Oatmeal Butterscotch Whoopie Pies – delicious soft-baked oatmeal butterscotch cookies with a creamy buttercream filling…

Two Oatmeal Butterscotch Whoopie Pies on a glass serving dish with whoopie pies on a cooling rack in the background next to a measuring cup of oats


These delicious whoopie pies consist of two moist and buttery oatmeal cookies speckled with handfuls of rich butterscotch chips (I added in a cup of raisins because I love oatmeal cookies with raisins, but they’re totally optional). Sandwiched between the two cookies is a divine buttercream filling.

  1. Whoopie pies are so nostalgic for me, and this oatmeal version sounds absolutely delicious!

  2. 5 stars
    Smart birthday girl! These would be gone in seconds if they were around me.

  3. I haven’t jumped on the Easter baking bandwagon either. I have a six year old daughter, but all she wants is to dye eggs. I’m totally down with that. I’m also down with these whoopie pies. Love raisins in my oatmeal cookies and the butterscotch chips would make them irresistible.

  4. freaking incredible. the cookies look amazing and sandwiched together the whole package is deliciously fantastic!

  5. These whoopie pie are amazing! I love oatmeal cookies and I’m huge fan of the addition of butterscotch chips….delicious!

  6. The addition of butterscotch–swooning. My dad would go crazy over these and I am going to see him soon, I will have to make these.

  7. I can see why your daughter wanted these for her birthday. The look incredible. I would love them for my birthday too!

  8. Can you make the frosting for the whoopie pies without a paddle attachment? I don’t have one for my very old mixer (it was my grandma’s).

  9. My hubby loves sweets and I’m always looking for something new to make. I’ve never made a Whoopie Pie, but I think it’s time all that changes! YUM!

    1. Thanks, Debra. These are fantastic, easy to make and very hard to resist. I hope you get to try the recipe, I think you and your husband would love them 🙂
