Expert Tips
- If you want to add sprinkles to the frosting, make sure you add them once you get the consistency perfect.
- These cookies are great for baking and taking somewhere because they are so quick and easy. If you need a simple dessert cookie, then consider making these!
- Use room temperature ingredients. This helps the butter cream properly to mix with the sugar.
- Chill the dough. The dough can be made days ahead. Keep wrapped in parchment and plastic wrap.
Variations
If you want to change up this recipe, here are a few ideas:
- Add 1 cup of chocolate chips to the cookie dough for extra sweetness. You can use white, milk, or dark chocolate chips to switch things up.
- Use a different flavor of cake mix, like yellow or devil's food. You can experiment to see which kind of cake you like best!
- Try using a buttercream frosting or cream cheese frosting. Switching up the frosting can help change up the cookie really quickly!
- For a fun twist, dip the cookies in melted chocolate once they're assembled. Again, you can make this white, milk, or dark chocolate.
- Make mini sandwich cookies by using a 1 tablespoon cookie scoop instead of a 1 ½ to 2 tablespoon cookie scoop.
Storing & Freezing
Storing: These cookies are best served the same day they're made, but you can store any leftover cookies in an airtight container. If they are frosted, store in the fridge.
Freezing: You can make these cookies ahead of time, store them in the freezer for up to 3 months. When you're ready to eat them, just let them thaw at room temperature.
Recipe FAQ's
A sandwich cookie has two cookies with a filling in the middle, while a regular cookie is just one cookie. The filling can be anything from icing to chocolate to fruit.
If you want to make a cookie sandwich without two cookies, you can use one cookie and cut it in half. Spread the filling on one half of the cookie and then top with the other half. Another option is to use a graham cracker in place of one of the cookies.
A cookie sandwich is also called a whoopie pie, black-and-white, or icebox cookie.
