How to Store and Freeze 3-Ingredient Peanut Butter Cookies
Room Temperature: Keep cooled cookies in an airtight container at room temperature for up to 3 days, ensuring they stay soft and ready to enjoy.
Fridge: For longer freshness, store cookies in the fridge for up to a week. Just remember to let them come to room temperature for the best texture.

Reheating: To enjoy warm cookies again, reheat in the microwave for 10-15 seconds, making sure not to overheat them, which could dry them out.
Expert Tips for 3-Ingredient Peanut Butter Cookies
- Use Room Temperature Peanut Butter: Soft peanut butter mixes more easily with sugar and egg, creating a smoother dough that bakes evenly without cracks.
- Avoid Overbaking: Remove cookies when edges turn just golden and centers look set but soft to keep them melt-in-your-mouth tender.
- Don’t Skip Parchment Paper: It prevents sticking and browning on the bottom, making clean-up easier and cookies perfectly shaped.
- Customize Texture: Use crunchy peanut butter for added bite or creamy for a classic smoothness—both work beautifully in this simple recipe.
- Mix Gently: Overmixing can toughen the dough; combine ingredients just until blended to maintain soft, tender cookies.
Make Ahead Options
These 3-Ingredient Peanut Butter Cookies are a fantastic option for meal prep, allowing you to enjoy sweet homemade goodness with minimal effort! You can prepare the cookie dough up to 24 hours in advance; simply mix the peanut butter, sugar, and egg, then store it tightly covered in the refrigerator. This keeps the dough fresh and prevents it from drying out. When you’re ready to bake, scoop the chilled dough onto a baking sheet and follow the baking instructions as usual. For added convenience, you can also freeze the formed dough balls for up to 3 months. Just place them on a baking sheet to freeze individually before transferring to a freezer bag. Bake them straight from the freezer when the craving hits for perfectly fresh 3-Ingredient Peanut Butter Cookies!
Easy 3-Ingredient Peanut Butter Cookies That Melt in Your Mouth Recipe FAQs
What kind of peanut butter works best for these cookies?
I recommend using creamy peanut butter for a smooth, tender cookie, but crunchy peanut butter adds a delightful texture if you like a bit of bite. Just avoid natural peanut butter with lots of oil separation unless you stir it really well first.
How should I store leftover 3-Ingredient Peanut Butter Cookies?
Store cooled cookies in an airtight container at room temperature for up to 3 days to keep them soft and chewy. If you want them to last longer, place them in the fridge for up to one week—just bring them back to room temperature before serving for the best texture.
Can I freeze these peanut butter cookies, and how do I thaw them?
Absolutely! Freeze your cookies in a single layer on a baking sheet first, so they don’t stick together. After they’re solid, transfer them to a freezer-safe bag or container. They’ll stay fresh for up to 3 months. To enjoy, thaw cookies at room temperature for about 20 minutes or warm them in the microwave for 10-15 seconds for that fresh-baked feel.
My cookies sometimes turn out dry or crumbly. What am I doing wrong?
Dry or crumbly cookies usually mean the dough was overmixed or baked too long. Mix just until ingredients come together—overmixing tightens the gluten and toughens the dough. Also, watch your bake time closely and remove cookies when edges are just golden and centers still look soft; they’ll firm up as they cool.
Are these cookies safe for pets or people with peanut allergies?
Because peanuts are the star ingredient here, these cookies are definitely not safe for anyone with peanut allergies—and keep them away from curious pets too, as peanut butter can upset some animals. For allergy-friendly treats, I suggest exploring recipes using sunflower seed butter or other nut-free alternatives.
