Ingredients
For the Chocolate Cake Base
- 1 box (15.25 oz) chocolate cake mix (any brand)
- Ingredients listed on box: usually 3 large eggs, ½ cup vegetable oil, and 1 cup water
For the Chocolate Milk Filling
- 2 cups (480ml) chocolate milk (homemade or store-bought)
- 1 tub (8 oz / 225g) whipped topping (like Cool Whip), thawed
For the Chocolate Drizzle Finish
- 1 cup (175g) semisweet chocolate chips (high-quality recommended)
Optional Additions & Garnishes
- Crushed Oreos or sprinkles (on top before chilling)
- Fresh berries or banana slices (layered or served alongside)
- Extra dollop of whipped cream per serving
Step-by-Step Instructions
1. Preheat Oven & Prep Pan
- Preheat oven to 350°F (175°C).
- Grease a 9×13-inch baking pan with butter or nonstick spray.
2. Bake the Chocolate Cake
- Prepare cake batter according to package directions (usually mix dry mix with eggs, oil, and water).
- Pour into prepared pan and bake 28–32 minutes, until:
- Top is springy to the touch
- A toothpick inserted in center comes out clean
Let cool in pan 15 minutes—the cake should be warm but not hot.
✅ Warm cake absorbs better —but too hot = collapse.
3. Poke Holes Deeply
Using the handle of a wooden spoon, skewer, or chopstick:
- Poke holes 1 inch apart across the entire surface.
- Push deep—almost to the bottom—to allow filling to seep all the way through.
✅ Don’t skip depth! Shallow holes = soggy top, dry bottom.
4. Mix the Creamy Filling
In a bowl:
- Whisk together chocolate milk and thawed whipped topping until smooth, creamy, and uniform.
✅ No lumps? That’s good—the texture should be silky.
5. Soak the Cake
- Slowly pour the chocolate milk mixture over the poked cake.
- Use a spatula to gently spread and help it sink into the holes.
- Let sit 10 minutes—this gives time for absorption.
6. Melt & Drizzle Chocolate
In a microwave-safe bowl:
- Melt chocolate chips in 30-second bursts, stirring between each, until smooth (~1–2 mins total).
- Let cool slightly, then drizzle or spread evenly over the top using a spoon or offset spatula.
✅ Pro Tip: For neat lines, place melted chocolate in a zip-top bag, snip a corner, and pipe.
7. Chill Until Set
- Cover with plastic wrap and refrigerate at least 2 hours, or overnight for best results.
- The longer it chills, the firmer and more cohesive it becomes.
Serve well-chilled.
✅ Leftovers? Store covered—they stay fresh and delicious for days!
You Must Know
- Use real whipped topping —homemade whipped cream works too, but holds less structure.
- Warm cake = better soak —cold cake won’t absorb the filling properly.
- Melt chocolate gently —overheating causes seizing.
- Tastes better the next day! Flavors deepen and texture firms up beautifully.
- Freezer-friendly? Best fresh—but freeze unfrosted layers up to 3 months.
Storage Tips
- Store covered in the refrigerator for up to 5 days.
- Do not freeze once assembled—the whipped topping may separate upon thawing.
- Freeze cake base separately if desired; assemble and chill when ready.
Ingredient Substitutions
Serving Suggestions
- Serve family-style on a platter with candles.
- Great for potlucks—bring the whole pan!
- Double the batch and freeze half for future joy.
- Pair with coffee, milk, or vanilla ice cream.
