Copycat Girl Scout Do-Si-Dos

When it comes to Girl Scout cookies, there's plenty of debate as to which flavor reigns. Plenty of people think Thin Mints are the best, while Samoas and Tagalongs certainly hold their ranking pretty high as well. But one of the most understated Girl Scout cookies? Do-si-dos.

Do-si-dos are the perfect option for peanut butter lovers, with their crunchy peanut butter cookie exterior and peanut butter filling sandwiched in between. And while you can still get Girl Scout cookies during their season, mid-January through mid-March, this is the ideal solution for Do-si-do lovers for the rest of the year.

This yummy copycat Girl Scout Do-si-dos recipe offers a blast of peanut butter flavor in every bite. Biting into the sandwich cookie offers the perfect texture, with a crunchy exterior and a hint of chewiness in the center, all paired with the salty and sweet combo of the peanut butter filling.

Gather the ingredients for these copycat Girl Scout Do-si-dos

To get started on making your own Girl Scout Do-si-dos at home, you'll want to first gather all of your ingredients.

For the cookies for this recipe, you'll need two sticks of unsalted butter, softened, one cup of white sugar, one cup of brown sugar, two eggs, half a cup of peanut butter, three cups of flour, one teaspoon of baking soda, one teaspoon of salt, and a cup of oats. You can choose to use either quick oats or old-fashioned oats for this recipe. 

To make the filling for the sandwich cookies, you'll need an additional stick of butter, softened, six cups of powdered sugar, two tablespoons of milk, and an additional three tablespoons of peanut butter.

Cream the butter and sugars for these copycat Girl Scouts Do-si-dos

First, start off this Copycat Girl Scout Do-si-dos recipe by preheating your oven to 350 degrees Fahrenheit. That way, it'll be fully up to temperature by the time your cookie dough is ready for baking.

To make the peanut butter-oatmeal cookie dough, start by creaming the butter and sugars. Add the butter into a large mixing bowl, and mix with a hand mixer until fluffy. Then, add in the white sugar and brown sugar, and cream until well combined.

Next, mix in both eggs, and then mix in the peanut butter until all the wet ingredients are fully incorporated.

Add the dry ingredients to finish the cookie dough

Once all of the wet copycat Girl Scout Do-si-dos ingredients are combined, it's time to finish the cookie dough with the dry ingredients. In a separate bowl, add the dry ingredients, except for the oats. Pour in the flour, baking soda, and salt, and stir to combine.

Next, gradually mix the flour mixture into the wet ingredients mixture. Mix continuously until the dough starts to form, and then add in the oats. Continue mixing until a soft cookie dough forms. Don't worry if the dough seems too soft here. 

Bake these copycat Girl Scout Do-si-dos

Once your peanut butter-oatmeal cookie dough is ready, it's time to bake your cookies. Prepare a cookie sheet with parchment paper, or spray it with cooking spray to prevent the cookies from sticking while baking.

Use a small cookie scoop to portion out the dough. Scoop the cookie dough, roll it into a ball of dough in your hands, and flatten it slightly before placing the dough on the prepared cookie sheet. These cookies will certainly spread a bit, so be sure to keep your balls of dough fairly small. Repeat until all dough has been used.

Bake the cookies for 15 to 17 minutes until the edges and tops are lightly browned. Remove the cookies from the oven and allow them to fully cool on the cookie sheet.

Make the peanut butter filling for these copycat Girl Scout Do-si-dos

One of the highlights of these copycat Girl Scout Do-si-dos is definitely the peanut butter filling. Sure, you can have a delicious peanut butter cookie, but it's the filling sandwiched between the two cookies that truly makes these cookies special.

To make the filling for these cookies, start by mixing the butter in a large mixing bowl. Break up the butter, and then add in two cups of powdered sugar. Continue mixing the butter and sugar, and then add in the milk. Continue gradually adding in the rest of the powdered sugar until your frosting begins to form, and then mix in the peanut butter. Turn the speed up on the mixer to whip the frosting until smooth and fluffy.

Assemble your copycat Girl Scout Do-si-dos

Once your copycat Girl Scout Do-si-dos have cooled and your peanut butter filling is ready, it's time to assemble your cookies. Be sure the cookies are fully cooled before beginning this step. Any hint of warmth on the cookies will melt the filling during assembly. 

Match the cookies up into like-size pairs. Pipe or spread the peanut butter filling onto one cookie, and then top it with its match. Press down slightly to form a sandwich cookie. Repeat until all of your cookies have been matched up and turned into sandwich cookies.
