- Preheat the oven to 350°F. Grease an 8×8 pan. For easy removal of the brownies, place parchment paper on the bottom and 2 sides of the pan. Grease again and then set aside. 
- Melt the butter and cool for 10 minutes. Then, add into a large bowl and whisk in sugar. - 1/2 cup butter, 3/4 cups dark brown sugar 
- Add in egg and vanilla and continue whisking.  - 1 egg, 1 tbsp vanilla 
- Toss in flour and salt and use a spatula to gently fold until no dry streaks appear. - 1 cup all-purpose flour, 1/2 tsp salt 
- Toss in chopped up Snickers and chocolate chips. Mix in a few times. - 2 regular-sized Snickers bars, 1/2 cup semi-sweet chocolate chips 
- Transfer into prepared pan and spread out evenly. Top off with extra Snicker pieces and chocolate if desired. 
- Bake for about 22 to 26 minutes, or until the top looks set. Inserting a toothpick in should result in a few crumbs and not batter. 
- Blondies firm up as they cool, so allow them to sit on your counter and come down to room temperature. Slice and enjoy!
