I love cookies

I mean guys, just look at those cookies!!! I have to tell you, they have a nice chewy center, and the peanut butter flavor just POPS (secret tip: use Crunchy Peanut Butter to add a whole other level of texture and flavor to your cookies!).

These Oatmeal Peanut Butter Cookies are a staple for us, especially on a grey day, in fact I just remade them today for my hubby and I to enjoy so I could update my photos for you guys to drool over.

I can remember when we first started dating I used to make cookies all the time for him to test out, my own little guinea pig, before sharing with family and friends…maybe that’s why he stuck around?!

Now, if you have followed me for long you know that I LOVE cookies and am constantly sharing a new recipe with you! Take for instance my Classic Oatmeal Cookie  or even my Chocolate Crinkle Cookies , both are great examples of a versatile cookie you can adjust to your preferences, and this one is no different guys!

If you prefer to use creamy peanut butter…go for it! Wanna add in some chopped nuts or chocolate chunks..yep you can do that too! Have fun and make em your own! Now, let’s get baking!

Ingredients

  • Peanut butter
  • White sugar
  • Egg
  • Margarine
  • Vanilla
  • Oats
  • Flour
  • Baking powder. 

Tips

  • Use chunky peanut butter – it adds to the texture and gives you a fuller cookie
  • Do not over-mix your batter! Once you have added in the oats you want to do a quick mix and leave it alone
  • You don’t want to cook them until they are brown on top (unless you prefer a very crunchy cookie) you only want the edges to be golden to keep the center chewy
  • Always use quick cooking oats in your cookies, this way you won’t be biting into hard pieces of oats
  • Let them cool for at least 10 minutes before eating one – I know, I know, it’s so hard to just let them be but trust me it’s worth it!

Step-by-step tutorial

Cookie Batter step one

Once your  peanut butter, egg and vanilla have mixed you will be left with a batter that is shiny and thick. You want to make sure that the egg is mixed throughout the peanut butter before moving on to the next step.

Cookie dough step 2 with sugar

Once you add in the sugar and mix to fully dissolve you will have a batter that is more fluffy and pale in color, it almost resembles a whipped peanut butter at this point. Be sure to scrape down the sides of your bowl before adding in the flour mixture with oats in your next step.

Your final mix in of flour and oats will leave you with a wonderfully thick cookie dough that is easily held together with a gentle press. The thick consistency is key to having a  cookie that rises and stays chewy in the center.

Using a teaspoon you want to gently shape the dough into small rounds and place about 1.5″ apart on your cookie tray to ensure they don’t touch when baking.
