The Giant Candy Bar: Homemade Mounds Poke Cake

Step 1: The Chocolate Base

Preheat your oven according to the cake mix instructions. Prepare the chocolate cake in a 9×13-inch baking pan. Once baked, remove it from the oven and, while still warm, use the handle of a wooden spoon to poke holes across the entire surface of the cake (about 1 inch apart).

Step 2: The Coconut Soak

While the cake is baking, combine the milk, sugar, and shredded coconut in a medium saucepan. Bring to a boil over medium heat, then reduce and simmer for 5 minutes, stirring constantly. Stir in the vanilla extract. The mixture should be thick but pourable.

Step 3: The Infusion

Pour the hot coconut mixture slowly over the warm cake, making sure the shredded coconut finds its way into the holes. This allows the syrup to soak into the sponge, creating a “Mounds” center. Let the cake cool completely.

Step 4: The Glossy Ganache

Place chocolate chips in a small bowl. Heat the heavy cream until it just begins to simmer, then pour it over the chips. Let sit for 5 minutes, then whisk until perfectly smooth and glossy. Pour the ganache over the cooled cake, spreading it to the edges.

Step 5: The Final Set

Refrigerate the cake for at least 1 hour to allow the ganache to firm up. This creates that beautiful contrast between the soft cake and the rich chocolate topping.

Serving and Storage

Serving: Slice into large squares. For an extra tropical touch, sprinkle a little toasted coconut on top of the wet ganache before it sets.

Storage: Because of the milk and coconut filling, this cake must be kept in the refrigerator. Cover it tightly with foil or plastic wrap; it stays moist and delicious for up to 5 days.

Tips: Perfect Poking

Don’t Poke Too Deep: Aim to go about 3/4 of the way through the cake. If you go all the way to the bottom, the liquid can pool under the cake, making the base soggy.
Warm vs. Cold: Pour the coconut mixture over a warm cake, but pour the chocolate ganache over a cooled cake. This ensures the ganache stays shiny and doesn’t melt into the filling.

Variations: Almond Joy Twist

Make it an “Almond Joy”: Add a layer of whole toasted almonds on top of the coconut filling before pouring the chocolate ganache over them.
Darker Decadence: Use a “Devil’s Food” cake mix and dark chocolate chips (70% cocoa) for a more intense, less sweet flavor profile.
Coconut Milk Swap: Use canned coconut milk instead of whole milk in the filling for an even more intense coconut aroma.

Conclusion: A Crowd-Sized Candy Bar

The Mounds Candy Bar Poke Cake is a celebration of texture. It transforms a standard box mix into a gourmet experience by focusing on the “soak.” Each bite gives you the moistness of a tres leches cake, the chew of a macaroon, and the indulgence of a truffle. It’s the perfect dessert for potlucks or birthday parties because it looks impressive but is remarkably difficult to mess up. Just be prepared to watch that glossy chocolate disappear the moment it hits the table!

Frequently Asked Questions

Can I use unsweetened coconut?: Yes, but you may want to increase the sugar in the filling by 2 tablespoons to compensate for the loss of sweetness.
Why is my ganache dull?: This usually happens if the cream wasn’t hot enough or if the chocolate was overheated. For a mirror-like shine, add a teaspoon of corn syrup to the cream before heating.
Can I make this in a Bundt pan?: Poke cakes are best suited for 9×13 pans because they hold the liquid in. A Bundt pan might leak the coconut soak before it has a chance to be absorbed.

Would you like me to suggest a recipe for a “White Chocolate Coconut” version, or perhaps a guide on how to perfectly toast coconut at home?
