It’s no secret I love peanut butter.

Between Peanut Butter Comfort and the peanut butter recipes on my blog, I’ve got hundreds.

Peanut Butter Sandwich Cookie Bars - A creamy PB layer sandwiched between PB cookie dough! Peanut butter lovers will go nuts over these!!

So when there’s a layer of creamy peanut butter fudge sandwiched between peanut butter cookie dough, I’m in my peanut butter glory.

If you like big, bold, unabashed peanut butter flavor with rich, buttery undertones, you’re going to love these.

Last weekย I madeย Fudgy Oatmeal Chocolate Chip Cookie Barsย and had a half can of sweetened condensed milk left. It would have been a shame to throw out 65 cents worth of sweet milkย when I could take a pound of butter and peanut butter and make something new. Makes perfect sense.ย 

The bars are a peanut butter twist on last week’s bars andย I tweaked my trusty no-mixer, easyย blondie baseย by adding peanut butter like I did hereย as well as peanut butter chips.ย Some of the mixture forms the crust and the rest is crumbled on top.

The rich, creamy peanut butter fillingย is made with melted peanut butter chips and a half can of sweetened condensed milk. Make Fudgy Oatmeal Chocolate Chip Cookie Bars,ย 7-Minute Microwave Caramels,ย Peanut Butter Cup Cookie Dough Crumble Bars, orย Milky Way Chocolate Cookie Crumble Barsย with the other half can.

The base layer is extremely soft and moist with while the top layer has more texture. There’s a slight salty-and-sweet vibe too, which I love.

The cookie dough is saltier while the peanut butter fudge layer is sweeter, and it’s a great contrast to bite into, both in terms of texture and flavor.

The bars are hearty, dense, rich, and if you’re having peanut butter cravings,ย they’ll be squelchedย in no time.

Peanut Butter Sandwich Cookie Bars

Thereโ€™s a layer of creamy peanut butter fudge sandwiched between peanut butter cookie bars. The base layer is extremely soft and moist with while the top layer has more texture.

The bars are hearty, dense, rich, and if youโ€™re having peanut butter cravings, theyโ€™ll be squelched in no time.

Ingredients  

  • ยฝ cup unsalted butter, 1 stick, melted
  • 1 large egg
  • 1 cup light brown sugar, packed
  • heaping 1/3 cup creamy peanut butter
  • 1 tablespoon vanilla extract
  • 1 ยผ cups all-purpose flour
  • pinch salt, optional and to taste
  • one 10-ounce bag peanut butter chips, divided (3/4 cup stirred in and 1 cup melted)
  • half of one 14-ounce can sweetened condensed milk, just eyeball it

Instructions 

  • Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
  • In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
  • Wait momentarily before adding the egg so you donโ€™t scramble it. Add the egg, brown sugar, peanut butter, vanilla, and whisk until smooth.
  • Add the flour, optional salt, and stir until just combined, donโ€™t overmix.
  • Addย 3/4 cup peanut butter chips and stir to combine, donโ€™t overmix or theyโ€™ll start to melt.
  • Turn between two-thirds and three-quarters of the doughย out into prepared pan, smoothing itย with a spatula to form a crust; reserve remainder and set aside.
  • In a medium microwave-safe bowl, add the remaining 1 cup peanut butter chips, pour sweetened condensed milk over the top, and heat on high power until the chips melt and mixture can be stirred smooth, about 1 to 2 minutes total, but stop to check and stir every 30 seconds so mixture doesnโ€™t scorch.
  • Evenly pour peanut butterย mixture over crust, smoothing the top lightly with a spatula. Work somewhatย quickly because mixture begins to set up after a couple minutes.
  • Evenly crumble the reserved peanut butter doughย over the top. I find it easiest to make heaping 1-tablespoon-sized โ€˜blobsโ€™, and after all the blobs areย in the pan, smoosh and smooth them together with a spatula. The entire surface willย barely beย covered and there will be some gaps.
  • Bake for about 27 to 29 minutes, or until top is just set; it should be very pale in color for soft bars and the darker it gets, the more crumbly the bars become. Allow bars to cool in pan for at least 1 hourย before slicing and serving. Bars will keep airtight at room temperature for up to 1 week, or in the freezer for up to 6 months.

  1. Those layers look amazing Averie! I love that there is sweetened condensed milk in the center – I can only imagine the gooey factor from that! Pinned :)

  2. These look so delicious! Between the description and photo I feel like I can taste it already! Can’t wait to try this one!

  3. Holy frickin crap girl!! These are absolutely insane! I seriously can’t get enough of all of it– the gooey middle, the buttery cookie top, and the INSANE photography! SO gorgeous!!

    1. You’re too kind! I wore a pink shirt the day I shot these and I feel like they have a toasty warm glow to them :) Whoops. But they tasted great!

  4. This is truly the bar for peanut butter lovers like me. No chocolate, just pure peanut butter flavor! Love it and will be trying it really soon:)

  5. I love your thought process about the half can of sweetened condensed milk–the creativity comes out and nothing is wasted. Sounds like a win-win to me!! As for these incredible bars, might as well go big when it comes to PB. I love layered bars and I bet that fudgy middle becomes a little caramel-y when it bakes.

    1. I grew up so old-school where you did not waste food, period. You found a use for everything! And you re-use your plastic butter containers as tupperware and things like that :) And you are so right about the middle becoming a little caramely. Kind of like a peanut butter dulce de leche of sorts. Loved it!

  6. goodness! They look like monster pb cookie bars and I love monster bars! I mean that middle part is just begging me to munch on in. They look delicious and the perfect afternoon snack

  7. Looks amazing. I only have all natural creamy pb on hand at the moment. Would I need to make any adjustments? Didn’t catch if that was something to consider in the recipe/notes.

    1. I haven’t tried with natural so I can’t say for sure. I think in this recipe, you’d be okay but I haven’t trialed it.

  8. These look like the perfect bar next time a peanut butter craving hits! You make the most amazing bar cookies!
