These three-ingredient peanut butter cookies are a quick and easy treat that anyone can whip up in no time. With just peanut butter, sugar, and an egg, you can create delicious cookies that are perfect for satisfying your sweet tooth. Whether you're a novice baker or an experienced chef, this recipe is sure to become a favorite.
All the ingredients in this recipe are commonly found in most households. However, if you don't have peanut butter or sugar on hand, you can easily find them at any supermarket. Make sure to get creamy peanut butter for the best texture, and regular granulated sugar will work perfectly for this recipe.

Ingredients For Three Ingredient Peanut Butter Cookies
Peanut butter: This is the main ingredient that gives the cookies their rich, nutty flavor. Use creamy peanut butter for a smooth texture.
Sugar: Granulated sugar adds sweetness and helps to bind the ingredients together.
Egg: The egg acts as a binding agent, holding the dough together and giving the cookies their structure.
Technique Tip for This Recipe
When mixing the peanut butter, sugar, and egg, ensure that the peanut butter is at room temperature. This will make it easier to combine the ingredients smoothly and create a more uniform dough. Additionally, if you prefer a slightly less sweet cookie, you can reduce the amount of sugar to ¾ cup without compromising the texture.

Alternative Ingredients
peanut butter - Substitute with almond butter: Almond butter has a similar texture and nutty flavor, making it a great alternative for those who prefer a different nut or have a peanut allergy.
peanut butter - Substitute with sunflower seed butter: This is a good option for those with nut allergies, as it provides a similar creamy texture and rich taste.
sugar - Substitute with honey: Honey adds natural sweetness and moisture to the cookies, though it may slightly alter the texture.
sugar - Substitute with coconut sugar: Coconut sugar has a lower glycemic index and adds a subtle caramel flavor, making it a healthier alternative.
egg - Substitute with flax egg: Mix 1 tablespoon of ground flaxseed with 3 tablespoons of water and let it sit for a few minutes. This mixture acts as a binder similar to an egg, making it suitable for vegans.
egg - Substitute with applesauce: Use ¼ cup of unsweetened applesauce to replace one egg. This adds moisture and acts as a binder, though it may make the cookies slightly denser.
