Boxed chocolate cake mix

Eggs (as called for on cake mix box)

Oil (as called for on cake mix box)

Water (as called for on cake mix box)

Canned vanilla icing (1 regular-sized tub)

Oreo cookies (1 standard package)

Instructions

1-Prepare the cake mix: Mix chocolate cake mix with eggs, oil, and water according to package directions; pour into a greased 9×13-inch pan.

3-Crush the Oreos: Crush Oreo cookies in a sturdy freezer bag with a rolling pin to create a mix of fine crumbs and larger chunks.

4-Make the Oreo frosting: Stir room-temperature vanilla icing with the crushed Oreos until evenly combined and slightly fluffy.

5-Frost the cooled cake: Spread the Oreo frosting evenly over the completely cooled cake, working from the center outward with gentle strokes.

6-Add the finishing touches: Arrange mini Oreos on top, dust with cocoa powder, and refrigerate 30 minutes for clean, bakery-style slices.

Notes

๐ŸŒŸ Let the canned frosting sit at room temperature for 30 minutes before mixing for easier blending and smoother spreading.
๐ŸŒŸ Use a sturdy freezer bag instead of a sandwich bag when crushing Oreos to prevent tears and messy spills.
๐ŸŒŸ Refrigerate the frosted cake for 30 minutes before cutting to achieve clean, bakery-style slices.
