Brown Butter Toffee Blondies

Next up in our Brownies, Blondies, Blondie Brownies recipe series: Brown Butter Toffee Blondies Recipe. Glen 'found' some Mackintosh's Toffee at the grocery store and thought it would be the perfect addition to a brown butter blondie brownie recipe... and he was right!
Ingredients:
1 cup (250 mL / 230g) unsalted butter
2 cups (500 mL / 320g) all-purpose flour
1 tsp (5 mL / 7g) coarse salt
2 eggs
4 tsp (20 mL) pure vanilla extract
1 3/4 cups (315g) dark brown sugar
1 cup (250 mL / 150g) toffee bits


Method:
Preheat oven to 350°F (180ºC).
Grease an 9x9" baking pan and line with a parchment paper sling.
Brown the butter over medium heat.
Stir occasionally, it will foam and spatter as the water content 'boils' off.
The butter is ready when the foaming stops and you see brown bits at the bottom of the pan.
Pour into a large bowl and allow to cool.
Whisk together flour and salt.
In a stand mixer, whisk together eggs and brown sugar.
When light and frothy whisk in vanilla and the cooled butter.
Add flour mixture to the butter/sugar/egg mixture, and mix just until combined.
Add the toffee bits.
Mix until evenly distributed, but be careful not to over-mix!
Scrape dough into your prepared baking pan and spread into the corners.
Bake for 25 to 30 minutes.
You'll know it's done when you see a crispy top that's just starting to crack with firm slightly-browned edges.
Remove from the oven.
Cool completely before removing from the pan.
