Peanut butter cookies have always held a special place in my heart. From little on, peanut butter cookies were always made by my mom with love for our family. I’ve already perfected the Best Vegan Peanut Butter Cookies, so I set out to do something a little, uh, bigger, if you will. When I had the opportunity to make a deep dish peanut butter cookie, you can bet I was all the way in. I can’t believe I didn’t think of it sooner! It’s a super simple recipe and I bet you already have most of the things you need in your pantry.

How to make deep dish cookie

One of my favorite things about this recipe is the no-fuss factor! I’ve seen plenty of recipes that make you jump through hoops when all you need to do is start with a solid base. I promise that this easy skillet cookie recipe will be as tasty as it is effortless.

You start out whisking the flour, baking soda, salt, and cornstarch together. It’s important to not skip this step because it ensures that all of these dry ingredients mix together and distribute evenly. In another bowl, whisk the olive oil, granulated sugar, brown sugar, almond milk, vanilla, and peanut butter together. Combine both mixtures until they’re thoroughly blended, spread it in the skillet, and bake for about 25-30 minutes!

When you take it out of the oven, it should slightly spring back when you touch it. That’s how you know it’s done!

Why are my peanut butter cookies crumbly?

If your deep dish peanut butter cookie is coming out crumbly, it’s likely they’re too dry. Oops. It’s totally fine and fixable, so don’t worry too much.

When so many dry ingredients are added, it’s necessary to make sure you’ve got enough ingredients to add wetness to the batter. Try adding a little more milk or oil to the mixture and see if that helps the dough hold together.

Can you make peanut butter cookies with natural peanut butter?

You can absolutely make this deep dish peanut butter cookie with natural peanut butter! The only kicker is that natural peanut butter is likely just ground peanuts and maybe a little palm oil. If you use natural peanut butter, I’d recommend adding in a little sugar and a pinch of salt to enhance the flavoring of the peanuts.

What can I bake in a cast iron skillet?

Giant cookies! Kidding. You can do more than giant cookies, but what a great place to start! You can bake pies, cornbread, biscuits, frittata, pizzas – really almost anything goes here.

If you’re more of a chocolate person, you can try baking my Vegan Deep Dish Chocolate Chip Cookie for dessert! Or breakfast. Who am I to judge??

How to store skillet cookie

Nobody likes stale cookies! If for some insane reason, you don’t eat this cookie in one sitting, there’s a right and wrong way to store it. Properly storing your cookie can preserve the quality of cookie for extended days of tastiness.

It’s recommended that you store your skillet cookie covered at room temperature. For maximum freshness, enjoy your cookie within 5-7 days of cooking it. Or you could just be an overachiever like me and eat it all at once. Totally your call.

How to reheat skillet cookie

Sometimes cookies just taste better heated up! If you’re someone who loves a warm, gooey cookie, then this section is for you!

You can reheat your skillet cookie by sticking in the oven at 350 degrees for about 15-20 minutes. If you don’t want to reheat the whole thing, you can slice it into individual pieces and microwave it for a short time, like 10-15 seconds.

Scale

Ingredients

  • 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 brown sugar
  • 1/2 cup almond milk
  • 2 teaspoons vanilla extract
  • 1 1/2 cups creamy peanut butter

Instructions

  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. 

Notes

  • 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.
