Thick peanut butter chocolate chip bars are made with creamy peanut butter and milk chocolate chips. It's the perfect treat for a fun after-school snack or a quick and easy dessert for parties.
Preheat oven to 350°F. Lightly grease a 9x13 baking dish or line with parchment paper.
In a bowl with an electric mixer or the bowl of a stand mixer, combine the butter and brown sugar for about 30 seconds on medium speed. Add the eggs and vanilla and beat on high until lightened and well combined, about a minute.
Add the dry ingredients and mix on medium-low until combined. Add 1 ½ cups of the chocolate chips and mix just until combined.
Spread dough into the 9x13 baking dish and top with the remaining chocolate chips. Place in the oven and bake for 22-25 minutes, until the edges start to turn golden and a toothpick inserted into the middle comes out clean.
