How To Make Peanut Butter Cookies

To start, cream the butter and sugars.  Beat in the egg and vanilla next.

Stir in the peanut butter then start adding the dry ingredients and M&M’s until dough forms.

Place your dough onto a parchment lined cookie sheet.  I shape the dough into a nice round and top with a handful more mini M&M’s.

Bake the cookie for 12-15 minutes, until baked through, edges start to turn golden brown.  Right after cookie is removed, take a knife and go around the edges to make a perfect round cookie if you’d like.  I do this all of the time.  It’s very shapable right out of the oven.

Tips For Making The Best Cookies

  1. Don’t alter the recipe, use all ingredients as listed.
  2. For a more firm cookie, refrigerate your cookie dough for 24 hours before baking.
  3. Always use butter, not margarine.  ALWAYS.  I prefer salted butter for my chocolate chip cookies.  Try it!
  4. Do not ever grease your cookie sheets.  Will make cookies spread and change texture.
  5. Don’t skip creaming your butter and sugars for a good 2 minutes.  Helps create a fluffy, chewy cookie.
  6. Try sprinkling dough with just a touch of salt for a perfect sweet and salty combination.
  7. Don’t overtake your cookies.  Cookies will continue to cook on hot cookie sheet when removed from oven.
  8. Let cookies cool completely before storing in containers. This will keep their crispness
  9. Store leftover cookies in an airtight container for 3 days room temperature.
