Browned Butter Blondies

I found this recipe last week and it immediately went to the top of my to-bake list.  I had all the ingredients, so this morning I made these to take to working wardrobes with me.  We have a big event coming up on Sunday called Blue Jeans & Swing if anyone lives in the Orange County area and wants to attend a great fundraiser that helps men and women in crisis get back to work.   Ill be there volunteering and will probably whip up a yummy treat to bring with me.  Anyway, back to the recipe, its amazing!! It has a very nutty aroma and flavor but it sweet and gooey.  I have only every made 3 types of Blondie's but I think this one is the best!  Its amazing with the toffee bits and walnuts and the browned butter and all the sugar... and vanilla!  You seriously cant go wrong with that flavor combination.  So good!!  I think everyone who tried one today will agree with me...

Browned Butter Blondie's - Adapted from Indulge Bakery
Yield - 24 squares
Ingredients:
1 1/4 Cups (2 1/2 sticks) Unsalted Butter, plus more for pan

2 1/4 Cups Flour, plus more for pan
1 1/2 Teaspoons Baking Powder
1 1/2 Teaspoons Salt
2 Cups Light Brown Sugar, packed
1/2 Cup Sugar
3 Eggs
2 1/2 Teaspoons Vanilla
1 Cup Chopped Walnuts (about 4 ounces)
1 Cup Toffee Bits

Directions:

1. Preheat oven to 350. Butter a 9-by-13-inch baking pan. Line bottom of pan with parchment paper; butter and flour parchment paper.  I just baked it in the pan.
2. In a saucepan over medium heat, cook the butter until it turns golden brown; this happens quick so be cautious, remove from heat, and let cool. 
3. Whisk together flour, baking powder, and salt. 
4. In the bowl of an electric mixer, combine browned butter and both sugars; stir with a wooden spoon until combined. Attach bowl to mixer; add eggs. Using the paddle attachment, beat on medium-high speed until light and fluffy, about 3 minutes. 
5. Add vanilla, and beat to combine. Add flour mixture, walnuts, and toffee bits. Mix until thoroughly combined, and pour into prepared pan.  Smooth out with a spatula.
6. Bake until a cake tester inserted in the center comes out clean, 30 to 35 minutes (do not over bake). Transfer to a wire rack to cool completely before turning out of pan onto a cutting board. Peel off parchment paper; cut Blondie's into 2-inch squares.
7. Enjoy!!
