they are not gluten-free unless you substitute with a certified gluten-free flour blend. Be sure to use gluten-free chocolate chips and check all ingredients for gluten content.

Can I freeze blondies?

Absolutely. Once cooled, cut blondies into squares, wrap each piece tightly in plastic wrap or foil, and store in an airtight container or freezer bag. They can be frozen for up to 3 months. Thaw at room temperature or warm briefly in the microwave before serving.

What are some common mistakes to avoid?

Overmixing the batter can lead to dense blondies, so mix just until ingredients are combined. Overbaking is another common mistake; keep a close eye on the timer and test for doneness early. Using cold ingredients can also affect texture, so ensure your butter and eggs are at room temperature for a smooth batter.
