These Congo Bars are thick, gooey, chewy, toothsome and the best of the best. Loaded with chocolate chips and rich with caramel flavor, these will be your go to recipe for a simple delicious snack. No mixer required.
Line a 9x13 baking dish with foil or crumpled parchment. Flip the baking dish over, then mold a piece of foil or parchment by pressing it to the underside and sides of the pan. This will shape the foil in the form of the pan. Flip the baking dish back over and place the molded piece of foil or parchment inside. Butter or spray with baking spray.
Combine the flour, baking powder, baking soda, and salt in a bowl and set aside.
In a large mixing bowl, whisk together the melted butter and brown sugar. The butter should be warm (not hot) to melt the sugar slightly. Mix thoroughly until completely combined and smooth. You'll know when it's properly mixed when the mixture pulls away from the sides of the bowl and lightens in color.
Thoroughly beat in the eggs then add vanilla.
Add in flour mixture, chocolate chips, and walnuts (if using) and mix until combined.
Spread evenly into prepared pan and bake for 25 - 30 minutes. Better to slightly under bake than over bake.
