The Half Sheet Pan (there is a difference from a jelly roll pan)

Did you know that a half sheet pan is actually a little different than a jelly roll pan? It seems like everyone says jelly roll pan and many times they mean a half sheet pan.

There is actually a bit of a difference. The jelly roll pan is typically a sheet pan or baking sheet that is rimmed and measures about 10×15 inches. While a half sheet pan (what I always use- I don’t even own a jelly roll pan) is rimmed and measures about 13×18 inches.

If you use a jelly roll pan, don’t add the entire bowl of dough or you may have a mess on your hands.

Below there isa link to the half sheet pans I use.

The peanut butter-oatmeal cookie bottom bakes up soft and delicious.

First, add the softened butter and sugars into a stand mixer and mix until blended well.

Next, add the the rest of the ingredients, making sure they are fully blended.

I add more peanut butter because why not?? 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…more is better, trust me!

Finally, press into a greased baking sheet. I use a half sheet pan and this is the perfect size! The pan measures about 18×13 inches. See below for a link to the pan I have.

**If you use a jelly roll pan it is a bit smaller than a half sheet pan, so do not use all of the dough! Take a little bit out and press it into the bottom of the pan… Just so it doesn’t bake over the sides in the oven and leave you with a mess!

See in the photo below to see how much dough you want in the pan. Notice that there is a bit of room from the top of the pressed cookie dough to the top of the pan, leaving room for the dough to rise a bit when it bakes.

Baking the Peanut Butter Fingers

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!

Prep Time: 10 minutes
Cook Time: 15 minutes
Servings: 24 Slices(more or less depending on size)

Equipment

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 pan.
    **See notes below if using a smaller 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. If you are using a jelly roll pan it is smaller than a half sheet pan (you can read about this in the blog post above).  Do not add all of the cookie dough to the jelly roll pan or it will bake over the sides and leave you with a mess.  You can see in the photo above, the dough is pressed  into the bottom of the pan and it fills the sheet pan about half way.  So leave out some of the dough if using a jelly roll pan. The half sheet pans I use are linked above.
  2. 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!
  3.  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.
  4. 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!
  5.  For a delicious variation, you can spread a layer of creamy peanut butter on the cooled bars before frosting with the chocolate frosting.

    I saw it noted about five times that there is a link to the half-sheet pan, but no link. 🙁 This recipe was handed down through my family (with the chocolate chips on top and the peanut butter frosting). It’s a favorite. I like searching the recipes on favorites periodically to make sure nothing has been accidentally dropped or changed. I like the idea about adding more peanut butter – I will try that next time.

  2. Mine are in the oven as I write this, I added mini chocolate chips and 3/4 c chopped peanuts. I’m anxious to try.

    • Beth, The Butcher's Wife

      Hi Tina! I’m so excited you’re trying the Peanut Butter Fingers!!! They are a favorite at our house!!! Mini chocolate and chips and peanuts sound like a delicious addition!!! I hope you like the recipe!!Let me know how they turn out!!❤️😘

    The cookies are delicious but a jelly roll pan was too small. It ran over the edges…quite a mess🙃

    • Beth, The Butcher's Wife

      Oh no!!! I always use a half sheet pan … jelly roll pans are a bit smaller but I haven’t heard anyone having problems with them baking over..I’ll have to add a note to the recipe so other people don’t have the same issue … I’ll note that they may want to leave out some of the dough to be safe if using a smaller jelly roll pan …. Thank you for letting me know! Hopefully others won’t have the same problem!!! I have a link to the half sheet pans I use that the dough will not bake over when you use it… if you’re interested! Im so glad they were delicious but I am sorry about the mess! Thank you for the feedback so I can add it to the recipe!😘

  4. I would like the recipe for root beer cookies

    • Beth, The Butcher's Wife

      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 🥰😋😘

  8. Suzette Szumutku

    Can’t find the actual recipe???

  9. 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!😉😘

  13. 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!
