Blondies are sort of the anti-brownie in color and philosophy yet they are still brownie-like in their essential makeup. These chocolate coconut blondies are sweet, cakey, and delicious.
Preheat oven to 350℉. Butter an 8-inch square baking pan and line with parchment paper, leaving two flaps hanging over the edges of the pan. Butter and flour the parchment paper.
In a medium bowl, whisk together the melted butter and brown sugar. Whisk in the eggs one at a time and beat by hand until mixture is slightly pale, about 2 minutes. Whisk in the vanilla extract.
In another medium bowl, whisk together the flour, baking powder, baking soda, and salt. Add all at once to the butter and sugar mixture and stir until just incorporated. Fold in the coconut, chocolate, and walnuts.
Spread batter into the prepared pan and smooth with a spatula. Scatter the remaining chocolate and walnuts across the top. Place in the oven and bake for 20 to 25 minutes, or until a skewer inserted in the center comes out clean. Blondies will be golden brown.
Remove pan from oven and allow to cool for at least 20 minutes before removing blondies from the pan. Slice into pieces lengthwise and crosswise, making them as large or small as you like.
