Ingredients
Method
CAKE
- Prepare the chocolate cake according to the box instructions. Bake in a 9x13-inch pan (or two 9-inch pans) until a toothpick comes out clean. Let it cool completely.
- Once cool, crumble the cake into a large bowl or directly into your serving pan. Aim for a mix of fine crumbs and a few larger chunks for texture.
PUDDING LAYER
- For the first pudding layer, whisk together 3.4 oz chocolate instant pudding mix with 1 3/4 cups cold milk until thickened (about 2 minutes). Spread this pudding evenly over the crumbled cake.
- Sprinkle about half of the crushed Oreos over the pudding, pressing gently so they nestle into the layer.
- In a separate bowl, whisk the second 3.4 oz chocolate instant pudding mix with the remaining 1 3/4 cups milk until set. Fold in the thawed cool whip until smooth and airy.
TOPPING
- Spread the whipped pudding mixture over the Oreo layer in an even layer.
- Warm the hot fudge slightly (15–20 seconds in the microwave) until pourable but not hot. Drizzle the hot fudge over the top in ribbons.
- Finish with the remaining crushed Oreos scattered across the top.
- Chill at least 1 hour before serving to let layers meld; overnight is even better.
Notes
Cool the cake completely before crumbling to prevent a gummy texture. Use cold milk for instant pudding so it sets properly. Gently fold the cool whip into the pudding to keep the topping airy. Warm the hot fudge just enough to drizzle — too hot and it will sink or melt the pudding layer. For cleaner squares, chill well and use a hot knife (dip in hot water and wipe dry between cuts).
