Method: 4-Ingredient Peanut Butter Cookies

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your cookies bake evenly and come out perfectly golden.
Step 2: Combine the Ingredients
In a mixing bowl, combine the natural peanut butter, beaten egg, coconut palm sugar, and vanilla extract. Use a whisk or fork to mix until the dough is smooth and well combined.
Step 3: Scoop the Dough
Using a cookie scoop or a tablespoon, portion out the dough onto a baking sheet lined with parchment paper. Be sure to leave some space between each cookie, as they will spread slightly while baking.
Step 4: Flatten the Cookies
For that classic peanut butter cookie look, use the back of a fork to gently press down on each cookie, creating a crisscross pattern. This not only makes them pretty but also helps them bake evenly.
Step 5: Bake
Place the baking sheet in the preheated oven and bake for 10-12 minutes, or until the edges are lightly browned. The centers may look slightly underbaked, 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 about 5 minutes before transferring them to a wire rack. Allow them to cool completely, then enjoy your delicious 4-Ingredient Peanut Butter Cookies!
Holiday & Seasonal Touches

- Add a pinch of cinnamon or nutmeg for a warm, spicy flavor during the fall and winter months.
- Stir in some chocolate chips or dried cranberries for a festive twist.
- Top with a sprinkle of sea salt right after baking for a sweet and salty combination.
- Shape the cookies into hearts or stars for special occasions like Valentine’s Day or holidays.
What Could Go Wrong
- If your dough is too sticky, it may be due to the peanut butter being too runny. Try refrigerating the dough for 30 minutes before baking.
- Overbaking can lead to dry cookies. Keep an eye on them and take them out when the edges are golden but the centers still look soft.
- If you find your cookies are spreading too much, try chilling the dough before baking to help them maintain their shape.
- Ensure your oven is correctly calibrated, as baking times may vary based on oven performance.
Meal Prep & Storage Notes
These 4-Ingredient Peanut Butter Cookies can be made ahead of time and stored for later enjoyment. Here’s how to do it:
- Store baked cookies in an airtight container at room temperature for up to one week.
- For longer storage, freeze the cookies in a single layer in a freezer-safe bag for up to three months. Thaw at room temperature before enjoying.
- You can also freeze the cookie dough. Shape into balls and freeze. When ready to bake, pop them directly from the freezer into the oven, adding a minute or two to the baking time.
