Tips For The Perfect Peanut Butter Cookies
Get ready to bake soft, chewy, and golden cookies that disappear right off the pan before they even hit the cookie jar! Here are some tips to nail your flourless peanut butter cookies every time:
- Use creamy peanut butter for a smooth and melt-in-your-mouth texture.
- Mix the dough until just combined- overmixing can lead to dry cookies instead of soft and chewy ones.
- Add a pinch of salt to balance the sweetness of the cookie batter.
- Not a fan of scrubbing trays? Use parchment paper or a silicone mat to keep the tray mess-free.
- For irresistibly chewy cookies, bake them just until the edges are golden and the center still looks slightly underdone.
Make-Ahead Guide For Peanut Butter Cookies
Need to prep ahead for the busy week ahead? These cookies are perfect for making ahead and stashing away for quick and fresh treats later!

Refrigeration
To prepare the dough ahead of time, mix all the ingredients thoroughly and then cover it tightly with plastic wrap or place it in an airtight container. You can store the dough in the refrigerator for up to 3 days this way until you are ready to bake.
Freeze
Before you decide to freeze the whole cookie dough together, stop. You can scoop the dough into individual cookie balls and freeze them separately! Place the balls on a baking tray lined with parchment paper and freeze them for 2 hours.
Once frozen, transfer the balls into a ziplock bag and store them in the freezer for up to 3 months.

One thing you will always find in my kitchen? A big, fat jar of peanut butter that I usually pick up from the local grocery store! Unlike those sugary jams that sneak in all the sugar and preservative stuff, peanut butter is just a jar of pure, wholesome goodness.
Apart from the classic spread on toast, I love tossing it into my smoothies, swirling it into truffles, and of course, whipping up a delicious batch of peanut butter cookies!
Even with such minimal ingredients, peanut butter cookies taste so yummy cause of their core ingredient- Peanut Butter. All the flavor and creaminess without needing extra butter makes these cookies so much easier that I often go for this instead of the fancier, fussier ones.
Plus, peanut butter is super nutritious, so there’s really no excuse to stop at just one, especially when the taste is this ridiculously good and addictive!
Recipe FAQs
Why Do My Cookies Flatten While Baking?
Your cookies may spread while baking because the dough is too warm or soft. Try chilling the dough in the refrigerator for firm and chewy cookies.
How Do I Store Peanut Butter Cookies?
You can store peanut butter cookies in an airtight container at room temperature for up to a week.
Why Do My Cookies Taste So Grainy?
Your cookies may have a grainy texture from the sugar not dissolving properly. Try mixing for a longer time or using finer sugar to solve this issue.
