This copycat version of Crumbl's Oreo Raspberry Cheesecake Cookies starts with a Oreo cake mix cookie and ends with a delicious but easy homemade cheesecake frosting and raspberry drizzle.
Preheat the oven to 350°.
In a medium bowl combine the chocolate cake mix, brown sugar, Oreo cookie crumbs and black cocoa powder. Whisk to combine the dry ingredients.
Add the melted butter and eggs to the dry ingredients and mix using a hand held or stand mixer until you have a thick dough.
Use a ¼ measuring cup to measure out dough and form each dough mound into a large disc. Place 6 onto a silicone mat {or parchment} lined baking sheet. Bake for 9-11 minutes or until set. Remove from the oven and allow the cookies to cool completely on the baking sheet. Continue until all of the dough is baked.
Once the cookies have cooled, combine the softened cream cheese and marshmallow fluff in a medium bowl with a hand held mixer until smooth. Add powdered sugar and mix until you have a creamy frosting.
Add frosting to the piping {or zipper} bag and cut a large triangle from the end {or corner}. Pipe a hearty amount of cheesecake frosting to the top of each cookie, starting on the outside of each cookie and working to the middle. Continue until all of the cookies are frosted.
Once all of the cookies are frosted, add raspberry preserves to a piping {or zipper} bag and cut a small triangle from the end {or corner}. Drizzle over the top of each cookie and serve.
Store leftovers in an airtight container in the refrigerator for up to 4 days. Cookies can also be frozen for up to 3 months.
