Ingredients
- ½ cup (113 g) salted butter
- 1 cup (200 g) dark brown sugar packed
- ¼ cup (60 ml) vegetable oil (can use canola, corn, or avocado oil)
- 2 large eggs (room temperature)
- 2 ½ teaspoons pure vanilla extract
- ¾ cup (90 g) all-purpose flour (spooned and leveled)
- ¼ teaspoon baking powder
- ⅓ cup semi-sweet chocolate chips (optional)
- ½ teaspoon flaky sea salt (for optional garnish)
How To Make Brown Butter Blondies
Step 1: Brown the Butter
Start by browning your butter.
In a saucepan over medium heat, melt the butter.
Stir it occasionally and keep an eye on it as it turns from melted to bubbly, then to a golden brown color.
You’ll start to notice a lovely nutty aroma – this is what you want! Once it’s browned, remove it from heat and let it cool slightly.
Step 2: Mix the Sugars and Oil
In a mixing bowl, pour in the brown butter.
Add the dark brown sugar and the vegetable oil.
Use a whisk to combine well until it’s all nicely mixed.
You’ll see the mixture become shiny and smooth.
Step 3: Add the Eggs and Vanilla
Next, add the room temperature eggs one at a time, whisking after each addition until fully incorporated.
Then, drizzle in the vanilla extract and give it another good whisk to ensure everything is well combined.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour and baking powder.
Then, gradually add this flour mixture to the wet ingredients.
Mix just until you no longer see any dry flour.
It’s important not to overmix.
Step 5: Fold in Chocolate Chips
If you’re using chocolate chips, fold them into the batter now.
This step is optional, but why would you want to skip chocolate?
Step 6: Bake
Preheat your oven to 350°F (175°C).
Line an 8×8-inch baking pan with parchment paper, leaving some overhang to easily lift the blondies out later.
Pour the batter into the prepared pan, spreading it evenly.
If desired, sprinkle a little flaky sea salt on top.
Bake for about 20-25 minutes, or until a toothpick inserted in the center comes out mostly clean with a few moist crumbs.
Step 7: Cool and Serve
Once done, remove the blondies from the oven and let them cool in the pan for about 10 minutes.
Then lift them out using the parchment paper and place them on a wire rack to cool completely before cutting into squares.
Enjoy your delicious homemade blondies!
Expert Tips
- Use room temperature eggs for better mixing and a fluffier texture.
- Don’t overmix the batter once you add the flour, as this can make your blondies tough.
- For an extra nutty flavor, let the browned butter cool slightly before mixing it with the sugars.
- Store the blondies in an airtight container at room temperature to keep them chewy and fresh.
Variations and Customizations
- Add chopped nuts like walnuts or pecans for a crunchy twist.
- Swap in white chocolate chips or butterscotch chips for a different flavor profile.
- Mix in some dried fruit like cranberries or cherries for a fruity surprise.
- Drizzle chocolate over the top for an extra decadent treat.
How to Store Leftovers
These blondies can be stored in an airtight container at room temperature for up to a week.
You can also refrigerate them if you’d like them to last a bit longer; they can stay fresh for up to two weeks in the fridge.
If you want to save them for an even later date, slice them up and freeze them in a single layer.
Once frozen, transfer them to a freezer bag, and they can last for up to three months.
Just be sure to let them thaw at room temperature before enjoying!
FAQ
Can I use unsalted butter instead of salted butter?
Absolutely! If you prefer unsalted butter, just add a pinch of salt to the batter to balance the flavors.
What can I substitute for brown sugar?
You can substitute light brown sugar or even granulated sugar, but the flavor will be slightly different.
If you have molasses, you can make your own brown sugar by mixing granulated sugar with molasses.
How do I know when the blondies are done baking?
The blondies are done when the edges are set and the center looks slightly underbaked.
A toothpick inserted in the center should come out with a few moist crumbs.
Can I make these blondies gluten-free?
Yes! You can substitute the all-purpose flour with a gluten-free 1:1 flour blend, and the recipe should work just fine.
