These cookies puff up quite a bit while baking. If you want a flatter cookie, just press the tops with the bottom of a cookie spatula just after baking.

Baking Tips

  1. Use creamy peanut butter. JIF, Skippy, or other similar brand. Natural peanut butters tend to make dry, crumbly cookies. Chunky peanut butter is okay, but may also result in a slightly drier cookie.
  2. Use old fashioned oats. While quick cooking oats will work about the same, the texture of the cookie will be slightly more dense.
  3. Stir the flour before measuring it. Flour settles and compacts as it is stored. It is vital to stir (fluff up) the flour to incorporate air before measuring it. This prevents a dense, dry baked product.
  4. Do not over-bake. These peanut butter oatmeal cookies will brown on the bottom well before they brown on top. To achieve a soft, chewy cookie, remove them from the oven when the edges are set but the middles are still soft. Allow them to cool and finish baking on the cookie sheet for a few minutes before transferring them to a wire rack.
  5. Storing: These cookies can be kept in an airtight container at room temperature for several days. To Freeze: Place cooled baked cookies in a freezer bag and freeze up to 2 months. May also freeze cookie dough in balls on a cookie sheet. Once frozen, transfer to a freezer bag. To bake from frozen, add 2 to 4 extra minutes baking time.
