This blondie is the one I go back to every single time I want a dessert that feels indulgent but doesn’t ask much of me in the kitchen.
It’s a one-bowl bar cookie built on melted butter and brown sugar, so the flavor leans buttery and caramelized instead of purely chocolatey.
If you love the edges of a pan of apple brownies, you already understand the appeal of a bar dessert you can cut into squares and share without any fuss.
That’s exactly what this blondie recipe delivers, just with a butterscotch backbone instead of a cocoa one.
I’ve made this recipe more times than I can count, for potlucks, school bake sales, and lazy Sunday afternoons when I just wanted something sweet in the house.
It always disappears fast, and it’s forgiving enough that a first time baker can nail it.

Why You’ll Love This Blondie Recipe
This isn’t a recipe that needs a stand mixer running for ten minutes or a long list of specialty ingredients.
It comes together in one bowl with a whisk and a spatula.
The texture is what sells people every time, chewy in the center with slightly crisp, golden edges.
That contrast is the whole reason blondies exist as their own category of bar cookie.
- One bowl, no mixer required
- Chewy center with golden, slightly crackly edges
- Ready in under an hour from start to first bite
- Easy to customize with different mix-ins
- Freezer friendly, so you can make a batch ahead
For anyone who already keeps a stash of caramel apple cheesecake bars in the freezer for guests, this blondie recipe is a natural addition to that rotation.
Ingredients
Every ingredient here is doing a specific job, from the melted butter that gives blondies their fudgy chew to the brown sugar that supplies that deep, almost toffee like flavor.
Measure the flour carefully so the bars don’t turn out dense.
- 1 cup (2 sticks) unsalted butter, melted and slightly cooled
- 2 cups light brown sugar, packed
- 2 large eggs, room temperature
- 1 tablespoon vanilla extract
- 2 1/4 cups all purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 2 cups semisweet chocolate chips
- 1 cup chopped pecans or walnuts, optional
- Flaky sea salt, for topping

Kitchen Equipment Needed
Nothing here is specialized. A good metal pan matters more than people realize, since glass pans tend to bake blondies unevenly and can leave the center underdone while the edges overcook.
- 9×13-inch metal baking pan
- Large mixing bowl
- Whisk
- Rubber spatula
- Parchment paper
- Wire cooling rack
I use the same setup I rely on for pumpkin white chocolate chip cookies, since a sturdy metal pan and a good cooling rack cover most of my bar cookie and cookie baking.
Recommended Products for This Recipe
These are the specific products I reach for when I make this blondie recipe.
None of these are required, but they’ve made a real difference in how consistently my bars turn out.
1. USA Pan Nonstick 9×13 Bakeware
This pan heats evenly, which matters a lot for a bar recipe where you want the center fully set at the same time the edges turn golden.
The nonstick coating also makes lifting the parchment-lined bars out of the pan effortless.
2. KitchenAid Stand Mixer
You don’t strictly need a stand mixer for this recipe, but if you bake often, it makes creaming the butter and sugar faster and more consistent.
It’s one of those tools that pays for itself over years of use.
3. Ghirardelli Semi-Sweet Chocolate Chips
The quality of chocolate chips genuinely changes the finished bars.
Ghirardelli holds its shape well during baking and has a deeper flavor than most standard grocery store chips.
4. Maldon Flaky Sea Salt
A pinch of this over the top right before baking gives every bite a small burst of salt against the sweetness.
The flat, crunchy flakes sit on top instead of dissolving in, which is exactly what you want.
5. Reynolds Kitchens Parchment Paper
Lining the pan with parchment and leaving an overhang on two sides means you can lift the entire slab of blondies out in one piece for cleaner slicing.
It also makes cleanup close to instant.
This same approach to ingredient sourcing is part of why my apple cinnamon blondies turn out consistently too. Good basic tools go a long way.
Step-by-Step Instructions: How to Make Blondie
1. Prep Your Pan and Oven
- Preheat your oven to 350 degrees Fahrenheit.
- Line the 9×13-inch metal baking pan with parchment paper, leaving a two inch overhang on the two long sides.
- Lightly grease the parchment so nothing sticks to the corners.
2. Melt the Butter
- Melt the 1 cup of unsalted butter in the microwave or in a small saucepan over low heat.
- Let the melted butter cool for about 5 minutes so it doesn’t scramble the eggs in the next step.
3. Mix the Wet Ingredients
- In a large mixing bowl, whisk the cooled melted butter with the 2 cups of packed brown sugar until fully combined and glossy.
- Add the 2 eggs one at a time, whisking well after each addition.
- Whisk in the 1 tablespoon of vanilla extract.
4. Add the Dry Ingredients
- Sprinkle the 2 1/4 cups of flour, 1 teaspoon of baking powder, and 1/2 teaspoon of salt over the wet mixture.
- Switch to a rubber spatula and fold everything together just until no dry streaks of flour remain.
- Stop mixing as soon as the batter comes together. Overmixing at this stage is the most common reason blondies turn out tough instead of chewy.
5. Fold in the Chocolate Chips and Nuts
- Add the 2 cups of semisweet chocolate chips and the optional 1 cup of chopped pecans or walnuts.
- Fold gently until the chips and nuts are evenly distributed through the thick batter.
6. Spread and Top
- Transfer the batter into the prepared pan.
- Use the rubber spatula or an offset spatula to spread it into an even layer, pushing it into the corners of the pan.
- Sprinkle the top with flaky sea salt.
7. Bake the Blondies
- Bake for 25 to 28 minutes, until the top is golden and set and the edges have started to pull away from the sides of the pan.
- A toothpick inserted in the center should come out with a few moist crumbs, not wet batter.
- Avoid overbaking. Blondies continue to set as they cool, so pulling them slightly early keeps the center chewy.
8. Cool and Slice
- Let the pan cool completely on a wire cooling rack, about 1 hour, before lifting the blondies out using the parchment overhang.
- Transfer to a cutting board and slice into 24 squares with a sharp knife.
The same low and slow bake philosophy shows up in my pumpkin cheesecake brownies, where pulling the pan a touch early is what keeps the center from drying out.
Tips for The Best Blondie
A few small details separate an average pan of blondies from a genuinely great one.
Most of it comes down to how you handle the butter, the flour, and the bake time.
- Use light brown sugar for a milder caramel flavor, or dark brown sugar for something deeper and more molasses forward.
- Spoon and level your flour instead of scooping directly from the bag, which packs in too much and dries out the bars.
- Pull the pan when the center still looks slightly underbaked. It will finish setting as it cools.
- Let the eggs come to room temperature before mixing for a smoother, more even batter.
- Cut with a sharp knife wiped clean between slices for neat squares.

Serving Suggestions
Blondies are rich enough to stand on their own, but a few pairings make them feel more like a planned dessert instead of a quick bar cookie.
Warm slightly and top with vanilla ice cream for an easy sundae situation.
- A scoop of vanilla ice cream and a drizzle of caramel sauce
- A hot cup of coffee for an afternoon treat
- Crumbled over yogurt for a quick breakfast style parfait
- Alongside a plate of Key Lime Pie Bars for a dessert spread with contrasting flavors
- Packed into lunchboxes as an easy homemade treat
Variations of Blondie
Once you have the base batter down, blondies turn into a great template for whatever mix-ins you have on hand.
Swap or add to the chocolate chips without changing the core method.
- White chocolate chips and macadamia nuts for a lighter, sweeter version
- Swirl in peanut butter before baking for a peanut butter blondie
- Add butterscotch chips alongside or instead of chocolate chips
- Fold in toffee bits for extra crunch and caramel flavor
- Mix in dried cranberries and white chocolate for a fall leaning version

Storage and Reheating
These bars hold up well at room temperature and even better in the freezer, which makes them a good make ahead option.
Just keep them tightly covered so they don’t dry out.
- Store at room temperature in an airtight container for up to 4 days.
- Refrigerate for up to a week if your kitchen runs warm.
- Freeze individually wrapped bars for up to 3 months.
- Thaw frozen bars at room temperature for about an hour, or warm in the microwave for 10 to 15 seconds.
- Avoid reheating in the oven for more than a few minutes, since it can dry out the edges.
This works the same way I store leftover orange poppy seed bars, since most bar cookies freeze and thaw the same way.

Health Benefits of Key Ingredients
Blondies are a dessert first, so this isn’t a health food by any stretch.
Still, a few of the ingredients bring some nutritional value along with the flavor.
- Eggs supply protein and choline, which supports normal cell function.
- Pecans and walnuts contain heart healthy unsaturated fats and a bit of fiber.
- Dark or semisweet chocolate has antioxidant compounds called flavanols.
- Butter provides fat soluble vitamins like A and E in small amounts.
I bring up similar nutritional notes whenever I write about smores brownie pie, since bar desserts built on eggs and nuts often carry small nutritional upsides alongside the sugar.
FAQs About Blondie
1. What is the difference between a blondie and a brownie?
A brownie gets its flavor and color from cocoa or melted chocolate, while a blondie relies on brown sugar and butter for its caramel like flavor.
Blondies typically contain no cocoa powder at all.
2. Why did my blondies turn out cakey instead of chewy?
Cakey blondies usually mean too much flour was packed into the measuring cup, or the batter was overmixed once the flour went in.
Spoon and level the flour, and fold just until the streaks disappear.
3. Can I make this blondie recipe gluten free?
Yes, a 1 to 1 gluten free flour blend works well as a direct substitute for the all purpose flour in this recipe.
The texture stays very close to the original.
4. How do I know when blondies are done baking?
The edges should look set and slightly pulled away from the pan, while the center still looks a little soft.
A toothpick should come out with a few moist crumbs rather than wet batter.
5. Can I double this blondie recipe?
You can double the batter and bake it in a half sheet pan, though you will need to add a few extra minutes to the bake time.
Check for doneness starting around the 30 minute mark.
