All the ingredients for this recipe are commonly found in most households. However, if you don't have peanut butter on hand, make sure to grab a jar from the supermarket.

Ingredients for Three Ingredient Peanut Butter Cookies
Peanut butter: The main ingredient that gives these cookies their rich, nutty flavor. You can use either creamy or chunky depending on your texture preference.
Sugar: Adds sweetness to the cookies, balancing out the savory taste of the peanut butter.
Egg: Acts as a binding agent to hold the cookies together and give them structure.
Technique Tip for This Recipe
To ensure your peanut butter cookies have a uniform texture and bake evenly, make sure to mix the peanut butter, sugar, and egg thoroughly until the dough is completely smooth. This helps to evenly distribute the ingredients, preventing any pockets of unmixed sugar or peanut butter that could affect the final texture. Additionally, when rolling the dough into balls, try to make them as uniform in size as possible. This ensures that all the cookies bake at the same rate, avoiding some being overbaked while others are underbaked.

How to Store or Freeze These Cookies
- Allow the cookies to cool completely on a wire rack. This ensures they are firm and won't break apart during storage.
- Place the cookies in an airtight container. You can use a plastic or glass container with a tight-fitting lid to maintain their freshness.
- If stacking the cookies, place a sheet of parchment paper or wax paper between each layer. This prevents them from sticking together and maintains their shape.
- Store the container at room temperature for up to one week. Keep it in a cool, dry place away from direct sunlight to prevent the cookies from becoming too soft or stale.
- For longer storage, place the cookies in a freezer-safe container or a resealable plastic bag. Ensure all air is removed from the bag to prevent freezer burn.
- Label the container or bag with the date to keep track of their freshness. Frozen cookies can be stored for up to three months.
- When ready to enjoy, remove the desired number of cookies from the freezer and let them thaw at room temperature for about 15-20 minutes. This will bring them back to their original texture and flavor.
- For a warm treat, you can reheat the thawed cookies in a preheated oven at 300°F (150°C) for 5 minutes. This will give them a freshly baked taste and aroma.
