The Method for 3 ingredient Peanut Butter Cookies

Step 1: Preheat your oven
Start by preheating your oven to 350°F (175°C). This ensures your cookies bake evenly and achieve that perfect golden color.
Step 2: Mix the ingredients
In a medium mixing bowl, combine 1 cup of peanut butter, 1 cup of sugar, and 1 large egg. Use a whisk or a fork to mix them together until the mixture is smooth and well combined. The dough will be thick, but that’s exactly what you want!
Step 3: Scoop the dough
Using a tablespoon or a cookie scoop, portion out the dough onto a baking sheet lined with parchment paper. Make sure to leave enough space between each cookie, as they will spread slightly while baking.
Step 4: Flatten the cookies
With a fork, gently press down on each cookie to flatten them slightly. You can create a crisscross pattern for that classic peanut butter cookie look.
Step 5: Bake the cookies
Place the baking sheet in the preheated oven and bake for 10-12 minutes, or until the edges are lightly golden. The centers may look a bit soft, but they will firm up as they cool.
Step 6: Cool and enjoy!
Once baked, remove the cookies from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. Enjoy them warm, or store them for later!
Ingredient Flex Options

- Natural peanut butter: Opt for natural peanut butter for a healthier alternative. Just make sure it’s well stirred before measuring.
- Brown sugar: Substitute granulated sugar with brown sugar for a richer flavor.
- Vegan option: Replace the egg with a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water) for a vegan version of these cookies.
- Add-ins: Feel free to add chocolate chips, chopped nuts, or dried fruit for a twist on the classic recipe.
These flex options make this recipe adaptable to your dietary preferences or what you have on hand!
Troubles You Can Avoid
While this recipe is straightforward, a few common pitfalls can be easily avoided:
- Overmixing: Be careful not to overmix the dough, as this can lead to tough cookies.
- Baking time: Keep an eye on your cookies while they bake. Ovens can vary, and you don’t want to end up with overbaked cookies.
- Cooling time: Allow the cookies to cool properly on the baking sheet before transferring them. They need a moment to set.
By avoiding these common mistakes, your 3 ingredient Peanut Butter Cookies will turn out perfectly every time!
Keep It Fresh: Storage Guide
To keep your cookies fresh and delicious, follow these storage tips:
- Room temperature: Store cookies in an airtight container at room temperature for up to one week.
- Refrigeration: For longer freshness, you can refrigerate the cookies, but they might lose some of their chewy texture.
- Freezing: These cookies freeze well! Layer them in an airtight container separated by parchment paper for up to three months. Thaw at room temperature when ready to enjoy.
With proper storage, you can enjoy these cookies for days or even weeks!
Common Questions
Can I use crunchy peanut butter?
Absolutely! Crunchy peanut butter adds a delightful texture to the cookies, giving you those satisfying little bits of peanut in each bite.
What if I don’t have an egg?
You can substitute the egg with a flax egg or unsweetened applesauce. For a flax egg, mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water and let it sit for a few minutes to thicken.
Can I add chocolate chips?
Yes! Adding chocolate chips or chunks is a fantastic idea. Just fold them into the dough before scooping onto the baking sheet for an extra indulgent treat.
Why are my cookies too dry or crumbly?
If your cookies turn out dry, it could be due to too much sugar or overbaking. Make sure to measure your ingredients accurately and check your cookies a minute or two before the suggested baking time.
