Do-Si-Dos cookies are oatmeal cookies with peanut butter filling. These easy cookies are a Girl Scout Do-Si-Do copycat recipe!
This Do-Si-Dohs recipe makes crunch oatmeal cookies with soft peanut butter filling. I made this recipe to replicate the Doh-Si-Dohs from my Girl Scout days.
Normally, I’m not a crunchy cookie person, but those Girl Scouts make a mean oatmeal peanut butter cookie, and these cookies are a great copycat version.
These cookies are the perfect way to satisfy your Girl Scout cookie craving when you can’t get the real thing!
“Love oatmeal and peanut butter together and these taste just like the Girl Scout cookie. Will make these again and again. How about a thin mint? ;)” – Beth
Ingredient notes and substitutions
- Butter: I use salted butter in this recipe. If using unsalted butter, increase the salt to 1/2 teaspoon in the cookies and add an extra pinch of salt to the filling.
- Brown sugar: I use light brown sugar. You could also use dark brown sugar if you prefer.
- Oats: I haven’t tried using quick oats in this recipe.
- Peanut butter: I don’t recommend using natural peanut butter in the filling. It’s difficult to get the correct consistency when using natural peanut butter.
- Milk: Skim to whole milk will work. You can also use a nondairy milk like almond milk.
How to make homemade Do-Si-Dos cookies
Here you’ll find step-by-step photos showing how to make this recipe. The full recipe, including ingredients, is given below.
Step 1: Beat the butter and sugars together in a large mixing bowl until well-combined, about 2-3 minutes on medium.
Step 2: Add the egg, and mix in until combined.
Step 3: Mix in the vanilla extract until incorporated.
Step 4: Add the dry ingredients (oats, flour, baking soda, baking powder, and salt), and mix in just until combined.
Step 5: Drop by tablespoonfuls 2 inches apart on the prepared baking sheets.
Step 6: Bake until golden brown, about 10-15 minutes.
Step 7: Remove the cookies to a wire cooling rack and let them cool to room temperature.
Step 8: To make the peanut butter filling, beat the butter, peanut butter, and powdered sugar together until combined.
Step 9: Stir in the vanilla extract and then enough milk to make a spreadable consistency.
Step 10: Spread the peanut butter filling over half of the cookies. Top with the other half of the cookies.
Recipe Tips!
- Crispy cookies: The cookies should be crispy. If you want softer cookies, bake on the lower end of the baking time.
- Filling consistency: The filling should be thick but smooth. If it is too thick, add 1/2 teaspoon of milk at a time until it reaches the correct consistency. If it’s too thin, add 1 teaspoon of peanut butter at a time until it reaches the desired consistency. You may also need to add a bit more powdered sugar if adding more peanut butter.
Storage
I store these cookies in an airtight container in the refrigerator. They can be stored at room temperature, but they keep better in the fridge.
The cookies will keep up to 5 days when properly stored in the fridge.

You mean the Girl Scouts sell something besides Thin Mints??? I never got beyond the Mints on the list and it looks like I really missed out! Pinned! thanks so much for sharing on Busy Monday!
kateheartseating says
Thanks!! Thin mints are my 4th fav Girl Scout cookie (that tells you how many cookies I’ve eaten in my day). If you haven’t tried any of the others, I’d suggest the Samoas (Caramel Delights), the ones that are like a peanut butter cup, and the Doh Si Dohs. I hope you enjoy these cookies!! =)

omeletta says
I love this! Do-Si-Dos were my all time favorite Girl Scout Cookie eons ago and you just reminded me that I think cookie-selling season is just around the corner, right? I’ll put in my usual order for 50 boxes of Thin Mints but these look like they would be better made at home. thanks!
kateheartseating says
Thanks! It is cookie season (is that a real thing? if not, there should totally be a cookie season). The day after I posted these, I ran into Girl Scouts selling cookies for the first time in years. I was so excited…until they told me that they had just sold the last of their Thin Mints. We still bought a ton of cookies, but I need to see if I can find some of those Thin Mints!
Kate says
My niece is selling Girl Guide cookies at the moment, and I am waiting for my order to arrive, but might just make some of these in the meantime.
