Why The Air Fryer?

Baking cookies in your air fryer is an excellent choice because the air fryer provides a healthier, easier, and quicker way of cooking.

Traditional oven baking is great, but tends to take quite a bit longer and heats your home, which isn’t ideal on a hot summer day!

Peanut butter cookies in the air fryer don’t burn or dry out as quickly as they can in a conventional oven. They come out perfectly round, moist, and chewy!

These easy 3 ingredient peanut butter cookies are a perfect and fun baking project for when you have a few extra minutes to spare in your day. You kids would love to help with these too!

You will never want to go back to traditional oven baking again once you try air frying cookies!

How to Make Air Fryer Peanut Butter Cookies

Step 1: Make Batter

Start by mixing the peanut butter, sugar, and egg together in a large mixing bowl.

Mix well.

Step 2: Section Out Cookies

Place a piece of parchment paper into the air fryer basket, then add about a tablespoon of cookie dough in the center. Use a fork to press down, making the distinctive fork tine marks.

Leave space between each cookie and repeat until the basket is full or the cookie dough runs out. Don’t be afraid to cook in batches — it’s best to leave ample space between each cookie.

Plate, serve, and enjoy!

Pro Tips:

  • Don’t overbake: When you pull your cookies from the air fryer, they will be golden brown at first and then darken in color. Pulling them out once they’re already darker will lead to burnt cookies.
  • Keep your dough cold in between batches: Also, allow your air fryer to cool down before adding more dough.
  • Allow your cookies to rest: These easy 3 ingredient peanut butter cookies are very soft after cooking, so allow them to rest before removing them from the air fryer.
  • Try substituting Greek yogurt for eggs: Greek yogurt is very healthy and packed with protein. It also has a very neutral taste and produces a dense, soft cookie.

Can I Make 3 Ingredient Peanut Butter Cookies in the Oven?

If you don’t have an air fryer, no worries! You can make this 3-ingredient air fryer dessert in your conventional oven as well.

Preheat your oven to 350 degrees F and bake for 10-12 minutes or until the top of the cookie slightly cracks. Let cool and enjoy!

Are 3 Ingredient Peanut Butter Cookies Healthy?

One of these delicious air fryer peanut butter cookies contains only 100 calories, so it can be a great sweet treat for almost any diet.

In comparison, a regular store-bought or bakery peanut butter cookie averages about 200 calories each — double the amount of these air fryer cookies.

Plus, peanut butter contains quite a bit of protein, and so does the egg, so these cookies are pretty filling for being a low-calorie treat!

Why Do These Cookies Have Fork Marks?

Peanut butter cookies are typically dense and won’t spread in the oven. To avoid being cakey, you should press them down with a fork before baking!

If you don’t have a fork readily available, press them down with your fingers or a small glass. They’re going to taste delicious regardless of what texture they have on the outside.

How To Get The Perfect Fork Mark Pattern

I usually use my fork twice — once in each direction. Remember to clean your fork between making marks, so you get the distinctive pattern each time.

You can experiment with using a larger fork or a smaller fork. As long as the cookies are pressed for even cooking, the pattern appearance is up to your preference!

What’s The Best Peanut Butter To Use For These Cookies?

I love a great creamy, salted peanut butter. If you add a sprinkle of sea salt on top, you can make sweet and salty peanut butter cookies in the air fryer.

If you use natural peanut butter or homemade peanut butter, make sure to mix it before adding it to your cookie batter. This way, your peanut butter cookies are a perfect consistency.

What Is The Best Electric Mixer For Cookie Baking?

If you love to bake often, then you may want to invest in an electric mixer. Many bakers love their KitchenAid stand mixers which last forever, so you won’t have to worry about buying another one any time soon — if ever!

However, if the KitchenAid stand mixer isn’t in your budget at the moment, there are many great electric hand mixers available!

Should You Chill The Dough Before Baking?

Yes, keep the dough cold in between air fryer batches. And remember to cool the air fryer in between.

What Happens if You Put a Cookie in an Air Fryer?

If you put a cookie in an air fryer, something truly magical will happen! Your cookie will get warm and soft, gooey, and delicious!

Air fryers are more efficient than regular ovens because they cook quickly and don’t dry out food. The hot air also circulates evenly around the food, so everything cooks evenly.
