Ingredients
  

  • ½ cup vegetable oil
  • 3 large eggs
  • ½ cup creamy peanut butter
  • 1 teaspoon vanilla
  • 1 cup granulated sugar
  • 1 cup all-purpose flour
  • ¼ cup cocoa powder
  • ½ teaspoon salt

Instructions
 

  • Preheat the oven to 350°F. Grease an 8-inch by 8-inch baking pan with butter or cooking spray.
  • In a large mixing bowl, combine the vegetable oil, eggs, peanut butter, and vanilla.
  • Add the sugar, flour, cocoa powder and salt. Gently mix everything with a large spoon or silicone spatula just until there are no visible dry ingredients.
  • Spread the batter evenly into the greased baking pan. (The batter will be thick!)
  • Bake for about 25 to 35 minutes, until a toothpick inserted into the center has a few moist crumbs sticking to it, but no wet batter. Let the brownies cool in the pan for at least 20 minutes before slicing. Enjoy!!

Notes

  • Avoid Overbaking: Insert a toothpick into the center to check them. If the toothpick comes out with some moist crumbs but no liquid batter, they're ready to come out of the oven.
  • Storing: I've found that brownies stay more soft and moist when they're uncut, so I cover uncut brownies in the baking dish with plastic cling wrap & store them at room temp. 
  • Dry Brownies: If you have leftover brownies that do end up getting dry and hard, blend them into an epic brownie milkshake with your favorite ice cream!
