This Mudslide Poke Cake is a dark chocolate cake soaked in a spiked chocolate ganache and a boozy chocolate pudding with a chocolate mousse topping. It’s rich, chocolatey, and delicious!

Boozy Chocolate Poke
I feel like we know each other well enough by now that I don’t have to tell you just how much I love a boozy dessert…and how much I love a good poke cake. And this Mudslide Poke Cake is both!
This recipe is simple to make but yields the most mouthwatering, decadent dessert. It’s similar to my triple chocolate mousse cake but with a boozy twist. You’ll find layers of both Bailey’s Irish Cream and Kahlua in the chocolate pudding filling, and the chocolate mousse on top.
Does it get better than that?

Key Ingredients
- Chocolate Cake Mix – I like to keep it simple with boxed cake mix, but you can totally whip up a homemade chocolate cake if preferred.
- Coffee – Most cake mixes call for water, but I replaced that with strong brewed coffee. This doesn’t make it taste like coffee, though. It simply enhances the chocolate flavor!
- Liquor – This cake uses both Bailey’s Irish Cream and Kahlua. If you don’t have both on hand, you could technically use one or the other.
- Cool Whip – You can also whip up a batch of homemade whipped cream if preferred.
- Optional Toppings – We’re topping our cake off with a sprinkle of mini chocolate chips and hot fudge sauce.
How to Make Mudslide Poke Cake
This chocolate poke cake is so simple to make and so perfectly mouthwatering! Here’s a breakdown of the recipe:
- Bake the cake: In a bowl, combine the cake mix with oil, eggs, and coffee. Mix until combined, then pour into a 9×13″ baking pan. Bake, then cool for 20 minutes.
- Poke holes: Use the handle end of a wooden spoon or another similar object to poke holes all over the top of the cake.
- Add the ganache: In a bowl, combine chocolate chips and heavy cream. Microwave, stirring occasionally, until melted, then whisk in Bailey’s Irish Cream. Drizzle over the top of the cake.
- Add the filling and chill: In another bowl, combine instant pudding, milk, and Kahlua. Whisk until dissolved, then immediately pour over the top of the cake. Spread with a spatula to make sure the mixture gets into the holes. Let set in the fridge for at least an hour or until completely cooled.
- Make the mousse: In a bowl, combine the chocolate pudding mix, milk, and liquor of choice. Whisk to combine, then place in the fridge to set. Once set, gently fold in the Cool Whip to combine, then spread over the top of the cake.
- Chill and serve: Chill the cake in the fridge for at least another hour, garnish as desired, then slice and serve.

Frequently Asked Questions
I find the easiest way to poke holes is to use the handle end of a standard wooden spoon. It creates holes that are just the right size! If you don’t have a wooden spoon, try using a butter knife or fork.
We’re infusing this chocolate cake with alcohol by simply mixing the alcohol into the ganache, filling and topping, but you’ll also find some baked into the cake as well.
Tips for Success
- Cool before poking. The baked cake should cool for 20 minutes or so before you poke the holes. If you poke while it’s still hot, it will be too messy.
- Don’t let the pudding set. The pudding filling should still be liquid when you pour it over the cake or it won’t actually soak in.
- Cool completely before adding the topping. If you add the mousse while the cake is still warm, it will just melt.
- If you would prefer a non-alcoholic dessert, simply leave the Bailey’s and Kahlua out! The cake will still be delicious.
Make-Ahead and Storage
I’ve said it before and I’ll say it again. Poke cakes are the best make-ahead dessert, because they really just get better as they sit!
A fully assembled poke cake will last covered in the fridge for up to 3 days.
You can also bake the cake ahead of time and store it at room temperature for a couple of days, then add the filling and topping when you’re ready to serve.

- 1 pkg instant chocolate pudding (3.4 0z)
- 1 1/4 cups milk

Instructions
- Preheat the oven to 350°F.
- In a medium-sized bowl, combine the cake mix, oil, egg,s and coffee and mix until the cake batter is well combined. Pour the batter into a 9″x13” pan
- Bake the cake according to the instruction on the box. Allow to cool for 20 minutes.
- Take the end of a wooden spoon or another round object and poke holes all over the top of your cake.
- While your cake is cooling, prepare your ganache. In a heat-proof bowl, combine the chocolate chips and heavy cream. Microwave in 30-second increments, occasionally stirring until the chocolate is melted.
- Whisk in 2 tablespoons of Bailey’s Irish Cream. Drizzle the ganache over the top of the cake.
- In a separate bowl, combine the instant chocolate pudding, milk, and Kahlua together. Whisk until the powder is dissolved. Before the pudding sets, while it is still pourable, pour the pudding over top of the cake and spread with a spatula if necessary.
- Allow the pudding and cake to set in the fridge for at least an hour and the cake is completely cooled. In the meantime, you can prepare your mousse
- For the mousse: In a medium-sized bowl, combine the chocolate pudding mix with the milk and liquor of your choice. Whisk together until combined. Place the pudding in the fridge until it is completely set, 10-15 minutes.
- Once the pudding is set, fold in the Cool Whip and stir until well combined. Spread the mousse over the cooled cake and return to the refrigerator for at least one hour, the longer the better.
- Garnish the cake with mini chocolate chips and drizzle it with hot fudge sauce
Notes
If you don’t have both Baileys and Kahlua, then just use one or the other
