Mix sour cream, coffee, eggs, vegetable oil, and vanilla extract together. Add in your cake mix. Mix for 2-3 minutes. Fold in your mini chocolate chips.
Pour into a greased 9 x 13 and bake at 350 degrees for 35 minutes.
Once done baking, let the cake rest for 1-2 hours or until the cake is completely cooled.
Oreo Pudding Mix and Whipped Topping
While the cake is cooling crush your Oreos, make your pudding mix according to the package, and whip up your whipped cream mixture.
Bring Everything Together
Poke holes into your cake with the end of a scapula. Pour your pudding mixture over the cake and into the holes. Spread out evenly.
Spread your whipped cream mixture over the pudding mixture and top with your crushed Oreos.
You can eat this right away or let it sit over night in the fridge. Enjoy!
