Ingredients Needed For Browned Butter Blondies
- 10 Tablespoons unsalted butter: Start with unsalted butter for better control over seasoning. The browning is what adds that lovely, nutty flavor.
- 1 3/4 cups all-purpose flour: This forms the backbone of your blondies. Make sure to fluff and spoon the flour into your measuring cup for accuracy.
- 1/2 teaspoon baking powder: This provides a little lift, resulting in a tender texture.
- 1/2 teaspoon salt: Balances the sweetness and enhances the overall flavors.
- 1 cup brown sugar, tightly packed: Brown sugar gives moisture and that irresistible caramel-like taste.
- 1/2 cup sugar: A mix of sugars adds depth and sweetness that complements the brown sugar.
- 1/3 cup maple syrup: Adds a lovely warmth and depth; opt for pure maple syrup for the best flavor.
- 2 eggs + 1 egg yolk: The extra yolk enriches the batter, leading to that soft, chewy texture.
- 1/2 teaspoon vanilla extract: A classic flavor that rounds out the sweetness of the blondies.
Walnut Topping:
- 1/4 cup all-purpose flour: This helps bind the topping, creating a crumbly texture.
- 3 Tablespoons brown sugar, tightly packed: This enhances the caramel notes in the topping.
- 2 Tablespoons butter: A little melted butter makes the topping rich and tasty.
- 1/2 cup chopped walnuts: These add a nice crunch and nuttiness that complements the blondies wonderfully.
How to Make Browned Butter Blondies
- Preheat your oven to 350°F (177°C) and grease and flour a 9×9-inch pan—this ensures easy release later!
- Cut the butter into tablespoon-sized pieces and melt it over medium-low heat.
- Once melted, increase the heat to medium. Swirl the pan regularly; look for the butter to turn golden brown and develop a nutty aroma. Remove from heat and let it cool for 15 minutes.
- In a medium bowl, whisk together the flour, baking powder, and salt.
- Stir the brown sugar and white sugar into the cooled butter until well combined, then add the maple syrup.
- Add the eggs and vanilla extract, mixing thoroughly until smooth.
- Gradually fold the dry ingredients into the wet mixture until just combined, then pour it into the prepared pan.
- For the walnut topping, pulse the flour and brown sugar in a food processor. Add melted butter and mix until you have coarse crumbs. Stir in the walnuts.
- Sprinkle the topping evenly over the blondie batter and bake for about 35 minutes or until golden and set in the middle.
- Serve warm, ideally with a scoop of ice cream and a drizzle of salted caramel sauce.
How to Serve Browned Butter Blondies
Serve these blondies warm for the ultimate experience! Pair them with vanilla ice cream for a delightful contrast of temperatures, or drizzle some salted caramel sauce for an extra indulgent touch. They also make a wonderful afternoon snack with a steaming cup of tea or coffee.
How to Store Browned Butter Blondies
Keep your blondies in an airtight container at room temperature for up to 3 days. If you want to enjoy them even longer, you can refrigerate them for up to a week. To freeze, wrap individual squares tightly in plastic wrap and store in a freezer-safe bag for up to three months.
Tips to Make Browned Butter Blondies
- Take your time browning the butter: This step is essential for flavor. Don’t rush it, and keep a close eye to avoid burning.
- Don’t overmix the batter: Overmixing can lead to tough blondies. Just mix until the dry ingredients are incorporated.
- Check for doneness: Insert a toothpick into the center; it should come out with a few moist crumbs, not wet batter.
- Customize the toppings: If walnuts aren’t your thing, consider pecans, chocolate chips, or even a sprinkle of sea salt for a sweet-salty twist.
Variations and Substitutions
- Nut-Free: Simply omit the walnut topping or replace it with chocolate chips.
- Extra Flavor: Add a teaspoon of cinnamon or nutmeg to the batter for a hint of spice.
- Gluten-Free: Swap all-purpose flour with a 1:1 gluten-free flour blend.
- Vegan Option: Use vegan butter and flax eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons of water for each egg) instead of traditional eggs and butter.
Frequently Asked Questions
Can I use salted butter instead of unsalted?
Yes, but if you use salted butter, you may want to reduce the added salt in the recipe to keep everything balanced.
How can I tell if my blondies are done baking?
Insert a toothpick into the center; if it comes out with a few moist crumbs, they are done. If it’s wet with batter, let them bake a few more minutes.
Can I make blondies in advance and freeze them?
Absolutely! These blondies freeze well. Wrap them individually and store them in an airtight container for up to three months.
What can I use instead of walnuts?
You can easily substitute walnuts with pecans, almonds, or even enjoy them plain without any nuts for a softer texture.
How do I know if the butter is browned properly?
The butter should turn a deep golden brown and have a nutty aroma. Keep swirling the pan and watch closely to prevent it from burning!
