S’Mores Cookie Peanut Butter Oat Bars

These S’Mores Cookie Peanut Butter Oat Bars are no bake and taste like a granola bar with a cookie crust!  I used S’Mores Girl Scout cookies to make these bars, but I will give you other cookie options, if you don’t have extra boxes of Girl Scout cookies laying around like I do (please tell me I am not the only one who buys WAY too many Girl Scout cookies every year?!).  These bars are a quick, fun dessert that would be perfect to have on hand for a snack!

I was a Girl Scout for several years growing up, and some of the best memories I have, come from those years of my life.  Plus, my sister was in my troop and my mom was my troop leader, so it was always a lot of fun.  So I know ALL about selling Girl Scout cookies.  And when we sold cookies, it was before social media existed, so that meant we went door to door in our neighborhood taking pre-sale orders, and then camped outside grocery stores peddling boxes of cookies.

So I can never pass up buying cookies from a sweet little Girl Scout….I love everything the Girl Scouts are about.  But I’m gonna be honest….I like home baked cookies over any other kind of cookie.  So that leaves me with a pantry full of Girl Scout cookies, that I buy with the intention of using to make other desserts out of.  Yeah I am dessert crazy 😉  So if you have some Girl Scout cookies left, here’s a great recipe for you!  And if you don’t have any Girl Scout cookies, then you can use any kind of cookie that goes well with the peanut butter, honey, oat mixture that goes on top.  Like….Nutter Butters, Oreo’s (Oooooh the Peanut Butter ones or the Vanilla ones!), graham crackers, Nilla Wafers…I could probably go on and on…but I think you get it!

I used S’Mores Girl Scout cookies for the crust and the amazing Peanut Butter & Co Crunch Time peanut butter in the top layer.  I also used my Mikolich Honey Sage Blossom honey in the top layer with the peanut butter.  And of course my Vain vanilla extract!!  You can use your favorite brand of peanut butter, honey and vanilla extract though!  I just always like to share with you guys the favorite brands I use.  The quality of your ingredients do make a difference, especially in no-bake recipes!

Make your crust first and then pop it in the freezer to set, while you make the top layer.  Just crush up S’Mores Girl Scout cookies and add to melted butter to make this simple crust.

S'Mores Cookie Peanut Butter Oat Bars

Print Recipe
Serves: 20 Cooking Time: 0-minutes


  • 1/2 cup unsalted butter, melted
  • 2 cups of cookie crumbs (I used an entire 9.5-ounce package of S'Mores Girl Scout cookies)
  • 1 cup crunchy or creamy peanut butter (I used Peanut Butter & Co Crunch Time peanut butter)
  • 1/2 cup honey (I used Mikolich Honey Sage Blossom honey)
  • 1/2 teaspoon vanilla extract (I used Vain Ugandan Vanilla Extracted in Premium Vodka)
  • 3 cups old fashioned oats
  • 1/4 cup semi-sweet chocolate chips (optional)



Line an 8-inch x 8-inch baking pan with foil and spray with baking spray. Set aside.




Crush your cookie of choice into crumbs. In a microwave safe bowl, melt the butter. Add the cookie crumbs to the melted butter and stir until combined. Pour cookie crumbs into prepared pan and use the bottom of a drinking glass to firmly press the cookie crumbs into the pan. Place the pan in the freezer for 30-minutes to set.




In a microwave safe bowl, add the peanut butter and honey. Melt mixture in the microwave for approximately 30-45 seconds or until mixture is melted and smooth. Remove from microwave and stir in the vanilla extract. Stir in the oats one cup at a time. Stir until combined and pour oat mixture onto prepared cookie crust. Press oat mixture firmly onto the crust. Sprinkle chocolate chips on top of the mixture and press into the oat mixture.


Place pan in the refrigerator to allow bars to chill and set completely. After bars have set, cut into desired sized squares.


Store bars in an airtight container. Store in the refrigerator for a firmer bar.

I think these bars are like an amped up “granola” bar.  And kinda wholesome because of the honey, peanut butter and oats 😉  These bars have just a thin cookie crust, which adds the perfect amount of sweetness and crunch to these bars.

Top these bars off with some chocolate chips?!  Heck yeah!

I think any kid (or adult) would love to have these bars as an afternoon snack or as a snack after a family hike!  So were you in Girl Scouts or Boy Scouts growing up??  What was your favorite memory from scouting??  Leave me a comment below!

    I think back when I was a girl scout there were only like five cookie options. Are the s’mores cookies new or have I just never noticed them as I reach greedily for the do-si-dos? These bars look AWESOME Kelly! You just can’t go wrong when you use a cookie crust and peanut butter in the recipe. Plus no-bake! Genius 🙂

    Wow! These look seriously delicious. I want one with my cup of tea right now. A perfect midnight snack 🙂 We don;t have girl scout cookies in Australia (our equivalent of girl scouts is called brownies but I wasnt allowed to join 🙁 )scouts sounds like so much fun though) It is on my bucket list though, to go back to America and buy up a whole bunch of them. Especially nutter butters and thin mints.
