Oatmeal Bars with Peanut Butter

This peanut butter version is a must-try if you’ve ever enjoyed a chocolate revel bar.

Creamy peanut butter and peanut butter chips bring these oatmeal cookie bars a sweet, nutty flavor.

  • Fast- They can be in and out of the oven in under an hour.
  • Texture- The oats add a chewy texture and a touch of wholesome flavor to the peanut butter cookie base. 
  • Easy- You can whip up the layer of peanut butter fudge quickly with sweetened condensed milk. No candy thermometer is required! 

Another bonus of these peanut butter revel bars is that they freeze wonderfully so you can keep a stack of them on hand for special occasions and surprise gatherings.

If you love today’s recipe, you’ll have to try our butterscotch revel bars next. Same chewy texture, but packed with butterscotch flavor instead of peanut butter!

Or give our chewy caramelitas a try next; oatmeal bars packed with chocolate and caramel!

Ingredients You’ll Need

  • Light Brown Sugar – The molasses in brown sugar makes for a chewy cookie layer with a hint of sweet caramel flavor. You can use a dark brown sugar too if you prefer.
  • Creamy Peanut Butter – Peanut butter is the most important flavor element in the cookie layer! Using creamy peanut butter will ensure your bars are easier to cut, too.
  • Vanilla Extract – Helps achieve that classic peanut butter cookie flavor. Pure vanilla is always best! Or use our homemade vanilla extract.
  • All-Purpose Flour – Gives structure to the cookie layer and topping. Be sure to use our tips and tricks on how to measure flour properly so you don’t end up with dense, dry cookie bars.
  • Quick-Cooking Oatmeal – Adds chewy texture and a hint of hearty flavor to these sweet dessert bars. You can also use
  • Sweetened Condensed Milk – Creates the base of the peanut butter fudge layer, doing most of the work for you.
  • Peanut Butter Chips – The final touch to add rich peanut buttery flavor to the creamy fudge layer of the bars.

How to Make Peanut Butter Oatmeal Bars

What I love about cookie bars is how easy they are to make. Unlike peanut butter cookies, these bars come together so quickly, with just one bake time (no need to make tray after tray of cookies).

  1. Make the cookie dough: Cream the butter, sugar, and peanut butter together until light and creamy. Then mix in the baking soda, eggs, and vanilla. Add the flour and oats last to finish the dough.
  2. Make the peanut butter fudge layer: Heat the sweetened condensed milk and butter in a saucepan until the butter is melted. Then add the peanut butter chips and stir until melted and smooth.
  3. Layer in the pan: Press ⅔ of the cookie dough into the bottom of your prepared pan. Then pour the peanut butter fudge mixture over the top and spread it to all the corners of the pan, making a smooth surface. 
  4. Top it off: Drop the remaining cookie dough evenly in little clumps over the peanut butter fudge layer. It won’t cover the top entirely; it’s more of a crumble.

  • Preheat oven to 350°F. Line a 15x10x1-inch baking sheet with parchment paper. Set aside.
  • In a large bowl, beat 14 Tbsp of butter (reserving the extra two for later), brown sugar, and peanut butter until well blended. Add in baking soda, eggs and vanilla extract. Beat until combined. Add flour and oats and mix until blended. Set aside.
  • In a small saucepan, combine sweetened condensed milk and 2 Tbsp butter. Heat over low heat until butter is melted. Fold in peanut butter morsels and stir constantly until melted and smooth.
  • Press 2/3 of cookie dough into bottom of baking sheet. Keep pressing with your fingertips, it will fit, honest!! Pour peanut butter mixture over top of cookie dough and spread evenly. Drop remaining dough by teaspoon over the top (will not cover completely, that’s okay).
  • Bake for 25-28 minutes until browned. Cool completely. Cut and enjoy. Store in airtight container (best when chilled)!


  • If peanut allergy, substitute Biscoff for the peanut butter, and use white chocolate morsels for the fudge layer!
  • If you’re using a natural peanut butter brand, make sure it’s very well-mixed before using it in the cookie dough. It may alter the consistency of the finished cookie layer. 
  • As you press the cookie dough base into your pan, press it into all the edges and corners. Try to ensure the bottom layer is spread as evenly as possible, so your cookie base has an even thickness throughout.
  • Keep your stove at a low temperature as you warm up the condensed milk, butter, and peanut butter chips. This helps avoid burning the bottom since the main goal is to melt everything together gently.

  1. I end up baking from the same books over and over too!  That peanut butter layer in these bars was to die for!!! I can’t wait to make them again!!!

  2. MMmmm thse looked scrumptious on Instagram ( I think thats where I first saw them). I have never made revel bars but clearly need to!!

  3. I do go back to the same cookbooks again and again. They’re like old friends!
    And these bars are a new friend I need to make!

  4. These bars look amazing! I Love peanut butter, I look forward to trying these. I feel I should double up because I doubt the family would see any of the first batch!

  5. Wow – what a decadent adaptation of those Revel bars you initially found in your Better Homes and Garden Cookbook. These look sinfully delicious – my daughter and her friends would so enjoy these bars! Thanks so much Aimee.
