How To Make 4-Ingredient Peanut Butter Cookies

If you love peanut butter cookies but are not a baker or don’t like spending hour baking, this easy cookie recipe is for you.

Ingredients

All you need to make these easy peanut butter cookies are four ingredients that we all have at home.

  • Natural Creamy Peanut Butter – Use a fresh jar with drippy peanut butter for the best result. Natural peanut butter has no added sugar, oil, or salt. You can also use crunchy peanut butter if you enjoy the crunchy bites of peanuts in your cookies.
  • Soft Brown Sugar – White sugar can be used for a crispier texture. I love packed soft brown sugar because it adds a nice flavor and a lightly moist texture in the center of peanut butter cookies.
  • Egg – Pick a large pasture-raised egg.
  • Baking Soda – It adds some soft texture to the cookies.

Optional Flavors

Feel free to add vanilla extract or almond extract in the batter if you like.

Preparation

Preheat oven to 350°F (180°C). Line a large cookie sheet with parchment paper. Oil the paper with cooking spray. Set aside.

In a large bowl, add sugar, egg and vanilla extract. Use an electric beater to beat egg and sugar on low speed until well combined.

Then, add natural peanut butter and baking soda and use a rubber spatula to bring ingredients together. The dough his become dryer as you stir and should form a cookie dough ball after 1 minute.

Baking The Cookies

Divide the cookie dough into 12 smaller balls and place each dough ball onto the prepared baking sheet with parchment paper.

Leave a thumb space between each cookie. They expand slightly in the oven.

Use the back of a fork to press down the top of the cookie dough balls. Then, work in the opposite direction to form a lovely crisscross pattern on top of the flourless peanut butter cookies.

Bake the cookies for 12 to 15 minutes until golden brown on the sides. They should be soft when warm. They firm up as they cool down.

Let the cookies cool down for 10 minutes at room temperature before transferring them to a wire rack to cool completely.

Flavoring Options

You can create a range of flavors using this easy peanut butter cookie recipe.

For example, you can stir in:

  • 1 teaspoon of vanilla extract – at the same time you add egg and sugar.
  • 1/3 cup of chocolate chips at the end

Allergy Swaps

Here are some ingredients you can substitute if you need:

  • Peanut-Free – This recipe works with other nut butter, like almond butter, cashew butter, or sunflower seed butter.
  • Egg-Free – I didn’t test the recipe with egg replacers. I guess you can use a store-bought egg replacer, but I can’t guarantee the result.
  • Baking Soda – You can skip this ingredient, but the cookies are much crunchier.
  • Sweeteners – You can use any crystal sweeteners you like, including white sugar, coconut sugar, or unrefined cane sugar.
  • Sugar-Free – To make keto peanut butter cookies, use brown erythritol instead of brown sugar.

Storage Instructions

Store the cookies in an airtight container for up to 4 days in the fridge. You can freeze peanut butter cookies in ziplock bags for up to 1 month.

Thaw the cookies the day before at room temperature.

Frequently Asked Questions

I listed below the most common answers about this peanut butter cookie recipe.

What Are The Basic Ingredients For Peanut Butter Cookies?

A classic peanut butter cookie is made from egg, natural peanut butter, flour, and sugar.

What Does Baking Soda Do For Cookies?

Baking soda is a leavening agent that creates carbon dioxide helping the cookies rise.
As a result, the cookies are less crispy and a bit softer in the center.

How Do You Keep Peanut Butter Cookies From Falling Apart?

The ratio of egg to sugar in peanut butter cookies is essential but it’s not enough to harden the cookies.
It is crucial to cool down peanut butter cookies twice, first on the baking sheet at room temperature to give them time to firm up before transferring them to a cooling rack for the second cooling.
