1. Start by preheating your oven to 350°F (175°C) and greasing two 8-inch round cake pans. Trust me, you want to avoid any stickiness!
2. In a large mixing bowl, combine the yellow cake mix, water, vegetable oil, and eggs. Mix it all together until smooth and luscious. Now, gently fold in those delicious crushed Oreo cookies. Yum!
3. Next, grab a small bowl and mix together the brown sugar and cinnamon. This aromatic blend is going to give your cake that delightful flavor.
4. Here comes the fun part! Pour half of the cake batter into each pan, sprinkle half of the cinnamon-sugar mixture over the batter, and then pour the rest of the batter on top. Use a knife to create a beautiful swirl with the cinnamon-sugar mix throughout the batter—this will look stunning once baked.
5. Bake your cakes in the preheated oven for about 25-30 minutes, or until a toothpick inserted in the center comes out clean. Once done, let them cool completely before diving into the frosting.
6. Now, let’s make that dreamy Cookies ‘n’ Cream icing! In a mixing bowl, cream together the softened butter and cream cheese until smooth and fluffy. Gradually add in the powdered sugar and cinnamon while mixing. Adjust the consistency by adding milk until you reach that perfect spreadable texture. And don’t forget to fold in more crushed Oreos!
7. Time to assemble! Spread a generous layer of icing on top of one of the cooled cake layers, place the second layer on top, and cover the entire cake with the remaining icing. Go wild with your decoration!
8. Finally, sprinkle some additional crushed Oreos on top for that extra crunch and visual appeal. Now, slice it up and get ready to enjoy this delightful combination of flavors! Happy baking!
