Preheat the oven to 350°F (180°C).
Grease an 8x8 inch square pan with a nonstick oil spray or butter.
Then line it with parchment paper, and keep the parchment paper hanging over both sides. Set it aside.
Roughly chop the lightly toasted almonds, take ¼ cup from it, and set it aside for topping.
Whisk flour, baking powder, and salt together in a medium bowl. Add ½ cup chopped almonds and chocolate chunks, and mix well.
In a medium bowl, whisk browned butter, brown sugar, and vanilla together until well combined.
Add dry ingredients and milk to the wet mixture and stir until everything is well combined. The batter will be pretty heavy and thick.
Transfer the batter to the prepared baking pan, and spread it evenly. Top the batter with the remaining ¼ cup of chopped almonds, and lightly press with a spatula.
Bake the blondies in the oven for 22-26 minutes or until a toothpick inserted in the center comes out almost clean.
Remove from the oven and place the pan on the cooling rack. Let it cool completely in the pan, then remove and cut into the desired size of squares.
