Girl Scout cookies are a favorite of everyone, but while most people love the Thin Mint and Samoa, my dad loves the Do-Si-Do’s. He is visiting this week and requested a copy-cat version of this cookie and I was able to replicate it exactly. He loved them and said they were spot-on! They are a little bigger than the original version, but that’s not a bad thing!!

The crunchy peanut butter oatmeal cookie with a smooth, thick filling makes the perfect cookie! They are so easy to make, the dough doesn’t need any refrigeration, and it is completely mixed by hand. This makes 26 cookies and I recommend scooping them all out before you start baking. I like to use a cookie scoop and place all the dough on wax paper. This will ensure that all the cookies are the same size and they cook evenly. It is also important for making even sandwiches.

These cookies bake for 20 minutes which may seem like a long time, but that is necessary to make sure the cookie is crunchy and can stand up to the filling. I usually prefer soft cookies, but these crunchy cookies are so good!

If you love the Girl Scout version, then you will love these cookies! Easy to make and so irresistible!
