1boxDevil’s Food cake mix(Duncan Hine's is my go to but any 15oz boxed mix will work)
2eggs
½cupoil
16ozVanilla frosting(equivalent to one tub of frosting)
Instructions
Preheat the oven to 350℉ and line two sheet pans with parchment paper.
In a large mixing bowl, add the chocolate cake mix, eggs and oil. Stir just until you can’t see any more dry cake mix.
Using a cookie scoop to make sure all your cookies are the same size, scoop the dough onto your prepared baking tray, leaving about 2” between dough balls.
Bake for 8-10 minutes until you see cracks on the top of the cookies, being careful not to overbake them. Remove from the baking tray and let cool.
Once cooled, use a small scoop or teaspoon measuring spoon to place a dollop of the frosting onto half of the cookies, then top each one with a second cookie, pressing down slightly to make sure the filling is evenly distributed.
Notes
This method will work for making all different flavors of cake mix sandwich cookies. Try lemon cake mix cookies with a lemon filling for something light and fresh or funfetti cake mix cookies with sprinkles.
Once filled the sandwich cookies, can be stored in an airtight container on the counter for up to 5 days. You also freeze the cookies in a zip top bag for up to 3 months. Eat them frozen or let them sit out on the counter to thaw for 10-15 minutes before enjoying.
