When I was growing up we had Peanut Butter Fingers as a dessert/treat with our school lunch! I loved school lunch, and loved all the desserts they gave us. The yellow cake with chocolate frosting along with these Peanut Butter Fingers were my favorite!

The Peanut Butter Fingers (that’s what we called them at my elementary school and I have no idea why) are just like most Peanut Butter Bar recipes out there!

I have never made other recipes because this has been my go-to recipe ever since I was a kid and my best friend Ali and I were allowed to cook and bake in the kitchen.

Peanut Butter Fingers are easy to make in a mixer and will whip up in minutes. You can mix them by hand, but why make extra work for yourself?

Add the softened butter and sugars, mix until blended well. Then add the the rest of the ingredients, making sure they are fully blended. (The original recipe called for 2/3 a cup but I prefer at least 3/4 cup or more! So add as much or as little as you like, but more is better, trust me!)

Press into a greased baking sheet. I use a half sheet pan and this is the perfect size!

Bake at 350 degrees for 15 minutes. They are done when edges start to brown and a toothpick comes out fairly clean when poked in the middle. I like mine a bit underdone so I pull mine out a few minutes early.

Let them cool while you make the chocolate frosting.

THE FROSTING

The chocolate frosting is just as easy to make and the amount of cocoa can be adjusted to your liking!

Mix the softened butter, vanilla, milk, cocoa and powdered sugar together. If you need to thin it out, add a bit more milk. If you want it thicker, add more powdered sugar. If you want it a more rich chocolate flavor, add more cocoa!

Frost the Peanut Butter Fingers once they have cooled! For some more peanut buttery goodness you can add a layer of creamy peanut butter before frosting them with the chocolate frosting!

Author Beth, The Butcher’s Wife

Ingredients

  • 1 cup butter, softened (2 sticks)
  • 1 cup white sugar
  • 1 cup brown sugar
  • 2 eggs
  • 1 tsp vanilla
  • 3/4-1 cup Creamy Peanut Butter *I use about 3/4 cup but you can add up to 1 cup for more Peanut Butter taste yummy
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 2 cups flour
  • 2 cups Quick oats (oatmeal) see notes

Chocolate Frosting

  • 1/2 cup butter, softened (1 stick)
  • 1/2 cup milk
  • 1 tsp vanilla
  • 5 to 6 tbsp unsweetened cocoa (add more or less to your liking)
  • 5 to 6 cups powdered sugar (add more or less to your liking and how thick you want it-see notes)

Instructions

  • Preheat the oven to 350 degrees.
  • In a mixer (or by hand), mix the butter and sugars together. Then add in the rest of the ingredients making sure they are fully mixed.
  • Press the dough in to a greased half sheet/jelly roll pan.
  • Bake in oven for 15 minutes.  If you like it underdone take it out a few minutes early.  You will know they are done when the edges start to turn a golden brown and a toothpick comes out clean when poked in the middle.
  • After baking, let the bars cool completely before frosting.

Chocolate Frosting

  • Add the butter, milk, vanilla, powdered sugar and cocoa to a mixer or bowl and mix fully.  If you need to thin it out, add a bit more milk. If you want it thicker, add more powdered sugar. If you want it a more rich chocolate flavor, add more cocoa!
    You do not have to use all of the frosting! Frost them with as much or as little of the frosting as you like! I like them with a lot of frosting so I use almost all of it, but it is up to you!

Notes

  1. I use quick oats for this recipe.  The quick oats are made so that they don’t need as much cooking time which means they are a bit softer making these bars more moist.  If you use regular steel cut oats you may find your bars to be a bit dry!
  2.  For the cocoa in the frosting, I start with 5 tbsp. and then add more to taste.  You can even add more than 5 to 6 tbsp., it is up to you on how rich you want the chocolate to taste.
  3. For the frosting, start out with 5 cups of powdered sugar and add more as needed to get the right consistency!  You want your frosting to be thin enough to spread with a knife-slightly thick, so it will “set”….but not to thick it can be squished and spread in with your hands like paste or play doh ….that would be just gross!!!  
    You can use as much or as little of the frosting as you like! Use it all, use half or somewhere in between – it’s up to you!
  4.  For a delicious variation, you can spread a layer of creamy peanut butter on the cooled bars before frosting with the chocolate frosting.

      Christy I am so happy to hear you enjoyed them and I’m going to try them in a 9×13 pan so I don’t eat as many 😆 Doesn’t a diet soda make everything taste better 🥰😋😘

    Can’t find the actual recipe???

  7. Have you tried freezing these? I’d like to be able to make them ahead of time for an event.

    • Beth, The Butcher's Wife

      I think it would work great…I have never tried it, but I always freeze cakes and cookies without a problem so I bet it would work great! Let me know if you try it!😘

    I make a similar peanut butter finger, but the ones that we make have a cup or more of chocolate chips on top as soon as you take it out of the oven. When melted from heat of brownies just spread over brownies and let cool and set. Then you frost with peanut butter frosting. Yummy!!

    Hi Beth.
    I have been called crazy for loving diet coke with any chocolate/peanut butter combinations. Happy to hear I’m not alone!!

    • Beth, The Butcher's Wife

      Girl you are not crazy! It’s the most delicious combo! Those that don’t agree are crazy!😉😘

  11. I’m confused with the recipe. Is it 3/4 cup of peanut butter or 1 and 3/4 cups of peanut butter.

    • Beth, The Butcher's Wife

      Hi Doreen! It means you can put in 3/4 to 1 cup- totally up to you… my boys love a lot of peanut butter in them but 3/4 cup is the perfect amount I think! Hope you love them just as much as we do!
