Ingredient Notes

Ingredients needed for oatmeal butterscotch cookie bars.

Quick oats. You need the quick cooking (instant) oats for these bars! Do not use old fashioned oats. They are not as finely processed and will affect the texture. If you only have old fashioned oats, pulse a few times in a food processor before measuring.

Unsalted butter. We use unsalted butter to control the salt levels in our recipes. If you only have salted butter, you can use it here instead. Just leave out the added kosher salt in the recipe.

Butterscotch morsels. Also called “butterscotch chips”, you can find these in the baking aisle of your grocery store next to the chocolate chips.

Vanilla Extract. Always choose pure vanilla (not the imitation stuff). Or make homemade vanilla extract and save money!

Easy Instructions

Make the batter.

Beat butter and sugars together until well blended. Beat in eggs and vanilla, followed by the dry ingredients. Fold in the butterscotch morsels.

Bake.

Press the thick cookie batter into a parchment-lined baking sheet. Bake for about 18 minutes.

Add the cinnamon frosting.

Beat butter with the whisk attachment of your electric mixer. When it’s pale and fluffy, beat in powdered sugar, salt, cinnamon.

Add milk, a little at a time, until your desired consistency is achieved.

Spread frosting over the cooled Oatmeal Scotchie Bars. Slice into squares and serve.

Tips and Tricks

  • Want a thicker frosting? Add less milk. Want a thinner, more pourable frosting? Add more milk!
  • Store bars in an airtight container at room temperature for up to 5 days. They’re so hard to resist that they’re likely to get eaten well before then!
  • I prefer these bars a little on the chewier side, so I take them out of the oven when they’re still a little soft. For a crunchier bar, you can leave them in a bit longer.

Recipe FAQs

What size baking pan do I need to make these bars?

We tested the recipe in a 15 x 10 x 1 inch baking sheet. Using a different sized pan will affect the baking time and the thickness of the oatmeal scotchie bars.

Can you freeze oatmeal scotchie bars?

Yes, you can freeze these frosted or unfrosted! They’ll stay good in the freezer for about 2 months. The dough freezes well, too!

Can I use dark brown sugar instead of light brown sugar?

Yes, dark brown sugar will work too.

Comments & Reviews

  1. Aimee, my absolute favorite cookies are Oatmeal Scotchies! Definitely brings back great childhood memories:) I’ve never tried them with frosting, but will be making your recipe soon!

  2. I made these last night and brought them to work today. Big hit! Thanks for another winner and congratulations on moving home.

  3. This recipes sounds wonderful! Scotchie bars bring back happy memories from my childhood because one of my grandmothers used to make “Little Scotties” which is her name for them. I can’t wait to try your recipe! I love that you added frosting to them! YUM!

  4. Ack! I really, really want to make these today! But I just realized I only have two cups of oats! And I don’t have the car to get to the store today. Got any suggestions to sub for 1 cup of oats? Maybe I could just figure out measurements for a 2/3 batch.
