Essential Ingredients for 4 Ingredient Peanut Butter Cookies

The beauty of these cookies lies in their simplicity. Each ingredient plays a crucial role in creating the perfect texture and flavor. The peanut butter provides richness and moisture, while the coconut sugar gives a hint of caramel-like sweetness. The egg acts as a binding agent, holding everything together, and the baking soda helps the cookies rise slightly, giving them a delightful softness.
- 1 cup peanut butter: This creamy delight is the star of the show, bringing rich flavors and texture.
- 1/2 cup coconut sugar: A natural sweetener that adds depth and a hint of caramel to the cookies.
- 1 egg: Binds the ingredients together, ensuring a chewy cookie.
- 1/2 teaspoon baking soda: This ingredient makes the cookies fluffy and light.
4 Ingredient Peanut Butter Cookies Instructions

Making 4 Ingredient Peanut Butter Cookies is a delightful experience that you can easily enjoy at home. Follow these simple steps to create your very own batch of goodness.
- Preheat the oven to 350ºF and line a baking sheet with parchment paper. This ensures that the cookies won’t stick and will bake evenly.
- In a large bowl, combine the peanut butter, coconut sugar, egg, and baking soda. Mix them until they are well incorporated. The mixture should be smooth and slightly thick.
- Add a pinch of salt if desired. If you’re using unsalted peanut butter, you might want to include between 1/4 to 1/2 teaspoon to enhance flavor.
- Drop the cookie dough by the tablespoon onto the lined baking sheet. It’s a good idea to space them out, as they will spread slightly while baking.
- Use a fork to flatten the dough balls in a criss-cross shape. This classic design not only looks appealing but also helps the cookies bake evenly.
- Once all of the cookies have been flattened, place them in the oven and bake for about 10 to 12 minutes. Keep an eye on them; you want them to be lightly golden but not overbaked.
- When they’re done, let the cookies cool on the pan for about 10 minutes. This helps them firm up before transferring them to a wire rack.
- Transfer the cookies to a wire rack to cool completely. They can be enjoyed at room temperature or placed in the freezer for a firmer texture.
- Store the cookies at room temperature in an airtight container for up to 3 days, or refrigerate or freeze them for up to 3 months.
Things Worth Knowing
- Mixing Technique: Ensure that you mix the ingredients until thoroughly combined, as this will affect the texture of the cookies.
- Thickness Matters: The thickness of your cookie dough will impact how chewy or crunchy the final product is.
- Cooling is Key: Letting the cookies cool on the pan ensures they hold their shape better and are easier to transfer.
- Quality Ingredients: Using high-quality peanut butter can significantly enhance the flavor of your cookies.
Substitutions and Tips

Even though this recipe is simple, there are several tips and substitutions to enhance your baking experience. Here are some suggestions:
- Storage: Store leftover cookies in an airtight container at room temperature to maintain freshness.
