Ingredients for Brown Butter Blondies
- Unsalted butter (1/2 cup / 113g): Browning the butter creates a rich, nutty flavor with caramel-like notes that make these blondies extra special.
- Vanilla extract (2 teaspoons): Adds warmth and enhances the flavors of the brown butter and chocolate.
- Salt (1/4 to 1/2 teaspoon): Balances the sweetness and brings out the chocolate flavor.
- Brown sugar (1/2 cup packed): Adds moisture, chewiness, and a deep caramel-like sweetness.
- Granulated sugar (1/2 cup): Helps create lightly crisp edges and a delicate crackly top.
- Large egg (1, room temperature): Helps create a smooth batter and soft, tender texture.
- All-purpose flour (1 cup / 125g): Provides structure while keeping the blondies soft and chewy. Measure carefully to avoid a dry texture.
- Dark chocolate (150g / about 1 cup): Creates rich, gooey chocolate pockets throughout every bite.
How to Make Brown Butter Blondies (Step by Step)
1. Prepare the pan
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving some overhang on the sides so the brown butter blondies can be lifted out easily after baking.
2. Brown the butter
Melt the butter in a light-colored saucepan over medium heat, stirring or swirling often. Continue cooking until you see golden brown bits at the bottom and notice a rich, nutty aroma. This usually takes about 5–6 minutes. Be careful not to let it burn.
3. Cool the browned butter
Immediately pour the browned butter into a mixing bowl, making sure to scrape in all those flavorful brown bits from the pan. Let it cool for about 5 minutes before adding the other ingredients.
4. Mix the sugars and flavorings
Whisk the brown sugar, granulated sugar, vanilla extract, and salt into the cooled butter until the mixture becomes smooth and glossy. This step helps create the rich caramel flavor and crackly top of these chocolate chunk blondies.
5. Add the egg
Add the egg and whisk vigorously for about 30 seconds until the mixture looks slightly lighter and well combined. This helps create the soft texture and shiny surface that makes homemade blondies so irresistible.
6. Add the flour
Gently fold in the flour using a spatula until just combined. Avoid overmixing the batter, as too much stirring can make the brown butter blondies dense instead of soft and chewy.
7. Fold in the chocolate
Add the chopped dark chocolate and gently mix until evenly distributed. Reserve a small handful of chocolate pieces to sprinkle on top before baking for extra gooey chocolate pockets.
8. Fill the pan
Spread the batter evenly into the prepared pan and smooth the top with a spatula. Press the reserved chocolate pieces over the surface for a bakery-style finish.
9. Bake
Bake on the middle rack for 20–22 minutes, or until the edges are set and the center looks slightly soft. Avoid overbaking so the chocolate chunk blondies stay chewy and fudgy.
10. Cool and slice
Let the blondies cool in the pan for at least 20 minutes before lifting them out using the parchment paper. For the cleanest slices, allow them to cool completely, then cut into squares and enjoy.
Expert Tips for Perfect Brown Butter Blondies
- Stay close while browning the butter: Browning butter is the most important step for developing that rich, nutty flavor, but it needs attention. The butter can look perfectly golden one moment and burn quickly after that. Keep stirring and watch for golden brown milk solids at the bottom of the pan. Once you smell a warm, toasted aroma, remove it from the heat immediately.
- Use a light-colored saucepan: A stainless steel or light-colored pan makes it much easier to see the butter change color as it browns. Dark nonstick pans can hide the brown specks, making it harder to tell when the butter is ready and increasing the risk of burning it.
- Use a room-temperature egg: Temperature matters when combining the egg with warm browned butter. A cold egg can make the butter seize, creating a lumpy mixture instead of a smooth, glossy batter. Let the egg sit at room temperature for about 10–15 minutes before adding it for the best texture.
- Don’t overbake the blondies: The secret to soft and chewy brown butter blondies is removing them from the oven at the right time. The center should still look slightly soft when they come out because the bars continue baking as they cool. Baking too long can make them dry instead of rich and fudgy.
- Use chopped chocolate instead of chocolate chips: For the best chocolate flavor, choose a good-quality chocolate bar and chop it into chunks. The uneven pieces melt into delicious gooey pockets throughout the chocolate chunk blondies, creating a more bakery-style texture than standard chocolate chips.
- Line the pan with parchment paper: Don’t rely only on greasing the pan. Parchment paper makes removing the blondies much easier and helps you get clean, even slices. Leave a little overhang on the sides so you can lift the entire batch out once cooled.
- Let them cool before slicing: It can be tempting to cut into warm blondies, but allowing them to cool helps the structure set properly. Waiting gives you neat squares with a chewy center and prevents them from falling apart.
- Measure flour correctly: Too much flour is one of the easiest ways to end up with dry dessert bars. Spoon the flour into your measuring cup and level it off instead of scooping directly from the bag to keep these Brown Butter Chocolate Chunk Blondies soft and chewy.
Ingredient Substitutions for Brown Butter Blondies
- Dark chocolate: Swap dark chocolate with semi-sweet or milk chocolate chunks for a sweeter flavor. White chocolate also works well for a different twist.
- Dairy-free butter: Use a plant-based butter like Miyoko’s or Earth Balance for a dairy-free version. The brown butter flavor will be slightly milder but still delicious.
- Gluten-free flour: Replace all-purpose flour with a 1:1 gluten-free baking blend. The texture may be a little softer, so let the blondies cool completely before slicing.
- Egg substitute: Use a flax egg made with 1 tablespoon ground flaxseed and 3 tablespoons water for an egg-free option. The texture will stay tasty, but the crackly top may be less noticeable.
- Brown sugar: Dark brown sugar can be used instead of light brown sugar for a deeper caramel flavor in these brown butter blondies.
- Chocolate options: Chocolate chips or chopped chocolate bars can replace chocolate chunks, but chopped chocolate gives the best gooey texture.
How to Store Brown Butter Blondies
Room Temperature Storage
Store the Brown Butter Chocolate Chunk Blondies in an airtight container at room temperature for up to 4 days. Place parchment paper between layers to prevent the tops from sticking together and to keep the chocolate from making the bars messy. Keeping them tightly covered helps lock in moisture and preserves their soft, chewy centers.
Refrigerator Storage
For longer freshness, store the chocolate chunk blondies in the refrigerator for up to 8 days. The cold temperature will make the texture slightly firmer, which is completely normal. Let the blondies sit at room temperature for about 10–15 minutes before serving so they soften again, or warm them briefly in the microwave for a more gooey texture.
Freezing Instructions
These brown butter blondies freeze beautifully for up to 3 months. Wrap individual squares tightly in plastic wrap, then place them in a freezer-safe bag or airtight container to protect them from freezer burn. When you’re ready to enjoy them, thaw at room temperature for about an hour or overnight in the refrigerator. A quick 15–20 second microwave warm-up will bring back their soft texture and melty chocolate flavor, making them taste almost freshly baked.

Frequently Asked Questions
Can I double this recipe?
Yes, you can double this recipe. Bake the batter in a 9×13-inch pan and add about 8–10 extra minutes to the baking time. Check for doneness by inserting a toothpick into the center; it should come out with a few moist crumbs but no wet batter.
Why did my blondies turn out cakey instead of chewy?
The most common reason is overbaking. These brown butter blondies should be removed from the oven when the center still looks slightly soft and glossy. They will continue setting as they cool, giving you that soft and chewy texture.
Can I use chocolate chips instead of chopped chocolate?
Yes, chocolate chips can be used, but the texture will be slightly different. Chopped chocolate creates larger, gooey pockets of melted chocolate, while chips hold their shape more during baking.
How do I know when the butter is browned enough?
The butter is ready when you see golden brown specks at the bottom of the pan and notice a warm, nutty aroma. This usually takes about 5–6 minutes over medium heat. Remove it from the heat immediately to prevent burning.
Can I make these brown butter blondies ahead of time?
Yes, these blondies are perfect for making ahead. Store them in an airtight container at room temperature, and the flavor may become even richer the next day as the brown butter flavor develops.
Q: Why is my batter greasy or separated?
This usually happens when the egg is added while the browned butter is still too warm. Allow the butter to cool for about 5–10 minutes before mixing to create a smooth, glossy batter.
