I stole this from someone's blog. I have forgotten which one.
1 1/2 sticks butter
1 1/2 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon salt
1 cup light brown sugar
1/2 cup dark brown sugar
1 teaspoon vanilla extract
Chocolate chunks or chips
Preheat oven to 350 degrees F. Grease an 8×8″ baking dish. (Line with foil, wax or parchment paper if desired. Grease the lining too.)
Melt the butter in a medium, heavy-bottomed saucepan over medium heat; add both sugars and whisk until combined and sugar is melted, about 5 minutes. (i did this over low heat and it seems to take forever. When I tried it on.medium the sugar clamped. I just stirred occasionally until you can't feel the sugar in your teeth when you taste.it. )
Remove from heat and set aside to cool slightly.
Meanwhile, whisk together the flour, baking powder and salt in a medium bowl.
Next, in a large bowl, whisk together the eggs and vanilla extract until combined. Slowly drizzle in the butter and sugar while whisking constantly. Then add the flour and whisk until just incorporated.
*Now, at this point you could fold in your favorite add-ins: chocolate chips, milk chocolate chunks, nuts, etc. Me? I like mine just plain, baby.
Bake for 25-30 minutes or until the top cracks slightly and is firm to the touch and a toothpick inserted into the center comes out with moist pieces clinging to it. Remove to a wire rack and let cool completely. Or until you can’t stand it any more and have to dig in!
I found the Maple.sauce on a different site.
3/4 cup maple syrup
1/2 cup butter
3/4 cup brown sugar
1/2 Walnuts optional
Melt butter and syrup together. Stir in brown sugar until dissolved like in the blondies recipe. Add Walnuts if using.
