The most delicious vegan deep dish peanut butter cookie in existence! Chewy, crunchy, and the perfect combo of crispy edges and a soft, perfect middle. Serve with a scoop of vanilla ice cream and you’re in HEAVEN.



  • 1 1/3 cups all-purpose flour
  • 2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 2 teaspoons cornstarch
  • 1/2 cup olive oil
  • 1 cup granulated sugar
  • 1 cup brown sugar
  • 1/2 cup almond milk
  • 2 teaspoons vanilla extract
  • 1 1/2 cups creamy peanut butter


  1. Preheat oven to 350 degrees F. Lightly oil a cast iron skillet, set aside. 
  2. In a large bowl, whisk together the flour, baking soda, salt, and cornstarch. Set aside.
  3. In a medium bowl, whisk together the olive oil, granulated sugar, brown sugar, almond milk, vanilla, and peanut butter. 
  4. Add the peanut butter mixture to the flour mixture and stir until combined and no flour streaks remain. 
  5. Transfer the dough to the skillet and spread evenly.
  6. Bake for 25-30 minutes, until cookie is golden brown and springs back when lightly touched. 
  7. Allow to cool for 10 minutes before serving. 


  • Use can use natural or traditional peanut butter with this recipe! Natural peanut butter is going to be a bit less sweet, so up the sugar just a bit if you want to add sweetness.
  • Can you bake this in something other than a cast iron skillet? I wouldn’t recommend it! This works best in a skillet because it distributes the heat evenly and just gives it a little something extra.
  • Store this for up to a week, but I know you will eat it long before that!
  • Don’t overbake this cookie! It will make it dry, crumbly, and just not as good. Underbake if you aren’t sure.
