Dark, glossy, fudgy, and unapologetically chocolaty, this chocolate poke cake layers boxed mix, pudding, and whipped topping into a gooey snack-dinner-dessert trifecta. With rich cocoa, fluffy vanilla-kissed topping, and a cascade of chocolate chips, it’s like a sheet pan baked itself a hug. Simple, nostalgic, and completely irresistible.
Prep your pan and oven: Preheat oven to 350°F (175°C) and coat a 9x13-inch baking dish with cooking spray (or line with parchment).
Mix up the cake batter: Prepare cake mix batter as directed on the box (usually with eggs, water, and oil). Stir in milk chocolate chips at the end. Spread evenly in the prepared pan.
Bake the cake: Bake for 25–30 minutes, until a toothpick inserted in the center comes out with a few moist crumbs. Remove from oven and let cool for 5 minutes.
Make the pudding: While the cake is baking, whisk together instant pudding mix and milk in a large bowl until smooth and thickening (about 2 minutes). Set aside.
Poke the cake: Using the handle of a wooden spoon, poke holes all over the surface of the slightly cooled cake, spacing about 1 inch apart. Don’t poke all the way through.
Pour and settle the pudding: Pour the pudding mixture slowly over the entire cake, spreading with a spatula and gently tapping the pan to help the pudding sink into holes.
Let it chill: Let the cake cool to room temperature, then cover with plastic and chill in the refrigerator for at least 2 hours (or overnight for best results).
Prepare the topping: In a bowl, gently stir together thawed whipped topping, cocoa powder, and vanilla extract until smooth and fluffy.
Frost and garnish: Spread the chocolate whipped topping over the chilled cake. Sprinkle with semi-sweet chocolate chips for garnish, if desired.
Serve: Cut into squares and serve chilled. Enjoy!
Notes
This cake keeps covered in the fridge for up to 5 days. To freeze, wrap individual squares and store in a zip-top bag for up to 2 months—thaw in the fridge or on the counter before eating.
Feel free to customize the cake mix, pudding flavor, or toppings (crushed cookies, peanut butter, ganache, etc.).
Dairy-free? Swap for non-dairy milk and whipped topping but use full fat for best pudding set.
