Why You’ll Love These Peanut Butter Cookies

  • Classic Taste: Rich, nutty, and perfectly sweet with a chewy texture.

Ingredients for Super Easy Peanut Butter Cookies

The beauty of this recipe is in its simplicity. Here’s what you’ll need:

  • 1 cup peanut butter (smooth, commercial brands like Jif or Kraft recommended for best texture)
  • 1/2 cup white sugar (for balanced sweetness; some recipes use a full cup for extra sweetness)
  • 1 large egg (acts as the binder, creating chewy cookies)

Tip: For extra richness, some bakers add a pinch of salt or vanilla extract, but the classic three-ingredient version is beloved for its pure simplicity.

Step-by-Step Baking Directions

  1. Preheat your oven to 325°F (165°C). Prepare ungreased baking sheets.
  2. Mix ingredients together in a large bowl: Combine peanut butter, sugar, and egg until smooth and fully blended.
  3. Form the cookies: Roll dough into 24 small balls, about 1 inch each. Arrange balls 4 inches apart on your baking sheet—these spread as they bake.
  4. Flatten gently: Use the back of a fork to press a criss-cross pattern onto each ball, gently flattening.
  5. Bake for approximately 20 minutes. Look for lightly browned edges; do not overbake or cookies may become dry and crumbly.
  6. Cool on sheet for 5 minutes before transferring to a wire rack. Let cool completely for best texture and structure.

Tips for Perfect Peanut Butter Cookies

  • Use commercial peanut butter for the best structure; natural peanut butter may cause spreading or crumbly texture.
  • Don’t overmix—blend just until smooth to avoid tough cookies.
  • Do not overbake. Remove from the oven when edges are golden, as cookies will continue to cook slightly on the baking sheet.
  • Want extra flavor? Stir in chocolate chips, sprinkle with sea salt, or add a dash of vanilla extract.

How to Store Your Peanut Butter Cookies

  • Allow cookies to cool completely after baking.
  • Transfer to an airtight container or cookie jar.
  • Store at room temperature for up to 5 days.
  • To keep cookies fresher longer, add a slice of bread to the container—this helps maintain moisture.

For longer storage, freeze dough balls before baking. Bake from frozen, adding a minute or two to the cooking time for warm, fresh cookies on demand.

Common Questions (FAQs)

Can I use natural peanut butter?

Natural peanut butter is oilier and may cause the cookies to spread more or fall apart. Commercial brands with stabilizers yield a more reliable result.

Why do I need to use a fork to flatten the dough?

The dough is thick and does not spread much on its own. Flattening with a fork helps the cookies bake evenly and creates the traditional criss-cross pattern.

Are these cookies gluten-free?

Yes, this recipe is naturally gluten-free since it contains no flour. However, always check that your peanut butter is made in a gluten-free facility if allergies are a concern.

Can I freeze the baked cookies?

Absolutely. Cool completely and store in a freezer bag or airtight container for up to 2 months. Thaw at room temperature before serving; they’ll taste as fresh as when first baked.

What’s the best way to keep these cookies soft?

Store cookies with a slice of bread in the container to retain moisture, or freeze dough balls and bake fresh when ready to enjoy.

Can I double or halve this recipe?

Yes! This recipe is easily scalable. Adjust quantities as needed—just keep the peanut butter, sugar, and egg measurements proportional.

  • Sandwich two cookies with ice cream for a fun dessert.

Frequently Asked Questions (FAQs)

Q: Why are my cookies crumbly?

A: Overbaking is a common cause. Remove cookies from the oven once edges are golden and let them finish setting on the baking sheet for a few minutes before transferring.

Q: Can I use brown sugar instead of white sugar?

A: Yes, brown sugar will give a softer, chewier texture and a subtle molasses flavor. You can also use a combination of both for extra depth.

Q: Are these cookies suitable for kids to make?

A: Absolutely! With only three ingredients and no electric mixer required, this is a great project for kids learning to bake under adult supervision.

Q: Do I need to chill the dough before baking?

A: No chilling is necessary for this quick recipe, although chilling can make dough easier to handle if your kitchen is warm.

Q: What if I want my cookies to be extra soft?

A: Reduce baking time by a minute or two and avoid overbaking. Let them cool completely for the ideal soft, chewy texture.
