What you need to make Do Si Do style cookies.
Filling.
- Sugar Free Creamy Peanut Butter- Stick to peanut butter that is not organic as the organic tends to have settled oil which can affect this recipe.
- Butter- Softened to room temperature.
- Sugar Free Powdered Sugar- Adds the texture to the filling.
- Almond Milk- Regular milk could also work.
Cookie.
- Flour- Measure this exact by scooping and leveling it.
- Baking Soda- For a bit of leavening.

- Butter- Softened to room temperature.

How to make Copycat Do Si Do Cookies
- Preheat your oven to 325 and prep two baking or cookie sheets for nonstick. I use parchment paper.
- In a medium bowl, use a fork to combine together the flour, baking soda, and salt.
- Next, in a mixing bowl, beat together the butter, sugar free peanut butter, and brown sugar alternative until creamy. Scrape down the sides of the bowl and add the egg and vanilla. Mix until just combined.
- Scrape down the sides of the mixing bowl an slowly add the dry ingredients from the first bowl to the mixing bowl. Mix until just combined. Then use a rubber spatula to fold in the oats.
- Use a small cookie scoop to scoop the batter into balls. Then place the balls on to the baking sheets, leaving plenty of space between cookies for spread. Some folks like to use a toothpick to poke a hole in the center of each cookie for air. These cookies will spread which means that it is best to leave them as balls rather than pressing them into the sheets.
- Bake these cookies until the begin to turn golden brown, about 12-14 minutes.
- Allow the cookies to cool on baking sheet for 10 minutes before transferring them to a wire rack to finish cooling. You can prepare the filling while the cookies cool.
- To assemble the cookies, simply use a piping bag to evenly distribute the filling to the inner โ rds of the insides of half of the cookies. Then, place each of the remaining cookies to finish the cookie sandwich by carefully placing them on top of the filling.
Tips for making the best copycat Do Si Do cookies.
This is a sugar free version of the popular cookie which means that we are using sugar alternatives rather than sugar itself. Granular light brown sugar alternative that measures like regular brown sugar is an important ingredient in this recipe.
Here are some more helpful tips for you.
- This recipe calls for quick cooking oats rather than regular old fashion oats. There is a difference in texture that results when using the different kinds of oats in this recipe, so make sure that you are using the right kind of oats for best results.
- I suggest that you use a piping bag to apply the filling. A piping bag will help with a more even application.
- When whipping up the filling, make sure that it is whipped well with a lot of air. This will make it easier for you to work with.
- These cookies are meant to spread while baking. This is what helps make the sandwich part so crunchy. Take this into account when scooping the cookies and placing them onto the baking sheets for baking.
