I made the chocolate truffle filling that I used on my cake for my International Progressing Dinner that I made for 24, 24, 24 back in October and just added the crushed mint oreos to it. Absolutely fantastic!
I have made this with a cream cheese frosting, which was amazing too, but this time I made a normal buttercream frosting with 1/3 C softened butter, 2 C powdered sugar and enough milk to make the desired texture, but instead of milk this time, I used irish cream and then added lots of crushed mint oreos to it. I didn't want to waste the leftover frosting so I made homemade oreos and stuck the frosting in the middle. A few years ago my BFF's little sister made the cutest little homemade oreos that were the smallest things I have ever seen for a baby shower favor. They were so tasty and so cute and ever since then I always make my homemade oreos miniature. These are actually just about 1 inch in diameter. I guess I feel like I can eat more if they are smaller!
The homemade oreos are made with 1 box of devils chocolate cake mix, 3/4 C shortening, and 2 eggs. Mix well, roll into balls and flatten slightly before baking at 350. The size you choose to make will determine the cook time. I cook my tiny ones for 3-5 minutes. You will just have to watch them closely.
