2cupssemi-sweet chocolate chips or chocolate chunks
Instructions
Preheat oven to 325°F. Prepare a 9" x 13" baking pan by lining the bottom and sides with parchment paper. This will allow you to lift the bars out of the pan easily.
In a medium bowl, whisk together flour, salt, and baking soda; set aside.
In a large bowl, whisk together melted butter, brown sugar, and granulated sugar until combined. Add egg, egg yolk, and vanilla, and mix well. Using a rubber spatula, gently fold dry ingredients into the wet ingredients. Add chocolate chips and fold into the mixture until just combined. Be careful not over-mix the batter.
Use a spatula or wooden spoon to bring the dough into the prepared pan covered with parchment paper, then even out the dough and smooth the top with a spatula.
Bake at 325°F for 20-25 minutes. You'll know it's done when the top is a light golden brown and the edges will start to slightly pull away from the sides. Remove from oven and let cool to room temperature on a wire rack before slicing into bars into 2" squares with either a knife or a pastry cutter.
Notes
Makes approximately 18 bars (depending on the size of your slices)You can use foil instead of parchment paper to line the pan, just be sure to grease the foil with cooking/baking spray. My preference is parchment paper; I find it makes removing and slicing through the bars, and clean up, so much easier. When baking, try to avoid using cold eggs. I usually take them out of the fridge as soon as I start gathering my ingredients and let them sit on the countertop for a few minutes before incorporating them. Read this article for more on why you should use room temperature eggs when baking.For chewier bars: remove from the oven before the bars are slightly firm to the touch, around 20 minutes. For crispier bars: remove closer to the 25 minute mark. You can substitute dark chocolate, white chocolate, or milk chocolate chips or chunks, if you prefer.DAIRY-FREE OPTIONS: I make this dairy-free by using my fave vegan butter and dairy-free chocolate chips.
