Ingredients You’ll Need
Every ingredient in this Chocolate Chunk Blondies Recipe plays an essential role in developing its signature texture and flavor. From the creamy butter that gives it that tender crumb to the blend of sugars that create a perfectly balanced sweetness and chewiness, these simple ingredients come together beautifully to make a bar you’ll want to bake again and again.
- Unsalted butter (1/2 cup, melted): Provides richness and a silky texture—be sure it’s fully melted for easy mixing.
- Brown sugar (1 cup): Adds moisture and a deep, caramel-like flavor crucial to blondies’ character.
- Granulated sugar (2/3 cup): Balances the sweetness and helps with the slightly crisp edges.
- Eggs + 1 yolk (2 eggs + 1 yolk, room temperature): Bind everything together and add richness—room temperature is key for smooth mixing.
- Vanilla extract (2 tablespoons): Infuses the batter with a warm, aromatic sweetness that enhances the chocolate.
- Salt (1 teaspoon): Elevates all the sweet flavors and balances the richness beautifully.
- All-purpose flour (1.5 cups): Provides structure while keeping the blondies tender and soft.
- Chopped chocolate bars (1 cup): The star ingredient—chunks melt into gooey pockets of chocolate and caramel for irresistible bites.
- Instant coffee (a dash, optional): Enhances the chocolate flavor subtly without tasting like coffee.
How to Make Chocolate Chunk Blondies Recipe
Step 1: Prepare Your Oven and Pan
Begin by preheating your oven to 350°F. Make sure to grease your 8×8” metal baking pan or line it with parchment paper for easy removal later. This initial step ensures your blondies bake evenly and come out perfectly shaped every time.
Step 2: Mix the Buttery Sugars
In a large mixing bowl, combine the melted butter with both the brown sugar and granulated sugar. Whisk vigorously for about two to three minutes until the mixture is smooth and creamy—a crucial step that creates the base texture for your blondies.
Step 3: Add the Eggs and Flavorings
Next, whisk in the two eggs plus one yolk that should be at room temperature, making sure to mix until the batter is silky smooth. Then gently incorporate the vanilla extract, salt, and optionally, the dash of instant coffee. The coffee is a secret weapon that deepens the chocolate flavor without overpowering anything.
Step 4: Fold in Flour and Chocolate Chunks
Now, it’s time to fold in the all-purpose flour carefully. Be gentle—only mix until the dry ingredients are just combined to keep your blondies tender and chewy. Finally, stir in the chopped chocolate bars, ensuring those delightful chunks are evenly distributed through the batter.
Step 5: Bake to Golden Perfection
Pour the batter into your prepared pan and spread it out evenly. Slide it into your preheated oven and bake for 25 to 30 minutes, until the edges are set and golden but the center remains soft. Keep an eye on the blondies—overbaking can dry them out, so trust your instincts.
Step 6: Cool Completely Before Cutting
Once baked, allow the blondies to cool thoroughly in the pan. This step lets the texture set and makes cutting easier without crumbling, ensuring you get those perfect squares to enjoy.
How to Serve Chocolate Chunk Blondies Recipe

Garnishes
Sprinkle a tiny pinch of flaky sea salt on top just before serving to highlight the sweetness and add a hint of sophistication. You can also dust with powdered sugar or drizzle a bit of caramel or melted chocolate for an extra indulgent touch that looks spectacular.
Side Dishes
Pair these blondies with a scoop of vanilla ice cream or a dollop of whipped cream for a classic combo that never disappoints. Fresh berries or a drizzle of raspberry sauce also add a bright contrast that balances the richness perfectly.
Creative Ways to Present
Try stacking the blondies with layers of peanut butter or sandwich them with marshmallow fluff for a fun twist. You can even cut them into bite-sized pieces and serve on a dessert platter alongside nuts and fruits for an impressive party display.
Make Ahead and Storage
Storing Leftovers
Keep your blondies fresh by storing them in an airtight container at room temperature. They will stay soft and tasty for up to four days, making them a wonderful make-ahead treat for busy days or last-minute guests.
Freezing
Blondies freeze beautifully. Wrap them tightly in plastic wrap and seal in a freezer-safe bag or container. They maintain their flavor and texture well for up to three months—just thaw overnight in the fridge before serving.
Reheating
To enjoy warm blondies, microwave individual portions for about 15 seconds or heat the whole batch in a low oven (300°F) for 5 to 10 minutes. This revives the melty chocolate and soft, chewy texture perfectly.
FAQs
Can I use chocolate chips instead of chopped chocolate bars?
Absolutely! Chocolate chips work great if you don’t have bars on hand. Chopping bars gives more uneven, melty pockets of chocolate, but chips provide consistent distribution and a reliable melt.
Is it necessary to use both brown and granulated sugar?
Using both sugars creates a wonderful texture—brown sugar adds chewiness and moisture, while granulated sugar helps crisp up the edges. You can experiment, but this blend gives the best results for a classic blondie.
What does the instant coffee do in this recipe?
The dash of instant coffee is optional, but it really amplifies the chocolate flavor without making the blondies taste like coffee. It’s a little trick to deepen richness subtly.
How do I know when the blondies are done baking?
The edges should be golden and set, while the center still looks slightly soft and underbaked. They will firm up as they cool, giving a tender and chewy finish without drying out.
Can I substitute the all-purpose flour for a gluten-free option?
Yes, a 1-to-1 gluten-free baking flour blend should work fine. Be mindful of texture differences and avoid overmixing to maintain tenderness.
Final Thoughts
I can’t recommend this Chocolate Chunk Blondies Recipe enough—it’s one of those crowd-pleasers that’s simple to whip up yet feels so special. Whether you serve it warm with ice cream or pack it for a sweet snack, these blondies bring cozy, chocolaty comfort every time. Give them a try and watch them disappear faster than you’d expect!
