Preheat oven to 325 degrees F. Combine cake mix, melted butter, eggs, pudding mix, vegetable oil and mix well until thoroughly combined (2-3 minutes on medium of electric mixer).

Spray a 9x13 with nonstick cooking spray. I like the baking variety that has flour in it. Then spread the red velvet brownie layer into the pan. It will be VERY thick, use the back of a spoon (or clean hands) to help spread it into all edges of the pan.

Bake for 20-22 minutes or until a toothpick inserted comes out clean (ovens vary so watch closely). Let cool completely before flipping out.

Crush package of Oreos in a food processor (or in a large plastic bag and rolling pin).

Melt cream cheese for 15 seconds in a microwave to soften.

Stir together crushed Oreos and cream cheese until blended smooth.

Carefully spread out Oreo truffle mixture on top of baked red velvet brownies. Use your hands to help press it down instead of spreading to avoid tearing the brownies.

Melt chocolate candy bark (or chocolate chips) and pour over top Oreo truffle layer.

Sprinkle with mini chocolate chips while still warm.

Let cool competely before cutting into squares.
