Easy 9x13 Blondies Recipe for Perfectly Chewy Bars

Blondies are a delightful alternative to traditional brownies, offering a rich, buttery flavor with a chewy, dense texture. This 9×13 blondies recipe is simple to make and yields perfectly proportioned bars that are ideal for sharing at gatherings or enjoying as a sweet treat anytime. Its straightforward ingredients and foolproof steps make it a go-to for both beginner bakers and seasoned cooks alike.

Ingredients

1 cup (226 grams) unsalted butter, melted
1 1/2 cups (300 grams) packed light brown sugar
2 large eggs
2 teaspoons 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 a 9×13-inch baking pan or line it with parchment paper for easy removal.
In a large mixing bowl, combine the melted butter and brown sugar. Stir until smooth and well incorporated.

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add these dry ingredients to the wet mixture, mixing just until combined. Do not overmix, as this can make the blondies dense.
Fold in the chocolate chips and chopped nuts, if using. Ensure even distribution throughout the batter.

Pour the batter into the prepared baking pan, spreading it evenly with a spatula.
Bake in the preheated oven for 25-30 minutes, or until the edges are golden and a toothpick inserted into the center comes out with moist crumbs. Avoid overbaking to keep the blondies chewy.
Remove from the oven and let cool in the pan for about 10 minutes. Then, transfer to a wire rack or leave in the pan to cool completely before cutting into squares.

Tips

Substitutions: You can swap the chocolate chips for white chocolate, peanut butter chips, or dried fruit for variation.
Storage: Store blondies in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months. Wrap individual pieces in plastic wrap before freezing.
Common mistakes: Overbaking can make blondies dry; keep an eye on them near the end of baking. Also, avoid overmixing once the dry ingredients are added to prevent dense bars.

For softer blondies: Slightly underbake and let them cool completely in the pan. They will set as they cool and remain chewy.

Serving Suggestions

Serve blondies as they are for a simple sweet treat, or pair them with a scoop of vanilla ice cream for an indulgent dessert. They also make excellent accompaniments to coffee or tea during brunch or afternoon tea sessions.

Variations

Experiment with add-ins like shredded coconut, caramel swirls, or chopped pretzels for a unique twist. For a healthier version, reduce the sugar slightly and add oats or flaxseed. You can also make mini blondies in muffin tins for individual servings or cut into smaller squares for party favors.

Storage and Reheating

Keep leftover blondies in an airtight container at room temperature for up to 3 days. For longer storage, freeze them wrapped tightly in plastic wrap and aluminum foil for up to 3 months. To reheat, microwave a single blondie for about 10-15 seconds or until warm. You can also reheat in a 350°F (175°C) oven for 5-7 minutes for a freshly baked feel.

Frequently Asked Questions

Can I make blondies gluten-free?

Yes, substitute all-purpose flour with a gluten-free flour blend. Be sure to use a blend that includes xanthan gum or add a teaspoon to help with binding. Baking times may vary slightly, so keep an eye on them.

How do I know when blondies are done?

They are ready when the edges are golden brown, and a toothpick inserted into the center comes out with moist crumbs. Avoid overbaking to keep them chewy and moist inside.

Can I add fruit or other mix-ins?

Absolutely! Dried cranberries, chopped dried apricots, or even fresh berries can be folded into the batter before baking. Adjust baking time slightly if adding extra moisture.

What if I want softer blondies?

Slightly underbake by 2-3 minutes and let them cool completely in the pan. The residual heat will finish setting the blondies without drying them out.

Can I double the recipe for a larger batch?

Yes, simply double all ingredients and use a larger baking pan, such as a 9×13-inch or a slightly larger one, ensuring you adjust baking time accordingly. Keep an eye on them to prevent overbaking.

Is there a way to make these vegan?

Yes, replace the eggs with flaxseed or chia seed eggs (1 tablespoon ground seeds mixed with 3 tablespoons water per egg) and use vegan butter or coconut oil. Check that chocolate chips are dairy-free if including them.
