     Peanut butter oatmeal cookies are chewy and nutty with a creamy peanut butter filling in the middle.

    So..I need to be honest with you. There was a point in my life where I didn’t like peanut butter. At all. I didn’t care for at one tiny bit. But ya know…it grew on me. Kind of like country music. (don’t judge!) Now honestly and let’s not try and be all stereotypical here (and how can we not?)… All in all, can you truly see a Jewish girl next door from Brooklyn skipping away to Chris Young or Rascall Flatts? Well I do and I like it.

    Beastie Boys (Oh, MCA), classic, old-school hip hop from the 80’s. Bob Marley, Journey, Jack Johnson (for some quuiet time), I also have some Blink182 and Green Day (from High School days) and maybe a Run DMC song or 2.

    So I probably and obviously went off track quite a bit. Peanut butter cookies to country music to my Ipod stash. It’s all about the passion and what gets you excited.

    And you know what’s getting me excited at the moment? (Nice transition, huh?) These decadent peanut butter cookies! Yes..I am loving peanut butter all over again. Put on some Beastie Boys and whip me up some peanut butter lovin…I’m in!

    Method:

    1) First, pre-heat oven to 350 degrees and prep 2 non-stick baking sheets.
    In a mixer, beat together sugar and butter until creamy. About 3-4 minutes. Add egg and vanilla extract and beat together until combined.

    2) In a medium bowl, whisk together the oats, flour, baking powder, baking soda, spices, and salt.

    3) Add the dry ingredients to the butter and egg mixture in batches while slowly beating on low speed until just blended. 

    4) Roll and portion about 1 large teaspoon of cookie dough into your hands and place on cookie sheet an inch apart.

    5) Bake cookies for 10 to 12 minutes until lightly golden brown.  Let cool on baking sheet for 5 minutes before filling.

    6) To make the filling, in a mixer, mix together the butter, peanut butter and powdered sugar. Add in the vanilla extract and slowly add in milk, 1 tablespoon at a time until desired consistency. It should be easily spreadable.

    When cookies are completelt cool, spread peanut butter filling on flat side and sandwich similar sized cookie together.

      Ahhh I SO need these right now… Yum! Grand idea. Ps. I couldn’t agree with you MORE about the music these days versus the good stuff. I just can’t listen to the radio anymore. The songs/artists out there that are actually good, get annoying after nonstop radio play.

      Now that I am all riled up, I think I’ll simmer down with some of these sandwich cookies 🙂

      There was a time that I didn’t like peanut butter either. I’m trying REALLY hard to get past it. So, these will probably be therapeutic.

      I like peanut butter in baked goods, but that’s about it! You certainly won’t catch me eating it by the spoonful…

      These remind me of the peanut butter sandwich girl scout cookies. I ate an entire box of them a couple weeks ago, you’re the first person I’m admitting it to. 🙂 It may not be a good idea for me to make these, but I’m going to anyway. 🙂
